Climate Change

The world is warming up, with 2023 being by far the hottest year since record keeping began and 2024 shaping up to be hotter yet. But these changes only involve one or two degrees. What's the big deal?

The amount of energy required to raise the temperature of one liter of water by one degree is one kilocalorie (kcal). Scaling up, the amount of energy required for a one-degree increase in the water temperature of the Gulf of Mexico is 2,434,000,000,000,000,000 kcals. That's 25 million times more energy than released by the WW-II atomic bomb that destroyed the city of Hiroshima and killed more than 100,000 people.

So, for every one degree increase in water temperature, the Gulf of Mexico takes on 25-million atomic bombs worth of new energy, which is then available to fuel hurricanes and other storms. Maybe a one-degree rise in temperature is a big deal.

Historic rewiring of grass flowering time pathways and implications for crop improvement under climate change.

The New phytologist [Epub ahead of print].

Grasses are fundamental to human survival, providing a large percentage of our calories, fuel, and fodder for livestock, and an enormous global carbon sink. A particularly important part of the grass plant is the grain-producing inflorescence that develops in response to both internal and external signals that converge at the shoot tip to influence meristem behavior. Abiotic signals that trigger reproductive development vary across the grass family, mostly due to the unique ecological and phylogenetic histories of each clade. The time it takes a grass to flower has implications for its ability to escape harsh environments, while also indirectly affecting abiotic stress tolerance, inflorescence architecture, and grain yield. Here, we synthesize recent insights into the evolution of grass flowering time in response to past climate change, particularly focusing on genetic convergence in underlying traits. We then discuss how and why the rewiring of a shared ancestral flowering pathway affects grass yields, and outline ways in which researchers are using this and other information to breed higher yielding, climate-proof cereal crops.

Assessing the geographical diversity of climate change risks in Japan by overlaying climatic impacts with exposure and vulnerability indicators.

The Science of the total environment, 959:178076 pii:S0048-9697(24)08234-2 [Epub ahead of print].

Understanding multifaceted climate change risks and their interconnections is essential for effective adaptation strategies, which require comprehensive assessments of both climatic impact variations and social-environmental exposures/vulnerabilities. This study examines these interconnections and creates multitier delineations of future climate risks across Japan by overlaying homogeneous impact zones (HIZs) with exposure-vulnerability complexes (EVCs). We delineated eight EVC regions, each exhibiting similar patterns of exposure and vulnerability, via multivariate clustering and similarity search on the basis of future population and land cover/use data. Under the Shared Socioeconomic Pathway 5 scenario, 8.07 % of Japan's area was identified as urban, 66.18 % as forest, and 16.66 % as agricultural land, depending on vulnerability and exposure characteristics. We then spatially intersected these EVCs with six HIZs, which represent common patterns of multisectoral climatic impact variations. This intersection revealed low geographical correspondence between climatic impact variations and exposure-vulnerability factors, indicating high spatial variability in climate risk across Japan. The use of EVCs helps identify areas with anticipated climate change risks. The spatial nexus between HIZs and EVCs underscores the geographical complexity and diversity of climate risks, revealing regions with high-impact variations alongside significant exposures and vulnerabilities. For example, urban EVCs highlight critical issues such as heat-related mortality and flood damage. By mapping these impact variations while focusing on exposure and vulnerability disparities, insights from HIZs and EVCs can inform future climate risk management and effective adaptation strategies at the national and regional levels.

Effects of climate change on the occurrence and distribution of Western equine encephalitis virus in South America.

Public health, 239:1-8 pii:S0033-3506(24)00527-4 [Epub ahead of print].

OBJECTIVES: The Western equine encephalitis virus (WEEV) is a globally relevant vector-borne pathogen that causes encephalitis. The role of environmental variables in the epidemiology of WEEV has become greater in the context of climate change. In December 2023, a significant resurgence of WEEV began in South America, with major ongoing outbreaks in Argentina and Uruguay. In this study, we employed a machine learning algorithm to model the distribution of WEEV in South America, considering both present and future scenarios.

STUDY DESIGN: Ecological retrospective study.

METHODS: We conducted a modelling study to identify areas with the highest prevalence of WEEV in South America, based on confirmed human and equine cases during the 2023/2024 outbreak and climatic variables. Our analysis utilised Maxent software, a machine learning algorithm for species distribution modelling.

RESULTS: Our results indicate that environmental variables, particularly thermal seasonality and annual rainfall, can directly influence the occurrence of WEEV, leading to increased virus incidence. Consequently, high-risk areas may shift in the future. Countries, such as Paraguay, Venezuela, Colombia, and various regions in Brazil, particularly the Northeast, Midwest, and the Pantanal biomes, will be significantly impacted, drastically altering the current distribution of WEEV.

CONCLUSIONS: The ongoing WEEV outbreak in South America is concerning because it coincides with migratory bird stopovers. These birds are natural hosts that can spread the virus to unaffected areas. Our results will help to identify priority areas for developing preventive measures and establishing epidemiological surveillance.

Interactive effects of nitrogen deposition and climate change on a globally rare forest geophyte.

Plant biology (Stuttgart, Germany) [Epub ahead of print].

Nitrogen (N) deposition and climate change are both known to threaten global biodiversity. However, we still have a limited understanding of how interactions between these global change drivers affect individuals and populations of specialist species, such as geophytes, within their natural habitat. We explored possible interactive effects of N, drought, and warming on population vitality (mean leaf length, leaf density, flowering probability) and morpho-physiological traits (e.g., leaf and bulb size, N allocation to leaves and bulbs) of the globally rare forest geophyte Gagea spathacea (Liliaceae) in deciduous forests of northern Germany by applying experimental N addition across a climate gradient over a 5-year period. Mean leaf growth and leaf density were not affected by N addition but were enhanced by warmer and drier conditions in the months before leaf emergence. N addition increased N allocation of individual plants towards their subterranean bulbs. Importantly, effects of N addition on morpho-physiological traits depended on warming and drought, with N-fertilized plants showing increased leaf length and decreased specific leaf and bulb N concentration after drier autumns and warmer winters. This indicates that N deposition may partially compensate for increased N demands during warming-induced growth, although this growth-promoting interaction effect is not (yet) reflected in population vitality. Our results highlight the importance of considering multiple global environmental change drivers and a whole plant perspective (above- and belowground traits) to predict long-term growth responses of (endangered) forest spring geophytes and to develop adapted long-term protection strategies.

Perceived indicators of climate change in Tanzania: insights from the university of Dodoma students.

BMC ecology and evolution, 24(1):149.

BACKGROUND: Understanding local communities' knowledge and insights is essential for developing effective mitigation and adaptation strategies for climate change. The young generation often brings new perspectives on climate change, demonstrating a growing awareness of its impacts and innovative ideas for sustainable solutions. By engaging youth in climate action we foster future leadership, empowering them as active participants in shaping long-term climate resilience. Higher education plays a pivotal role in raising awareness about climate change and fostering environmentally responsible behaviour among citizens. Thus, the study assessed climate change indicators in Tanzania by gathering insights from university students, leveraging their understanding of the local challenges posed by climate change.

RESULTS: Out of the 486 sampled students, 80% were aware of climate change and could identify its indicators in their home regions. The primary perceived indicators of climate change reported by the respondents included increasing temperatures, crop failures, and the disappearance of native plant species. Respondents from the coastal zone ranked rising temperatures and increased rainfall as the most significant indicators, while those from the Kilimanjaro region emphasised crop failure. Additionally, respondents from the central zone highlighted the disappearance of native plant species. Conversely, respondents from the arid central zone believed that climate change has resulted in reduced rainfall and an increase in drought occurrences. Furthermore, socio-demographic factors such as gender, home region, and academic year influenced students' awareness of climate change. A lower proportion (0.78) of male students demonstrated knowledge of climate change compared to female students (0.91) (p = 0.001). Additionaly, a lower proportion (0.71) of students from urban areas demonstrated knowledge of climate change compared to students from rural areas (0.85) (p < 0.001). Moreover, students in their final year of study exhibited greater awareness of climate change than those in lower years, highlighting the significance of the formal education system in imparting knowledge about climate change.

CONCLUSIONS: This study underscores the role of higher education in fostering climate awareness and youth engagement through education and outreach. Additionally, it supports SDG 13: "Climate Action" and SDG 4: "Quality Education by promoting informed participation and sustainable solutions among young people".

R290-Hydrofluoroolefin based low global warming potential refrigerant mixtures for room air conditioner: An energy, exergy, and environmental (3E) analysis.

Environmental science and pollution research international [Epub ahead of print].

Among the numerous residential appliances, window or split air conditioners are the most prevalent. The hydrochlorofluorocarbon and hydrofluorocarbon refrigerants used in those systems are causing a serious threat to the environment. In this study, R290-hydrofluoroolefin (HFO) mixtures are proposed as replacements for high-GWP substances (R410A and R22) in window air conditioning (WAC) units. Low-flammability alternatives like R290-R1234yf (50:50 and 60:40 by mass) and R290-R1234ze(E) (50:50 and 60:40 by mass) mixtures were considered promising refrigerants for this study. Using the REFPROP 10.0 refrigerant database and MATLAB-based mathematical modelling, the energy and exergy performance of a WAC unit with proposed and existing refrigerants was investigated. The results demonstrated that R290-HFO mixers performed well, with coefficients of performance that were 5.1-11.9% and 10.8-17.0% higher than those of R22 and R410A, respectively. In a similar fashion, the exergy efficiency of the WAC system increased by 3.1% to 6.2%, with reductions in total exergy degradation and power consumption of 7.1% to 12.2% and 5.1% to 10.1%, respectively. An assessment of the total equivalent warming impact revealed that the use of R290-HFO compounds results in CO2 emissions that are between 7.1 and 12.2% less than those of R22. Mini or microchannel heat exchangers for conventional evaporators and condensers can further decrease the predicted refrigerant change quantity for these mixtures, keeping it well below the IEC 60335-2-89 limit for flammable refrigerants.

The consequences of climate change and male reproductive health: A review of the possible impact and mechanisms.

Biochemistry and biophysics reports, 41:101889.

A global decline in male fertility has been reported, and climate change is considered a major cause of this. Climate change refers to long-term shifts in temperatures and weather patterns, and results from greenhouse gas emissions like carbon dioxide and methane that act as a blanket wrapped around the earth, trapping heat and elevating temperatures. Sad to say, the consequences of climatic variation are beyond the dramatic elevated temperature, they include cold stress, increased malnutrition, air pollution, cardiovascular diseases respiratory tract infections, cancer, sexually transmitted infections, mental stress, and heat waves. These negative effects of climate change impair male reproductive function through multiple pathways, like ROS-sensitive signaling, suppression of steroidogenic markers, and direct damage to testicular cells. The present study aimed to describe the impact of the consequences of climate change on male reproductive health with details of the various mechanisms involved. This will provide an in-depth understanding of the pathophysiological and molecular basis of the possible climatic variation-induced decline in male fertility, which will aid in the development of preventive measures to abate the negative effects of climate change on male reproductive function.

Eruptive Insect Outbreaks from Endemic Populations Under Climate Change.

Bulletin of mathematical biology, 87(1):16.

Insects, especially forest pests, are frequently characterized by eruptive dynamics. These types of species can stay at low, endemic population densities for extended periods of time before erupting in large-scale outbreaks. We here present a mechanistic model of these dynamics for mountain pine beetle. This extends a recent model that describes key aspects of mountain pine beetle biology coupled with a forest growth model by additionally including a fraction of low-vigor trees. These low-vigor trees, which may represent hosts with weakened defenses from drought, disease, other bark beetles, or other stressors, give rise to an endemic equilibrium in biologically plausible parameter ranges. The mechanistic nature of the model allows us to study how each model parameter affects the existence and size of the endemic equilibrium. We then show that under certain parameter shifts that are more likely under climate change, the endemic equilibrium can disappear entirely, leading to an outbreak.

Human driven climate change increased the likelihood of the 2023 record area burned in Canada.

NPJ climate and atmospheric science, 7(1):316.

In 2023, wildfires burned 15 million hectares in Canada, more than doubling the previous record. These wildfires caused a record number of evacuations, unprecedented air quality impacts across Canada and the northeastern United States, and substantial strain on fire management resources. Using climate models, we show that human-induced climate change significantly increased the likelihood of area burned at least as large as in 2023 across most of Canada, with more than two-fold increases in the east and southwest. The long fire season was more than five times as likely and the large areas across Canada experiencing synchronous extreme fire weather were also much more likely due to human influence on the climate. Simulated emissions from the 2023 wildfire season were eight times their 1985-2022 mean. With continued warming, the likelihood of extreme fire seasons is projected to increase further in the future, driving additional impacts on health, society, and ecosystems.

Climate change linked to vampire bat expansion and rabies virus spillover.

Ecography, 2024(10):.

Bat-borne pathogens are a threat to global health and in recent history have had major impacts on human morbidity and mortality. Examples include diseases such as rabies, Nipah virus encephalitis, and severe acute respiratory syndrome (SARS). Climate change may exacerbate the emergence of bat-borne pathogens by affecting the ecology of bats in tropical ecosystems. Here, we report the impacts of climate change on the distributional ecology of the common vampire bat Desmodus rotundus across the last century. Our retrospective analysis revealed a positive relationship between changes in climate and the northern expansion of the distribution of D. rotundus in North America. Furthermore, we also found a reduction in the standard deviation of temperatures at D. rotundus capture locations during the last century, expressed as more consistent, less-seasonal climate in recent years. These results elucidate an association between D. rotundus range expansion and a continental-level rise in rabies virus spill-over transmission from D. rotundus to cattle in the last 50 years of the 120-year study period. This correlative study, based on field observations, offers empirical evidence supporting previous statistical and mathematical simulation-based studies reporting a likely increase of bat-borne diseases in response to climate change. We conclude that the D. rotundus rabies system exemplifies the consequences of climate change augmentation at the wildlife-livestock-human interface, demonstrating how global change acts upon these complex and interconnected systems to drive increased disease emergence.

Predicting the potential distribution of Astragali Radix in China under climate change adopting the MaxEnt model.

Frontiers in plant science, 15:1505985.

