The Lancet Countdown on health and climate change: from 25 years of inaction to a global transformation for public health

Beyond the Slogans: Understanding the Ecological Consciousness of Nurses to Advance Ecological Knowledge and Practice

Despite unprecedented global environmental changes with widespread health effects, and rapid advances in nursing knowledge and education, the concept of environment within the discipline remains restricted. Environmental health continues to be marginalized in nursing education and practice, with nurses struggling to get beyond the slogans to arrive at practical applications. Framed by ecohealth and radical ecopsychology theory (concerned with nature connection, individual wellness, and social/earth justice), this study employed an online survey (n = 40) with thematic content analysis. The study explored factors that influenced eco-consciousness, how it affected nursing work, and how it was integrated into practice The 40 participants from 3 Canadian provinces included 32 nurses employed in education and clinical practice and 8 student nurses. Three main themes emerged: awakening consciousness, challenges in the discipline and profession, and finding opportunities. In particular, the students expressed a need for early integration of environmental health teaching into curriculum. Results illustrate an ongoing knowledge-practice gap and highlight the frustration and dismay of nurses whose efforts remain marginalized. Motivations and opportunities for nurses to undertake an expanded role in adopting environmental health as central to the discipline and practice of nursing can and must be more intently harnessed. As curricular approaches are expanded, further inquiry is proposed into the role of both early experiences and nursing education to transform the response to the ecological crises of our times.

'12 tips for teaching environmental sustainability to health professionals'

Background: As recognition of the health impacts of climate change and other environmental challenges increases, so too does the need for health care professionals to practice healthcare sustainably. Environmental sustainability in healthcare extends beyond our traditional understanding of environmental health, which is often limited to environmental hazards and disease. Health services, professional organizations, and training institutions are increasingly forming climate and sustainability position statements and policies accordingly. To prepare future health professionals for global environmental change, environmental sustainability must be meaningfully integrated into health curricula.Aim: To provide educators with 12 tips for integrating environmental sustainability into health professional education.Methods: The authors reviewed the literature relating to climate change, environmental sustainability and health, and health professional education. By combining findings from this search with reflections on their own experience in clinical and public health teaching across nursing and midwifery, paramedicine, medicine, and public health, the authors developed recommendations for integrating environmental sustainability into health professional education.Results: These 12 tips can be used to teach students and qualified health professionals in nursing, allied health, and medicine to practice healthcare in an environmentally sustainable manner.Conclusions: Empowering health professionals to practice environmentally sustainable healthcare has economic, social, health, and environmental benefits. Teaching environmental sustainability to health professionals enhances existing learning by updating curricula with the latest evidence of how environmental determinants of health are rapidly changing and enables both educators and students to make an important contribution to safeguarding human health, the environment, and healthcare for future generations.

Recent advances in the pretreatment of microalgal and lignocellulosic biomass: A comprehensive review

Microalgal and lignocellulosic biomass is the most sumptuous renewable bioresource raw material existing on earth. Recently, the bioconversion of biomass into biofuels have received significant attention replacing fossil fuels. Pretreatment of biomass is a critical process in the conversion due to the nature and structure of the biomass cell wall that is complex. Although green technologies for biofuel production are advancing, the productivity and yield from these techniques are low. Over the past years, various pretreatment techniques have been developed and successfully employed to improve the technology. This paper presents an in-depth review of the recent advancement of pretreatment methods focusing on microalgal and lignocellulosic biomass. The technological approaches involving physical, chemical, biological and other latest pretreatment methods are reviewed.

The effects of household's climate-related displacement on delivery and postnatal care service utilization in rural Bangladesh

Exposure to extreme climate events causes population displacement and adversely affects the health of mothers and children in multiple ways. This paper investigates the effects of displacement on whether a child is delivered at a health center, as opposed to at home, and on postnatal care service utilization in Bangladesh. Using cross-sectional survey data from 599 mothers who gave birth in the three years prior to the date of interview, including 278 from households which had previously been displaced and 231 from households which had not been displaced, we use multivariate logistic regression to identify the factors associated with maternal healthcare service utilization. The results show that displaced households' mothers are only about a quarter as likely to deliver at a health center as mothers from non-displaced households. The use of health center-based delivery decreases as the numbers of past displacements increases. Higher number of previous children, lower use of antenatal care during pregnancy, lower household income, and lack of access to radio/television also significantly reduce a mother's likelihood of delivery at a health center. Displaced mothers are also substantially less likely to use postnatal care services for their neonates, especially those supplied by trained providers. Use of health facilities for delivery, use of antenatal care services, and previous number of children are other important predictors of postnatal care service utilization for neonates. In light of these findings, relocation of local health facilities with basic and emergency care provisions to areas in which the displaced have resettled, reinforcement of Family Planning services, and extension of coverage of the Maternity Allowance benefits in the displacement-prone mainland riverine areas are recommended policy responses.

Revisiting the Psychology of Denial Concerning Low-Carbon Behaviors: From Moral Disengagement to Generating Social Change

This paper reassesses the scope for shifting high-carbon personal behaviors in the light of prevailing insufficient political and regulatory action. Our previous research has shown that citizens regard such behavioral shifts as extremely daunting and create a number of psychological denial mechanisms that draw attention to the inaction of others, including governments. Further theoretical insights and relevant new findings have been attained from a more recent survey of more than 1000 German residents. This reveals that direct denial of anthropogenic climate change is replaced by a denial of responsibility for individual climate action. Ways of moral disengagement play a more dominant role, such as the diffusion and displacement of responsibility, although a majority is aware of—and very much concerned about—the climate crisis. More attention needs to be given for further reinterpretation of the role of moral disengagement to single out adequate strategies for different individuals and groups of people, such as making role models more visible to encourage social learning that could accelerate further necessary moral and behavioral transformations.

