Climate Change and Human Well-Being in the 2020s: Lessons From 2020.

Behind the coronavirus headlines the year 2020 set multiple extreme weather records, including unprecedented wildfires in Australia and California, massive flooding in China, and back-to-back hurricanes in Central America. The impacts on the well-being of local populations have been devastating. We reviewed these extreme weather events, together with the year's newly published climate and health science reports, and identified three important themes for building health resilience in the decade ahead: (1) preparing for greater magnitude and intensity of climate hazards, extreme events, and population health impacts; (2) better anticipating cascading and compound impacts on population well-being, particularly for the most vulnerable; and (3) identifying appropriate, effective preparedness tools and strategies. While decarbonizing the economy is the urgent goal to protect both human and planetary health from a changing climate, 2020 demonstrates that recognizing the likely magnitude and complexity of future extreme weather events, and preparing local public health agencies and communities with the knowledge and tools to respond to them, will be essential in this critical decade.