INTRODUCTION: Astragali Radix is the dried root of Astragalus mongoliae or Astragalus membranaceus, a leguminous plant. Since ancient times, Astragali Radix has been widely used in Chinese traditional Chinese medicine. As people become more health-conscious, the market demand for Astragali Radix grows and its popularity is increasing in the international market. As an important medicinal plant, the growth of Astragali Radix is strongly influenced by environmental conditions. In order to meet the market demand for high quality Astragali Radix herbs, it is necessary to search and find areas suitable for the growth of Astragali Radix.

METHODS: In this study, we assessed the potential impacts of climate change on the distribution of the Chinese medicinal plant Astragali Radix using the maximum entropy (MaxEnt) model in combination with a geographic information system(GIS). Distribution data and environmental variables were analyzed to predict suitable areas for Astragali Radix under the SSP126, SSP245 and SSP585 scenario for current and future (2041-2060, 2061-2080, 2081-2100). Jackknife is used to assess the importance of environmental variables, and environmental variables with a model contribution greater than 5% were considered to be the main drivers.

RESULTS: The results showed that the current area of suitable area for Astragali Radix is 188.41 km[2], and the three climate scenarios show an increasing trend in the future, with a maximum of 212.70 km[2]. North China has always been the main suitable area, while the area of suitable area in Southwest China is decreasing, and Xinjiang will be developed as a new suitable area in the future. Annual precipitation (41.6%), elevation (15.9%), topsoil calcium carbonate (14.8%), annual mean temperature (8.3%), precipitation seasonality (8%) and topsoil pH (6%) contributed more to the model and were the main environmental influences on the distribution of Astragali Radix. In addition, the centroids of the suitable areas shifted northward under all three climate scenarios, indicating a migratory response to global warming.

DISCUSSION: Our study found that suitable area of Astragali Radix has been expanding for most of the time in each period of the three climate scenarios compared with the current situation. In the future, humans can focus on enhancing the cultivation techniques of Astragali Radix in these suitable areas. This study provide a scientific basis for the development of planting strategies and spatial distribution management of Astragali Radix. It helps to optimize the selection of planting areas and resource conservation of Chinese herbs.

The Effect of Climate Change on Allergen and Irritant Exposure.

The journal of allergy and clinical immunology. In practice pii:S2213-2198(24)01262-5 [Epub ahead of print].

As the effects of anthropogenic climate change have become more apparent, the influences of climate and extreme weather events on health have continued to gain attention. The fact Earth has warmed over the past century is indisputable and the rate of warming is more alarming. As a result of anthropogenic climate change an alteration in the air mixture has occurred over time. These changes have increased human exposures to respiratory irritants such as ground level ozone, volatile organic compounds, nitrogen dioxide, sulfur dioxide, carbon monoxide, and polycyclic aromatic hydrocarbons. A significant amount of research has investigated the effects of climate change on aeroallergens which has shown elevated temperatures and increased carbon dioxide (CO2) levels have produced prolonged and more robust pollen seasons for most taxa studied. In addition, it appears possible that exposure of some plants to air pollution may result in more allergenic pollen. Increased human exposures to these respiratory irritants and aeroallergens appears to disproportionality effect vulnerable populations throughout the world. It is essential to understand climate change is more than an environmental inconvenience and realize the effects to human health are directly related and conceivably immeasurable. It's vital to conduct additional research related to climate change and health which is collaborative, multisectoral and transdisciplinary. There should be a focus on risk reduction, mitigation and preparedness for climate change and extreme weather events for all populations around the globe.

Plastic pollution and marine mussels: Unravelling disparities in research efforts, biological effects and influences of global warming.

The Science of the total environment, 959:178078 pii:S0048-9697(24)08236-6 [Epub ahead of print].

The ever-growing contamination of the environment by plastics is a major scientific and societal concern. Specifically, the study of microplastics (1 μm to 5 mm), nanoplastics (< 1 μm), and their leachates is a critical research area as they have the potential to cause detrimental effects, especially when they impact key ecological species. Marine mussels, as ecosystem engineers and filter feeders, are particularly vulnerable to this type of pollution. In this study, we reviewed the 106 articles that focus on the impacts of plastic pollution on marine mussels. First, we examined the research efforts in terms of plastic characteristics (size, polymer, shape, and leachates) and exposure conditions (concentration, duration, species, life stages, and internal factors), their disparities, and their environmental relevance. Then, we provided an overview of the effects of plastics on mussels at each organisational levels, from the smaller scales (molecular, cellular, tissue and organ impacts) to the organism level (functional, physiological, and behavioural impacts) as well as larger-scale implications (associated community impacts). We finally discussed the limited research available on multi-stressor studies involving plastics, particularly in relation to temperature stress. We identified temperature as an underestimated factor that could shape the impacts of plastics, and proposed a roadmap for future research to address their combined effects. This review also highlights the impact of plastic pollution on mussels at multiple levels and emphasises the strong disparities in research effort and the need for more holistic research, notably through the consideration of multiple stressors, with a specific focus on temperature which is likely to become an increasingly relevant forcing factor in an era of global warming. By identifying critical gaps in current knowledge, we advocate for more coordinated interdisciplinary and international collaborations and raise awareness of the need for environmental coherence in the choice and implementation of experimental protocols.

Impact of urban biodiversity and climate change on children's health and well being.

Pediatric research [Epub ahead of print].

In recent decades, biodiversity loss has greatly impacted planetary and human health. Children are at additional risk of adverse effects due to unique biological, developmental, and behavioral factors, as well as their longer exposure to an altered planet as a function of their young age. These effects are heightened for children living in vulnerable socioeconomic conditions. Here, we review the role of biodiversity loss on accelerating the consequences of climate change from the perspective of pediatric health. With the loss of biodiversity's protective role against the consequences of climate change, the adverse effects of the changing planet are impacting pediatric health. For example, trees provide shelter against heat waves, unsealed soil and wetlands mitigate flooding, and rewilded green space hosts high microbial richness and consequently supports immune and mental health. The effects of the loss of biodiversity may impact the discovery and development of novel pharmaceuticals and thus the future of children's medicine as a whole. We also highlight areas for further study and detail efforts that have been made to restore biodiversity, with the aim to improve the current and future health of local pediatric populations. IMPACT: Loss of biodiversity is occurring at a rapid pace affecting the health of the planet and disproportionately pediatric health. This paper describes the role of biodiversity loss in accelerating the impact of climate change on children's health, and highlights particularly vulnerable populations. This paper details steps that can be taken to maintain and restore biodiversity at the local and global levels to protect these populations and pediatric health in general.

Global climate change and its impact on the distribution and efficacy of Bacillus thuringiensis as a biopesticide.

The Science of the total environment, 958:178091 pii:S0048-9697(24)08249-4 [Epub ahead of print].

This study is the first modeling exercise to assess the impacts of climate change on the current and future global distribution of Bacillus thuringiensis (Bt). Bt is a common Gram-positive, rod-shaped bacterium widely distributed in various environments, including soil and water. It is widely recognized as a source of effective and safe agricultural biopesticides for pest management in various climatic regions globally. In the present work, ensemble species distribution models were developed for Bt based on the generalized linear model (GLM), generalized boosting model (GBM), random forest (RF), and maximum entropy (MaxEnt) under two distinct scenarios, SSP2-4.5 (optimistic) and SSP5-8.5 (pessimistic) for the year of 2050, 2070, and 2090. The performance of our models was evaluated based on true skill statistics (TSS) and the area under the receiver-operator curve (AUC) indices. Both AUC and TSS values were observed in an acceptable range, with AUC at 0.84 and TSS at 0.512, respectively. Results indicate that most of the areas currently suitable for Bt will likely remain stable in the future, particularly Central America, Central and South Africa, South Asia, and parts of Oceania. Norway, Peru, and the UK will have notable habitat gains by 2090 based on SSP2-4.5 and SSP5-8.5 scenarios. On the contrary, Serbia, Guinea, Poland, Croatia, Spain and Romania showed notable losses under both scenarios. Our results underscore Bt potential to improve pest control, crop yields, and environmental sustainability, especially in regions where agriculture is predominant. Our research highlights the need to understand ecological dynamics for future conservation and agricultural planning in the face of climate change.

Shellfish and algae: Climate change mitigation through green and valuable foods.

The Science of the total environment, 959:177987 pii:S0048-9697(24)08144-0 [Epub ahead of print].

Food safety issues have become increasingly severe, while the global population continues to grow. Shellfish and algae (SA), as sustainable and environmentally friendly foods, have great significance in helping countries worldwide achieve the goal of carbon neutrality. However, there is still a gap in quantitatively evaluating the carbon neutrality of SA farming. To address this gap, this study evaluated global SA farming, including aspects of carbon sinks, the drivers of carbon removal, value-added ecosystem services, and the performance of carbon reduction mechanisms. Results revealed that (1) 16.57 Mt. CO2-eq/yr were sequestered worldwide via SA farming during 2000-2020, wherein Asia was the dominant contributor to SA carbon sinks due to the abundance of production. (2) Product values were the main drivers for carbon sinks via SA farming. (3) The annual added value of SA was 501.40 million dollars during 2000-2020, of which algae farming accounted for the highest proportion. Mussel and laver were promising due to their excellent ability for carbon removal and added value. (4) It is estimated that SA farming can reduce carbon within a range from 47.72 Mt. CO2-eq/yr to 1539.95 Mt. CO2-eq/yr in 2021-2035. In general, the farming of SA is a promising way to respond to the call for carbon neutrality and food safety assurance worldwide, while the preference for mussel and laver can be further explored.

Using Animal Welfare Framing as an Effective Approach to Communicating Climate Change-A Review.

Veterinary medicine and science, 11(1):e70154.

INTRODUCTION: Climate change and its effects continue to threaten the stability of environments worldwide, impacting nearly every species. Although framing is an established technique in climate communication science, little has been done in communicating the climate change effects from an animal welfare perspective.

OBJECTIVES: The primary objective of this article is to present the synthesis of evidence in existing literature on the effects of communicating climate change as an animal welfare issue.

METHODS: A systematic approach was taken based on the PRISMA (Preferred Reporting Items for Systematic reviews and Meta-Analyses) scoping review guidelines and utilizing a hybridized ProPheT-PICOS Model with modifications. Using search strings, scholarly databases within the Web of Science platform were systematically searched for English-language climate change literature that included animal welfare concepts. Articles were imported into Covidence and inclusion and exclusion criteria were then used to select articles for further analysis.

RESULTS: Of an initial 4080 studies, only two papers were identified that used animal welfare framing to discuss climate change based on the inclusion/exclusion criteria.

CONCLUSION: Further research should attempt to understand and approach framing climate change concerning current understanding by geographic location and culture to close research gaps and mitigate bias in the context of climate change and its effects on animal welfare.

Estimating global geographical distribution and ecological niche dynamics of Ammannia coccinea under climate change based on Biomod2.

Scientific reports, 14(1):30579.

Invasive alien plants pose a significant threat to biodiversity and the agricultural economy. The invasive weed (Ammannia coccinea) competes with rice in paddy fields, potentially threatening rice production. Despite the crucial need to estimate the global geographical distribution and ecological niche dynamics of A. coccinea for effective early warning, control strategies, and global rice security, relevant research remains scarce. This study utilized the Biomod2 platform, which integrates multiple single models into ensemble model, incorporating environmental and species data to analyze the distribution range shifts of A. coccinea under current and future climate scenarios. It also quantified and analyzed shifts in the species' ecological niche across these climate scenarios. The results indicated that the potential suitable areas for A. coccinea were mainly in Southern North America, northern and south-eastern South America, south-western Europe, the Middle East, central Africa, western Asia, south-eastern Asia, with a gradual increase in mid-high suitability habitat over time and radiation levels. While the overall ecological niche of A. coccinea remains stable, minor shifts are expected under future conditions. Temperature, precipitation, and the human impact index were the key factors influencing the future distribution of A. coccinea. Climate change contributes to the expansion of A. coccinea's highly suitable areas and shifts its ecological niche. Organizations efforts should focus on preventing the spread of A. coccinea in regions where its potential distribution overlaps with key rice production areas. The findings of this study provide critical insights into the global distribution and ecological niche dynamics of A. coccinea, aiding in the development of early warning and control strategies to mitigate its impact on biodiversity, agriculture, and particularly rice production under future climate scenarios.

Valuation of marine integrated disaster management amidst global warming in Southern Coast of Java, Indonesia.

Marine pollution bulletin, 211:117446 pii:S0025-326X(24)01423-1 [Epub ahead of print].

This research explores the valuation of integrated disaster management in the coastal regions of Southern Java, Indonesia, a locale increasingly threatened by the impacts of global warming, which exacerbates marine disasters such as earthquakes and tsunamis. Employing a choice experiment methodology, the study assesses the willingness to pay among local households for various strategies designed to enhance earthquake preparedness. Three distinct scenarios are examined, each reflecting varying levels of integration and sophistication: (1) Educational empowerment and localized alert integration, which emphasizes community education and rapid, self-directed evacuation practices tailored to the immediate onset of tsunamis following seismic events. This scenario advocates for the '20-20-20' rule, underscoring self-evacuation as the most dependable survival method; (2) Strategic evacuation enablement, focusing on the logistics of evacuation and infrastructure development to facilitate timely community response; and (3) Integrated marine disaster management, which merges educational, technological, logistical, and ecological elements into a comprehensive strategy.

Public health professionals' views on climate change, advocacy, and health.

Journal of communication in healthcare [Epub ahead of print].

BACKGROUND: Public health professionals (PHPs) are seeing an increased impact of climate change on the physical and mental health of their communities. Diverse climate change strategies and interventions are needed to equitably protect people's health. Yet, limited information exists on U.S. health professionals' willingness to communicate with the public about climate change and act on the issue.

METHODS: We used a pre-existing survey to assess the willingness of 173 PHPs to participate in climate change advocacy. Variables included beliefs, attitudes and risk perceptions of climate change, perceptions of the local impact of climate change on health, communication barriers and resources for communicating about climate change and health, and the perceived role of PHPs in mitigating climate change.

RESULTS: Key findings included: (1) Belief in climate change is not unanimous among PHPs; (2) PHPs are worried about climate change (93.3%) and agree the issue of climate change is of personal importance (97.1%); (3) Participants are seeking resources/trainings (57.8%) on climate change (4)The main barriers of advocating for climate change are lack of time (54.3%) and knowledge (46.3%); (5)) Respondents acknowledge health impacts due to weather-related events are caused by human activities (83.2%) and (6) views of climate change are determined by willingness to advocate and take action to mitigate climate change (R[2] = .251; p = < .001).