The effects of climate change on human health in Africa, a dermatologic perspective: a report from the International Society of Dermatology Climate Change Committee

Throughout much of the African continent, healthcare systems are already strained in their efforts to meet the needs of a growing population using limited resources. Climate change threatens to undermine many of the public health gains that have been made in this region in the last several decades via multiple mechanisms, including malnutrition secondary to drought-induced food insecurity, mass human displacement from newly uninhabitable areas, exacerbation of environmentally sensitive chronic diseases, and enhanced viability of pathogenic microbes and their vectors. We reviewed the literature describing the various direct and indirect effects of climate change on diseases with cutaneous manifestations in Africa. We included non-communicable diseases such as malignancies (non-melanoma skin cancers), inflammatory dermatoses (i.e. photosensitive dermatoses, atopic dermatitis), and trauma (skin injury), as well as communicable diseases and neglected tropical diseases. Physicians should be aware of the ways in which climate change threatens human health in low- and middle-income countries in general, and particularly in countries throughout Africa, the world's lowest-income and second most populous continent.

Climate changes reproductive and children's health: a review of risks, exposures, and impacts

Our climate has significantly changed, exceeding what the world has experienced over the last 650,000 years, and has been cited as the most significant health threat of the twenty-first century. Climate change is impacting health in unprecedented ways. While everyone is vulnerable to the health impacts associated with climate change, children are disproportionately affected because of their physical and cognitive immaturity. Climate change impacts that include rising temperatures, extreme weather, rising sea levels, and increasing carbon dioxide levels are associated with a wide range of health issues in children such as asthma, allergies, vector-borne diseases, malnutrition, low birth weight, and post-traumatic stress disorder. Pediatric health providers play a critical role in advancing the science and translating findings to improve public understanding about the link between climate changes and children's health, and establishing strategies to address these issues. This review will provide an overview of research exploring the impact of climate change on children's health impacts, as well as provide recommendations for pediatric research moving forward.

The PULSE Project: A Case of Use of Big Data Uses Toward a Cohomprensive Health Vision of City Well Being

Despite the silent effects sometimes hidden to the major audience, air pollution is becoming one of the most impactful threat to global health. Cities are the places where deaths due to air pollution are concentrated most.

In order to correctly address intervention and prevention thus is essential to assest the risk and the impacts of air pollution spatially and temporally inside the urban spaces. PULSE aims to design and build a large-scale data management system enabling real time analytics of health, behaviour and environmental data on air quality. The objective is to reduce the environmental and behavioral risk of chronic disease incidence to allow timely and evidence-driven management of epidemiological episodes linked in particular to two pathologies; asthma and type 2 diabetes in adult populations. developing a policy-making across the domains of health, environment, transport, planning in the PULSE test bed cities.

Risk Analysis of Air Pollution and Meteorological Factors Affecting the Incidence of Diabetes in the Elderly Population in Northern China

BACKGROUND

Research investigating the effect of air pollution on diabetes incidence is mostly conducted in Europe and the United States and often produces conflicting results. The link between meteorological factors and diabetes incidence remains to be explored. We aimed to explore associations between air pollution and diabetes incidence and to estimate the nonlinear and lag effects of meteorological factors on diabetes incidence.

METHODS

Our study included 19,000 people aged ≥60 years from the Binhai New District without diabetes at baseline. The generalized additive model (GAM) and the distributed lag nonlinear model (DLNM) were used to explore the effect of air pollutants and meteorological factors on the incidence of diabetes. In the model combining the GAM and DLNM, the impact of each factor (delayed by 30 days) was first observed separately to select statistically significant factors, which were then incorporated into the final multivariate model. The association between air pollution and the incidence of diabetes was assessed in subgroups based on age, sex, and body mass index (BMI).

RESULTS

We found that cumulative RRs for diabetes incidence were 1.026 (1.011-1.040), 1.019 (1.012-1.026), and 1.051 (1.019-1.083) per 10 μg/m³ increase in PM_2.5, PM₁₀, and NO₂, respectively, as well as 1.156 (1.058-1.264) per 1 mg/m³ increase in CO in a single-pollutant model. Increased temperature, excessive humidity or dryness, and shortened sunshine duration were positively correlated with the incidence of diabetes in single-factor models. After adjusting for temperature, humidity, and sunshine, the risk of diabetes increased by 9.2% (95% confidence interval (CI):2.1%-16.8%) per 10 μg/m³ increase in PM_2.5. We also found that women, the elderly (≥75 years), and obese subjects were more susceptible to the effect of PM_2.5.

CONCLUSION

Our data suggest that PM_2.5 is positively correlated with the incidence of diabetes in the elderly, and the relationship between various meteorological factors and diabetes in the elderly is nonlinear.

Hospital climate actions and assessment tools: a scoping review protocol

INTRODUCTION

Health and climate change are inexorably linked through the exacerbation of health risks and the contribution of the health sector to greenhouse gas emissions. Climate action in healthcare settings is critical to reduce risks and impacts of climate change through the smarter use of energy, minimising waste and enhancing disaster preparedness. Globally, hospital climate action is growing; however, the potential for further progress and impacts remains. The literature on this topic lacks synthesis, and this poses challenges for hospital leadership in tracking the impact of climate action. This scoping review will summarise the current knowledge about hospital climate action and existing tools to measure progress in this area.

METHODS AND ANALYSIS

This scoping review will be conducted applying the six-stage protocol proposed by Arksey and O'Malley. The study includes literature of how hospitals have addressed climate change (mitigation and adaptation) since the Kyoto Protocol was signed in 1997. All identified studies indexed in Medline, Scopus, Embase and CINAHL will be examined. The search strategy will also include Google Scholar to capture relevant grey literature. Quantitative and thematic analysis will be used to evaluate and categorise the study results.

ETHICS AND DISSEMINATION

This scoping review is part of the climate-smart healthcare initiative which will provide a valuable synthesis to aid understanding of hospitals' climate actions, and tools used to measure its implementation. As such it will contribute to mobilising and accelerating the implementation of climate action in hospitals. The findings will be disseminated with all members of the International Health Promoting Hospital and Health Services (HPH) and the Global Green and Healthy Hospital network. Dissemination will occur through peer-reviewed publications; and with the HPH and GGHH members through its annual conference and newsletter.

