Should climate and health researchers accept funding from industries that profit from climate-damaging consumption? In this Personal View, we aim to ignite discussions on this key topic and to introduce a guideline to possibly help climate and health researchers grappling with this complex question. Drawing from existing tools focused on other public health issues and the conclusions of the 2023 Lancet Series on commercial determinants of health, we propose a guideline comprising six parts: meeting public health and climate goals; building credibility and trust; avoiding undue dependence on particular sources of funding; not inflating without good reason the public image of industry; embedding processes to ensure transparency and independence; and protecting the freedom to publish. We invite other climate and public health scientists to report their own experiences and provide feedback on this guideline., Competing Interests: Declaration of interests AB has received grants from German Research Foundation (DFG), Wellcome Trust, European Commission, Tidall Foundation, and Habitat for Humanity on climate change and health; and received a climate and health award from Bellagio Rockefeller Foundation.

The MJA-Lancet Countdown on health and climate change in Australia was established in 2017 and produced its first national assessment in 2018 and annual updates in 2019, 2020, 2021 and 2022. It examines five broad domains: health hazards, exposures and impacts; adaptation, planning and resilience for health; mitigation actions and health co-benefits; economics and finance; and public and political engagement. In this, the sixth report of the MJA-Lancet Countdown, we track progress on an extensive suite of indicators across these five domains, accessing and presenting the latest data and further refining and developing our analyses. Our results highlight the health and economic costs of inaction on health and climate change. A series of major flood events across the four eastern states of Australia in 2022 was the main contributor to insured losses from climate-related catastrophes of $7.168 billion - the highest amount on record. The floods also directly caused 23 deaths and resulted in the displacement of tens of thousands of people. High red meat and processed meat consumption and insufficient consumption of fruit and vegetables accounted for about half of the 87 166 diet-related deaths in Australia in 2021. Correction of this imbalance would both save lives and reduce the heavy carbon footprint associated with meat production. We find signs of progress on health and climate change. Importantly, the Australian Government released Australia's first National Health and Climate Strategy, and the Government of Western Australia is preparing a Health Sector Adaptation Plan. We also find increasing action on, and engagement with, health and climate change at a community level, with the number of electric vehicle sales almost doubling in 2022 compared with 2021, and with a 65% increase in coverage of health and climate change in the media in 2022 compared with 2021. Overall, the urgency of substantial enhancements in Australia's mitigation and adaptation responses to the enormous health and climate change challenge cannot be overstated. Australia's energy system, and its health care sector, currently emit an unreasonable and unjust proportion of greenhouse gases into the atmosphere. As the Lancet Countdown enters its second and most critical phase in the leadup to 2030, the depth and breadth of our assessment of health and climate change will be augmented to increasingly examine Australia in its regional context, and to better measure and track key issues in Australia such as mental health and Aboriginal and Torres Strait Islander health and wellbeing., (© 2024 The Authors.

Climate change exacts a devastating toll on health that is rarely incorporated into the economic calculus of climate action. By aligning health and environmental policy and collaborating across borders, governments and industries can develop powerful initiatives to promote both environmental and human health.

The MJA-Lancet Countdown on health and climate change in Australia was established in 2017 and produced its first national assessment in 2018 and annual updates in 2019, 2020 and 2021. It examines 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. In this, the fifth year of the MJA-Lancet Countdown, we track progress on an extensive suite of indicators across these five domains, accessing and presenting the latest data and further refining and developing our analyses. Within just two years, Australia has experienced two unprecedented national catastrophes - the 2019-2020 summer heatwaves and bushfires and the 2021-2022 torrential rains and flooding. Such events are costing lives and displacing tens of thousands of people. Further, our analysis shows that there are clear signs that Australia's health emergency management capacity substantially decreased in 2021. We find some signs of progress with respect to health and climate change. The states continue to lead the way in health and climate change adaptation planning, with the Victorian plan being published in early 2022. At the national level, we note progress in health and climate change research funding by the National Health and Medical Research Council. We now also see an acceleration in the uptake of electric vehicles and continued uptake of and employment in renewable energy. However, we also find Australia's transition to renewables and zero carbon remains unacceptably slow, and the Australian Government's continuing failure to produce a national climate change and health adaptation plan places the health and lives of Australians at unnecessary risk today, which does not bode well for the future., (© 2022 The Authors.