CONCLUSIONS: Although the majority of PHPs believe climate change is happening, this belief is not unanimous and steadfast. Opportunities remain on how health professionals can better inform, educate, and empower others about climate change and health.

Climate change and contagion: the emerging threat of zoonotic diseases in Africa.

Infection ecology & epidemiology, 15(1):2441534.

This article investigates the escalating occurrence of zoonotic diseases in Africa, attributing their spread to climate change and human activities. Africa's unique combination of biodiversity, reliance on animal husbandry, and swift urbanization heightens its susceptibility. Climate change disrupts ecosystems and animal habitats, intensifying human-wildlife interactions. Urbanization, inadequate sanitation, and insufficient healthcare infrastructure further facilitate disease spread. Climate-induced displacement adds another layer of complexity. Mitigation strategies include improving surveillance systems, fostering early detection via point-of-care diagnostics and digital contact tracing, and investing in vaccines and therapeutics. Our purpose of this is to advocate for sustainable land use, robust community-level public health systems, international cooperation, and resource-sharing. We also emphasize the need for effective vector-control policies, dedicated research funding, and annual awareness, vaccination, and early detection campaigns in endemic regions.

Climate Change and Medical Mycology.

Infectious disease clinics of North America pii:S0891-5520(24)00077-1 [Epub ahead of print].

This review explores how climate change influences fungal disease dynamics, focusing on emergence of new fungal pathogens, increased antifungal resistance, expanding geographic ranges of fungal pathogens, and heightened host susceptibility. Rising temperatures and altered precipitation patterns enhance fungal growth and resistance mechanisms, complicating treatment efforts. Climate-driven geographic shifts are expanding the range of diseases like Valley fever, histoplasmosis, and blastomycosis. Additionally, natural disasters exacerbated by climate change increase exposure to fungal pathogens through environmental disruptions and trauma. Many of those impacts affect primarily those already disadvantaged by social determinants of health putting them at increased risk for fungal diseases.

United States Dairy Farms and Global Warming.

Journal of dairy science pii:S0022-0302(24)01382-1 [Epub ahead of print].

Several metrics have developed for combining the warming effects of various greenhouse gases (GHG). The metric used can affect the life cycle assessment and comparison of dairy production systems due to the weighting placed on long- versus short-lived gases in the atmosphere. Global warming potential with a time horizon of 100 years (GWP-100) has become the standard but metrics are also available for other time horizons. Metrics for 20-, 100- and 500-year horizons gave average farmgate emission intensities of 2.08, 0.98 and 0.50 kg CO2e/kg of fat-and-protein-corrected-milk produced for current US dairy farms. Compared with the use of GWP metrics, which represent energy absorption, use of global temperature-change potential (GTP), combined global temperature-change potential (CGTP) or global warming potential star (GWP*) reduced the warming effect of methane relative to other GHG. These metrics representing temperature change reduced the warming potential of US dairy farms by 17 to 49% compared with the use of GWP-100. The metrics used also affected the comparison of individual production systems providing different life cycle assessments of management practices. Use of GWP-100 metrics indicated that warming from GHG emissions of US dairy farms increased 11-15% between 1971 and 2020, while the use of GTP, CGTP and GWP* metrics showed little or no effect on global temperature change over the 50-year period. Use of GWP-100 metrics indicated that GHG emissions related to milk production on dairy farms represented 1.6% of all US GHG emissions in 2020 while use of other metrics ranged from 0.9 and 1.8%. Although all approaches for representing the integrated warming impact of GHG have benefits and challenges, approaches such as CGTP and GWP* that account for the rate of methane emission relative to the oxidation rate in the atmosphere provide a more process-based assessment of the long-term impact of dairy farms on global temperature and perhaps a more scientifically sound approach for assessing strategies to mitigate the warming effect of dairy farms.

The projected impacts of climate change and fishing pressure on a tropical marine food web.

Marine environmental research, 204:106909 pii:S0141-1136(24)00570-1 [Epub ahead of print].

Small-scale fisheries, especially those from developing countries, are vital for millions. Understanding the impact of environmental and human factors on fish stocks and yields and how they might change is crucial to ensure the sustainable use of aquatic resources. We developed an ecosystem model using Ecopath and Ecosim (EwE) to investigate changes in target species biomass and ecosystem attributes over 83 years (2017-2100) caused by different scenarios of fishing pressure and ocean warming in the Brazilian Northeastern continental shelf. The simulations considered three IPCC climate change scenarios (RCP2.6 [0.42 °C], RCP4.5 [1.53 °C], and RCP8.5 [4.02 °C]) and four fishing pressure scenarios: two with increased pressure (10% and 30%) and two with decreased pressure (-10% and -30%). The Ecopath model indicated that the Brazilian Northeastern continental shelf ecosystem is a grazing-based system with high biomass in macroalgae and detritus compartments, supporting a diverse community of consumers. Our simulations projected overall reductions in the biomass of target species, mainly under extreme climate change. Increasing temperatures and fishing efforts reduced the biomass of large predatory species and the food web length in several scenarios. Although projected changes in ecological network and information metrics were of lower magnitude, results predicted declines in production/respiration ratio, material cycling, and ascendency (variable related to trophic specialization, internalization, and material cycling) with climate change. These declines were likely linked to increased respiration rates, metabolic costs, and lower trophic efficiency with elevated temperatures. Together, our results show how climate change and fishing pressure can change the structure of coastal ecosystems, potentially leading to undesirable alternative states for fisheries. Our approach demonstrates the effectiveness of ecosystem-based modeling in projecting likely trajectories of change, which can be especially useful for resource management in data-limited conditions.

Climate change policies reduce air pollution and increase physical activity: Benefits, costs, inequalities, and indoor exposures.

Environment international, 195:109164 pii:S0160-4120(24)00750-5 [Epub ahead of print].

The burden of diseases attributable to air pollution is comparable to those of global health risks such as unhealthy diets and tobacco smoking, with many air pollution sources also emitting climate heating gases. In this UK study we estimated the co-benefits of Net Zero (NZ) climate policy on the health benefits of air pollution reduction, increased active travel, outdoor exposure inequalities and indoor air pollution changes. The study focused on two of the largest UK sources, road transport and building heating, with comparisons made between NZ and UK existing policy, referred to as Business as Usual (BAU). Particulate matter (PM2.5), Nitrogen Dioxide (NO2) and Ozone (O3) projections were made between 2019 and 2050, with emphasis placed upon the NZ co-benefits in 2030 and 2040. We compared the UK BAU scenarios with the Climate Change Committee's (CCC) Balanced Net Zero Pathway (BNZP) and Widespread Innovation (WI) pathway. Compared to BAU predictions, BNZP assumptions lead to more electric vehicles, reduced vehicle km, more low carbon building heating, and reduced emissions of NO2 and PM2.5. By 2040 under BNZP, relative to BAU, the buildings sector was predicted to be three times more effective at reducing PM2.5 than road transport. To help reduce the inequality gap the NZ building transition was tailored toward those most in need. Outdoor air pollution exposure inequalities prevailed across the socioeconomic spectrum, especially for NO2, but were less pronounced due in part to NZ policies. Core air quality health benefits for the BNZP buildings sector were £21.3 billion (16.4 to 26.2) by 2050 and £98.4 billion (75.7 to 121.1) by 2154. For the transport sector the health benefits were £9.1 billion (7.0 to 11.2) by 2050 and £36.5 billion (28.1 to 44.9) by 2154. NZ building sector operating costs did not achieve break-even via efficiency savings, but with Greenhouse Gas (GHG) (lower benefits) break-even was achieved in 2052. With additional air pollution health benefits, building-sector time to break-even improved by between 3.1 (2.5 to 4.7) and 6.3 (4.7 to 7.6) years to between 2046 and 2049. Analysis found that removing gas cooking at home, for NZ, may result in greater concentration reductions than outdoor air pollution for NO2. Net Zero health and economic co-benefits are large, as are the changes needed, requiring political leadership and public engagement. Our findings are relevant to other countries facing the NZ transition.

Climate change impacts of biological treatment of liquid digestate from the anaerobic digestion of food waste.

Waste management (New York, N.Y.), 193:339-349 pii:S0956-053X(24)00645-7 [Epub ahead of print].

The liquid fraction of digestate (LFD) from anaerobic digestion of food waste contains high nitrogen concentrations, and in some countries, the LFD is treated as wastewater. We modelled alternative LFD treatments, including pretreatment with the partial nitritation Anammox (PNA) process. The PNA effluent is discharged to the sewers to undergo further treatment by conventional nitrification and (post- or pre-) denitrification. Life-cycle inventories were developed for the LFD treatment alternatives, including N2O emissions and electricity consumption estimates. The climate change (CC) impact was estimated using life cycle assessment in three different energy systems ranging from fossil-based to fully renewable. In the fossil energy system, pretreatment with PNA was attractive, while in the more renewable energy systems, the PNA process did not improve the CC account due to high N2O emissions. Pre-denitrification is the most attractive LFD treatment technology in a fully renewable energy system. Linking the LFD treatment to the anaerobic digestion of food waste showed that LFD treatment is a significant contributor to the overall CC account. As we move towards less fossil-based electricity, the anaerobic digestion of food waste constitutes a CC load of 350-450 kg CO2-eq/tonne biowaste, of which up to a third can be attributed to the LFD treatment. The N2O emissions are the main contributor, constituting up to 50 % in a fossil-based energy system and even higher in a renewable energy system. We conclude that the LFD treatment must be addressed in assessing anaerobic digestion when the LFD is discharged to the sewer. Our study also points to the need to find alternative ways of managing the LFD.

The effect of climate change on economic growth in European countries: an empirical evidence from Panel ARDL approach.

Environmental science and pollution research international [Epub ahead of print].

This paper examined the impact of climate change on economic growth using panel data from 20 European countries during the period 1990-2020 and the estimation techniques of cointegration and the ARDL model. The empirical results reveal that precipitation; labour force and CO2 emissions have a positive effect on long-term economic growth in sample countries. However, temperature, foreign direct investment, and urbanization have a negative effect on growth over the same period. Therefore, our study highlights the complex links between climate, demographic, and economic developments in European countries over the past three decades. Urbanizations, as a driver of urban development, and FDI, indicators of economic attractiveness, influence not only economic dynamics but also environmental impacts, exacerbating the challenges of CO2 emissions and climate change.

Preparing for stormy weather: building VA health system resilience for dialysis emergency preparedness in the era of climate change.

Current opinion in nephrology and hypertension pii:00041552-990000000-00209 [Epub ahead of print].

PURPOSE OF REVIEW: Climate change has been implicated as the driver for the increasing number, intensity, duration, and consequences of catastrophic weather events. As a result of extreme weather events, climate change has also been implicated as an important mediator of adverse kidney health outcomes, not only increasing the risk for the development of acute and chronic kidney diseases, but also disrupting the delivery of critical kidney health services. In particular, the delivery of dialysis services during major emergencies remains an ongoing and increasing problem, with a recognized need for improved emergency preparedness and disaster management (EP-DM) strategies to mitigate the increased risk of morbidity and mortality associated with missed dialysis treatment.

RECENT FINDINGS: There are increasing reports detailing the challenges of kidney dialysis care in times of crisis, to include those resulting from both man-made and natural disasters. Optimized management of the high-risk vulnerable dialysis patient population must include both facility-facing comprehensive continuity of operations and emergency response plans, and ongoing patient-facing emergency preparedness education.

SUMMARY: This review discusses the adverse impact of climate change-related natural disasters on the delivery of dialysis services, and the evolving EP-DM strategies developed and implemented by the Veterans Health Administration (VA) to optimize the care and well being of the vulnerable end stage kidney disease (ESKD) patient population.

Simulation of Pseudostellaria heterophylla distribution in China: assessing habitat suitability and bioactive component abundance under future climate change scenariosplant components.

Frontiers in plant science, 15:1498229.

BACKGROUND: Pseudostellaria heterophylla is used in traditional Chinese medicine, so ensuring an adequate supply of plant material with high levels of bioactive components is important.

METHODS: Using an optimized maximum entropy niche model and assays of bioactive components from cultivation samples, this study started from the plant's natural distribution area and estimated correlations of ecological factors with not only abundance of the plant but also abundance of polysaccharides and heterophyllin B. These correlations were combined with the spatial analysis function in ArcGIS to generate maps of the suitability of different habitats in China for cultivating P. heterophylla under current climate conditions and different models of climate change.

RESULTS: The following ecological factors emerged as particularly important for habitat suitability: precipitation of driest month and driest quarter, annual precipitation, annual mean temperature, temperature seasonality, and mean temperature of coldest quarter, contributing to a cumulative total of 87%. Under current climate conditions, optimum habitats of P. heterophylla were mainly distributed in the southwestern region (Guizhou) and eastern regions (Anhui, Zhejiang, Fujian, Jiangsu) of China, and only 0.197×10[6] km[2] of these areas were optimum habitat. In future climate change scenarios, the optimal habitat area of P. heterophylla exhibited an increase across different time periods under the SSP5-8.5 climate scenario. By the 2090s, distribution area of high heterophyllin B content under SSP5-8.5 climate scenarios will increase significantly, distribution area of high polysaccharide content had little change under all three climate scenarios (SSP 1-2.6, 2-4.5, 5-8.5). The center of mass of suitable habitat migrates southwestward under scenario SSP 1-2.6 and SSP 2-4.5, while it migrates northward under scenario SSP 5-8.5. Under the three climate scenarios, the center of mass of suitable habitat migrated consistently with that of high polysaccharide content but differed from that of high heterophyllin B content.

CONCLUSION: These findings provide a crucial foundation for cultivating P. heterophylla with superior medicinal properties, developing adaptive management strategies to enhance conservation efforts, and ensuring sustainable utilization in the face of global climate change.

Impact of climate change on the Himalayan alpine treeline vegetation.

Heliyon, 10(23):e40797.

