Extreme Heat

Resources and Research to Educate and Advocate for Change and Fight Against Heat

Climate change and the extreme heat it brings to our communities is a human-made problem. PSR’s Environment and Health Program has sounded the alarm for years about the fossil fuels that drive climate change, and we have helped the country change course toward a cleaner energy policy.

Thanks to our supporters, PSR created the resources below on the health hazards of extreme heat. Please use them to educate and advocate in your community for health and a livable climate.