Objective: To determine if global warming has changed the balance of summer and winter deaths in Australia., Methods: Counts of summer and winter cause-specific deaths of subjects aged 55 and over for the years 1968-2018 were entered into a Poisson time-series regression. Analysis was stratified by states and territories of Australia, by sex, age and cause of death (respiratory, cardiovascular, and renal diseases). The warmest and coldest subsets of seasons were compared., Results: Warming over 51 years was associated with a long-term increase in the ratio of summer to winter mortality from 0.73 in the summer of 1969 to 0.83 in the summer of 2018. The increase occurred faster in years that were warmer than average., Conclusions: Mortality in the warmest and coldest times of the year is converging as annual average temperatures rise. Implications for public health: If climate change continues, deaths in the hottest months will come to dominate the burden of mortality in Australia., (© 2021 The Authors.)

We know very well what causes climate change, and in general terms, what the dangers are. This is a new kind of environmental problem, it is not like taking lead out of petrol, and it is important to understand why responding to climate change is so challenging. But that is no reason to give up: in fact there are many opportunities to intervene, including actions that can be taken by surgeons and other health professionals., (© 2019 Royal Australasian College of Surgeons.)

Rapid and wide-ranging reductions in greenhouse gas emissions are required to meet the climate targets agreed upon at the 2015 Paris climate conference. There will be significant transition risks for health, livelihoods, and ecosystems associated with large-scale mitigation, but also opportunities. The aim of this study was to investigate the impacts, positive and negative, of climate policies on population health in China. We review the Intended Nationally Determined Contribution (INDC) that China took to the Paris meeting, link commitments in the INDC to national planning documents relevant to environment and health, and search the literature for Chinese publications on health trade-offs and synergies. Synergies are evident in the measures taken to reduce local air pollution in China: controls on coal burning have materially improved local air quality and benefited health. But there may be risks to health also, depending on how policies are implemented and what safeguards are provided. To date most assessments of the health impacts of climate policies in China have been modelling studies. We recommend work of this kind is complemented by observational research to identify unexpected impacts and vulnerabilities. It will become even more important to undertake this work as emission reductions accelerate to meet the Paris climate targets., (Copyright © 2019 Elsevier Inc. All rights reserved.)

To date, greenhouse gas (GHG) emissions, mitigation strategies and the accompanying health co-benefits in different economic sectors have not been fully investigated. The purpose of this paper is to review comprehensively the evidence on GHG mitigation measures and the related health co-benefits, identify knowledge gaps, and provide recommendations to promote further development and implementation of climate change response policies. Evidence on GHG emissions, abatement measures and related health co-benefits has been observed at regional, national and global levels, involving both low- and high-income societies. GHG mitigation actions have mainly been taken in five sectors: energy generation, transport, food and agriculture, household and industry, consistent with the main sources of GHG emissions. GHGs and air pollutants to a large extent stem from the same sources and are inseparable in terms of their atmospheric evolution and effects on ecosystem; thus, GHG reductions are usually, although not always, estimated to have cost effective co-benefits for public health. Some integrated mitigation strategies involving multiple sectors, which tend to create greater health benefits. The pros and cons of different mitigation measures, issues with existing knowledge, priorities for research, and potential policy implications were also discussed. Findings from this study can play a role not only in motivating large GHG emitters to make decisive changes in GHG emissions, but also in facilitating cooperation at international, national and regional levels, to promote GHG mitigation policies that protect public health from climate change and air pollution simultaneously., (Copyright © 2018 Elsevier Ltd.