The Himalayan alpine treeline varies depending on altitude and aspects, supporting a variety of plant species. In recent years, climate changes have exerted pressure on the vegetation in this region, challenging its adaptation to rapidly changing environmental conditions. This systematic review commenced by formulating a research question on the impact of climate change on Himalayan alpine treeline vegetation and conducted a thorough literature search, adhering to the PRISMA protocol. The rising temperatures, altered precipitation patterns, and other climate-related factors have initiated an upward shift in the treeline that threatens the unique biodiversity of the region. Indeed, in various parts of the Himalayas, there is evidence of the treeline moving upwards, altering plant regeneration and growing season, and impacting soil properties. There is a shift of vegetation ranging from 0.80 to 503.00 m in Himalayan treeline regions have been reported in various studies. Abies spectabilis and Betula utilis are the most sensitive, showing the highest upward shifts due to climate change. The repercussions of climate change on the Himalayan alpine treeline are anticipated to have significant ecological implications. Most species at the Himalayan alpine treeline exhibit poor regeneration status, while some others reveals good, fair, or no regeneration. Consequently, new regeneration patterns are emerging. Changes in soil temperature and physicochemical properties due to climate warming are ultimately affecting Himalayan alpine treeline vegetation. Additionally, shifts in the growing season and phenophases of various tree species have also been observed. The profound and far-reaching impacts of climate change on the Himalayan alpine treeline necessitates implementing mitigation and adaptation strategies to safeguard the delicate alpine ecosystems of the region.

Health impacts of climate change in the UK: A qualitative synthesis detailing the conjuncture of social structure, extreme weather, and mental health.

SSM. Qualitative research in health, 6:100475.

This qualitative synthesis explores the experiences of UK communities facing growing health risks from climate change and extreme weather. The eight included studies show the profound impacts of extreme weather events such as floods on mental health, including challenges to self-identity and anxiety from the fear of flooding returning. Included data reveal individual and household impacts of extreme weather are mediated by a complex interaction of institutional support, community support, gender inequalities and personal agency. These factors are assessed against the backdrop of broader concepts in the social science and adaptation literature, including the role of the state, the inseparability of nature and society, the overlooked role of social structure, and environmental justice. It is argued that the use of qualitative synthesis methods in this topic area allows for an interconnected and context-sensitive analysis of the health impacts of climate change facing communities, diverging from other analytical approaches through inclusion of considerations such as social power, community dynamics, and the inter-relation of institutional action, community cohesion and individual agency. The resulting findings show how locally specific and highly contextual qualitative data can be used by those seeking to understand health risks from climate change within a locality.

Winners and Losers From Climate Change: An Analysis of Climate Thresholds for Tree Growth and Survival for Roughly 150 Species Across the Contiguous United States.

Global change biology, 30(12):e17597.

Changes in temperature and precipitation are already influencing US forests and that will continue in the future even as we mitigate climate change. Using spatiotemporally matched data for mean annual temperature (MAT) and mean annual precipitation (MAP), we used simulated annealing to estimate critical thresholds for changes in the growth and survival of roughly 150 tree species (153 spp. for growth, 159 spp. for survival) across the conterminous United States (CONUS). We found that growth of nearly one-third of tree species assessed (44 spp.) decreased with any increase in MAT (42-49 species), whereas fewer responded negatively to projected regional trends in MAP (< 20 species each in the east and west). Hypothetical increases in temperature (+1°C, +2°C) increased average annual growth in the Central East and Pacific Northwest and decreased growth over large areas of the Rockies and Southeast, while decadal survival generally decreased with temperature. Average annual growth and decadal survival had unfavorable associations with projected precipitation, generally decreasing with wetter conditions (+25%) in the east and decreasing with drier conditions (-25%) in the west. Beyond these averages, there were species that positively and negatively responded nearly everywhere across the CONUS, suggesting changes in forest composition are underway. We identified only eight species out of ~150 assessed that were tolerant to increases in temperature, and 24 species in the east and seven in the west were tolerant to regionally specific trends in precipitation (increases in the east and decreases in the west). We assessed confidence on a 5-point scale (1-5) for five aspects of uncertainty. Average confidence scores were generally high, though some species and metrics had low confidence scores especially for survival. These findings have significant implications for the future national forest carbon sink and for conservation efforts in the face of climate change.

Detecting and classifying eco-anxiety: development of clinical cut-off scores for the climate change anxiety scale.

BMC psychology, 12(1):738.

BACKGROUND: Climate change anxiety, that is worry and fear in relation to the awareness of the impacts of climate change, is widely observed around the world. Some evidence suggests that while climate change anxiety can, at times, be adaptive, a growing body of research has reported that climate change anxiety is also related to a range of negative mental health outcomes and psychological distress. Currently, however, there is limited ability to assess for elevated levels of climate change anxiety and to identify those who may need support. The present study, therefore, aimed to develop clinical cut-off scores on a measure of climate change anxiety.

METHODS: A largely representative sample of Australian young adults (aged 16-25 years) completed measures of psychological distress (Depression, Anxiety and Stress Scale-21) and the Climate Change Anxiety Scale. Markers of clinically meaningful psychological distress - elevated depression, anxiety, and stress symptoms-were used to classify cases. Receiver Operating Characteristics analyses were performed to assess the predictive ability of the indicators of psychological distress (mild, moderate, severe, and extremely severe thresholds of anxiety, depression, and stress symptoms) for detecting climate change anxiety and to ascertain optimal cut-off scores.

RESULTS: The Area Under the Curve was acceptable to moderate for detecting climate change anxiety across all analyses. Across symptom severity thresholds and markers of psychological distress, based on consideration of balancing sensitivity and specificity, results consistently suggested that a cut-score of 21 was indicative of mild-moderate climate change anxiety, with a cut-off score of 23 indicating severe-extremely severe climate change anxiety.

CONCLUSIONS: The proposed cut-offs can feasibly be used to identify those with elevated climate change anxiety. Use of these cut-off scores can inform research as well as be used to guide screening, assessment, and inform clinical practice. Results also highlight a high rate of climate change anxiety in young adults.

Association between climate change and patient health outcomes: a mixed-methods systematic review.

BMC nursing, 23(1):900.

INTRODUCTION: Climate change poses significant threats to the environment, biodiversity, and socioeconomic stability worldwide. Its impact on human health, particularly within healthcare systems, is growing in concern. Nurses, as front-line healthcare workers, play a crucial role in addressing climate-related health risks. However, there is a gap in understanding nursing perspectives on climate change and its implications for patient health outcomes.

AIM: To synthesize empirical evidence on the association between climate change and patient health outcomes from a nursing perspective.

METHODS: A mixed-methods systematic review was conducted following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA). The search was carried out in January 2024 in six scientific databases including CINAHL, PubMed, Scopus, ProQuest, Web of Science, and OVID Nursing. Studies focusing on climate change and patient health outcomes from a nursing perspective were included. Data extraction, quality appraisal, and synthesis were performed systematically.

RESULTS: The systematic review included 18 studies of a mainly quantitative nature. Three main themes emerged as follows: Climate Healthcare Interplay; Future Nurses as Agents of Change; and Navigating Sustainability Challenges in Nursing. These themes highlighted nurses' awareness of the interrelation between climate and health, the need for environmental education in nursing, and the challenges that hinder sustainable nursing practices.

CONCLUSION: This review underscores the importance of integrating climate change topics into nursing education and fostering organizational support for sustainable nursing practices. Addressing these challenges is essential for nurses to mitigate the health risks posed by climate change effectively.

Coming to terms with climate change: a glossary for climate change impacts on mental health and well-being.

Journal of epidemiology and community health pii:jech-2024-222716 [Epub ahead of print].

Climate change is a major threat to global health. Its effects on physical health are increasingly recognised, but mental health impacts have received less attention. The mental health effects of climate change can be direct (resulting from personal exposure to acute and chronic climatic changes), indirect (via the impact on various socioeconomic, political and environmental determinants of mental health) and overarching (via knowledge, education and awareness of climate change). These impacts are unequally distributed according to long-standing structural inequities which are exacerbated by climate change. We outline key concepts and pathways through which climate change may affect mental health and explore the responses to climate change at different levels, from emotions to politics, to highlight the need for multilevel action. We provide a broad reference to help guide researchers, practitioners and policy-makers in the use and understanding of different terms in this rapidly growing interdisciplinary field.

Modeling of periodic input Ornstein-Uhlenbeck temperature-tick-borne disease transmission coupling mechanism under climate change.

Acta tropica, 261:107490 pii:S0001-706X(24)00371-1 [Epub ahead of print].

Given the rapid increase in climate change, investigating the impact of climate change on the transmission mechanism of tick-borne diseases is imperative. In order to fully capture the influence of the seasonal variation of temperature, environmental disturbances and the co-feeding transmission on the spread of tick-borne diseases, we propose a novel stochastic dynamical model that couples the mean-reverting Ornstein-Uhlenbeck temperature equation with periodic input to the tick-borne disease model. Through theoretical analysis, we derive sufficient conditions for the extinction of tick populations and the eradication of tick-borne diseases, as well as the stochastic persistence conditions of the system. In numerical simulations, we find that the periodic Ornstein-Uhlenbeck temperature equation can effectively fit the actual temperature data in low, medium, and high latitude regions of China. In risk assessment, we find that at the spatial perspective, low-latitude areas have a higher risk of tick-borne diseases, requiring enhanced control measures; from a temporal perspective, compared to the past, the current stage presents a greater risk of tick-borne diseases when preventive measures are not implemented. Additionally, we observe that larger noise of environment for tick populations favors the extinction of tick populations, while smaller temperature fluctuations, noise on infected hosts and ticks, as well as higher temperature regression rate, are more likely to lead to the extinction of tick-borne diseases. These findings provide crucial insights into understanding the impact of climate change on the transmission mechanism of tick-borne diseases.

Climate change perceptions among nursing students: A comparative study between Finland and the United States.

Nurse education today, 146:106541 pii:S0260-6917(24)00451-9 [Epub ahead of print].

INTRODUCTION: Nurses play a key role in combating climate change-related health risks by promoting adaptation and mitigation strategies. Their efforts are essential in educating patients and communities about the health impacts of climate change and sustainable healthcare practices. Nursing curricula are evolving to include climate change and sustainability. The goal is to prepare future nurses to effectively address climate change factors affecting health and to support the transition towards more sustainable healthcare systems.

AIM: To study the perceptions of nursing students in Finland and the United States (U.S.) regarding climate change, focusing on their awareness and attitudes.

DESIGN: A quantitative, cross-sectional study.

METHOD: In this study climate change awareness, concern, motivation, and behavior patterns of Finnish and U.S nursing students were surveyed and analyzed. Data were collected from an online survey using the Climate Health and Nursing Tool (CHANT). The data were collected from Finnish students (n = 351) from February to June 2023 and for comparison we examined data collected from U.S. (n = 352) in 2022. Data were analyzed using SPSS and AMOS program.

RESULTS: U.S. nursing students were found to have higher factor loadings, indicating a stronger connection between the measured factors and their related concepts compared to Finnish nursing students. Finnish students also received good factor loadings, but differences appeared in the correlations between awareness, concern, and motivation, and in the consistency of behavior at home and at work.

CONCLUSIONS: Findings from study indicate that U.S. students have higher overall awareness but weaker links between awareness and workplace behavior, whereas Finnish nursing students show more consistent behavior both personally and professionally. Nursing faculty could use this knowledge to engage nursing students in learning about the impact of climate change on human health and prepare future nurses to meet challenges of climate change on patient populations.

Leveraging Agri-advocacy to promote animal genetic diversity for climate change mitigation: Kenya and Tanzania perspective.

Heliyon, 10(23):e40851 pii:S2405-8440(24)16882-X.

The role that genetic diversity in animal genetic resources (AnGR) plays in mitigating the effects of climate change on the global protein supply is of the utmost significance. East Africa historically played a pivotal role in the dispersal of domesticated livestock species across the African continent. At present, it maintains a substantial contribution to worldwide biodiversity as a result of its reservoir of a diverse array of AnGR, characterized by genetic and species diversity. A considerable reduction in the genetic diversity of AnGR has been documented in numerous studies, giving rise to concerns regarding the sustainability of animal protein supply in the face of climate change. The objective of this article is to outline prospective roles that advocacy and management organizations specializing in AnGRs may undertake to aid in the conservation of AnGR genetic diversity in East Africa. Moreover, it provides a prospective framework and structure for advocacy that extends from the farmers, to the higher-level (regional farmers association). We believe that advocating for the promotion of genetic diversity at the regional level will have a significant impact at the national and further at global scale.

Tree drought physiology: critical research questions and strategies for mitigating climate change effects on forests.

The New phytologist [Epub ahead of print].

Droughts of increasing severity and frequency are a primary cause of forest mortality associated with climate change. Yet, fundamental knowledge gaps regarding the complex physiology of trees limit the development of more effective management strategies to mitigate drought effects on forests. Here, we highlight some of the basic research needed to better understand tree drought physiology and how new technologies and interdisciplinary approaches can be used to address them. Our discussion focuses on how trees change wood development to mitigate water stress, hormonal responses to drought, genetic variation underlying adaptive drought phenotypes, how trees 'remember' prior stress exposure, and how symbiotic soil microbes affect drought response. Next, we identify opportunities for using research findings to enhance or develop new strategies for managing drought effects on forests, ranging from matching genotypes to environments, to enhancing seedling resilience through nursery treatments, to landscape-scale monitoring and predictions. We conclude with a discussion of the need for co-producing research with land managers and extending research to forests in critical ecological regions beyond the temperate zone.

Climate change impacts of municipal water sector and mitigation pathways: A national scale analysis and perspectives to carbon neutrality.

Journal of environmental management, 373:123732 pii:S0301-4797(24)03718-6 [Epub ahead of print].

The growing concern on global warming has pushed to set ambitious targets of carbon neutrality or net zero at the water sector. Meanwhile, poor data availability has been reported to restrict the national assessment of climate impacts and mitigation strategies in water sector. In national greenhouse gas (GHG) inventories, water sector is embedded in other sectors' emissions making it difficult to monitor separately. This study presents a national scale evaluation of climate change impacts for water sector in Finland based on life cycle analysis (LCA). In addition, the effectiveness of currently available emission reduction measures is evaluated by scenario analysis until the year 2035. According to the results, the life cycle climate change impacts from the Finnish municipal water sector were 0,67 (0,46-0,88) million tonnes CO2-eq./year (142.8 (98.9-187.1) kg CO2-eq./person/year). Drinking water services accounted for 12.5-13.9 % and wastewater services 86.1-87.4 % of the total emissions. With currently feasible emission reduction measures, the climate change impacts could be reduced approximately 14-30 % in total by 2035. The aim of carbon neutrality in the water sector was found to be unrealistic to achieve with existing and currently feasible measures for Finland and thus significant new emission mitigation measures are needed. The vague definition of carbon neutrality and system boundary of water sector as well as the uncertainties related to the assessment of direct emissions, undermine the credibility of the ambitiously set target. Prioritizing emission offsets to reach the target may inadvertently lead to unintended negative consequences due to the limitations and incompleteness of offset methods.

