Climate Change and Public Health

Data and Fact Sheets

"Climate change, together with other natural and human-made health stressors, influences human health and disease in numerous ways. Some existing health threats will intensify and new health threats will emerge. Not everyone is equally at risk. Important considerations include age, economic resources, and location.

In the U.S., public health can be affected by disruptions of physical, biological, and ecological systems, including disturbances originating here and elsewhere. The health effects of these disruptions include increased respiratory and cardiovascular disease, injuries and premature deaths related to extreme weather events, changes in the prevalence and geographical distribution of food- and water-borne illnesses and other infectious diseases, and threats to mental health."

Key messages about public health and climate change:

1) Climate change disproportionately impacts the health of low-income communities and communities of color.

2) Climate change and health inequities share the same root causes.

3) Addressing climate change and health inequities requires transformational change in our systems and communities.
