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.

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.

Creating a Public Service Announcement as a Teaching Strategy to Advocate for Populations at Risk due to Climate Change.

Nursing education perspectives [Epub ahead of print].

The 2022 National League for Nursing Vision Statement, Climate Change and Health, identified gaps in nursing education regarding the issue of climate change and its impact on at-risk populations. Our innovative teaching strategy requires nursing students to use clinical judgment to synthesize ideas and communicate the health risks of climate change for population at risk in a brief video or public service announcement. This teaching strategy can prepare nursing students to advocate for population health.

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.

[From ozone depletion to the lens: effects of climate change on cataract progression].

Die Ophthalmologie [Epub ahead of print].

The incidence of cataract is expected to increase, primarily due to an aging population. However, human-induced environmental changes may also contribute. In this narrative review, we explore the connection between climate change, the depletion of the ozone layer, and modifiable risk factors for cataract development such as UV light exposure and pollution-related factors. Finally, we discuss preventative measures at both the individual and the societal level, including strategies to improve cataract care and reduce the carbon footprint of cataract surgery.

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.

Climate Change Curriculum in a Network of US Family Medicine Residency Programs.

Journal of graduate medical education, 16(6 Suppl):78-85.

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.

Tobacco production under global climate change: combined effects of heat and drought stress and coping strategies.

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.

Imperative for a health-centred focus on climate change in radiology.

Journal of medical imaging and radiation oncology [Epub ahead of print].

Climate change negatively impacts individual and population-level health through multiple pathways, including poor air quality, extreme heat and changes in infectious disease. These health effects will lead to higher health system and medical imaging utilisation. At the same time, the delivery of radiology services generates substantial greenhouse gas emissions. Mitigation strategies to reduce the environmental impact of medical imaging and adaptation strategies to build resiliency to current and future impacts of climate change in radiology should be centred on human health. A health-centred response in radiology reinforces the role of radiologists as physicians and emphasises the opportunity for medical imaging to promote health and advance our understanding of climate-related health effects. This review discusses the need for a health-centred focus on climate change in radiology, including the effects of climate change on human health and health systems, intersection of climate change with health equity, health benefits of climate action and opportunities to leverage medical imaging to improve human health.

Climate Change and Mental Health.

Annual review of clinical psychology [Epub ahead of print].

Climate change negatively threatens mental health through acute, chronic, indirect, and vicarious pathways. Though these psychological consequences will be felt globally, specific populations are at increased risk. This article describes the complex and diverse ways in which climate change can affect mental health and the resulting challenges that health care services will inevitably face. In responding to these threats, both prevention and intervention are urgently needed. Although mitigating the extent of climate change is crucial, we can also foster resilience to climate change-the ability to manage, respond to, and prepare for climate-related adversity-at the systemic, community, and individual levels. The mental health field must prepare for the significant burden that climate change will place on population health and well-being in the long term. In this review, we aim to inform and provide examples of how decision makers, the mental health discipline, and mental health professionals can respond.

Integration of Multiple Climate Change Mitigation Actions and Health Co-Benefits: A Framework Using the Global Calculator.

Environmental health perspectives, 132(12):125001.

BACKGROUND: The Global Calculator is an open-source model of the world's energy, land, and food systems. It is a pioneering online calculator to project the impact of interventions to mitigate climate change on global temperature. A few studies have been conducted to evaluate the health co-benefits of climate change mitigation, though they are still fragmentary.

OBJECTIVES: Our objectives are to identify which sectors could yield the greatest results in terms of climate change mitigation and suggest whether existing evidence could be used to weight mitigation actions based on their ancillary impacts on human health or health co-benefits.

METHODS: Using the International Energy Agency (IEA) 4DS scenario as a referent (i.e., the "4-degree Celsius increase scenario"), we simulated changes in different policy "levers" (encompassing 43 potential technological and behavioral interventions, grouped by 14 sectors) and assessed the relative importance of each lever in terms of changes in annual greenhouse gas emissions in 2050 and cumulative emissions by 2100. In addition, we examined existing estimates for the health co-benefits associated with different interventions, using evidence from the Lancet Pathfinder and four other tools.

DISCUSSION: Our simulations suggest that-after accounting for demographic change-transition from fossil fuels to renewables and changes in agriculture, forestry, land use, and food production are key sectors for climate change mitigation. The role of interventions in other sectors, like carbon capture and storage (CCS) or nuclear power, is more modest. Our work also identifies mitigation actions that are likely to have large health co-benefits, including shifts to renewable energy and changes in land use as well as dietary and travel behaviors. In conclusion, some of the sectors/interventions which have been at the center of policy debate (e.g., CCS or nuclear power) are likely to be far less important than changes in areas such as dietary habits or forestry practices by 2050. https://doi.org/10.1289/EHP14906.