Global distribution pattern and conservation of the cosmopolitan cold-water coral species Desmophyllum dianthus under climate change.

Journal of environmental management, 373:123674 pii:S0301-4797(24)03660-0 [Epub ahead of print].

Global climate change impacts marine ecosystems differently across oceanic regions and depths. Thus, understanding how widespread key species adapt globally and locally to multidimensional climate change is crucial for targeted conservation. This study focuses on the cosmopolitan cold-water coral (CWC) Desmophyllum dianthus using ecological niche models (ENMs) to explore climate adaptation and conservation strategies. The findings indicated that D. dianthus occupied a broad ecological niche but had low ecological niche overlap across populations, suggesting local adaptations and supporting population-level ENMs. The models predicted that over 80% of D. dianthus suitable habitats would persist under SSP1-2.6 and SSP5-8.5 climate scenarios by the 2100s, potentially increasing to 95% as new habitats emerge, demonstrating its robust adaptability. However, localized environmental shifts could precipitate habitat losses in areas like the Reykjanes Ridge, Rockall Plateau, Mediterranean Sea, and Patagonian Shelf. We also applied Linkage Mapper to identify potential ecological corridors that intertwined nearshore macrohabitat patches with deep-sea stepping-stone habitats such as escarpments, seamounts, and ridges, maintaining population connectivity. Despite this, the habitats and ecological corridors of D. dianthus remained largely unprotected, with vulnerable portions lying outside of marine protected areas (MPAs), thus underscoring the urgent need for more MPA. These spatial-temporal predictions provide essential insights for the conservation and management of cosmopolitan CWC D. dianthus and serve as a benchmark for the adaptive survival of similar taxa.

Simulated winter climate change reveals greater cold than warm temperature tolerance in Chrysolina polita (Coleoptera: Chrysomelidae).

Environmental entomology pii:7926937 [Epub ahead of print].

Climate change is expected to lead to rising winter temperatures in temperate zones, coinciding with a decrease in winter snow cover. Insects adapted to winter conditions in the temperate zone might be exposed to changing winter conditions and higher temperature fluctuations, which can affect diapause and mortality. We studied the effects of climate change on Chrysolina polita, a temperate zone species overwintering as an adult in the shallow surface of the soil. We tested the effects of increased and fluctuating temperature on the mortality and body composition of the beetles in a laboratory environment, as well as the effects of snow cover removal on the mortality and body mass in field conditions. We found that in the laboratory study, a 2 °C increase in mean temperature increased mortality and resulted in increased lipid consumption, whereas temperature fluctuation caused desiccation of the beetles but did not affect mortality compared to the control condition. In the field study, the snow removal caused the mean soil temperature to decrease by 3 °C and fluctuate (ranging from -26.4 to 2.5 °C compared to a range of -1.7 to 0.5 °C in the control), yet these differences did not affect beetle mortality or body mass. We conclude that C. polita exhibits greater resistance to cold temperatures than to higher temperatures during diapause. Therefore, the rising temperatures associated with climate change can pose challenges for overwintering.

Connecting the ruminant microbiome to climate change: insights from current ecological and evolutionary concepts.

Frontiers in microbiology, 15:1503315.

Ruminant livestock provide meat, milk, wool, and other products required for human subsistence. Within the digestive tract of ruminant animals, the rumen houses a complex and diverse microbial ecosystem. These microbes generate many of the nutrients that are needed by the host animal for maintenance and production. However, enteric methane (CH4) is also produced during the final stage of anaerobic digestion. Growing public concern for global climate change has driven the agriculture sector to enhance its investigation into CH4 mitigation. Many CH4 mitigation methods have been explored, with varying outcomes. With the advent of new sequencing technologies, the host-microbe interactions that mediate fermentation processes have been examined to enhance ruminant enteric CH4 mitigation strategies. In this review, we describe current knowledge of the factors driving ruminant microbial assembly, how this relates to functionality, and how CH4 mitigation approaches influence ecological and evolutionary gradients. Through the current literature, we elucidated that many ecological and evolutionary properties are working in tandem in the assembly of ruminant microbes and in the functionality of these microbes in methanogenesis. Additionally, we provide a conceptual framework for future research wherein ecological and evolutionary dynamics account for CH4 mitigation in ruminant microbial composition. Thus, preparation of future research should incorporate this framework to address the roles ecology and evolution have in anthropogenic climate change.

Winter climate change mediates the sensitivity of vegetation leaf-out to spring warming in high latitudes in China.

Frontiers in plant science, 15:1476576.

Global warming has significantly altered plant phenology by advancing the timing of leaf emergence, impacting vegetation productivity and adaptability. Winter and spring temperatures have commonly been used to explain spring phenology shifts, but we still lack a solid understanding of the effects of interactions between conditions in different seasons. This study utilizes normalized difference vegetation index (NDVI) and meteorological data to examine the effects of changes in winter and spring temperatures and precipitation on the start of the vegetation growing season (SOS) at high latitudes in China from 1982 to 2015. We found that SOS in Northeast China, as a whole, showed a weak advancing trend (moving earlier in the year), but with obvious regional differences. Even within the same vegetation type, changes in SOS were faster in the cold north (1.9 days/decade) and the cold and dry northwest (1.6 days/decade) than the regional averages for deciduous needleleaf forests (DNF; 1.2 days/decade) and grasslands (0.6 days/decade). Increases in spring temperatures dominate forest SOS advancement, while grassland SOS is mainly influenced by winter and spring precipitation. Decreases in winter minimum temperature (Tmin) enhance the spring temperature sensitivity of SOS. The way that winter precipitation regulates the spring temperature sensitivity of SOS differs among vegetation types: increasing sensitivity in grasslands but suppressing it in DNF. The moderating effects of winter conditions account for the greatest part of the regional differences in the magnitude of change in SOS. Our findings highlight that, although rising spring temperatures significantly affect SOS, winter Tmin and precipitation are crucial for understanding spatial SOS differences, particularly in cold, arid high-latitude regions. Winter conditions play an essential role in regulating the response of vegetation SOS to spring climate at high latitudes. These results suggest that considering the moderating effect of winter climate can facilitate more accurate predictions of temperature-driven phenological changes under future climate change.

Geographical Distribution Dynamics of Acorus calamus in China Under Climate Change.

Plants (Basel, Switzerland), 13(23):.

Acorus calamus, a perennial emergent herb, is highly valued for its ornamental appeal, water purification ability, and medicinal properties. However, there is a significant contradiction between the rapidly increasing demand for A. calamus and the diminishing wild resources. Understanding its geographical distribution and the influence of global climate change on its geographical distribution is imperative for establishing a theoretical framework for the conservation of natural resources and the expansion of its cultivation. In this study, 266 distribution records of A. calamus and 18 selected key environmental factors were utilized to construct an optimal MaxEnt model via the ENMeval package. We simulated the potential geographical distributions under current conditions and under three different climate scenarios (SSP126, SSP370, and SSP585) in the 2050s, 2070s, and 2090s. Additionally, we employed the jackknife method and response curves to identify the environmental factors with the greatest influence on the distribution of A. calamus, and their response intervals. The results indicate that the regularization multiplier (RM) of 3.5 and the feature combinations (FC) of linear (L), quadratic (Q), hinge (H), and product (P) are the optimal model parameter combinations. With these parameters, the model predictions are highly accurate, and the consistency of the results is significant. The dominant environmental factors and their thresholds affecting the distribution of A. calamus are the precipitation of the wettest month (≥109.87 mm), human footprint (≥5.39), annual precipitation (≥388.56 mm), and mean diurnal range (≤12.83 °C). The primary land use types include rivers and channels, reservoirs and ponds, lakes, urban areas, marshes, other constructed lands, rice fields, forested areas, and shrublands. Under current climate conditions, the suitable geographical distribution of A. calamus in China is clearly located east of the 400 mm precipitation line, with high- and low-suitability areas covering 121.12 × 10[4] km[2], and 164.20 × 10[4] km[2], respectively. Under future climate conditions, both high- and low- suitability areas are projected to increase significantly, whereas unsuitable areas are expected to decrease, with the centroid of each suitability zone shifting northward. This study provides a theoretical foundation for sustainable utilization, future production planning, and the development of conservation strategies for wild germplasm resources of A. calamus.

Modeling the Distribution of the Rare and Red-Listed Halophytic Moss Species Entosthodon hungaricus Under Various Climate Change Scenarios in Serbia.

Plants (Basel, Switzerland), 13(23):.

Entosthodon hungaricus is a rare moss species of the salty grasslands in Serbia. It is threatened with extinction due to habitat destruction and loss, although it reproduces sexually. In this study, we tested different models predicting its distribution under several climate scenarios over the next 8 decades. All models tested indicated a reduction in range to varying extents. Due to the specific substrate type as well as the predicted loss owing to the climate change, shifting is not an option for the survival of this species; and, therefore, it deserves special attention for its conservation and management.

Cytoplasm of the Wild Species Aegilops mutica Reduces VRN1 Gene Expression in Early Growth of Cultivated Wheat: Prospects for Using Alloplasmic Lines to Breed Varieties Adapted to Global Warming.

Plants (Basel, Switzerland), 13(23):.

In a warm winter due to climate warming, it is necessary to suppress early flowering of autumn-sown wheat plants. Here, we propose the use of cytoplasmic genome effects for this purpose. Alloplasmic lines, or cytoplasmic substitution lines, of bread wheat (Triticum aestivum) have cytoplasm from a related wild Aegilops species through recurrent backcrossing and exhibit altered characteristics compared with the euplasmic lines from which they are derived. Thus, alloplasmic lines with Aegilops mutica cytoplasm show delayed flowering compared with lines carrying normal cytoplasm. In the wheat flowering pathway, VERNALIZATION 1 (VRN1) encodes an APETALA1/FRUITFULL-like MADS box transcription factor that plays a central role in the activation of florigen genes, which induce floral meristems in the shoot apex. Here, we compared expression of VRN1 alleles in alloplasmic and euplasmic lines after vernalization. We found that alloplasmic wheat showed a lower level of VRN1 expression after vernalization compared with euplasmic wheat. Thus, nuclear-cytoplasm interactions affect the expression levels of the nuclear VRN1 gene; these interactions might occur through the pathway termed retrograde signaling. In warm winters, autumn-sown wheat cultivars with spring habit can pass through the reproductive growth phase in very early spring, resulting in a decreased tiller/ear number and reduced yield performance. Here, we present data showing that an alloplasmic line of 'Fukusayaka' can avoid the decrease in tiller/ear numbers during warm winters, suggesting that this alloplasmic line may be useful for development of varieties adapted to global warming.

Spatio-Temporal Heterogeneity of Ecological Quality in a Typical Dryland of Northern China Driven by Climate Change and Human Activities.

Plants (Basel, Switzerland), 13(23):.

With the intensification of climate change and anthropogenic impacts, the ecological environment in drylands faces serious challenges, underscoring the necessity for regionally adapted ecological quality evaluation. This study evaluates the suitability of the original Remote Sensing Ecological Index (oRSEI), modified RSEI (mRSEI), and adapted RSEI (aRSEI) in a typical dryland region of northern China. Spatio-temporal changes in ecological quality from 2000 to 2022 were analyzed using Theil-Sen median trend analysis, the Mann-Kendall test, and the Hurst exponent. Multiple regression residual analysis quantified the relative contributions of climate change and human activities to ecological quality changes. Results showed that (1) the aRSEI was the most suitable index for the study area; (2) observed changes exhibited significant spatial heterogeneity, with improvements generally in the inner areas of the Yellow River and declines in the outer areas; and (3) changes in ecological quality were primarily driven by climate change and human activities, with human activities dominating from 2000 to 2011 and the influence of climate change increasing from 2012 to 2022. This study compares the efficacy of RSEIs in evaluating dryland ecological quality, identifies spatio-temporal change patterns, and elucidates driving mechanisms, offering scientific evidence and policy recommendations for targeted conservation and restoration measures to address future changes in dryland regions.

Climate change and Vibrio vulnificus dynamics: A blueprint for infectious diseases.

PLoS pathogens, 20(12):e1012767.

Climate change is having increasingly profound effects on human health, notably those associated with the occurrence, distribution, and transmission of infectious diseases. The number of disparate ecological parameters and pathogens affected by climate change are vast and expansive. Disentangling the complex relationship between these variables is critical for the development of effective countermeasures against its effects. The pathogen Vibrio vulnificus, a naturally occurring aquatic bacterium that causes fulminant septicemia, represents a quintessential climate-sensitive organism. In this review, we use V. vulnificus as a model organism to elucidate the intricate network of interactions between climatic factors and pathogens, with the objective of identifying common patterns by which climate change is affecting their disease burden. Recent findings indicate that in regions native to V. vulnificus or related pathogens, climate-driven natural disasters are the chief contributors to their disease outbreaks. Concurrently, climate change is increasing the environmental suitability of areas non-endemic to their diseases, promoting a surge in their natural populations and transmission dynamics, thus elevating the risk of new outbreaks. We highlight potential risk factors and climatic drivers aggravating the threat of V. vulnificus transmission under both scenarios and propose potential measures for mitigating its impact. By defining the mechanisms by which climate change influences V. vulnificus disease burden, we aim to shed light on the transmission dynamics of related disease-causing agents, thereby laying the groundwork for early warning systems and broadly applicable control measures.

Spatiotemporal dynamics of grassland aboveground biomass in northern China and the alpine region: Impacts of climate change and human activities.

PloS one, 19(12):e0315329.