Advancing a School of Nursing Center for Climate Change, Climate Justice, and Health

This chapter addresses the development and advancement of the Center for Climate Change, Climate Justice, and Health (CCCCJH) in the School of Nursing at the MGH Institute of Health Professions, the first nurse-led center emerged from the overwhelming evidence of climate change and its associated deleterious health consequences. The Center steering committee developed a mission, vision, and core values as well as a logo to guide the first year of initiatives and galvanize the efforts for the future. Workshop and symposium development, implementation, and evaluation are discussed. Future directions and the importance of educational initiatives aimed at expanding nursing and interprofessional knowledge of the intersection of climate and health are discussed.

Outrage and the emotional labour associated with environmental activism among nurses

AIM

To investigate the emotions associated with environmental activism among nurses.

BACKGROUND

Nursing has a long history of political activism in relation to social justice issues. Some nurses are environmental activists.

DESIGN

Ethnography.

METHODS

Focus groups and individual interviews were triangulated with additional observational data. The 40 participants (USA = 23, UK = 17) were nurses actively engaged with environmental/sustainability issues. Data collection was from March-October 2017. Data were analysed using discourse analysis.

RESULTS

The trigger for nurses' environmental activism was a strong emotional response to recognizing risks to human health. Their activism results in an additional emotion burden above which they routinely experience in caring for patients. Many feel over-whelmed by the magnitude of the issues. Nurses in America feel more supported and empowered to be activists than UK nurses.

CONCLUSION

This study reveals for the first time that advocating for the environment is emotional labour, additional to the previously recognized emotional labour associated with caring for patients. Encouragement and support from others, particularly fellow nurses, helps nurse environmental activists continue to fight for the health of communities and the planet.

IMPACT

Outrage at threats to human health triggers nurses' environmental activism. Environmental activism creates an additional emotional burden above that routinely experienced in caring for patients. Nurses in America feel more supported and empowered to be activists than UK. Nurses whose practice embraces environmental activism need practical and emotional support from other nurses.

Air Pollution and Health - A Science-Policy Initiative

Air pollution is a major, preventable and manageable threat to people's health, well-being and the fulfillment of sustainable development. Air pollution is estimated to contribute to at least 5 million premature deaths each year across the world. No one remains unaffected by dirty air, but the adverse impacts of air pollution fall most heavily upon vulnerable populations, such as children, women, and people living in poverty - groups to whom States have special obligations under international human rights law. The National Academies of Sciences and Medicine of South Africa, Brazil, Germany and the United States of America are calling upon government leaders, business and citizens to take urgent action on reducing air pollution throughout the world - to the benefit of human health and well-being, to the benefit of the environment and as a condition towards sustainable development. Air pollution is a cross-cutting aspect of many UN Sustainable Development Goals.

Commentary - The Climate Change and Health Adaptation Program: Indigenous Climate Leaders' Championing Adaptation Effort

The Climate Change and Health Adaptation Program (CCHAP) is a program within the First Nations Inuit Health Branch of Indigenous Services Canada (which was previously under the responsibility of Health Canada). The CCHAP supports Inuit and First Nation communities in mitigating and adapting to the health impacts of climate change. The impacts of climate change on Indigenous health can be observed in multiple areas including, but not limited to, food security, cultural medicines, mental health and landbased practices. This program seeks to address the needs of climate change and health in First Nation and Inuit communities to support resiliency and adaptation to a changing climate both now and in the future through its emphasis on youth and capacity building. The commentary is based on the Program's eleven years of experience working with and for Indigenous communities and provides an overview of the CCHAP model and the work it has and continues to support. This paper demonstrates three examples of community-based projects to mitigate and adapt to the health impacts of climate change to demonstrate climate change resiliency within Indigenous communities.

The 2019 report of the MJA-Lancet Countdown on health and climate change: a turbulent year with mixed progress

The MJA-Lancet Countdown on health and climate change was established in 2017 and produced its first Australian national assessment in 2018. It examined 41 indicators across five broad domains: climate change impacts, exposures and vulnerability; adaptation, planning and resilience for health; mitigation actions and health co-benefits; economics and finance; and public and political engagement. It found that, overall, Australia is vulnerable to the impacts of climate change on health, and that policy inaction in this regard threatens Australian lives. In this report we present the 2019 update. We track progress on health and climate change in Australia across the same five broad domains and many of the same indicators as in 2018. A number of new indicators are introduced this year, including one focused on wildfire exposure, and another on engagement in health and climate change in the corporate sector. Several of the previously reported indicators are not included this year, either due to their discontinuation by the parent project, the Lancet Countdown, or because insufficient new data were available for us to meaningfully provide an update to the indicator. In a year marked by an Australian federal election in which climate change featured prominently, we find mixed progress on health and climate change in this country. There has been progress in renewable energy generation, including substantial employment increases in this sector. There has also been some progress at state and local government level. However, there continues to be no engagement on health and climate change in the Australian federal Parliament, and Australia performs poorly across many of the indicators in comparison to other developed countries; for example, it is one of the world's largest net exporters of coal and its electricity generation from low carbon sources is low. We also find significantly increasing exposure of Australians to heatwaves and, in most states and territories, continuing elevated suicide rates at higher temperatures. We conclude that Australia remains at significant risk of declines in health due to climate change, and that substantial and sustained national action is urgently required in order to prevent this.

Incorporating Health Outcomes into Land-Use Planning

The global trend toward increased agricultural production puts pressure on undeveloped areas, raising the question of how to optimally allocate land. Land-use change has recently been linked to a number of human health outcomes, but these are not routinely considered in land-use decision making. We review examples of planners' currently used strategies to evaluate land use and present a conceptual model of optimal land use that incorporates health outcomes. We then present a framework for evaluating the health outcomes of land-use scenarios that can be used by decision makers in an integrated approach to land-use planning.

