Report of the Expert Consultation on Extreme Heat Risk Reduction: Towards a common global framework
2025
This report summarizes the proceedings of the 17–19 December 2024 Expert Consultation ‘Extreme Heat Risk Reduction Towards a common global framework‘, where over 60 experts from government, international organizations, philanthropy, academia, and civil society met at WMO Headquarters in Geneva. Co-hosted by the WHO-WMO Joint Office for Climate and Health, UNDRR, and GHHIN, the consultation aimed to develop a shared framework for extreme heat risk governance. Through panels, case studies, and working sessions, participants examined governance challenges, cross-sectoral coordination, and strategies to scale effective solutions. A key focus was shifting from short-term projects to sustainable, institutionalized governance. The consultation produced three main outcomes: Consensus on the need for a common governance framework; Definition of core components including data integration, capacity building, and policy alignment; Agreement on a roadmap leading to a framework launch at GP2025. Follow-up focus groups in spring 2025 will address remaining gaps, especially in sectors such as transport, energy, cooling, and environmental management.
Heat and Health: Action Statement from the Global Heat Health Information Network
2023
The Global Heat Health Information Network invites civil society, national governments and the international community to recognize the pressing urgency of addressing the health impacts of extreme heat and take bold, comprehensive, and coordinated actions to protect the well-being of our planet and its people.
2023 State of Climate Services: Health
2023
The interconnection between climate and health is undeniable. The climate, exacerbated by climate change, poses systematic and serious threats to human health. Climate change is documented to be impacting human health in many complex ways, including by leading to death, injury and illness from heat stress, the disruption of ecosystems and food systems, increases in food-, and water- and vector-borne diseases, and exposure to air pollution. The 2023 edition of the WMO State of Climate Services report focuses on health, which highlights the importance of climate services and information in protecting lives and livelihoods. While there are many good examples of how countries are successfully using climate information and services to detect, monitor, predict and manage climate-related health risks, there is huge potential for enhancing the impact of climate science and services for health. This report examines the current state of climate services for health, and presents a series of next steps, recommendations and case studies.
Summary for decision-makers to address gaps in climate science and services for health: 2023 State of Climate Services for Health Companion Document
2023
Fueled by climate change, more frequent extreme weather events and drastic environmental changes have a fundamental impact on human health and well-being. Tailored climate products and services can serve as a powerful part of the public health toolkit – enhancing our ability to detect, monitor, predict, and manage climate related health risks. Among other targets, the draft COP28 Declaration on Climate and Health calls for improving the ability of health systems to anticipate, and implement adaptation interventions against, climate-sensitive disease and health risks, including by bolstering climate-health information services, surveillance, early warning and response systems and a climate-ready health workforce. The 2023 WMO State of Climate Services for Health Report and the WHO-WMO Implementation Plan for Advancing Integrated Climate, Environment and Health Science and Services (2023-2033) outline the current gaps and barriers that must be urgently addressed to enhance the climate resiliency of the health sector. This summary outlines critical investment areas to address the gaps in Climate Science and Services for Health.
Considerations Regarding the Naming of Heatwaves
2022
The World Meteorological Organization (WMO) plays a central role in the global coordination of the naming of extreme weather events. International experts in public health, public policy, and meteorology were consulted to assess the advantages and disadvantages of naming heatwaves being piloted in several countries. At SERCOM-2 (Oct 2022), WMO Members considered the practice of naming heatwaves, and expressed caution in adopting or promoting this practice. Members requested WMO to focus attention on strengthening heat-health warning systems, enhancing technical heat forecasting capabilities, and building capacity and partnerships to protect vulnerable communities from extreme heat. Key findings are summarized in this Technical Brief.
Final Report: From the G7 Health Communiqué to Action: Health and Climate – Heat Preparedness through Early Warning Systems
2022
The G7 event “From the G7 Health Communiqué to Action – Health and Climate: Heat Preparedness through Early Warning Systems” on 29 November 2022 recognized the importance of scaling up and enhancing Heat Health Warning Systems (HHWSs) and corresponding policy actions as key instruments for building resilience to climate variability and change in the health sector. This report captures the expert discussions during the event on the state of implementation, opportunities, challenges and advances in protecting communities from increasing extreme heat. Its conclusions allow the G7 countries to learn from each other and share important lessons with the broader global community. This report has been prepared by the WMO – WHO Joint Office for Climate and Health in close coordination with the German Federal Ministry of Health in the context of Germany’s G7 presidency and the health and climate event as part of the G7 Health Track. The report will serve as a contribution to the Global Heat Health Information Network (GHHIN).

Reporting on Heatwaves and the Health Impacts of Heat
2023
Media representations of heatwaves and climate change plays an important role in how the public thinks about, perceives, prepares for and acts on risks to their health, and how decision and policy makers address the problem. This brief was developed by the Global Heat Health Information Network and partners to provide journalists, editors and others working in the media and communications sector with guidance and perspectives on how extreme heat and heat health narratives and imagery can help save lives and drive action.
“Fan-First” Cooling – a low-carbon way to improve heat resilience in a changing climate
2023
Mitigating climate change is vital, but inevitable rising temperatures means that identifying sustainable cooling strategies is also important. Strategies at the individual scale that focus on cooling the person instead of the surrounding air can be effectively adopted, even in low-resource settings. This report presents the evidence behind “Fan-First” cooling as a low-carbon approach to improving heat resilience.
