The new review paper, The Impacts of Climate Change on Health, identifies the extent to which increasing emissions, extreme weather and temperatures elevate health risks, from infectious disease to malnutrition, and assesses the associated health burden. It concludes that the health burden will exce...ed the level of demand that health systems are prepared for.

Climate change is a verified, global phenomenon, but its consequences will not be evenly distributed. Developing countries and small island nations will be the most affected. Countries will experience more frequent extreme weather events and resulting changes in water quality and availability, incre...ased contamination of air, and food security problems. Health impact due to climate change include diarrhoeal diseases, vector-borne diseases, heat stress, malnutrition, deaths and injuries due to extreme weather events and mental stress.

Current evidence that the climate is changing is overwhelming. Impacts of climate change and variability are being observed: more intense heat-waves, fires and floods; and increased prevalence of food- water- and vector-borne diseases. Climate change will put pressure on environmental and health det...erminants, such as food safety, air pollution and water quantity and quality. A climate-resilient future depends fundamentally on reducing greenhouse gas emissions. Limiting warming to below 2 °C requires transformational technological, institutional, political and behavioural changes: the foundations for this are laid out in the Paris Agreement of December 2015. The health sector can lead by example, shifting to environmentally friendly practices and minimizing its carbon emissions. A climate-resilient future will increasingly depend on managing and reducing climate change risks to protect health. In the near term, this can be enhanced by including climate change in national health programming and creating climate-resilient health systems.

Climate change presents significant challenges to human health and biodiversity. Increased numbers of extreme climate events, such as heat waves, droughts or flooding, threaten human health and well-being, both directly and indirectly, through impaired ecosystem functioning and reduced ecosystem ser...vices. In addition, the prevalence of non-communicable diseases is rising, causing ill health and accelerating costs to the health sector. Nature-based solutions, such as the provision and management of biodiversity, can facilitate human health and well-being, and mitigate the negative effects of climate change.

his sequel to the Groundswell report includes projections and analysis of internal climate migration for three new regions: East Asia and the Pacific, North Africa, and Eastern Europe and Central Asia. Qualitative analyses of climate-related mobility in countries of the Mashreq and in Small Island D...eveloping States (SIDS) are also provided. This new report builds on the scenario-based modeling approach of the previous Groundswell report from 2018, which covered Sub-Saharan Africa, South Asia, and Latin America. The two reports’ combined findings provide, for the first time, a global picture of the potential scale of internal climate migration across the six regions, allowing for a better understanding of how slow-onset climate change impacts, population dynamics, and development contexts shape mobility trends.

This chapter reviews the emerging importance of pollen allergies in relation to ongoing climate change. Allergic diseases have been increasing in prevalence over the last decades, partly as the result of the impact of climate change. ...Increased sensitisation rates and more severe symptoms have been the partial outcome of: increased pollen production of wind-pollinated plants resulting in long-term increased abundance of pollen in the air we breathe; earlier shifts of airborne pollen seasons making occurrence of allergic symptoms harder to predict and deal with efficiently; increased allergenicity of pollen causing more severe health effects in allergic individuals; introduction of new, invasive allergenic plant species causing new sensitisations; environment-environment interactions, such as plants and hosted microorganisms, i.e. fungi and bacteria, which comprise a complex and dynamic system, with additive, presently unforeseeable influences on human health; environment-human interactions, as the consequence of a combination of environmental factors, like air pollution, global warming, urbanisation and microclimatic variability, which create a multi-resolution spatiotemporal system that requires new processing technologies and huge data inflow in order to be thoroughly investigated. We suggest that novel, real-time, personalised pollen information services, like mobile-app risk alerts, must be developed to provide the optimum first line of allergy management.

Extreme heat events (EHEs) are a leading cause of weather-related injury and death in the United States, and under a changing climate, these meteorological episodes are predicted to increase in both frequency and intensity. Prolonged heat exposure from EHEs places an increased strain on the heart an...d may lead to heat-related illness if the cardiovascular system fails to properly thermoregulate internal body temperature. Every individual is susceptible to heat-related illness, however, those with reduced cardiovascular function and pre-existing cardiovascular diseases are at a greater risk for morbidity and mortality during EHEs. This document gives an overview of our current understanding of heat exposure and its impact on cardiovascular health outcomes, an overview of the medications that may exacerbate heat-related cardiovascular illness, and asummary of the interaction between extreme heat and air pollutants, and their collective impact on cardiovascular health. Additionally, this document summarizes epidemiologic evidence and identifies gaps in the extant peer-reviewed literature on the effectiveness of strategies and interventions to protect against heat-related cardiovascular disease and death. This information is intended to aid health departments and other health professionals in understanding and responding to the impacts of heat exposure on cardiovascular health.

The war in Ukraine has rapidly taken the form of a series of conflicts in urban contexts. Urban warfare has a long history, but unfortunately, we can see from this conflict just how topical it remains. Generally, a first phase involves imposing a siege and forcing the city to surrender by making liv...ing conditions impossible.

Water is the lifeblood of planetary health and human civilisation. As a critical source of fresh water, rivers underpin civilisations, past and present. However, rivers constantly change in response to environmental and human pressures. Protecting global river systems from climate change and other a...nthropogenic activities (e.g., mining, pollution, dam construction), and understanding the interactions with human health (e.g., through the spread of water-borne and infectious diseases) has become a critical concern.

The threat climate change poses to health, equity, and development has been rigorously documented. However, in an era marked by economic crisis, regional conflicts, natural disasters and growing disparities between rich and poor, the joint global actions required to address climate change have been ...vigorously debated – and critical decisions postponed.
This document, part of WHO’s Health in the Green Economy series, describes how many climate change measures can be “win-wins” for people and the planet.
These policies yield large, immediate public health benefits while reducing the upward trajectory of greenhouse gas emissions. Many of these policies can improve the health and equity of people in poor countries and assist developing countries in adapting to climate change that is already occurring, as evidenced by more extreme storms, flooding, drought and heatwaves.
WHO’s Department of Public Health and Environment launched the Health in the Green Economy initiative in 2010 to review potential health and equity “co-benefits” of proposed climate change measures – as well as relevant risks.
This review examines mitigation strategies discussed in the Fourth Assessment Report of the Intergovernmental Panel on Climate Change which constitutes the most broad-based global review of mitigation options by scientific experts.
