Climate and Health

The Climate and Health Program studies how climate change harms people's health in Wisconsin and develops ways to reduce those health impacts with local partners. We also use our research to create strategies, tools, and trainings to help communities adapt to climate change and protect the health and well-being of all Wisconsinites. To learn how climate impacts our health and hear real stories of Wisconsinites impacted by climate change, watch four short videos.