How do foodservice dietitians and dietetic students learn about environmental sustainability? A scoping review protocol

INTRODUCTION

Healthcare services are responsible for 7% of Australia's carbon emissions, or 35 772 kt per annum, with 44% of these attributed to hospitals and an unknown proportion originating from the kitchen. Carbon emissions contribute to climate change that is predicted to adversely impact health outcomes. Healthcare professionals and institutions have an opportunity to reduce their impact on the climate. Australian dietitians, however, are not required to learn about environmental sustainability during their tertiary education. This scoping review will identify pedagogical frameworks employed by educational institutions and providers of professional development, to describe how foodservice dietitians and dietetic students develop environmental sustainability capabilities.

METHODS AND ANALYSIS

The scoping review methodology established by Arksey and O'Malley will be used for this review. Papers will be included if they focus on dietitians or dietetic students learning about environmental sustainability in the foodservice domain. Nine databases, Business Source Complete, CINAHL, Cochrane, Edge (via informit), EMBASE, MEDLINE, Proquest, Scopus and Web of Science, will be searched from their inception. Grey literature will also be identified by searching theses databases, professional bodies databases and Google Scholar. Eligible articles will be identified by screening papers by their title and abstract, followed by a full-text review. The study selection process will be completed independently by the primary investigator and the research team. Any discrepancies will be resolved through discussion. The extracted data including citation information, information on the intervention and outcomes will be summarised using descriptive statistics. Themes describing the pedagogical underpinnings of the interventions, the measurement tools and the impact of the learning activities will be synthesised narratively.

ETHICS AND DISSEMINATION

The results will inform the development of evidence-based pedagogical frameworks to enhance the capabilities of foodservice dietitians and dietetic students in environmental sustainability. Dissemination will occur through conference presentations, peer-reviewed journals and distribution through national accrediting bodies.

Long-Term Public Health Responses in High-Impact Weather Events: Hurricane Maria and Puerto Rico as a Case Study

This statement responds to the public health challenges in Puerto Rico in the wake of Hurricane Maria during September 2017. As a result of Maria, and to a certain extent Hurricane Irma, the territory sustained unprecedented damage. We call for a mid- and long-term public health response and research to assess the long-term impacts of high-impact weather events, such as Maria's effects on Puerto Rico, including impacts on vulnerable populations' environmental health and well-being.

When Both Markets and Governments Fail Health

This paper presents the rationale and motivation for countries and the global development community to tackle a critical set of functions in the health sector that appear to be under-prioritized and underfunded. The recent eruptions of Ebola outbreaks in Africa and other communicable diseases like Zika and SARS elsewhere led scientific and medical commissions to call for global action. The calls for action motivated the World Health Organization (WHO) to respond by defining a new construct within the health sector: Common Good for Health (CGH). While the starting point for developing the CGH construct was the re-emergence of communicable diseases, it extends to additional outcomes resulting from failures to act and finance within and outside the health sector. This paper summarizes global evidence on failures to address CGHs effectively, identifies potential reasons for the public and private sectors' failures to respond, and lays out the first phase of the WHO program as represented by the papers in this special issue of Health Systems & Reform.

Why be sustainable? The Australian and New Zealand College of Anaesthetists Professional Document PS64: Statement on Environmental Sustainability in Anaesthesia and Pain Medicine Practice and its accompanying background paper

Healthcare’s environmental sustainability is increasingly an area of research and advocacy focus. The Australian and New Zealand College of Anaesthetists (ANZCA) has produced a professional document, PS64, Statement on Environmental Sustainability in Anaesthesia and Pain Medicine Practice, and a background paper, PS64 BP. The purpose of the statement is to affirm ANZCA’s commitment to environmental sustainability and support anaesthetists in promoting environmentally sustainable work practices. This article presents the main features of PS64 and its background paper, and the associated supporting evidence. The healthcare sector is highly interconnected with activities that emit pollution to air, water and soils, considerably adding to humanity’s collective ecological footprint. As anaesthetists, we are uniquely high-carbon doctors due to our work anaesthetising with greenhouse gases (particularly desflurane and nitrous oxide) and our exposure and contribution to large amounts of resource and energy use and waste generation in operating theatres. Discussion is made of the improving research base of anaesthetic life-cycle assessments—that is, cradle-to-grave studies of how much energy, water and so on a product or process requires throughout its entire life. Thereafter, reducing, reusing and recycling as well as water use are examined. Ongoing research efforts within environmentally sustainable anaesthesia are highlighted. Environmentally sustainable anaesthesia requires scholarship, health advocacy, leadership, communication and collaboration. The focus is placed on practical initiatives within PS64 and the background paper that can be achieved by all anaesthetists striving towards more sustainable healthcare practices that reduce waste, reap financial benefits and improve health.

The (in)visible health risks of climate change

This paper scrutinizes the assertion that knowledge gaps concerning health risks from climate change are unjust, and must be addressed, because they hinder evidence-led interventions to protect vulnerable populations. First, we construct a taxonomy of six inter-related forms of invisibility (social marginalization, forced invisibility by migrants, spatial marginalization, neglected diseases, mental health, uneven climatic monitoring and forecasting) which underlie systematic biases in current understanding of these risks in Latin America, and advocate an approach to climate-health research that draws on intersectionality theory to address these inter-relations. We propose that these invisibilities should be understood as outcomes of structural imbalances in power and resources rather than as haphazard blindspots in scientific and state knowledge. Our thesis, drawing on theories of governmentality, is that context-dependent tensions condition whether or not benefits of making vulnerable populations legible to the state outweigh costs. To be seen is to be politically counted and eligible for rights, yet evidence demonstrates the perils of visibility to disempowered people. For example, flood-relief efforts in remote Amazonia expose marginalized urban river-dwellers to the traumatic prospect of forced relocation and social and economic upheaval. Finally, drawing on research on citizenship in post-colonial settings, we conceptualize climate change as an 'open moment' of political rupture, and propose strategies of social accountability, empowerment and trans-disciplinary research which encourage the marginalized to reach out for greater power. These achievements could reduce drawbacks of state legibility and facilitate socially-just governmental action on climate change adaptation that promotes health for all.