Is Ecological Anxiety Due to Climate Change Associated With the Fertility Preferences of Women?.

Journal of evaluation in clinical practice, 31(1):e14265.

BACKGROUND: Eco-anxiety caused by climate change, which is a significant public health problem, has negative effects on sexual and reproductive health, and these effects are expected to increase continuously. This study was conducted to determine the relationship between eco-anxiety caused by climate change and the fertility preferences of women.

METHODS: This descriptive study was conducted between June and August 2024 with 491 women at the ages of 18 to 49 who were registered at a family health center. A personal information form, the Attitudes toward Fertility and Childbearing Scale, and the Hogg Eco-Anxiety Scale were used to collect data.

RESULTS: The mean total AFCS score of the participants was 66.1 ± 14.2, while their mean total HEAS score was 27.1 ± 7.0. There was a weak negative correlation between the AFCS scores and HEAS scores of the participants (r = -0.124, p = 0.006).

CONCLUSION: As the ecological anxiety levels of women increased, their attitudes toward childbearing became more negative.

Climate change and polar marine invertebrates: life-history responses in a warmer, high CO2 world.

The Journal of experimental biology, 227(23):.

Polar marine invertebrates serve as bellwethers for species vulnerabilities in the face of changing climate at high latitudes of the Earth. Ocean acidification, warming/heatwaves, freshening, sea ice retreat and productivity change are challenges for polar species. Adaptations to life in cold water with intensely seasonal productivity has shaped species traits at both poles. Polar species have life histories often characterised as K-strategist or K-selected (e.g. slow growth and development, larval hypometabolism) that make them sensitive to climate stress and altered seasonal productivity. Moderate warming results in faster development and can have positive effects on development, up to a limit. However, ocean acidification can retard development, impair skeletogenesis and result in smaller larvae. Given the fast pace of warming, data on the thermal tolerance of larvae from diverse species is urgently needed, as well as knowledge of adaptive responses to ocean acidification and changes to sea ice and productivity. Predicted productivity increase would benefit energy-limited reproduction and development, while sea ice loss negatively impacts species with reproduction that directly or indirectly depend on this habitat. It is critical to understand the interactive effects between warming, acidification and other stressors. Polar specialists cannot migrate, making them susceptible to competition and extinction from range-extending subpolar species. The borealisation and australisation of Arctic and Antarctic ecosystems, respectively, is underway as these regions become more hospitable for the larval and adult life-history stages of lower-latitude species. Differences in biogeography and pace of change point to different prospects for Arctic and Antarctic communities. In this Commentary, we hypothesise outcomes for polar species based on life history traits and sensitivity to climate change and suggest research avenues to test our predictions.

Does Climate Change Pose a Threat to the Guild Mimicry System of Australian Orchids?.

Ecology and evolution, 14(12):e70633.

Global warming is one of the biggest threats to global biodiversity causing not only changes in the patterns of precipitation and temperature but also disturbing ecological interactions. The aim of our study was to forecast the effect of climate change on the distribution of food-deceptive orchid species whose pollination strategy relies on a strict association with pollinators and co-occurring rewarding Faboideae plants. We used the ecological niche modeling approach to evaluate future overlap of the suitable niches of studied orchid species with the predicted distribution of their ecological partners. Models were made based on two different global circulation models (FIO, CNRM). CNRM projections predict expansion of orchids' geographical range. In contrast, FIO prediction is less optimistic, forecasting species range contraction. The studied Faboideae species showed different responses to predicted global warming with no consistent patterns in how their suitable niches might change. Most climate change projections and scenarios of the future modifications of temperature and precipitation patterns do not predict significant loss of suitable niches of Trichocolletes bees (Colletidae) pollinating Diuris species. However, global warming has the potential to disrupt interactions between the studied orchids and their co-occurring pea plants by altering the overlap of their geographical ranges which can further disturb pollination success. CNRM projections predict an overall loss of Faboideae within the potential geographical range of Diuris brumalis. Conversely, FIO projections suggest a less extensive predicted divergence. Our simulations offer suggestions for conservation strategies of orchids and potentially for other species that have a similar pollination strategy. The areas indicated here as suitable in the future for the occurrence of all ecological partners can be important climate refugia to consider in local conservation plans. The approach used in our study can serve as a model for understanding the potential effects of climate change on the strength of the pollination system via food deception.

What is limiting how we imagine climate change adaptation?.

Current opinion in environmental sustainability, 71:101476.

Imaginaries of adaptation are currently dominated by technocratic, homogenous, top-down approaches that hinder sustainable, just, and effective adaptation worldwide. We have identified three practices that contribute to this problem: (1) an assumption of universality in adaptation; (2) a neglect of pluralistic knowledge systems and values; and (3) an oversimplification of adaptation processes. These three practices have been found to lead to reproductions of vulnerabilities, unsustainable outcomes, or ephemeral changes. New ways of conceptualising and doing adaptation are necessary to expand imaginaries and visions around what adaptation can and cannot be. Through two examples (everyday adaptations and nature-based solutions), our review indicates that expanding or adopting alternative imaginaries of adaptation can help localise adaptation practice, particularly by acknowledging the need for multiple forms of knowledge and the iterative nature of adaptation governance processes.