Grassland plays a crucial role in the global cycles of matter, energy, water and, climate regulation. Biomass serves as one of the fundamental indicators for evaluating the ecological status of grassland. This study utilized the Carnegie-Ames-Stanford Approach (CASA) model to estimate Net Primary Productivity (NPP) from meteorological data and the Global Inventory Monitoring and Modeling System (GIMMS) Normalized Difference Vegetation Index (NDVI) remote sensing data for northern China's temperate and alpine grasslands from 1981 to 2015. NPP was subsequently converted into aboveground biomass (AGB). The dynamic changes in grassland AGB were analyzed, and the influence of climate change was examined. The results indicate strong agreement between AGB estimations from the CASA model and Gill method based on field-measured AGB, confirming the model's reliability for these regions. The dynamic changes in AGB exhibited a significant increasing trend of 1.31 g/m2. Grazing intensity (GI), soil moisture, and mean annual precipitation are identified as key factors influencing changes in grassland AGB. Our findings indicate that precipitation and soil moisture are the primary drivers of AGB accumulation during the growing season (spring, summer, and autumn), while temperature plays a critical role in supporting biomass accumulation during winter. Higher temperatures in winter contributes to increased AGB in the following spring, particularly in desert steppe and alpine meadow ecosystems. These insights highlight the complex interaction between climate factors and human activities in shaping grassland productivity across different seasons.

A Systematic Review on the Outcomes of Climate Change in the Middle-Eastern Countries: The Catastrophes of Yemen and Syria.

Environmental health insights, 18:11786302241302270.

The Middle East is facing serious climate change challenges, rendering it as one of the most affected regions worldwide. This paper aimed to investigate the outcomes of climate change in the Middle East. In 2024, a qualitative study was conducted employing a methodology that integrated systematic review for data collection and thematic analysis for data analysis. Such integration of the approaches provided valuable insights into the findings within the literature in a comprehensive and categorized format. PubMed, Scopus, ProQuest, and the Cochrane Database of Systematic Reviews were searched for relevant studies published between 2000 and 2024. The quality of these studies was assessed using the AACODS (Accuracy, Coverage, Objectivity, Date, Significance) checklist. The data extracted from the included studies underwent a thematic analysis utilizing Braun and Clarke's methodology. After completing the screening process, a total of 93 papers were deemed suitable for inclusion in the study. The quality assessment of these selected studies demonstrated a notably high standard, particularly in terms of authority, accuracy, coverage, objectivity, and significance. Moreover, minimal levels of bias were observed within the included studies. Subsequent thematic analysis of the findings from the systematic review identified 6 overarching themes: "Human Health Outcomes," "Animal Health Outcomes," "Plant Health Outcomes," "Ecological Outcomes," "Economic Outcomes," and "Political Outcomes." The study revealed ecological outcomes as the most prevalent consequences of climate change in the Middle East, including alterations in habitat distribution, temperature increase, water scarcity, and more. The outcomes seemed to be interconnected, exacerbating each other. Yemen and Syria had faced severe consequences, leading to political unrest and humanitarian crises in which Yemen ranking among the most water-stressed nations globally, while Syria contending with millions of displaced individuals living in dire conditions.

Accounting for Pacific climate variability increases projected global warming.

Nature climate change, 14(6):608-614.

Observational constraint methods based on the relationship between the past global warming trend and projected warming across climate models were used to reduce uncertainties in projected warming by the Intergovernmental Panel on Climate Change. Internal climate variability in the eastern tropical Pacific associated with the so-called pattern effect weakens this relationship and has reduced the observed warming trend over recent decades. Here we show that regressing out this variability before applying the observed global mean warming trend as a constraint results in higher and narrower twenty-first century warming ranges than other methods. Whereas the Intergovernmental Panel on Climate Change assessed that warming is unlikely to exceed 2 °C under a low-emissions scenario, our results indicate that warming is likely to exceed 2 °C under the same scenario, and hence, limiting global warming to well below 2 °C will be harder than previously anticipated. However, the reduced uncertainties in these projections could benefit adaptation planning.

Implementing and Assessing Climate Change Education in a Pediatrics Residency Curriculum.

Journal of graduate medical education, 16(6 Suppl):92-98.

Background For physicians to effectively combat the growing health crisis that is climate change, they should begin learning during medical training about its health implications. However, there is little data on residents' knowledge of the climate crisis, and even less data regarding the effectiveness and acceptability of climate change education in graduate medical training programs. Objective To incorporate a new educational session on the health implications of climate change into a residency curriculum and evaluate the acceptability of the session and its effects on residents' knowledge, attitudes, and perceptions of the topic. Methods In July 2021, a 90-minute, interactive, small-group format educational session on the health implications of climate change was incorporated into the first-year curriculum of a pediatric residency program. From July 2021 through June 2023, resident participants completed pre- and post-session surveys that assessed their knowledge, attitudes, and perceptions regarding health implications of climate change. Likert scale data were analyzed using Wilcoxon signed-rank tests. Results Of the 109 residents scheduled to participate, 50 (46%) completed both the pre- and post-session surveys. Session participation increased residents' self-reported knowledge of how climate change impacts health and how physicians can act as climate advocates. Ninety-eight percent of all post-session respondents (58 of 59) agreed that they would recommend the session to other residents. With 3 facilitators, the monthly session required ≤4 hours of preparation and ≤12 hours of direct teaching time per facilitator each academic year. Conclusions A single educational session improved residents' self-reported knowledge of the health implications of climate change and was well-received by participants.

Background Physicians require climate-related training, but not enough is known about actual or desired training at the graduate medical education level. Objective To quantify the climate curriculum provided within a network of family medicine residency programs in the Northwestern United States, to assess barriers to adoption of climate curricula, and to identify preferred climate-related content, delivery methods, and program actions. Methods In fall 2021, residents and faculty in a family medicine residency network responded to a 25-item, anonymous, online survey about climate-related training within their programs. Likert scales were used to assess the extent of current and desired climate curricula in respondent programs, and a paired samples t test was used to compare them. Drop-down menus and frequencies were used to identify top barriers to integration of a climate curriculum, and preferred curricular content, delivery methods, and program actions. Results Responses were received from 19.3% (246 of 1275) of potential respondents. Nearly ninety percent (215 of 240) reported little or no climate content in their programs. Respondents desired significantly more climate-related training (t[237]=18.17; P<.001; Cohen's d=1.18) but identified several barriers, including insufficient time/competing curricular priorities (80.7%, 192 of 238), concern about the political/controversial nature of the topic (27.3%, 65 of 238), and perceived irrelevance (10.9%, 26 of 238). More respondents selected integration of climate content throughout relevant didactics (62.2%, 145 of 233) than other delivery methods. Over 42% of respondents selected each of the climate-related topics and program actions suggested. Conclusions Despite a number of barriers, most family medicine faculty and residents desire significantly more climate-related content in their training curricula.

Climate Change Curricula in US Graduate Medical Education: A Scoping Review.

Journal of graduate medical education, 16(6 Suppl):69-77.

Background Climate change threatens humanity's health and well-being. While climate change topics have been increasingly incorporated into undergraduate medical education, it is unclear to what extent they have been incorporated into graduate medical education (GME) curricula in the United States. Objective To examine how climate change has been incorporated into GME curricula in the United States. Methods We conducted a scoping review of published literature from January 2013 through November 2023. PubMed and Scopus were searched, with articles assessed by 3 reviewers in a blinded fashion. Resources were included if they described how climate change is incorporated into GME curricula in the United States, and if they discussed topics such as disaster medicine, mass casualty events, environmental medicine, public health, health policy, wilderness medicine, quality improvement, and sustainability. Articles were analyzed using descriptive numerical analysis and qualitative assessment to identify article characteristics and themes. Results The inclusion criteria generated 17 articles that examined climate change incorporation into GME curricula and curriculum interventions covering topics used for inclusion. The most common type of article (5 of 17, 29%) employed surveys of program directors on the inclusion of climate-related topics. Conclusions Published accounts of climate-related topics in US GME program curricula are few. More content is found in topics related to emergency medicine. Curricula frameworks have been proposed for pediatric and internal medicine residency programs, but we know little about their efficacy. Future scholarship should fill these gaps to educate learners to improve health care sustainability and resiliency.

Development and Implementation of a Climate Change and Health Curriculum Into Pediatric Residency Education.

Journal of graduate medical education, 16(6 Suppl):125-128.

Background There is an increasing body of evidence demonstrating the impacts of climate change on health. Physicians recognize the significance but feel unprepared to address it. Despite a call to action from prominent medical organizations, climate change and health (CCH) education has remained sparse. Objective To describe the development and feasibility of a formal climate change curriculum tailored to pediatric residency programs and to assess residents' pre-intervention knowledge and self-reported comfort with this topic. Methods We created a longitudinal, single-institution CCH curriculum for pediatric and combined internal medicine-pediatrics residents. Implementation and evaluation began in May 2023 and is ongoing. Several educational strategies are utilized, and assessment tools include knowledge- and attitudes-based assessments, case-based exercises, reflective writing, grading rubrics, and patient encounter assessments. Feasibility was tracked. Results Sixty-one residents were eligible for participation at the beginning of the study. Pre-intervention knowledge-based assessments were completed by 14 of the 61 residents (23.0%), and attitude-based questions were completed by 12 residents (19.7%). Baseline knowledge assessment showed varied proficiency in CCH topics, and attitudes data showed that while most respondents felt CCH education was important (11 of 12, 91.7%), no respondents felt "very comfortable" discussing these topics with patients. In the first year of the curriculum, after residents applied knowledge in a small-group, case-based exercise, most groups were graded as "not yet competent" in all categories utilizing a rubric. Conclusions This study demonstrates that a CCH curriculum can be feasibly designed and implemented.

A Graduate Medical Education Fellowship in Climate Change and Human Health: Experience and Outcomes From the First 5 Years.

Journal of graduate medical education, 16(6 Suppl):129-134.

Background Climate change is affecting health and health care, but most physicians lack formal training on climate change. There is a need for graduate medical education (GME) programs that prepare physician leaders to address its health impacts. Objective To describe the development and iterative piloting of a GME fellowship in climate change and health and to assess fellows' academic output and public engagement before and after fellowship matriculation. Methods A GME training program was developed and implemented at an emergency medicine department in a US teaching hospital in collaboration with affiliated academic centers. Participants consisted of emergency physicians from the United States and abroad. Program duration and format were adjusted to meet individual career goals. Outcomes assessed include program completion, postgraduation professional roles, and academic outputs and public engagement before and after fellowship matriculation (2019-2023), compared via paired t tests. Results Five fellows have matriculated; 2 have graduated, while 3 remain in training. Costs and in-kind support include salaries, faculty time, research support, travel to conferences, and tuition for a public health degree. Fellows averaged 0.26 outputs per month before matriculation (95% CI 0.01-0.51) and 2.13 outputs per month following matriculation (95% CI 0.77-3.50); this difference was significant via 2-tailed t test (alpha=.05, P=.01). Subanalyses of academic output and public engagement reveal similar increases. Following matriculation, 186 of 191 (97.4%) of outputs were related to climate change. Conclusions For the 5 fellows that have enrolled in this GME climate change fellowship, academic and public engagement output rates increased following fellowship matriculation.

Incorporating Climate Change Education Into Residency: A Focus on Community Risks and Resources.

Journal of graduate medical education, 16(6 Suppl):86-91.

BACKGROUND: Graduate medical education (GME) focused on climate change (CC) health effects is essential. However, few CC education evaluations exist to guide residency programs looking to implement CC content.

OBJECTIVE: To evaluate the effect of an education session on residents' self-reported knowledge of CC health effects and confidence utilizing local CC anticipatory guidance and community resources with patients.

METHODS: A CC session was integrated into the pediatric, family medicine, and social medicine curricula at an urban academic medical center in 2023. A convenience sample of residents participated in 1 of 4 nonrandomized case-based or lecture-based sessions. Pre- and post-session 5-question Likert-scale surveys were used for assessment and analyzed using paired t tests.

RESULTS: Sixty-eight of 108 eligible residents completed the surveys (28 case-based, 40 lecture-based, 63% response rate). Residents' understanding and confidence to engage with patients on CC health effects after the educational session improved (Q1 mean difference 1.3, t 67=9.85, 95% CI 1.04-1.57, P<.001; Q2 1.5, t 67=9.98, 95% CI 1.20-1.82, P<.001; Q3 1.8, t 67=12.84, 95% QI 1.54-2.11, P<.001; Q4 2.1, t 67=16.25, 95% CI 1.84-2.36, P<.001; Q5 2.1, t 67=16.28, 95% CI 1.86-2.38, P<.001).

CONCLUSIONS: Resident self-reported understanding of the health effects of CC and confidence utilizing local CC anticipatory guidance and resources with patients increased after a CC education session.

ClimateMind50+ a comprehensive short questionnaire to measures climate change knowledge, worries, preparedness, behaviours, and involvement of adults aged 50 and over.

medRxiv : the preprint server for health sciences pii:2024.12.02.24318302.

The ClimateMind50+ questionnaire is a tailored instrument to assess the knowledge, concerns, preparedness, behaviours, and involvement of individuals aged 50 and above. Older adults are particularly vulnerable to climate-related hazards such as extreme heat, flooding, and severe storms, yet their perspectives and contributions to climate resilience remain underrepresented in research. The systematic development of the ClimateMind50+ involved rigorous cognitive testing with diverse participants, ensuring clarity, accessibility, and relevance. The tool is designed for versatility in administration-face-to-face, via telephone, or self-completion-facilitating its integration across various research contexts. Cognitive testing highlighted the need for clear wording, simplified response scales, and age-appropriate framing of questions. For instance, questions on climate preparedness and sustainable practices were refined to capture lifetime actions ("ever") rather than limited timeframes, enhancing their relevance for older respondents. Additionally, the questionnaire effectively explores older adults' engagement in climate actions, from individual behavioural changes to advocacy and activism, challenging stereotypes of passivity in this demographic. By providing nuanced insights into the experiences of older adults and their potential contributions to climate mitigation and adaptation, the ClimateMind50+ offers a robust foundation for climate change research among older people. Its deployment can support policymaking and community initiatives aimed at reducing climate risks while promoting sustainable and healthy aging practices. This innovative tool underscores the importance of amplifying the voices of older adults in climate discourse and harnessing their capacities for fostering resilience.

A Review of Theory: Comparing Invasion Ecology and Climate Change-Induced Range Shifting.

Global change biology, 30(12):e17612.