Early Biological Aging and Fetal Exposure to High and Low Ambient Temperature: A Birth Cohort Study

BACKGROUND

Although studies have provided estimates of premature mortality to either heat or cold in adult populations, and fetal exposure to ambient temperature may be associated with life expectancy, the effects of temperature on aging in early life have not yet been studied. Telomere length (TL) is a marker of biological aging, and a short TL at birth may predict lifespan and disease susceptibility later in life.

OBJECTIVES

We studied to what extent prenatal ambient temperature exposure is associated with newborn TL.

METHODS

In the ENVIRONAGE (ENVIRonmental influence ON early AGEing) birth cohort in Flanders, Belgium, we measured cord blood and placental TL in 1,103 mother-newborn pairs (singletons with ≥36wk of gestation) using a quantitative real-time polymerase chain reaction (qPCR) method. We associated newborn TL with average weekly exposure to ambient temperature using distributed lag nonlinear models (DLNMs) while controlling for potential confounders. Double-threshold DLNMs were used to estimate cold and heat thresholds and the linear associations between temperature and TL below the cold threshold and above the heat threshold.

RESULTS

Prenatal temperature exposure above the heat threshold (19.5°C) was associated with shorter cord blood TL. The association with a 1°C increase in temperature was strongest at week 36 of gestation and resulted in a 3.29% [95% confidence interval (CI): -4.67, -1.88] shorter cord blood TL. Consistently, prenatal temperature exposure below the cold threshold (5.0°C) was associated with longer cord blood TL. The association with a 1°C decrease in temperature was strongest at week 10 of gestation with 0.72% (95% CI: 0.46, 0.97) longer cord blood TL.

DISCUSSION

Our study supports potential effects of prenatal temperature exposure on longevity and disease susceptibility later in life. Future climate scenarios might jeopardize the potential molecular longevity of future generations from birth onward. https://doi.org/10.1289/EHP5153.

Perceptions of Mental Health and Wellbeing Following Residential Displacement and Damage from the 2018 St. John River Flood

Climate change has spurred an increase in the prevalence and severity of natural disasters. Damage from natural disasters can lead to residential instability, which negatively impacts mental health and wellbeing. However, research on the mental health of residents who are displaced after natural disasters is relatively novel and needs more study. This study investigates experiences of mental health in residents in New Brunswick, Canada, who experienced residential damage and/or displacement during the 2018 spring flood. Lived experiences were studied through focus groups with 20 residents and perceptions of community mental health and wellbeing were captured during key informant interviews with 10 local community leaders. Data collection and analysis employed grounded theory. Findings indicate that those who had residential displacement or damage due to the flooding experienced negative mental health impacts, both during and following the flood. While natural disasters have devastating impacts on mental health, the data also indicate that the communities were positively impacted by a collective and collaborative response to the flood. This paper argues for the utility of communal coping as a concept to describe the experiences of communities following residential damage and/or displacement following natural disasters.

Nexus between Climate Change, Displacement and Conflict: Afghanistan Case

The character, the motion and the proportion of environment-induced migration have radically changed in recent years. Environment-induced migration is an increasingly recognized fact and has become one of the main challenges of the 21st century, and needs to be focused on to ensure sustainable growth. This new stance is due to the changing character of environmental degradation. Global environmental issues, including climate change, loss of biodiversity, river and oceanic contamination, land degradation, drought, and the destruction of rainforests, are progressively stressing the earth’s ecosystems. Among these issues, climate change is one of the most severe threats. Climate change alone does not directly induce people to move but it generates harmful environmental effects and worsens present vulnerabilities. The current study aims to provide cornerstone links between the effects of climate change, migration decisions, displacement risk and conflicts in the example of Afghanistan, as a country that is extremely affected by both climate change and conflicts, and outline priority policy focuses to mitigate the current situation in the country.

The association between heat exposure and hospitalization for undernutrition in Brazil during 2000-2015: A nationwide case-crossover study

BACKGROUND

Global warming is predicted to indirectly result in more undernutrition by threatening crop production. Whether temperature rise could affect undernutrition directly is unknown. We aim to quantify the relationship between short-term heat exposure and risk of hospitalization due to undernutrition in Brazil.

METHODS AND FINDINGS

We collected hospitalization and weather data for the hot season (the 4 adjacent hottest months for each city) from 1,814 Brazilian cities during 1 January 2000-31 December 2015. We used a time-stratified case-crossover design to quantify the association between heat exposure and hospitalization due to undernutrition. Region-specific odds ratios (ORs) were used to calculate the attributable fractions (AFs). A total of 238,320 hospitalizations for undernutrition were recorded during the 2000-2015 hot seasons. Every 1°C increase in daily mean temperature was associated with a 2.5% (OR 1.025, 95% CI 1.020-1.030, p < 0.001) increase in hospitalizations for undernutrition across lag 0-7 days. The association was greatest for individuals aged ≥80 years (OR 1.046, 95% CI 1.034-1.059, p < 0.001), 0-4 years (OR 1.039, 95% CI 1.024-1.055, p < 0.001), and 5-19 years (OR 1.042, 95% CI 1.015-1.069, p = 0.002). Assuming a causal relationship, we estimate that 15.6% of undernutrition hospitalizations could be attributed to heat exposure during the study period. The AF grew from 14.1% to 17.5% with a 1.1°C increase in mean temperature from 2000 to 2015. The main limitations of this study are misclassification of different types of undernutrition, lack of individual temperature exposure data, and being unable to adjust for relative humidity.

CONCLUSIONS

Our study suggests that global warming might directly increase undernutrition morbidity, by a route other than by threatening food security. This short-term effect is increasingly important with global warming. Global strategies addressing the syndemic of climate change and undernutrition should focus not only on food systems, but also on the prevention of heat exposure.