Background and Objectives: Public health co-benefits from curbing climate change can make greenhouse gas (GHG) mitigation strategies more attractive and increase their implementation. The purpose of this systematic review is to summarize the evidence of these health co-benefits to improve our understanding of the mitigation measures involved, potential mechanisms, and relevant uncertainties., Methods: A comprehensive search for peer-reviewed studies published in English was conducted using the primary electronic databases. Reference lists from these articles were reviewed and manual searches were performed to supplement relevant studies. The identified records were screened based on inclusion criteria. We extracted data from the final retrieved papers using a pre-designed data extraction form and a quality assessment was conducted. The studies were heterogeneities, so meta-analysis was not possible and instead evidence was synthesized using narrative summaries., Results: Thirty-six studies were identified. We identified GHG mitigation strategies in five domains - energy generation, transportation, food and agriculture, households, and industry and economy - which usually, although not always, bring co-benefits for public health. These health gains are likely to be multiplied by comprehensive measures that include more than one sectors., Conclusions: GHG mitigation strategies can bring about substantial and possibly cost-effective public health co-benefits. These findings are highly relevant to policy makers and other stakeholders since they point to the compounding value of taking concerted action against climate change and air pollution., (Copyright © 2018.

Background: Detection and attribution of health impacts caused by climate change uses formal methods to determine a ) whether the occurrence of adverse health outcomes has changed, and b ) the extent to which that change could be attributed to climate change. There have been limited efforts to undertake detection and attribution analyses in health., Objective: Our goal was to show a range of approaches for conducting detection and attribution analyses., Results: Case studies for heatwaves, Lyme disease in Canada, and Vibrio emergence in northern Europe highlight evidence that climate change is adversely affecting human health. Changes in rates and geographic distribution of adverse health outcomes were detected, and, in each instance, a proportion of the observed changes could, in our judgment, be attributed to changes in weather patterns associated with climate change., Conclusions: The results of detection and attribution studies can inform evidence-based risk management to reduce current, and plan for future, changes in health risks associated with climate change. Gaining a better understanding of the size, timing, and distribution of the climate change burden of disease and injury requires reliable long-term data sets, more knowledge about the factors that confound and modify the effects of climate on health, and refinement of analytic techniques for detection and attribution. At the same time, significant advances are possible in the absence of complete data and statistical certainty: there is a place for well-informed judgments, based on understanding of underlying processes and matching of patterns of health, climate, and other determinants of human well-being. https://doi.org/10.1289/EHP1509.

Background: Between 2010 and 2012, the World Health Organization Division of Pacific Technical Support led a regional climate change and health vulnerability assessment and adaptation planning project, in collaboration with health sector partners, in 13 Pacific island countries-Cook Islands, Federated States of Micronesia, Fiji, Kiribati, Marshall Islands, Nauru, Niue, Palau, Samoa, Solomon Islands, Tonga, Tuvalu, and Vanuatu., Objective: We assessed the vulnerabilities of Pacific island countries to the health impacts of climate change and planned adaptation strategies to minimize such threats to health., Methods: This assessment involved a combination of quantitative and qualitative techniques. The former included descriptive epidemiology, time series analyses, Poisson regression, and spatial modeling of climate and climate-sensitive disease data, in the few instances where this was possible; the latter included wide stakeholder consultations, iterative consensus building, and expert opinion. Vulnerabilities were ranked using a "likelihood versus impact" matrix, and adaptation strategies were prioritized and planned accordingly., Results: The highest-priority climate-sensitive health risks in Pacific island countries included trauma from extreme weather events, heat-related illnesses, compromised safety and security of water and food, vector-borne diseases, zoonoses, respiratory illnesses, psychosocial ill-health, non-communicable diseases, population pressures, and health system deficiencies. Adaptation strategies relating to these climate change and health risks could be clustered according to categories common to many countries in the Pacific region., Conclusion: Pacific island countries are among the most vulnerable in the world to the health impacts of climate change. This vulnerability is a function of their unique geographic, demographic, and socioeconomic characteristics combined with their exposure to changing weather patterns associated with climate change, the health risks entailed, and the limited capacity of the countries to manage and adapt in the face of such risks.

