 This paper summarizes the results of 94 systematic reviews on the health impacts of climate change. The majority of the reviews focused on the effects of extreme weather events, such as floods, droughts, heatwaves, and hurricanes, on various health outcomes, such as infectious diseases, respiratory, cardiovascular, and neurological conditions. The majority of the reviews concluded that climate change is associated with worse health outcomes, but further research is needed to understand the underlying mechanisms and identify effective adaptation and mitigation strategies.