Environmental health in Australia: overlooked and underrated

Improvements in environmental health have had the most significant impact on health status. In Australia, life expectancy has significantly increased through provision of vaccination, safe food and drinking water, appropriate sewage disposal and other environmental health measures. Yet the profession that is instrumental in delivering environmental health services at the local community level is overlooked. Rarely featuring in mainstream media, the successes of Environmental Health Officers (EHOs) are invisible to the general public. As a consequence, students entering university are unaware of the profession and its significant role in society. This has resulted in there being too few EHOs to meet the current regulatory requirements, much less deal with the emerging environmental health issues arising as a consequence of changing global conditions including climate change. To futureproof Australian society and public health this workforce issue, and the associated oversight of environmental health must be addressed now.

Ambient temperature and mortality due to acute myocardial infarction in Brazil: an ecological study of time-series analyses

Ambient temperature may lead to decompensation of cardiovascular diseases and deaths by acute myocardial infarction (AMI). Little is known about this relationship in South American countries located in regions of a hot climate. This study aims to investigate the effects of ambient temperature on mortality due to AMI in six Brazilian micro-regions, which present different climates. We analyzed daily records of deaths by AMI between 1996 and 2013. We estimated the accumulate relative and attributable risks with lags of up to 14 days, using distributed non-linear lag model. Micro-regions that were closest to the equator did not show an association between temperature and mortality. The lowest risk temperatures varied between 22 °C and 28 °C, in the Southern region of Brazil and the Midwest region, respectively. Low temperatures associated with the highest mortality risk were observed in the same areas, varying between 5 °C and 15 °C. The number of deaths attributed to cold temperatures varied from 176/year in Brasilia to 661/year in São Paulo and those deaths attributed to hot temperatures in Rio de Janeiro amounted to 115/year. We showed the relative risk and the attributable risk of warmer and colder days in tropical regions. The estimate of the number of deaths due to climate, varying according to each area, is a way of bringing information to those responsible for health policies based on easily-understood measurements.

[Climate change and its significance in the healthcare community: history, landmarks, and major players]

Since the early 1990s, science has addressed anthropogenic climate change as a health issue. From about 2000 onwards, the scientific literature and evidence on the health effects of climate change has been rapidly increasing. Global warming is now considered an "existential threat to humankind," and leading health organizations call climate change "the defining issue for public health in the 21 century" or a "public health emergency."In recent years, climate change as a health issue has become more and more prominent in health communities on the national and international level.The growing importance of this issue in the international health community and the stages, milestones, and topics of this development are described and what health professionals and health organizations can do to protect health from climate change is demonstrated. The decisive role of The Lancet and the reports of its international commissions, the British Medical Journal (BMJ), and the World Health Organisation (WHO) in setting the agenda is underlined. Important actors, organizations, initiatives as well as new concepts like "planetary health" and "planetary boundaries" are introduced. In the German health sector, however, climate change - apart from niches - has not been much of an issue so far. Neither in the health sector, climate policies, nor climate movement the connections between climate change and health are sufficiently understood, considered, or implemented. A look beyond borders shows what might be possible and necessary in view of the possibly "greatest crisis we have ever faced."The article is based on the author's experience, cooperation, and exchange with parties that are engaged with the issue and on years of literature research. He initiated the campaign of German doctors calling on their pension funds to divest from fossil fuels and is a founding and present board member of the "German Alliance on Health and Climate Change," which was founded 2017.

Integrating Public Health into Climate Change Policy and Planning: State of Practice Update

Policy action in the coming decade will be crucial to achieving globally agreed upon goals to decarbonize the economy and build resilience to a warmer, more extreme climate. Public health has an essential role in climate planning and action: “Co-benefits” to health help underpin greenhouse gas reduction strategies, while safeguarding health—particularly of the most vulnerable—is a frontline local adaptation goal. Using the structure of the core functions and essential services (CFES), we reviewed the literature documenting the evolution of public health’s role in climate change action since the 2009 launch of the US CDC Climate and Health Program. We found that the public health response to climate change has been promising in the area of assessment (monitoring climate hazards, diagnosing health status, assessing vulnerability); mixed in the area of policy development (mobilizing partnerships, mitigation and adaptation activities); and relatively weak in assurance (communication, workforce development and evaluation). We suggest that the CFES model remains important, but is not aligned with three concepts—governance, implementation and adjustment—that have taken on increasing importance. Adding these concepts to the model can help ensure that public health fulfills its potential as a proactive partner fully integrated into climate policy planning and action in the coming decade.

The effect of global change on mosquito-borne disease

More than 80% of the global population is at risk of a vector-borne disease, with mosquito-borne diseases being the largest contributor to human vector-borne disease burden. Although many global processes, such as land-use and socioeconomic change, are thought to affect mosquito-borne disease dynamics, research to date has strongly focused on the role of climate change. Here, we show, through a review of contemporary modelling studies, that no consensus on how future changes in climatic conditions will impact mosquito-borne diseases exists, possibly due to interacting effects of other global change processes, which are often excluded from analyses. We conclude that research should not focus solely on the role of climate change but instead consider growing evidence for additional factors that modulate disease risk. Furthermore, future research should adopt new technologies, including developments in remote sensing and system dynamics modelling techniques, to enable a better understanding and mitigation of mosquito-borne diseases in a changing world.

Estimating the Health-Related Costs of 10 Climate-Sensitive U.S. Events During 2012

Climate change threatens human health, but there remains a lack of evidence on the economic toll of climate-sensitive public health impacts. We characterize human mortality and morbidity costs associated with 10 climate-sensitive case study events spanning 11 US states in 2012: wildfires in Colorado and Washington, ozone air pollution in Nevada, extreme heat in Wisconsin, infectious disease outbreaks of tick-borne Lyme disease in Michigan and mosquito-borne West Nile virus in Texas, extreme weather in Ohio, impacts of Hurricane Sandy in New Jersey and New York, allergenic oak pollen in North Carolina, and harmful algal blooms on the Florida coast. Applying a consistent economic valuation approach to published studies and state estimates, we estimate total health-related costs from 917 deaths, 20,568 hospitalizations, and 17,857 emergency department visits of $10.0 billion in 2018 dollars, with a sensitivity range of $2.7-24.6 billion. Our estimates indicate that the financial burden of deaths, hospitalizations, emergency department visits, and associated medical care is a key dimension of the overall economic impact of climate-sensitive events. We found that mortality costs (i.e., the value of a statistical life) of $8.4 billion exceeded morbidity costs and lost wages ($1.6 billion combined). By better characterizing health damages in economic terms, this work helps to shed light on the burden climate-sensitive events already place on U.S. public health each year. In doing so, we provide a conceptual framework for broader estimation of climate-sensitive health-related costs. The high health-related costs associated with climate-sensitive events highlight the importance of actions to mitigate climate change and adapt to its unavoidable impacts.