With a little help from my friends: Social support, hope and climate change engagement.

The British journal of social psychology, 64(1):e12837.

Hope is a future-oriented emotion that attunes people to the possibility of positive change, and thus could potentially catalyse societal engagement with climate change. A recent meta-analysis suggests that the relationship between hope and climate action is most robust when the target of hope is climate engagement (i.e. action hope) rather than climate change more broadly. Yet, this previous meta-analysis also suggests that fostering action hope and climate engagement may be challenging via typical short media messages used in many studies. Here we consider an alternative source of action hope: receiving social support. Two studies tested whether social support motivates climate action via increased action hope. Study 1 (correlational online survey, pre-registered, N = 887) demonstrates that, as predicted, both instrumental and emotional support predict intentions to take civic action and these effects are explained by action hope. Study 2 (field study, Neducators = 84, Ncontacts = 520) mostly replicates and extends these findings in a field setting, demonstrating that social support recipients' action hope is also associated with social support reported by support providers (here, environmental educators) and that this action hope again explains a possible relationship between social support and climate engagement.

Investigating the Effects of Climate Change on the Prevalence of Dengue Fever.

Iranian biomedical journal, 28(7):58.

INTRODUCTION: Climate change is any change in weather parameters such as temperature and rainfall for a long time and may be caused by natural factors or human activities. Today, climate change has unwanted consequences for health worldwide, and dengue fever is among these diseases. Dengue (bone-breaking fever) is the most common disease transmitted by the Aedes mosquito infected with dengue virus worldwide, affecting more than 200 million people every year. This disease is characterized by fever, malaise, headache, and rash. The present study aimed to investigate the effects of climate change on the prevalence of dengue fever.

SEARCH STRATEGY: The search for keywords such as "dengue fever", "climate change", and "Aedes" was performed in the PubMed database and Google Scholar search engine and their Persian equivalents in the internal databases such as SID and CIVILICA from 2010 to 2024. In the initial search, 259 articles were extracted and included in the study, followed by reviewing 26 articles.

RESULTS: Weather influenced dengue in three aspects: the virus, vector, and transmission environment. The virus underwent part of its development within the vector mosquito, and its life cycle was dependent on temperature, rainfall, and humidity. Two mosquitoes, Aedes aegypti and Aedes albopictus, adapted to human habitations by laying eggs in both natural (tree holes) and artificial (water tanks, pots, bottles, and containers) environments. Heavy rainfall washed away these eggs and larvae from these reservoirs; however, stagnant water can create ideal breeding conditions. An increase in temperature accelerates the reproduction and growth rates of mosquitoes while also shortening the virus's incubation period. Conversely, if temperatures exceed 44 °C, the risk of dengue transmission diminishes due to the desiccation of mosquito breeding sites. During the cold period,adult mosquitoes died, but their eggs survived. High relative humidity also increased the metabolic process in adult mosquitoes. Therefore, in the wet season, the incidence of dengue was the highest, and the disease was less common in the dry season. Also, climate change weakened human immunity against the disease.

CONCLUSION AND DISCUSSION: Climate change influences the transmission of the disease by changing the geographic range of the vector, increasing reproduction, biting, and shortening the incubation period. Solutions such as the development of renewable energy sources and the enhancement of public awareness should be implemented to address climate change.

Phenological divergence between plants and animals under climate change.

Nature ecology & evolution [Epub ahead of print].

Climate change has altered the timing of recurring biological cycles in both plants and animals. Phenological changes may be unequal within and among trophic levels, potentially impacting the intricate interactions that regulate ecosystem functioning. Here we compile and analyse a global dataset of terrestrial phenological observations, including nearly half a million time series for both plants and animals. Our analysis reveals an increasing phenological asynchronization between plants and animals from 1981 to 2020, with a stronger overall advancement of late-season phenophases for plants than for animals. Almost 30% of temporal variations in plant phenophases can be explained by the timing of the preceding phenophases. This temporal dependency allows the advancement caused by warming to accumulate and propagate through seasons, advancing later phenophases more than earlier phases. By contrast, animals rely on various environmental cues and resource-tracking strategies to initiate their life-cycle activities, which weakens their cross-phenophase linkage and undermines the effect of warming. Our results suggest that future warming may increase phenological asynchronization between plants and animals and potentially disturb trophic interactions and ecosystem stability.

Monitoring fungi and mycotoxin potential in pistachio nuts of Turkish origin: A snap-shot for climate change scenario.