Human-caused climate change poses an increasingly serious and urgent threat to health and health equity. Under all the climate projections reported in the recent Intergovernmental Panel on Climate Change assessment, New Zealand will experience direct impacts, biologically mediated impacts, and socially mediated impacts on health. These will disproportionately affect populations that already experience disadvantage and poorer health. Without rapid global action to reduce greenhouse gas emissions (particularly from fossil fuels), the world will breach its carbon budget and may experience high levels of warming (land temperatures on average 4-7 degrees Celsius higher by 2100). This level of climate change would threaten the habitability of some parts of the world because of extreme weather, limits on working outdoors, and severely reduced food production. However, well-planned action to reduce greenhouse gas emissions could bring about substantial benefits to health, and help New Zealand tackle its costly burden of health inequity and chronic disease.

Kiribati-a low-lying, resource-poor Pacific atoll nation-is one of the most vulnerable countries in the World to the impacts of climate change, including the likely detrimental effects on human health. We describe the preparation of a climate change and health adaptation plan for Kiribati carried out by the World Health Organization and the Kiribati Ministry of Health and Medical Services, including an assessment of risks to health, sources of vulnerability and suggestions for highest priority adaptation responses. This paper identifies advantages and disadvantages in the process that was followed, lays out a future direction of climate change and health adaptation work in Kiribati, and proposes lessons that may be applicable to other small, developing island nations as they prepare for and adapt to the impacts of climate change on health.

Background: Tibet, average altitude more than 4,000 meters, is warming faster than anywhere else in China. The increase in temperatures may aggravate existing health problems and lead to the emergence of new risks. However, there are no actions being taken at present to protect population health due to limited understanding about the range and magnitude of health effects of climate change., Methods: The study was a cross-sectional survey of 619 respondents from urban Lhasa, Tibet in August 2012 with the aim to investigate public perceptions of risk, heat experiences, and coping resources., Results: Respondents are aware of the warming that has occurred in Lhasa in recent years. Over 78% reported that rising temperature is either a "very" or "somewhat" serious threat to their own health, and nearly 40% reported they had experienced heat-related symptoms. Sex, age, education and income influenced perceived risks, health status, and heat experience. The vast majority of respondents reported that they had altered their behaviour on hot summer days. Bakuo, a sub-district at the city center, is considered especially vulnerable to heat because of sparse vegetation, high population density, poor dwelling conditions and a high proportion of low-income population. However, neighborhood social ties were stronger in Bakuo than other study locations., Conclusions: The study suggests that actions are needed now to minimize downside effects of rapid warming in Tibet, because of increasing human exposure to high temperatures and uneven distribution of the resources needed to cope.

Human-induced climate change is now the central health issue facing humanity. The World Medical Association recently adopted the Declaration of Delhi, committing the medical profession to mitigate and adapt to the effects of climate change. This is new professional territory for many doctors. Even so, the profession has often engaged with issues outside 'the health sector' when the stakes are high, for example leaded petrol, road safety, tobacco, and nuclear weapons. The scientific basis to the declaration merits scrutiny in light of commonly used contrary arguments. Decisions in medicine, as elsewhere, must be taken on the evidence to hand, weighing up the risks, given that complete knowledge is seldom available and time is precious. There are strong analogies between clinical experience and our approach to planetary climate. The relevant context for scientific observations on climate is the world's multi-gigatonne annual CO2-equivalent greenhouse gas emissions. Emissions drive changes in concentrations of greenhouse gases, which matters when they are rapid or prolonged. The current variation in global temperature is alarming, even when within 'normal range'. Climate models inform and guide present-day decision-making, and perform well in explaining observed warming. They corroborate other evidence that tells us that CO2 and other greenhouse gases are harmful at current atmospheric concentrations. As a profession and as global citizens, we need to move beyond dissent and denial about anthropogenic climate change. The WMA correctly says that circumstances now require us all to take action.

