Climate Change and Human Health

Human health has always been influenced by climate and weather. Climate change, together with other natural and human-made health stressors, threatens human health and well-being in numerous ways.

Given that the impacts of climate change are projected to increase over the next century, certain existing health threats will intensify and new health threats may emerge. Connecting our understanding of how climate is changing with an understanding of how those changes may affect human health can inform decisions about mitigating (reducing) the amount of future climate change, suggest priorities for protecting public health, and help identify research needs.