Fungal biology, 128(8 Pt B):2431-2438.

Pistachio (Pistacia vera L.) is an economically important tree nut. Due to its nutritional properties and health benefits, it is considered a healthy food and thus widely consumed worldwide. However, fungal contamination of the commodities has received considerable attention because of possible contamination by toxigenic fungi, important source of mycotoxins, resulting from secondary metabolism and hazards to health consumer. Members of the genus Aspergillus, mainly Aspergillus flavus and Aspergillus niger, are reported as occurring most frequently on pistachio nuts, because able to grow in the presence of low amounts of water and to produce mycotoxins (aflatoxins and ochratoxins), that are well known for their harmful health effects on humans. Monitoring the contaminating fungal species is particularly worthy of note also in climate change scenario, allowing to notice changes in fungal population composition through the time. This study aimed to contribute to collect data about fungal population and mycotoxins occurred in pistachio samples collected in Turkey: prevalence of 2 species, A. flavus and Aspergillus tubingensis, was assessed. The A. flavus strains consisted of a mixed population of aflatoxin producers and non-producing strains in vitro, with evidence of a new genotype in gene cluster within strains of aflatoxin non-producing chemotype.

Using environmental and exercise physiology to address gender inequalities in climate change and occupational health research.

Experimental physiology [Epub ahead of print].

Climate change is a health-risk and health-inequity multiplier with excessive heat exposure a direct climate change impact already affecting the health and livelihood of billions globally. Women face greater risks and burdens from climate change impacts. Biological sex may or may not influence an individual's thermoregulatory capacity, heat tolerance or heat susceptibility. However at a population level, sex differences in physiological characteristics (anthropometrics, aerobic capacity, etc.) likely affect thermoregulatory capacity. Still, gender appears to play the most significant role in heat exposure and resulting health impacts. For climate change resilience and adaptation strategies to be effective, public health and occupational guidance/governance must be based on comprehensive and representative evidence. The current dearth of empirical evidence on how excessive heat exposure affects women prohibits this. Environmental and exercise physiology can help address this lack of empirical evidence by adhering to inclusive research guidelines. This paper is based on a symposium presentation given at Physiology 2023 in Harrogate, UK. Using a multi-year cohort study on industrial agricultural workers (the Adelante Initiative) as a case study, this review discusses the role of environmental and exercise physiology in generating inclusive research and evidence to inform occupational and public health guidance/governance for climate change resilience and adaptation, specifically heat exposure.

Symptoms and Diseases Related to Occupational Health Caused by Climate Change: A Systematic Literature Review.

Iranian biomedical journal, 28(7):41.

INTRODUCTION: One of the duties of occupational health engineers is to maintain and improve the physical health of employees. Climate change can cause various symptoms and diseases in workers. The importance of climate change has led to the slogan of World Occupational Safety and Health Day in 2024 being related to the effects of climate change on occupational health. This study aimed to investigate the symptoms and diseases related to occupational health caused by climate change.

SEARCH STRATEGY: The protocol of this study was prepared and presented according to the Preferred Reporting Items for Systematic Reviews and Meta-Analysis (PRISMA) guidelines. Relevant keywords between 2000 and 2024 were searched in authoritative academic databases (PubMed, Scopus, Web of Science, ScienceDirect, and Google Scholar) to identify studies. Scientifically valid studies retrieved by two researchers were reviewed based on inclusion and exclusion criteria, and duplicate and irrelevant articles were excluded. Based on the purpose of the study, the necessary information was extracted from the selected articles and analyzed with a descriptive approach.

RESULTS: In this systematic review, 29 eligible studies were examined. Climate change resulted in various symptoms and diseases in workers. Symptoms caused by climate change in workers included heat stress, heatstroke, fatigue, dehydration, headache, thirst, heat rash, collapse, muscle cramps, excessive sweating, visual disturbances, and reduced chemical tolerance. Additionally, based on the results of various studies, climate change affected chronic kidney diseases, skin cancer, cardiovascular dysfunction, and infectious and contagious diseases such as malaria and Lyme. Our results showed the effect of climate change on workers' cardiorespiratory health problems, including asthma, lung cancer, heart attacks, stroke, and other cardiovascular diseases. Furthermore, heat-related death was the most significant consequence of climate change on workers.

CONCLUSION AND DISCUSSION: Climate change causes various symptoms and diseases in workers, negatively affecting their occupational health. Considering the results of the current research and the importance of the subject, occupational health engineers and other individuals related to workers' health should take necessary measures.

Impacts of Climate Change Conditions on the Potential Distribution of Anoplophora glabripennis and Its Host Plants, Salix babylonica and Salix matsudana, in China.

Ecology and evolution, 14(12):e70692.