Human actions have led to large-scale shifts in the distributions of species, which have accelerated over recent decades. Two contributing factors include the introduction of non-native species to new regions, and more recently, the shift of species into new ranges to track a human-altered climate. While the context of these species redistributions is different, we argue here that scientists studying the effects of either invasion or range shifting are interested in the same underlying mechanistic questions: (1) What traits make a species likely to survive in a new location? and (2) Which recipient ecosystems are likely to support a newly arrived species? A survey of the theoretical literature surrounding these topics demonstrates the usefulness of this comparison and highlights key differences between range shifting and invasion in factors including genetic diversity, climatic tolerance, local adaptation, and coevolutionary history. This review does not support the blanket application of an invasion framework to climate change-induced range shifts. However, we suggest the use of modified invasion theories, experimental designs, and risk assessments could aid in predicting outcomes and prioritizing management resources for climate-threatened species.

Climate change and its impact on children and adolescents sleep.

Jornal de pediatria pii:S0021-7557(24)00148-7 [Epub ahead of print].

OBJECTIVE: This review discusses the impact of climate change on sleep, anxiety, and eating in the pediatric population.

DATA SOURCE: This is a nonsystematic literature review based on a search using PubMed and MeSH terms in titles and abstracts with these keywords: climate change, sleep, greenhouse effect, children, and adolescents.

DATA SYNTHESIS: Climate change events are associated with human intervention in the ecosystem, having a strong impact on cognitive functions, physical and mental health, as well as subjective well-being, particularly in youth. Climate change is caused by human activity with changes in the composition of the global atmosphere caused by emissions of gases, such as carbon dioxide, which increase the greenhouse effect. This review discusses the impact of climate change on sleep, anxiety, and feeding in the pediatric population.

CONCLUSIONS: Early detection of vulnerability conditions, along with adaptation strategies is necessary to address climate stressors with a focus on healthy sleep and eco-anxiety. Pediatrics has an important role to play in protecting healthy sleep in children.

Simulating fuel management for protecting regional biodiversity under climate change.

Journal of environmental management, 373:123731 pii:S0301-4797(24)03717-4 [Epub ahead of print].

Climate change is resulting in larger, more frequent, and more severe wildfires which have increasingly negative impacts on people and the environment. Under these circumstances, it is critical to determine whether fire management actions can mitigate biodiversity impacts under future fire regimes. However, it is currently unclear how changing climate and management interact to influence the spatial distribution of risks to biodiversity. We used fire simulations to quantify the influence of 13 fuel management strategies on animal biodiversity in the Otways, southeastern Australia, under four alternative climate scenarios. Our management strategies include combinations of prescribed burning, mulching, and strategic fuel breaks modelled in various spatial configurations and frequencies. We assessed the capacity of treatments to reduce risk of fire to animal biodiversity by quantifying changes to extent burnt, wildfire frequency and wildfire severity. All management strategies reduced the average annual area burnt across the landscape, however, there was considerable variability over time and under different climate models. Similarly, spatial shifts in fire frequency and severity in some cases resulted in the shifting of fires away from some areas of high value to animals. There is no one size fits all management strategy for reducing impacts to biodiversity under variable future climates. However, all the strategies tested here reduced median impacts relative to a do-nothing approach for at least some aspects of the fire regime or for animal biodiversity. We highlight the importance of evaluating fire management effectiveness against a range of metrics to ensure multiple objectives are met under the increasingly unknown climate conditions we can expect going forward.

Identifying climate refugia for vulnerable marine ecosystem indicator taxa under future climate change scenarios.

Journal of environmental management, 373:122635 pii:S0301-4797(24)02621-5 [Epub ahead of print].

Vulnerable Marine Ecosystems (VMEs) are recognised as having high ecological significance and susceptibility to disturbances, including climate change. One approach to providing information on the location and biological composition of these ecosystems, especially in difficult-to-reach environments such as the deep sea, is to generate spatial predictions for VME indicator taxa. In this study, the Random Forest algorithm was used to model the spatial distribution of density for 14 deep-water VME indicator taxa under current environmental conditions and future climate change scenarios (SSP2-4.5 and SSP3-7.0) within the New Zealand Territorial Sea and Exclusive Economic Zone (100-1500 m water depth) to evaluate potential changes in the location and distribution of density of these taxa over time. Overall, our species distribution models performed well for all taxa (mean AUC = 0.82; TSS = 0.56; r = 0.40) and predicted a considerable average reduction in density (54%) and habitat extent (61%), by the end of the 21st century under both climate change scenarios. Nevertheless, models identified regions that might serve as internal refugia (approximately 158,000 km[2]), where some taxa are predicted to maintain the high densities predicted for current-day environmental conditions under future climatic conditions, and external refugia (approximately 121,000 km[2]) where taxa were predicted to expand into new locations by the end of the 21st century. Our results represent a significant step forward as they provide predictions of the distribution of taxa densities, rather than just occurrence, under both present and future climatic conditions. Furthermore, these findings carry implications for ecosystem management and spatial planning, suggesting current marine spatial protection measures may not offer adequate protection to VME indicator taxa in the face of climate change. Additionally, activities like bottom trawling, present or future, may jeopardize climate refugia viability. Thus, a comprehensive assessment of cumulative effects on VME indicator taxa is recommended to establish effective protection measures for potential climate refugia, ensuring the continuity of essential ecosystem services.

Estimating the burden of temperature-related low birthweight attributable to anthropogenic climate change in low-income and middle-income countries: a retrospective, multicentre, epidemiological study.

The Lancet. Planetary health, 8(12):e997-e1009.

BACKGROUND: Pregnant individuals are particularly susceptible to non-optimal temperatures due to their physiological status. Moreover, pregnancy is a crucial period for programming fetal health. Quantifying the impact of non-optimal temperature exposure and the contribution of anthropogenic climate change is crucial for mitigating and adapting to climate-related health risks. However, this has not been thoroughly studied in pregnant individuals in low-income and middle-income countries (LMICs).

METHODS: Using data from 511 449 births across 31 LMICs from 1990 to 2018, we linked climate simulations (with and without anthropogenic forcing) to spatiotemporally resolved temperature data and birthweight records. We assessed the association between heat and cold exposure (ie, >90th and <10th percentile of temperature by region) during pregnancy and birthweight across different regions. We then used temperature simulations from both historically forced and natural-only forced climate models to estimate changes in exposure due to anthropogenic climate change and to quantify the burden of temperature-related low birthweight (ie, a birthweight <2500 g) attributable to anthropogenic climate change.

FINDINGS: Heat exposure during pregnancy, compared with the optimal temperature range, was associated with an increased risk of low birthweight in several regions: southern Asia (odds ratio 1·41, 95% CI 1·34-1·48), western Africa (1·12, 1·02-1·24), and eastern Africa (1·40, 1·27-1·55). Cold exposure increased the risk of low birthweight in central Africa (1·31, 1·10-1·56), southern Africa (1·18, 1·02-1·36), and eastern Africa (1·14, 1·02-1·26). Anthropogenic climate change contributed to approximately 59·2% (95% CI 16·6-94·3), 89·0% (51·0-100·0), and 77·3% (27·0-100·0) of heat-related low birthweight cases in southern Asia, western Africa, and eastern Africa, respectively. Conversely, in regions where cold exposure was predominant, anthropogenic climate change reduced the burden of low birthweight.

INTERPRETATION: Our study provides quantitative estimates of the contribution of anthropogenic climate change to the low birthweight burden in LMICs. These findings can inform strategies for climate mitigation and adaptation in LMICs and help reduce global health inequalities.

Intersections between climate change and antimicrobial resistance: a systematic scoping review.

The Lancet. Planetary health, 8(12):e1118-e1128.

Climate change and antimicrobial resistance (AMR) present crucial challenges for the health and wellbeing of people, animals, plants, and ecosystems worldwide, yet the two are largely treated as separate and unrelated challenges. The aim of this systematic scoping Review is to understand the nature of the growing evidence base linking AMR and climate change and to identify knowledge gaps and areas for further research. We conducted a systematic search of the peer-reviewed literature in Scopus, Web of Science, and PubMed on 27 June, 2022. Our search strategy identified and screened 1687 unique results. Data were extracted and analysed from 574 records meeting our inclusion criteria. 222 (39%) of these reviewed articles discussed harmful synergies in which both climate change and AMR exist independently and can interact synergistically, resulting in negative outcomes. Just over a quarter (n=163; 28%) of the literature contained general or broad references to AMR and climate change, whereas a fifth (n=111; 19%) of articles referred to climate change influencing the emergence and evolution of AMR. 12% of articles (n=70) presented positive synergies between approaches aimed at addressing climate change and interventions targeting the management and control of AMR. The remaining literature focused on the shared drivers of AMR and climate change, the trade-offs between climate actions that have unanticipated negative outcomes for AMR (or vice versa), and, finally, the pathways through which AMR can negatively influence climate change. Our findings indicate multiple intersections through which climate change and AMR can and do connect. Research in this area is still nascent, disciplinarily isolated, and only beginning to converge, with few documents primarily focused on the equal intersection of both topics. Greater empirical and evidence-based attention is needed to investigate knowledge gaps related to specific climate change hazards and antimicrobial resistant fungi, helminths, protists, and viruses.

Projecting the overall heat-related health burden and associated economic costs in a climate change context in Quebec, Canada.

The Science of the total environment, 958:178022 pii:S0048-9697(24)08179-8 [Epub ahead of print].

Extreme heat represents a major health risk for the world's population, that is amplified by climate change. However, the health costs associated with these heat events have only been little studied. To stimulate the implementation of effective interventions against extreme heat, a more comprehensive economic valuation of these health impacts is crucial. In this study, a general framework for assessing historical and projected heat-related health costs is presented and then applied to the province of Quebec (Canada). First, heat-related mortality and morbidity, as well as the number of extreme heatwaves, were computed for a historical (∼2000) and projected (∼2050) period under two shared socioeconomic pathways (SSP). Then, these heat-related numbers were converted into 1) direct healthcare costs, 2) indirect productivity costs and 3) intangible societal costs, using the best available cost information. Results showed that historical heat-related health costs were respectively 15M$, 5M$ and 3.6G$ (in 2019 Canadian dollars) annually for the direct, indirect and intangible components in Quebec, Canada. Under a middle-of-the-road scenario (SSP2-4.5), there was a 3-fold increase in total costs due to climate and population change (10.9G$ annually), while under a pessimistic scenario (SSP5-8.5), the increase was 5-fold (17.4G$). Total costs were mostly driven by intangible impacts, such as loss of life (∼90-95%) and of well-being during heatwaves (∼5-10%). Given that heat-related health costs are already significant, and likely to increase substantially in the future, this study has demonstrated the vital need to reduce its burden now and in the future by adopting more measures to mitigate climate change and adapt to heat.

Impact of Climate Change on Human Health.

Iranian biomedical journal, 28(7):78.

INTRODUCTION: One of the challenges of the 21st century is climate change, a detrimental consequence of industrial growth and urbanization and one of the major environmental concerns of this century. Climate change has influenced various aspects of human life. Therefore, this study aimed to examine the effects of climate change on human health.

SEARCH STRATEGY: The study reviewed 32 articles between 2011 and 2023. Research was conducted using databases such as Google Scholar and ScienceDirect, employing keywords such as "climate change," "weather changes," "human health," and "disease."

RESULTS: Studies indicated that climate change and global warming could directly or indirectly cause many health problems. It was estimated that between 2030 and 2050, climate change will result in about 25,000 additional deaths per year due to malnutrition, malaria, diarrhea, and heat stress. Research conducted from 2011 to 2023 showed that climate change can contribute to the emergence or exacerbation of certain diseases and health issues. Among these health problems were changes in certain seasonal diseases, the spread of infectious diseases such as malaria and waterborne illnesses, and issues related to insects. Additionally, cardiovascular diseases, strokes, cholera, asthma, allergies, respiratory diseases, skin cancer, and bladder cancer were of concern. Other health issues included those caused by food and nutrition, heat-related illnesses, emerging fungal infections, heat stress, associated disorders, and complications arising from occupational exposures in hot outdoor environments. Mental health and stress-related disorders were also significant. Recent studies indicated that 37% of deaths associated with heat waves during the warmer months were linked to climate change. Furthermore, there was a notable correlation between climatic parameters and mortality rates from cardiovascular and respiratory diseases, with statistical significance at the 95% and 99% levels.

CONCLUSION AND DISCUSSION: Our findings revealed that global warming is causing significant climate changes, which can change the pattern of weather-related diseases. Although many factors contribute to the occurrence of diseases, extreme heat, increased sun exposure, and cold nights in regions with adverse weather conditions can lead to a rise in the prevalence and progress of human diseases.

Cretaceous coastal mountain building and potential impacts on climate change in East Asia.

Science advances, 10(50):eads0587.

Crustal thickness and elevation variations control mountain building and climate change at convergent margins. As an archetypal Andean-type convergent margin, eastern Asia preserves voluminous magmas ideal for quantifying these processes and their impacts on climate. Here, we use Sr/Y and Ce/Y proxies to show that the crust experienced alternating thickening and thinning during the Late Mesozoic. We identify a noticeably thickened (50 to 55 kilometers) crust associated with tectonic shortening at 120 to 105 million years, corresponding to a >2500-meter-high coastal mountain range. Using climate simulation with the Community Earth System Model, we demonstrate that the mountain uplift changed Asian atmospheric circulation and precipitation patterns, increased inland aridity (~15%), and prompted the eastward desert expansion, contributing substantially to the arid zonal belt across mid- to low-latitude Asia. These findings-compatible with independent geological, geophysical, and climatic observations-have global implications for broadening our understanding of Earth-system interactions in the Cretaceous greenhouse world.

Atmospheres of influence: the role of journal editors in shaping early climate change narratives.

British journal for the history of science pii:S0007087424001304 [Epub ahead of print].

The role of editorial staff in shaping early climate change narratives has been underexplored and deserves more attention. During the 1970s, the epistemological underpinnings of the production of knowledge on climate change were contested between scientists who favoured computer-based atmospheric simulations and those who were more interested in investigating the long-term history of climatic changes. Although the former group later became predominant in the Intergovernmental Panel on Climate Change during the 1980s, the latter had a sizable influence over climate discourse during the 1970s. Of these, one of the key popularizers of climate discourse during the 1970s was the British climatologist Hubert Lamb (1913-97). The correspondence between Lamb and journal editors who gatekept and curated different audiences helped craft resonant messages about climate change and its potential effects, and we explore Lamb's interactions with editors of Nature, the UNESCO Courier, The Ecologist and Development Forum in the 1973-4 period. Through understanding how climate change discussion was influenced by editors, we gain an insight into how such narratives had to be adjusted to fit into pre-existing discourses before their importance was more widely established, and how these adjustments helped shape conceptualizations of climate change as a global, human-caused phenomenon and a source of universal threat.

