Abstract:Chapter 7 of the IPCC Sixth Assessment Report (AR6),Working Group II (WG II),entitled'Health,well-being and the changing structure of communities’,assessed the current impacts and projected risks of climate change on health and well-being,and proposed strategies and constraints for health adaptation.Evidence has increased since AR5 that climate change has had negative impacts on human physical health,including mental health,through direct or indirect way,and that climate-sensitive diseases,malnutrition,premature death,and threats to mental health are increasing,and that climate-related hazards are increasingly affecting a growing number of health outcomes (including communicable and non-communicable diseases) and geographical areas.Cascading and compounding risks affecting health due to extreme weather events have been observed in all regions and risks are expected to increase with further warming.Key adaptation measures for health risks include increasing investment in health and other systems,strengthening integration and collaboration across sectors and systems,building climate-resilient development pathways,and integrating adaptation and mitigation in the goal of sustainable development and so on,which will bring huge co-benefits for health and well-being.