The Anoplophora glabripennis (Motschulsky) is a phytophagous pest that is seriously endangering Salix babylonica Linn. and S. matsudana Koidz. Poor control can damage local ecosystems, resulting in economic losses and management risks. In the context of climate change, the climatic ecological niche of organisms is no longer compatible with the surrounding environment. To mitigate the effects of climate change, some organisms respond adaptively to climate change through different mechanisms and in different ways. In this study, an optimized MaxEnt model was used to explore the potential distribution areas of A. glabripennis and its host plants, S. babylonica and S. matsudana, in response to current and future climate and to determine their movement routes and relative dynamics. The results show that the optimized model exhibits the lowest complexity and excellent prediction accuracy. It is important to note that both temperature and precipitation are the main environmental factors affecting the distribution of suitable habitats for A. glabripennis and its host plants. This is evidenced by the mean temperature of the warmest quarter and precipitation of the wettest month being the main environmental factors affecting the distribution of suitable habitats for the host plants. Similarly, the minimum temperature of the coldest month and precipitation seasonality are the primary bioclimatic variables constraining the dispersal of A. glabripennis. Under climate change, the suitable areas of both S. babylonica and S. matsudana are declining, while the suitable areas of A. glabripennis are expanding in future climates. Furthermore, three species exhibited a proclivity for migration to higher latitudes in response to climate change. In conclusion, this study contributes to our understanding of the biogeographic characteristics of these A. glabripennis, S. babylonica, and S. matsudana and provides a basis for the formulation of timely conservation strategies to reduce the potential impacts of climate change. This is of great significance for the rational management, utilization, and protection of forest ecosystems in China.

The role of indigenous knowledge in disaster risk reduction and climate change adaptation in Chikwawa, Malawi.

Jamba (Potchefstroom, South Africa), 16(2):1810.

UNLABELLED: The role of indigenous knowledge in disaster risk reduction (DRR) and climate change adaptation cannot be underestimated. It acts as a preparedness and response tool to climate change-related impacts such as floods, droughts and strong winds. However, inadequate studies about indigenous knowledge in Malawi is a major challenge when dealing with extreme climatic conditions. Learning from indigenous knowledge systems, by investigating first what local communities know and have, can improve the understanding of local conditions and can provide a productive context for activities designed to help communities reduce vulnerability to climate change impacts. This paper assessed the role of indigenous knowledge systems in DRR and climate change variability and adaptation strategies in Chikwawa district. The study used a participatory research approach involving interactive research methods such as focus group discussions (FGDs), key informant interviews and participant observations. Data from key informants and FGDs were analysed thematically. The study revealed various indigenous knowledge which communities in the Chikwawa district use to respond to climate-related impacts such as floods. Some of these include hippopotamus relocating from the river to the village, extreme hissing of pythons in nearby forests, buffaloes and zebras wreaking havoc in the villages and crocodiles flocking to the village.

CONTRIBUTION: The study concludes that indigenous knowledge provides the basis for problem-solving approaches for local communities, hence, a need to document it at a wider scale.

Climate change and hunter-gatherers in montane eastern DR Congo.

Climate and development, 14(5):431-442.

Mountain environments experience more rapid changes in temperature than lower elevations. However, little is known about the climatic changes already observed in African mountains, or the adaptation strategies used by hunter-gatherer communities. Semi-structured interviews were administered to 100 Twa hunter-gatherers living around Mt Kahuzi in eastern Democratic Republic of the Congo (DR Congo). We also organized 10 focus-group discussions with Tembo farmers living in the same area and we gathered historical from Kamembe meteorological station. Twa respondents perceived reduced rainfall and fog, and increased temperatures. They also reported reduced crop yields and abundance of forest products (caterpillars, mushrooms, honey). Tembo perceptions of climatic changes and impacts agreed with the Twa. Meteorological data available shows reduced rainfall and increased temperatures - but there are no records on fog. Despite being aware of climatic changes and impacts, Twa are not using any adaptation strategy, while Tembo farmers are using some (as they own land for farming or animal rearing, and are more business minded). For the Twa, their socioeconomic condition create high sensitivity to climate change and constrain adaptive capacity. To help the Twa, we recommend the use of "science with society" (SWS) participatory approach.

Changes in reproduction mediate the effects of climate change and grassland management on plant population dynamics.

Ecological applications : a publication of the Ecological Society of America [Epub ahead of print].