BackgroundModeling suggests that climate change mitigation actions can have substantial human health benefits that accrue quickly and locally. Documenting the benefits can help drive more ambitious and health-protective climate change mitigation actions; however, documenting the adverse health effects can help to avoid them. Estimating the health effects of mitigation (HEM) actions can help policy makers prioritize investments based not only on mitigation potential but also on expected health benefits. To date, however, the wide range of incompatible approaches taken to developing and reporting HEM estimates has limited their comparability and usefulness to policymakers.ObjectiveThe objective of this effort was to generate guidance for modeling studies on scoping, estimating, and reporting population health effects from climate change mitigation actions.MethodsAn expert panel of HEM researchers was recruited to participate in developing guidance for conducting HEM studies. The primary literature and a synthesis of HEM studies were provided to the panel. Panel members then participated in a modified Delphi exercise to identify areas of consensus regarding HEM estimation. Finally, the panel met to review and discuss consensus findings, resolve remaining differences, and generate guidance regarding conducting HEM studies.ResultsThe panel generated a checklist of recommendations regarding stakeholder engagement: HEM modeling, including model structure, scope and scale, demographics, time horizons, counterfactuals, health response functions, and metrics; parameterization and reporting; approaches to uncertainty and sensitivity analysis; accounting for policy uptake; and discounting.DiscussionThis checklist provides guidance for conducting and reporting HEM estimates to make them more comparable and useful for policymakers. Harmonization of HEM estimates has the potential to lead to advances in and improved synthesis of policy-relevant research that can inform evidence-based decision making and practice. https://doi.org/10.1289/EHP6745.

Observed climate changes in Pacific island countries (PICs) are causing detrimental effects on the health of communities. Increased frequency and intensity of cyclones, more extremely hot days, and changes in rainfall patterns can change the geographic distribution of vector-borne diseases, decrease food and water security and safety, and strain health service capacity. These impacts are projected to worsen with additional climate change in the absence of strong and effective mitigation and adaptation measures. Health vulnerability and adaptation assessments conducted in twelve PICs in 2014 highlighted significant knowledge gaps on the national health risks of climate change and on adaptation implementation and policy translation. We synthesize recent research to identify approaches to support evidence-based policymaking to increase resilience of health systems in the Pacific. Broad areas where further and substantial investment and support are needed include: (i) health workforce capacity development; (ii) enhanced surveillance and monitoring systems, and (iii) research to enhance understanding of risks and effective interventions and their subsequent translation into practice and policy. Finally, health facilities need urgent upgrades; many are old and located in coastal areas, and are heavy users of coal-fired electricity. [ABSTRACT FROM AUTHOR]

Impacts of climate change in the Pacific are far reaching and include effects on mental health and wellbeing. Pacific concepts around the interrelation of these global giants are yet to be described. The aim of this study was to seek consensus amongst Pacific mental health and/or climate change experts on key principles underpinning mental health and wellbeing, and climate change, and the intersection of the two, for Pacific peoples. The Delphi method included forming a panel of 70 experts. Two rounds of online questionnaires sought their views on mental health and wellbeing, and climate change and the impact upon Pacific peoples. Of the panel 86% identified with one or more Pacific ethnicities. Six themes emerged, 92% of items reached consensus and 36% reached strong consensus of >95%. Recurring subthemes included culture and spirituality, family and community, connection to ancestors, connection to the environment, resilience, disasters, livelihoods, government, education, workforce, migration and stigma. This is the first time these concepts have been explored and described for, and by Pacific peoples in this format. It is a necessary first step towards development of responses in preparedness of mental health services, in the Pacific region, and Aotearoa New Zealand. [ABSTRACT FROM AUTHOR]

Both housing structure and occupant use of homes influence health outcomes and carbon emissions. However, it remains unclear how these elements interact. We conducted semi-structured interviews with 13 technical experts in the New Zealand housing and health sectors. We applied the general inductive method for qualitative data analysis and generated frameworks for 'housing structure' and 'occupant behaviour' including: (i) issues or barriers, (ii) solutions or facilitators and (iii) potential interventions. Addressing the location, aspect and design of the house were seen to offer the greatest gains in energy efficiency, indoor temperature and air quality. Insulation, heating and ventilation were the most critical technologies for promoting health. Raising consumer expectations of housing standards was thought to be critical to boost demand and drive supply for better quality housing. Participants proposed that sharing personal stories, combining information with active strategies (demonstration, skill rehearsal) and providing incentives were promising strategies to realise the full potential of health-enhancing home design. Schools and the local community were identified as suitable settings. We conclude that public health interventions should not only aim to build homes that maximise health and environmental outcomes but must also pay attention to how occupants behave and interface with their houses.