MaxEnt and Marxan modeling to predict the potential habitat and priority planting areas of Coffea arabica in Yunnan, China under climate change scenario.

Frontiers in plant science, 15:1471653.

INTRODUCTION: Coffea arabica (Arabica coffee) is an important cash crop in Yunnan, China. Ongoing climate change has made coffee production more difficult to sustain, posing challenges for the region's coffee industry. Predictions of the distribution of potentially suitable habitats for Arabica coffee in Yunnan could provide a theoretical basis for the cultivation and rational management of this species.

METHODS: In this study, the MaxEnt model was used to predict the potential distribution of suitable habitat for Arabica coffee in Yunnan under current and future (2021-2100) climate scenarios (SSP2-4.5, SSP3-7.0, and SSP5-8.5) using 56 distributional records and 17 environmental variables and to analyze the important environmental factors. Marxan model was used to plan the priority planting areas for this species at last.

RESULTS: The predicted suitable and sub-suitable areas were about 4.21×10[4] km[2] and 13.87×10[4] km[2], respectively, accounting for 47.15% of the total area of the province. The suitable areas were mainly concentrated in western and southern Yunnan. The minimum temperature of the coldest month, altitude, mean temperature of the wettest quarter, slope, and aluminum saturation were the main environmental variables affecting the distribution of Arabica coffee in Yunnan Province. Changes in habitat suitability for Arabica coffee were most significant and contracted under the SSP3-7.0 climate scenario, while expansion was highest under the SSP5-8.5 climate scenario. Priority areas for Arabica coffee cultivation in Yunnan Province under the 30% and 50% targets were Pu'er, Xishuangbanna, Honghe, Dehong, and Kunming.

DISCUSSION: Climate, soil, and topography combine to influence the potential geographic distribution of Arabica coffee. Future changes in suitable habitat areas under different climate scenarios should lead to the delineation of coffee-growing areas based on appropriate environmental conditions and active policy measures to address climate change.

Frontiers in plant science, 15:1489993.

With the intensification of global climate change, high-temperature and drought stress have emerged as critical environmental stressors affecting tobacco plants' growth, development, and yield. This study provides a comprehensive review of tobacco's physiological and biochemical responses to optimal temperature conditions and limited irrigation across various growth stages. It assesses the effects of these conditions on yield and quality, along with the synergistic interactions and molecular mechanisms associated with these stressors. High-temperature and drought stress induces alterations in both enzymatic and non-enzymatic antioxidant activities, lead to the accumulation of reactive oxygen species (ROS), and promote lipid peroxidation, all of which adversely impact physiological processes such as photosynthetic gas exchange, respiration, and nitrogen metabolism, ultimately resulting in reduced biomass, productivity, and quality. The interaction of these stressors activates novel plant defense mechanisms, contributing to exacerbated synergistic damage. Optimal temperature conditions enhance the activation of heat shock proteins (HSPs) and antioxidant-related genes at the molecular level. At the same time, water stress triggers the expression of genes regulated by both abscisic acid-dependent and independent signaling pathways. This review also discusses contemporary agricultural management strategies, applications of genetic engineering, and biotechnological and molecular breeding methods designed to mitigate adverse agroclimatic responses, focusing on enhancing tobacco production under heat and drought stress conditions.

A macro-level analysis of the socio-economic impacts of climate change driven water scarcity: Incorporating behavioural and resilience aspects.

Water research X, 23:100223.

Recognising the urgent need to address water scarcity resulting from climate change, there is a growing push to enhance the resilience of water (and related) systems. For instance, policymakers are now urging companies to shift from short-term focused strategies towards long-term approaches to effectively manage water scarcity. This paper utilises a custom-built dynamic multisectoral model to assess the socio-economic impacts at a macro-level of temporary water scarcity. The focus of the analysis is to identify the effects that varying levels of investment foresight may have on economic resilience. Specifically, the model incorporates often overlooked factors such as behavioural and resilience aspects. By considering these key elements, a more comprehensive understanding of the system-wide implications of water scarcity on the broader economy is provided. The analysis shows how firms' foresight, or lack thereof, impacts their response to water scarcity and the subsequent impact on the economy. Sector-specific analyses shed light on the potential negative impacts of water scarcity on sectors like agriculture, food, and electricity production and distribution. Yet, the analysis also reveals that certain sectors can benefit from competitiveness effects, which can mitigate the adverse economic implications of water scarcity. However, it should be noted that these sectors may contribute to a catch-up effect on water use. The policy recommendations arising from this research emphasise the promotion of anticipation and preparedness among firms. It is crucial to prioritise resilience-building measures in all sectors, whether they directly rely on water or not.

Effects of climate change on the distribution of Molossus molossus and the potential risk of Orthohantavirus transmission in the Neotropical region.

Acta tropica pii:S0001-706X(24)00381-4 [Epub ahead of print].

Molossus molossus is a widely distributed neotropical bat species in the Americas, often found in urban areas. This study evaluated climate change effects on the potential geographic distribution of M. molossus, a natural host of zoonotic pathogens such as Orthohantavirus, in the Neotropical region. Using ecological niche modeling (ENM), models were generated for current (1970-2000) and future (2070) climate scenarios based on two Shared Socioeconomic Pathways (SSP2-4.5 and SSP5-8.5) and two Global Circulation Models (MPI-ESM1-2-LR and IPSL-CM6A-LR). Results indicated that in the current scenario, warm and coastal areas of the Neotropics are suitable for M. molossus occurrence. Risk areas for Orthohantavirus transmission were mapped by overlapping the probability of urban expansion with projections of climatic suitability for the bat. For both future scenarios (2070), projections indicate an expansion of suitable climatic areas for M. molossus over urban expansion zones, specifically in Brazil, Paraguay, Peru, Ecuador, Costa Rica, Honduras, El Salvador, Guatemala, Belize, Mexico, the United States, Cuba, Haiti, the Dominican Republic, and Puerto Rico. However, projections also indicate the Lesser Antilles under climate threat, considering that no climatic suitability areas will remain. These findings provide important information for planning surveillance and mitigation actions for zoonotic risks associated with M. molossus, considering climate change impacts on its geographic distribution in the Neotropical region.

A preliminary study on the effects of rainfall-related conditions on chromium increase in ultramafic-hosted springs: A possible climate change concern?.

The Science of the total environment, 958:177826 pii:S0048-9697(24)07983-X [Epub ahead of print].

This study investigates the impact of intense rainfall on chromium concentrations in five springs discharging from ultramafic rocks in the Northern Apennines (Italy), which are used for drinking water supply through integration into the local water network. Total chromium concentration increased significantly in response to heavy rain, exceeding the WHO drinking water guideline value (up to 80 μg/L) in one spring and the forthcoming 2036 EU target of 25 μg/L in all the springs. This increase could be attributed to a synergistic combination of factors: i) the reduction of Cr(VI) to Cr(III) by natural organic matter (NOM) in soil and transport as NOM-Cr(III) colloids and/or during the oxidation of magnetite to ferrihydrite in the aquifer; ii) the abundance of detrital ultramafic material in the study area, which may store Cr(III)-bearing colloids too; iii) a triggering effect of first intense rainfall after a 20 dry consecutive days period (wet-dry cycle). Moreover, the persistence of a high Cr(III) concentration in the aquifer even a month after the intense rainfall event aligns with previous laboratory studies on NOM-Cr(III) colloidal stability, which showed that such colloids are highly stable and can persist in solution for at least 20 days.

The issue of climate change and the spread of tropical diseases in Europe and Italy: vector biology, disease transmission, genome-based monitoring and public health implications.

Infectious diseases (London, England) [Epub ahead of print].

BACKGROUND: Climate change significantly influences the distribution and severity of tropical diseases. Rising temperatures, changing precipitation patterns, and extreme weather events are transforming the habitats of vectors like mosquitoes and ticks, promoting their proliferation and geographic spread. These changes have facilitated the resurgence of diseases such as malaria, dengue, and chikungunya fever in previously unaffected areas, including parts of Europe and Italy.

OBJECTIVE AND METHODS: This review aims to explore the relationship between climate change and the spread of vector-borne and tropical parasitic diseases across Europe, with a particular focus on Italy. Recent studies are analyzed to identify emerging trends in disease transmission influenced by shifting climates. Genome-based monitoring and predictive models incorporating climatic and ecological data are highlighted as methods to enhance disease surveillance and preparedness.

RESULTS: The analysis reveals a clear link between climate change and altered disease patterns. The proliferation of vectors into new territories is associated with increased incidence of diseases. Genome-based tools demonstrate their utility in tracking the evolution of pathogens, particularly regarding changes in virulence, drug resistance, and adaptability to new climates. Predictive models have proven effective in anticipating outbreaks and supporting timely public health interventions.

CONCLUSIONS: To mitigate the risks posed by climate-induced changes in disease dynamics, continuous monitoring and international collaboration are essential. Strengthening health systems' resilience through mitigation and adaptation strategies is crucial for preventing future epidemics. These insights contribute to the development of sustainable long-term policies for managing tropical diseases in the context of climate change, ensuring timely responses to public health emergencies.

Heat stress reduces stomatal numbers in Ginkgo biloba: Implications for the stomatal method of palaeo-atmospheric [CO2] reconstruction during episodes of global warming.

The Science of the total environment, 958:177962 pii:S0048-9697(24)08119-1 [Epub ahead of print].

The stomata of fossil plants are commonly used as proxies to reconstruct palaeo-atmospheric carbon dioxide concentrations (palaeo-[CO2]). Stomatal reconstruction of palaeo-[CO2] during global greenhouse periods or episodes of global warming, are particularly important to our understanding of the role of CO2 as a climate system driver. However, the efficacy of the 'stomatal method' for palaeo-[CO2] reconstruction depends upon the strength of the inverse relationship between stomatal number and the [CO2] in which the leaf developed. However, the impact of heat stress on stomatal initiation and development are largely unknown. Ginkgo biloba, a living fossil species, seedlings were grown in controlled environment chambers under 20/25 °C and 30/35 °C night/day temperature regimes. Heat stress in the 30/35 °C treatment impaired photosynthetic function, decreased stomatal conductance (Gs), and reduced stomatal index (SI), indicative of lower stomatal initiation. Modelled theoretical Gs did not correlate with observed measured Gs, undermining the utility of palaeo-[CO2] reconstructions based on stomatal diffusion modelling. The lower stomatal initiation of G. biloba leaves from the higher temperature resulted in greater estimates of [CO2] based on SI values using the nearest living equivalent and SI-[CO2] transfer function approaches. Heat stress may diminish the effectiveness of the stomatal method in reconstructing palaeo-[CO2] during intervals of global warming marked by floral turnover in Earth history.

Climate change driven land use evolution and soil heavy metal release effects in lakes on the Qinghai Tibet Plateau.

The Science of the total environment, 958:177898 pii:S0048-9697(24)08055-0 [Epub ahead of print].

In recent decades, global warming has intensified hydrological cycles, raising concerns about the impacts of climate change on hydrological processes, water quality, and water resources across various temporal and spatial scales. These changes significantly affect water resource management and environmental protection policies and may also influence the ecological health and socio-economic well-being of lake regions. Qinghai Lake, the largest inland lake and a major water source reservoir in China, plays a crucial role in the ecological security of the Qinghai-Tibet Plateau. However, in recent years, with the ongoing development of the economy and society throughout the province, there has been an increase in algal blooms in the nearshore area of Qinghai Lake, with the affected area expanding annually. There is currently no clear consensus on the causes of eutrophication in lakes, and comprehensive, in-depth research on how different land use types-critical to the material migration and transformation processes of natural water bodies-affects water quality and ecological security, as well as the interactions between nutrients and heavy metals, is lacking. Therefore, it is essential to monitor and understand the effects of climate change on lakes and to develop adaptive strategies to mitigate and respond to these impacts amidst rapid economic and social development. The lake environmental pollution early warning system developed in this study provides a scientific research paradigm for lake water pollution control and offers valuable data support for policymakers in formulating ecological protection and development strategies.

ESP Quick Facts

ESP Origins

In the early 1990's, Robert Robbins was a faculty member at Johns Hopkins, where he directed the informatics core of GDB — the human gene-mapping database of the international human genome project. To share papers with colleagues around the world, he set up a small paper-sharing section on his personal web page. This small project evolved into The Electronic Scholarly Publishing Project.

ESP Support

In 1995, Robbins became the VP/IT of the Fred Hutchinson Cancer Research Center in Seattle, WA. Soon after arriving in Seattle, Robbins secured funding, through the ELSI component of the US Human Genome Project, to create the original ESP.ORG web site, with the formal goal of providing free, world-wide access to the literature of classical genetics.

ESP Rationale

Although the methods of molecular biology can seem almost magical to the uninitiated, the original techniques of classical genetics are readily appreciated by one and all: cross individuals that differ in some inherited trait, collect all of the progeny, score their attributes, and propose mechanisms to explain the patterns of inheritance observed.

ESP Goal

In reading the early works of classical genetics, one is drawn, almost inexorably, into ever more complex models, until molecular explanations begin to seem both necessary and natural. At that point, the tools for understanding genome research are at hand. Assisting readers reach this point was the original goal of The Electronic Scholarly Publishing Project.

ESP Usage

Usage of the site grew rapidly and has remained high. Faculty began to use the site for their assigned readings. Other on-line publishers, ranging from The New York Times to Nature referenced ESP materials in their own publications. Nobel laureates (e.g., Joshua Lederberg) regularly used the site and even wrote to suggest changes and improvements.

ESP Content

When the site began, no journals were making their early content available in digital format. As a result, ESP was obliged to digitize classic literature before it could be made available. For many important papers — such as Mendel's original paper or the first genetic map — ESP had to produce entirely new typeset versions of the works, if they were to be available in a high-quality format.

ESP Help

Early support from the DOE component of the Human Genome Project was critically important for getting the ESP project on a firm foundation. Since that funding ended (nearly 20 years ago), the project has been operated as a purely volunteer effort. Anyone wishing to assist in these efforts should send an email to Robbins.

ESP Plans

With the development of methods for adding typeset side notes to PDF files, the ESP project now plans to add annotated versions of some classical papers to its holdings. We also plan to add new reference and pedagogical material. We have already started providing regularly updated, comprehensive bibliographies to the ESP.ORG site.