Climate change is one of the largest threats to grassland plant species, which can be modified by land management. Although climate change and land management are expected to separately and interactively influence plant demography, this has been rarely considered in climate change experiments. We used a large-scale experiment in central Germany to quantify the effects of grassland management, climate change, and their joint effect on the demography and population growth rate of 11 plant species all native to this temperate grassland ecosystem. We parameterized integral projection models with five years of demographic data to project population growth rate. We hypothesized that plant populations perform better in the ambient than in the future climate treatment that creates hotter and drier summer conditions. Further, we hypothesized that plant performance interactively responds to climate and land management in a species-specific manner based on the drought, mowing, and grazing tolerances as well as the flowering phenology of each species. Due to extreme drought events, over half of our study species went quasi extinct, which highlights how extreme climate events can influence long-term experimental results. We found no consistent support for our expectation that plants perform better in ambient compared with future climate conditions. However, several species showed interactive responses to the treatments, indicating that optimal management strategies for plant performance are expected to shift with climate change. Changes in population growth rates of these species across treatments were mostly due to changes in plant reproduction. Experiments combined with measuring plant demographic responses provide a way to isolate the effects of different drivers on the long-term persistence of species and to identify the demographic vital rates that are critical to manage in the future. Our study suggests that it will become increasingly difficult to maintain species with preferences for moister soil conditions, and that climate and land use can interactively alter demographic responses of the remaining grassland species.

Impacts of climate change risk and economic policy uncertainty on carbon prices: Configuration analysis from a complex system perspective.

Journal of environmental management, 373:123622 pii:S0301-4797(24)03608-9 [Epub ahead of print].

Despite a vast amount of research examining the antecedent variables of carbon prices, the impact of climate change risk on carbon prices has been rarely explored. This study adopted a complex system perspective and applied NCA and fsQCA models to analyze regional climate physical risk (CPR) and climate transition risk (CTR) from a complex system perspective. The results suggested that the primary factors affecting the Hubei carbon price included coal prices, market regulation, and national carbon market prices, and carbon prices could be higher in response to higher levels of economic policy uncertainty (EPU) combined with other factors. By comparing the changes of independent variables before and after the opening of the national carbon market, it was found that lower CPR and CTR were conducive to higher carbon prices; the former has received early attention but the latter has been neglected. The findings from this study provided theoretical and practical insight to inform government regulation of carbon prices and decision-making for carbon market stakeholders. The government should pay attention to the impacts of climate change risks and EPU on carbon prices because these factors could significantly undermine the incentive and economic effectiveness of the carbon market.

Advanced Prediction of PM10 Trends Using ANN-NARX Under CMIP6 Climate Change Scenarios.

Iranian biomedical journal, 28(7):3.

INTRODUCTION: As climate change continues to reshape our environment, accurately forecasting air quality becomes essential for developing effective public health and environmental strategies. This study investigates changes in particulate matter (PM10) concentrations under the Shared Socioeconomic Pathways of the Climate Model Intercomparison Project Phase 6 (CMIP6).

METHODS AND MATERIALS: Historical climatic data (1998-2014) were collected to establish baseline conditions, and vital climatic variables-maximum and minimum temperatures, precipitation, and radiation-were gathered between 2013 and 2022 from the Iran Meteorological Organization. The Long Ashton Research Station Weather Generator (LARS-WG 6.0) software was used to perform statistical downscaling, generating high-resolution time series datasets from the historical climatic data. The MIROC6 atmospheric circulation models simulated future climate scenarios using three Shared Socioeconomic Pathways (SSPs) from the sixth IPCC Assessment Report (AR6): optimistic (SSP1-2.6), intermediate (SSP2-4.5), and pessimistic (SSP3-7.0). Monthly PM10 concentrations were obtained from MODIS satellite images. An Artificial Neural Network Nonlinear Autoregressive with Exogenous Input (ANN-NARX) model was developed using the collected climatic variables as predictors, and this model was used to estimate PM10 concentrations for the period 2023-2042 under each SSP scenario.

RESULTS: In various SSP scenarios, PM10 levels were assessed between 2023 and 2042. An increase in PM10 was observed across all scenarios, particularly during the hotter months of summer and spring over the next 20 years. The SSP2-4.5 scenario showed minimal change, maintaining levels close to historical data. In contrast, SSP3-7.0 exhibited significant increases in PM10, especially during the warmer months of summer and spring. Sensitivity analysis identified radiation and maximum temperature as critical factors influencing PM10 predictions, with sensitivity plots showing a notable increase in MSE when these factors were removed. The ANN-NARX model demonstrated satisfactory performance across the training, validation, and testing sets, with RMSE values ranging from 0.15 to 0.30, MAE values from 0.10 to 0.35, and MSE values from 0.01 to 0.1, and R values from 0.91 to 0.92.

CONCLUSION AND DISCUSSION: The study concluded that PM10 concentrations in Ahvaz were significantly influenced by radiation and maximum temperature. The anticipated temperature increases under various SSP scenarios suggest a potential decline in future air quality, with expected rises in PM10 levels. These findings underscore the urgent need for effective air quality management and climate adaptation strategies in Ahvaz.

Atmospheric reaction of CH2=CHCH2OCF2CHF2 with OH radicals and Cl atoms, UV and IR absorption cross sections, and global warming potential.

