Learn How Climate Change Harms Health

Some existing health threats will intensify, and new health threats will emerge.

Overview

Climate change harms health in many ways. Increasing numbers of hot days may mean more heat-related illnesses and heart attacks. Poor air quality from air pollution on hot days and more pollen in the air increases the risk of asthma attacks.  Mosquito-borne diseases may increase as the climate continues to become wetter and warmer. More extreme storms can cause property damage, flooding, and loss of homes and businesses. 

While climate change affects everyone, it most heavily affects the health of people who are experiencing chronic health conditions and disabilities, social and/or economic disadvantages, and environmental exposures.