The article discusses a study by J. P. Healy and colleagues published in the issue which investigated the effects of absolute temperature and temperature variability within the warm cold halves of the year in the U.S. Topics include finding on mortality rates when daily average temperatures varied more, ways to adapt to a variable climate, and suggestions to minimize the negative impacts of climate change.

Background: Climate change may significantly affect human health. The possible effects of high ambient temperature must be better understood, particularly in terms of certain diseases’ sensitivity to heat (as reflected in relative risks [RR]) and the consequent disease burden (number or fraction of cases attributable to high temperatures), in order to manage the threat. Purpose: This study investigated the number of deaths attributable to abnormally high ambient temperatures in Seoul, South Korea, for a wide range of diseases. Method: The relationship between mortality and daily maximum temperature using a generalized linear model was analyzed. The threshold temperature was defined as the 90th percentile of maximum daily temperatures. Deaths were classified according to ICD-10 codes, and for each disease, the RR and attributable fractions were determined. Using these fractions, the total number of deaths attributable to daily maximum temperatures above the threshold value, from 1992 to 2009, was calculated. Data analyses were conducted in 2012–2013. Results: Heat-attributable deaths accounted for 3,177 of the 271,633 deaths from all causes. Neurological (RR 1.07; 95% CI, 1.04–1.11) and mental and behavioral disorders (RR 1.04; 95% CI, 1.01–1.07) had relatively high increases in the RR of mortality. The most heat-sensitive diseases (those with the highest RRs) were not the diseases that caused the largest number of deaths attributable to high temperatures. Conclusion: This study estimated RRs and deaths attributable to high ambient temperature for a wide variety of diseases. Prevention-related policies must account for both particular vulnerabilities (heat-sensitive diseases with high RRs) and the major causes of the heat mortality burden (common conditions less sensitive to high temperatures).

Background: The growing health risks associated with greenhouse gas emissions highlight the need for new energy policies that emphasize efficiency and low-carbon energy intensity. oBjectives: We assessed the relationships among electricity use, coal consumption, and health outcomes. Methods: Using time-series data sets from 41 countries with varying development trajectories between 1965 and 2005, we developed an autoregressive model of life expectancy (LE) and infant mortality (IM) based on electricity consumption, coal consumption, and previous year's LE or IM. Prediction of health impacts from the Greenhouse Gas and Air Pollution Interactions and Synergies (GAINS) integrated air pollution emissions health impact model for coal-fired power plants was compared with the time-series model results. results: The time-series model predicted that increased electricity consumption was associated with reduced IM for countries that started with relatively high IM (> 100/1,000 live births) and low LE (< 57 years) in 1965, whereas LE was not significantly associated with electricity consumption regard­less of IM and LE in 1965. Increasing coal consumption was associated with increased IM and reduced LE after accounting for electricity consumption. These results are consistent with results based on the GAINS model and previously published estimates of disease burdens attributable to energy-related environmental factors, including indoor and outdoor air pollution and water and sanitation. conclusions: Increased electricity consumption in countries with IM < 100/1,000 live births does not lead to greater health benefits, whereas coal consumption has significant detrimental health impacts.