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

In this work, the rate coefficients for OH radical, k1(T), and Cl atom, k2(T), reaction with allyl 1,1,2,2-tetrafluoroethyl ether, CH2=CHCH2OCF2CHF2, were studied as a function of temperature and pressure in a collaborative effort made between UCLM, Spain, and LAPKIN, Greece. OH rate coefficients were determined in UCLM, between 263 and 353 K and 50-600 Torr, using the absolute rate method of pulsed laser photolysis-laser-induced fluorescence technique, while Cl kinetics were studied in temperature (260-363 K) and pressure (34-721 Torr) ranges, using the relative rate method of the thermostated photochemical reactor equipped with Fourier transform infrared spectroscopy as the detection technique. In both OH and Cl reactions, a negative temperature dependence of the measured rate coefficients was observed, which is consistent with complex association reactions. The temperature dependence of OH rate coefficients was found to be well represented by the following expression: k1(T) = (2.30 ± 0.35) × 10[-12] exp[(544 ± 46) K/T] cm[3] molecule[-1] s[-1]. In the case of the Cl-initiated reaction, a slight curvature was observed in the Arrhenius plot for k2(T), and the kinetic data were fitted to a modified Arrhenius expression: k2(T) = (4.42 ± 0.32) × 10[-16] T[2] exp[(610 ± 22) K/T] cm[3] molecule[-1] s[-1]. No pressure dependence was observed in either case. These results are consistent with a complex reaction mechanism that is not uncommon in radical association reactions to the unsaturated bond. As part of this work, UV (200-400 nm) and infrared absorption spectra (500-3200 cm[-1]) were also measured to further evaluate CH2=CHCH2OCF2CHF2 atmospheric impact. Atmospheric lifetimes with respect to OH radical and Cl atom reactions were estimated to be 19.8 h and 38 days, respectively, showing that OH radicals dominate atmospheric oxidation. CH2=CHCH2OCF2CHF2 is a very weak absorber in the solar actinic region, while its relatively low radiative efficiency in the atmospheric IR window, 0.0034 W m[-2] ppbv[-1], and the short lifetime led to a very low GWP value relative to CO2, 1.2 × 10[-2] and 3.3 × 10[-3], at time horizons of 20 and 100 years, respectively.

Role of macroalgal blue carbon ecosystems in climate change mitigation.

The Science of the total environment, 958:177751 pii:S0048-9697(24)07908-7 [Epub ahead of print].

This review explicitly emphasizes the important yet unnoticed potential of macroalgae, such as seaweeds and kelps, as a powerful nature-based solution for climate change mitigation, with greater focus on the Indian Ocean seaweed diversity and efforts towards their conservation and management. Despite the IPCC's recognition of Blue Carbon ecosystems, seaweed ecosystems remain largely excluded from carbon accounting and policy frameworks. Herein, we specifically focus on the immense capacity of macroalgae globally and in the Indian Ocean coastal communities to sequester carbon, support marine biodiversity, and provide a range of ecosystem services. Through comprehensive analysis of existing literature on the primary productivity, species distribution and carbon sequestration capabilities of seaweeds, we highlight their pivotal role in carbon capture and utilization within a circular economy model. This review explores the ecosystem services provided by both wild and cultivated seaweeds, advocating for innovative applications and responsible management practices to maximize their climate mitigation potential. Our investigation identifies significant knowledge gaps and barriers in the conservation of economically significant, dwindling populations of seaweeds in the Indian Ocean and the integration of seaweed ecosystems into blue carbon policies, including the need for standardized classification, valuation, and long-term conservation strategies. Further, we address the impact of anthropogenic activities on wild seaweed biodiversity and the necessity for reliable carbon removal technologies to support seaweed aquaculture beds. This review urges policy reform, increased research and funding to this critical area. We aim to accentuate the importance of a blue economy in establishing carbon-neutral markets and effective climate change mitigation by improving the classification, finance and governance of seaweed ecosystem services.

A relational turn in climate change adaptation: Evidence from urban nature-based solutions.

Ambio [Epub ahead of print].

The emergence of nature-based solutions (NbS) in science, policy, and practice signals a paradigmatic shift in urban climate change adaptation, yet empirical investigations into its impact on adaptation definitions and progress tracking remain scarce. Addressing this gap, we conducted thematic analysis on semi-structured interviews (n = 15) with practitioners responsible for implementing and evaluating urban NbS in different countries. We provide a nuanced understanding of urban adaptation goals within urban NbS according to the insights from these practitioners, extending beyond hazard mitigation and towards cultivating and strengthening relationships between humans and nature. Tracking adaptation progress towards such relational adaptation goals requires acknowledging knowledge pluralism and the diversity of human-nature relations. We propose an alternative definition of adaptation supported by our data that aims to foster a more holistic approach to urban climate adaptation that accounts for the potential benefits of urban NbS across interconnected climate, biodiversity, and social goals.