Business Leadership in Global Climate Change Responses

In the 2015 Paris Climate Change Agreement, 195 countries committed to reducing greenhouse gas emissions in recognition of the scientific consensus on the consequences of climate change, including substantial public health burdens. In June 2017, however, US president Donald Trump announced that the United States would not implement the Paris Agreement. We highlight the business community's backing for climate change action in the United States. Just as the US federal government is backing away from its Paris commitments, many corporate executives are recognizing the need to address the greenhouse gas emissions of their companies and the business logic of strong environmental, social, and governance practices more generally. We conclude that climate change could emerge as an issue on which the business and public health communities might align and provide leadership.

A New Integrative Theory of Brain-Body-Ecosystem Medicine: From the Hippocratic Holistic View of Medicine to Our Modern Society

Humans are increasingly aware that their fate will depend on the wisdom they apply in interacting with the ecosystem. Its health is defined as the condition in which the ecosystem can deliver and continuously renew its fundamental services. A healthy ecosystem allows optimal interactions between humans and the other biotic/abiotic components, and only in a healthy ecosystem can humans survive and efficiently reproduce. Thus, both the human and ecosystem health should be considered together in view of their interdependence. The present article suggests that this relationship could be considered starting from the Hippocrates (460 BC-370 BC) work "On Airs, Waters, and Places" to derive useful medical and philosophical implications for medicine which is indeed a topic that involves scientific as well as philosophical concepts that implicate a background broader than the human body. The brain-body-ecosystem medicine is proposed as a new more complete approach to safeguarding human health. Epidemiological data demonstrate that exploitation of the environment resulting in ecosystem damage affects human health and in several instances these diseases can be detected by modifications in the heart-brain interactions that can be diagnosed through the analysis of changes in heart rate variability.

The Nurses Climate Challenge: A National Campaign to Engage 5,000 Health Professionals Around Climate Change

Climate change poses significant threats to human health and worsens existing inequities. The health sector is a significant contributor to climate change, making up approximately 10% of U.S. greenhouse gas emissions. Yet most nurses do not learn about the health dangers of climate change in their education or in practice, and therefore are ill-equipped to lead action on climate change. When educated about climate change, nurses can effectively lead climate adaptation and mitigation strategies aimed at creating healthier populations. As the most trusted professionals and making up 40% of the health-care workforce, nurses have the potential to impact behavior change and launch a movement around climate solutions. Health Care Without Harm and the Alliance of Nurses for Healthy Environments partnered on the “Nurses Climate Challenge” with the aim of nurses educating 5,000 health professionals on climate and health. In the Nurses Climate Challenge, nurses register as Nurse Climate Champions and gain access to online resources to plan and host educational sessions about climate change. After educating, Nurse Climate Champions return to the online platform to track their progress. Within 10 months, over 540 Nurse Climate Champions from 6 continents, 16 countries, and 42 U.S. states registered for access to the resources. To date, the champions have educated over 5,250 colleagues and students about climate and health. Based on early metrics, this model of education and engagement around climate action may be applicable for other disciplines in health care and beyond.

Building Community Resilience to Mitigate Mental Health Effects of Climate Change

As global warming is taking effect, the number of natural disasters such as hurricanes, tornados, flooding, drought, and wildfires is increasing. The purpose of this article is to address the impacts of climate change on human health, using a model developed by the Centers for Disease Control and Prevention. The effects of natural disasters on mental health, and actions nurses can take to help build strong, resilient communities, are discussed in detail. Increasing awareness and building resilience will improve health outcomes. Strong social connections are a key component of community resilience. Strengthening the infrastructure of communities can mitigate the impact of climate changes.

Evidence for a link between the Atlantic Multidecadal Oscillation and annual asthma mortality rates in the US

An association between climatic conditions and asthma mortality has been widely assumed. However, it is unclear whether climatic variations have a fingerprint on asthma dynamics over long time intervals. The aim of this study is to detect a possible correlation between climatic indices, namely the Atlantic Multidecadal Oscillation and Pacific Decadal Oscillation, and asthma mortality rates over the period from 1950 to 2015 in the contiguous US. To this aim, an analysis of non-stationary and non-linear signals was performed on time series of US annual asthma mortality rates, AMO and PDO indices to search for characteristic periodicities. Results revealed that asthma death rates evaluated for four different age groups (5-14 yr; 15-24 yr; 25-34 yr; 35-44 yr) share the same pattern of fluctuation throughout the 1950-2015 time interval, but different trends, i.e. a positive (negative) trend for the two youngest (oldest) categories. Annual asthma death rates turned out to be correlated with the dynamics of the AMO, and also modulated by the PDO, sharing the same averaged ∼44 year-periodicity. The results of the current study suggest that, since climate patterns have proved to influence asthma mortality rates, they could be advisable in future studies aimed at elucidating the complex relationships between climate and asthma mortality.