The coastal zone of the Pacific Rim is home for about one-third of the world's population. Disproportionate growth of Far Eastern economies has produced a disproportionate share of related environmental difficulties. As the region searches for acceptable compromises between growth and environmental quality, its influence on global environmental health is certain to increase. Consequences of global environmental change such as habitat alteration, storms, and sea-level rise will be particularly acute among Pacific Rim nations. Adverse health effects from arsenic exposure in Pacific Rim nations have been used to justify drinking water standards in the United States and elsewhere. As global manufacturing in the Pacific Rim increases, the centroid of global air quality and waste management issues will shift further toward Far Eastern nations. The Eleventh International Conference of the Pacific Basin Consortium (PBC) was held in September 2005 in Honolulu, Hawaii. The purpose of the conference was to bring together individuals to discuss regional challenges to sustainable growth. The historic emphasis of the conference on hazardous wastes in relation to human health makes the PBC an ideal forum for discussing technical aspects of sustainable economic growth in the Pacific region. That role is reflected in the 2005 PBC conference themes, which included management of arsenic in potable waters, air quality, climate change, pesticides, mercury, and electronics industry waste—each with emphasis on relationships to human health. Arsenic management exemplifies the manner in which the PBC can focus interdisciplinary discussion in a single technical area. The conference program provided talks on arsenic toxicology, treatment technologies, management of arsenic-bearing residuals from water treatment, and the probable societal costs and benefits of arsenic management.

The article discusses how responding to climate change might affect health of greater urban density. Topics include separating housing from arterial roads, making noise reduction a priority in planning and design, limiting the height of high-rise housing, providing high quality local amenities, and avoiding neighborhood injury hazards (e.g. curb parking, poor lighting, unkept and obstructed public places, high traffic speeds and volumes).

The transport system influences health, including the onset of new cancers, in both positive and negative ways. Transport affects the frequency of cancer via access to healthcare, employment and other goods and services of society; physical (in)activity; exposure to transport-related pollution and climate change. In addition, avoidable transport health impacts overload the health system that delivers cancer care. The current transport system in Aotearoa/New Zealand is the result of policy choices made in the last 50–70 years which have privileged the private motor vehicle. We discuss examples of local work to support a healthier transport system, including action research with government partners creating infrastructure to support healthy travel, health professional advocacy in transport policy processes and involvement in coronial processes and a subsequent government advisory group. These, and other attempts at change, have had limited impact because of the elements that hold the current system in place; the weak regulatory architecture and institutions, commercial influences on policy and funding arrangements. Creating a healthy, cancer-preventing transport system requires not just focus on specific policy changes but reform of the policy making apparatus to ensure healthy people and planet are at the centre of decision making.

An editorial is presented which addresses the authors' views about climate change denial under the leadership of U.S. President Donald Trump, and it mentions greenhouse gas and climate change mitigation efforts by governments in American states and municipalities. The relationship between public health and climate change is assessed, along with greenhouse gas emissions in China, Trump's decision to withdraw from the Paris Climate Agreement, and India's renewable energy sources.

The article presents part of a response from authors of an Intergovernmental Panel on Climate Change (IPCC) report to comments made in a policy forum by J. Bongaarts and B.C. O'Neill regarding the IPCC's decision to overlook the role of population growth on climate change.

Summary: Background: Existing theoretical models of the potential effects of climate change on vector-borne diseases do not account for social factors such as population increase, or interactions between climate variables. Our aim was to investigate the potential effects of global climate change on human health, and in particular, on the transmission of vector-borne diseases. Methods: We modelled the reported global distribution of dengue fever on the basis of vapour pressure, which is a measure of humidity. We assessed changes in the geographical limits of dengue fever transmission, and in the number of people at risk of dengue by incorporating future climate change and human population projections into our model. Findings: We showed that the current geographical limits of dengue fever transmission can be modelled with 89% accuracy on the basis of long-term average vapour pressure. In 1990, almost 30% of the world population, 1.5 billion people, lived in regions where the estimated risk of dengue transmission was greater than 50%. With population and climate change projections for 2085, we estimate that about 5-6 billion people (50-60% of the projected global population) would be at risk of dengue transmission, compared with 3.5 billion people, or 35% of the population, if climate change did not happen. Interpretation: We conclude that climate change is likely to increase the area of land with a climate suitable for dengue fever transmission, and that if no other contributing factors were to change, a large proportion of the human population would then be put at risk.