A modelling framework to analyze climate change effects on radionuclide aquifer contamination.

Journal of contaminant hydrology, 269:104470 pii:S0169-7722(24)00174-8 [Epub ahead of print].

Non-stationarity of climatic variables (e.g., temperature and precipitation) due to Climate Change (CC) can affect the migration processes of radionuclides released from nuclear activities. In this paper, a framework of analysis is developed to predict the evolution in time of contaminant concentration and fluence under different Climatic Boundary Conditions (CBCs) of precipitation scenarios provided by a climate model integrated with an accurate physical coupled hydraulic-transport model. A case study is worked out with respect to the migration of a radioactive contaminant ([232]Th) at Kirtland Air Force Base (Albuquerque, New Mexico, USA), for which the different CBCs considered are: i) stationary and ii) non-stationary precipitation. The effects of such alternative hypotheses on the physical modelling results are analysed, using a cross-wavelet analysis. It is shown that fluence is strongly affected by precipitation extremes, more than concentration, and it is claimed that a daily scale on the information and data of CBCs is necessary to model, with sufficient accuracy, the migration process and properly assess the impact of future CC on groundwater contamination.

Climate Change and Emerging Infectious Diseases: A Precarious Relationship.

AACN advanced critical care, 35(4):325-333.

Climate change is apparent. Temperatures are rising. Floods are more frequent and devastating. Climate changes can favor the development of emerging infectious diseases. The number of animal reservoirs and vector hosts can increase, further spreading pathogens. Many emerging infectious diseases were not historically considered major threats in US but have become a major concern in US territories and various states. In June 2024, the Centers for Disease Control and Prevention issued a Health Alert Network advisory about an increase in local transmission of dengue fever. Preventing the transmission of emerging infectious diseases has become a focus of regulatory agencies. Nurse education at all levels should include infectious diseases and be coordinated with local, state, and regional institutions. Emerging infectious diseases are now formidable challenges to health care.

Developing a Green Nursing Practice in a Profession That Contributes to Climate Change: One Nurse's Journey.

AACN advanced critical care, 35(4):310-319.

The health care industry accounts for 5% of global greenhouse gas emissions, with hospitals being the largest contributor. Critical care units create 3 times the greenhouse emissions of other hospital patient care units. Health care contributions to environmental harm include medical waste disposal, toxicant exposure, and pollutants. Integrating green practices into hospitals, especially in intensive care units, can seem overwhelming, with barriers including time constraints, lack of leadership and organizational support, and ignorance of green practices. Nursing is a socially responsible discipline committed to improving the health of individuals and communities; values of environmental stewardship and the desire to minimize poor health outcomes caused by climate change do not always align with hospital policies or clinician practices. This article addresses how nurses can confront the complex environmental problems in the workplace, apply sustainability principles to develop a green nursing practice, and collectively influence the future of national and global health.

Investigating the Bromoform Membrane Interactions Using Atomistic Simulations and Machine Learning: Implications for Climate Change Mitigation.

The journal of physical chemistry. B [Epub ahead of print].

Methane emissions from livestock contribute to global warming. Seaweeds used as food additive offer a promising emission mitigation strategy because seaweeds are enriched in bromoform─a methanogenesis inhibitor. Therefore, understanding bromoform storage and production in seaweeds and particularly in a cell-like environment is crucial. As a first step toward this aim, we present an atomistic description of bromoform dynamics, diffusion, and aggregation in the presence of lipid membranes. Using all-atom molecular dynamics simulations with customized CHARMM-formatted bromoform force field files, we investigate the interactions of bromoform and lipid bilayer across various concentrations. Bromoform penetrates membranes and at high concentrations forms aggregates outside the membrane without affecting membrane thickness or lipid tail order. Aggregates outside the membrane influence the membrane curvature. Within the membrane, bromoform preferentially localizes in the membrane hydrophobic core and diffuses the slowest along the membrane normal. Employing general local-atomic descriptors and unsupervised machine learning, we demonstrate the similarity of bromoform local structures between the liquid and aggregated forms.

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.

Papers in Classical Genetics

The ESP began as an effort to share a handful of key papers from the early days of classical genetics. Now the collection has grown to include hundreds of papers, in full-text format.

Digital Books

Along with papers on classical genetics, ESP offers a collection of full-text digital books, including many works by Darwin and even a collection of poetry — Chicago Poems by Carl Sandburg.

Timelines

ESP now offers a large collection of user-selected side-by-side timelines (e.g., all science vs. all other categories, or arts and culture vs. world history), designed to provide a comparative context for appreciating world events.

Biographies

Biographical information about many key scientists (e.g., Walter Sutton).

Selected Bibliographies

Bibliographies on several topics of potential interest to the ESP community are automatically maintained and generated on the ESP site.