Acute Myocardial Infarction Hospitalizations between Cold and Hot Seasons in an Island across Tropical and Subtropical Climate Zones-A Population-Based Study

We investigated the effects of cold and hot seasons on hospital admissions for acute myocardial infarction (AMI) at the junction of tropical and subtropical climate zones. The hospitalization data of 6897 AMI patients from January 1997 to December 2011 were obtained from the database of the National Health Insurance, including date of admission, gender, age, and comorbidities of hypertension, diabetes mellitus (DM), and dyslipidemia. A comparison of AMI prevalence between seasons and the association of season-related AMI occurrences with individual variables were assessed. AMI hospitalizations in the cold season (cold-season-AMIs) were significantly greater than those in the hot season (OR 1.15; 95% CI 1.10–1.21). In the subtropical region, cold-season-AMIs were strongly and significantly associated with the ≥65 years group (OR1.28; 95% CI 1.11 to 1.48). In the tropical region, cold-season-AMIs, in association with dyslipidemia relative to non-dyslipidemia, were significantly strong in the non-DM group (OR 1.45; 95% CI 1.01 to 2.09) but weak in the DM group (OR 0.74; 95% CI 0.55 to 0.99). The cold season shows increased risks for AMI, markedly among the ≥65 years cohort in the subtropical region, and among the patients diagnosed with either DM or dyslipidemia but not both in the tropical region. Age and comorbidity of metabolic dysfunction influence the season-related incidences of AMI in different climatic regions.

Efficient approaches to convert Coniochaeta hoffmannii lipids into biodiesel by in-situ transesterification

Coniochaeta hoffmannii was isolated from soils contaminated with biscuit factory wastes showed the maximum lipid accumulation capacity in the study. Lipid production was optimized in terms of pH, carrot pomace loading, nitrogen type and amount, incubation time. Solvent, alcohol type and catalyst concentration, dried/wet biomass concentration, reaction approaches and time were optimized for lipid extraction and transesterification. The highest lipid accumulation was found as 52.0% at pH 4 in the presence of 10% carrot pomace, 0.5 g/L cheese whey at the end of the 48 h incubation. The maximum total C16 and C18 FAME rates were detected at the 25 °C, in the presence of 4 g/L dried C. hoffmannii biomass, methanol and 3% NaOH by using the in-situ transesterification process at the end of the 0.5 h as 96.3%. This is the first report about the usage of C. hoffmannii lipids obtained from carrot pomace for sustainable biodiesel production.

Evaluation of wearable sensors for physiologic monitoring of individually experienced temperatures in outdoor workers in southeastern U.S

Climate-related increases in global mean temperature and the intensification of heat waves present a significant threat to outdoor workers. Limited research has been completed to assess the potential differences in heat exposures that exist between individuals within similar microenvironments. Yet, there is a paucity of individual data characterizing patterns of individually experienced temperatures in workers and the associated physiologic heat strain response. The objective of this study was to apply a wearable sensor-based approach to examine the occupational, environmental, and behavioral factors that contribute to individual-level variations in heat strain in grounds maintenance workers. Outdoor workers from three diverse climatic locations in the southeastern United States - high temperature, high temperature + high humidity, and moderate temperature environments - participated in personal heat exposure monitoring during a 5-day work period in the summer. We performed Cox proportional hazards modeling to estimate associations between multiple heat strain events per worker and changes in individually experienced temperatures. Heat strain risk was higher among workers with a place to cool-off, higher education, and who worked in hotter temperatures. A mismatch was observed between workers' perceptions of heat strain and actual heat strain prevalence across exposure groups. We also used a quasi-Poisson regression with distributed lag non-linear function to estimate the non-linear and lag effects of individually experienced temperatures on risk of heat strain. The association between increasing temperature and heat strain was nonlinear and exhibited an U-shaped relationship. Heat strain was less common during issued heat warnings demonstrating behavioral adaptive actions taken by workers. This study is one of the first temperature monitoring studies to quantify the individual-level exposure-response function in this vulnerable population and highlights the elevated risk of heat strain both immediately and several days after worker exposure to high temperatures.

The MJA-Lancet Countdown on health and climate change: Australian policy inaction threatens lives

Climate plays an important role in human health and it is well established that climate change can have very significant impacts in this regard. In partnership with The Lancet and the MJA, we present the inaugural Australian Countdown assessment of progress on climate change and health. This comprehensive assessment examines 41 indicators across five broad sections: climate change impacts, exposures and vulnerability; adaptation, planning and resilience for health; mitigation actions and health co-benefits; economics and finance; and public and political engagement. These indicators and the methods used for each are largely consistent with those of the Lancet Countdown global assessment published in October 2017, but with an Australian focus. Significant developments include the addition of a new indicator on mental health. Overall, we find that Australia is vulnerable to the impacts of climate change on health, and that policy inaction in this regard threatens Australian lives. In a number of respects, Australia has gone backwards and now lags behind other high income countries such as Germany and the United Kingdom. Examples include the persistence of a very high carbon-intensive energy system in Australia, and its slow transition to renewables and low carbon electricity generation. However, we also find some examples of good progress, such as heatwave response planning. Given the overall poor state of progress on climate change and health in Australia, this country now has an enormous opportunity to take action and protect human health and lives. Australia has the technical knowhow and intellect to do this, and our annual updates of this assessment will track Australia's engagement with and progress on this vitally important issue.

Mapping the Solastalgia Literature: A Scoping Review Study

Solastalgia is a relatively new concept for understanding the links between human and ecosystem health, specifically, the cumulative impacts of climatic and environmental change on mental, emotional, and spiritual health. Given the speed and scale of climate change alongside biodiversity loss, pollution, deforestation, unbridled resource extraction, and other environmental challenges, more and more people will experience solastalgia. This study reviewed 15 years of scholarly literature on solastalgia using a scoping review process. Our goal was to advance conceptual clarity, synthesize the literature, and identify priorities for future research. Four specific questions guided the review process: (1) How is solastalgia conceptualized and applied in the literature?; (2) How is solastalgia experienced and measured in the literature?; (3) How is ‘place’ understood in the solastalgia literature?; and (4) Does the current body of literature on solastalgia engage with Indigenous worldviews and experiences? Overall, we find there is a need for additional research employing diverse methodologies, across a greater diversity of people and places, and conducted in collaboration with affected populations and potential knowledge, alongside greater attention to the practical implications and applications of solastalgia research. We also call for continued efforts to advance conceptual clarity and theoretical foundations. Key outcomes of this study include our use of the landscape construct in relation to solastalgia and a call to better understand Indigenous peoples’ lived experiences of landscape transformation and degradation in the context of historical traumas.
