Dr. Katharine Hayhoe

Since the United States Environmental Protection Agency issued its Endangerment Finding in 2009, the scientific evidence connecting greenhouse gas emissions to health impacts from climate change has only grown stronger.

Over the past two decades, I’ve contributed to this body of research myself: quantifying the risks posed by rising CO₂ levels to people, infrastructure and the natural systems we depend on, and authoring multiple U.S. National Climate Assessments.

These authoritative and exhaustive reports helped build the scientific foundation that underpins the Endangerment Finding, and their conclusions weren’t based on ideology. They were rooted in rigorous, peer‑reviewed evidence; evidence that has only become clearer with time.

Research today shows that climate change is increasing the risk of allergies, dementia, fertility, heart disease, mortality and so much more. Maintaining science‑based policies isn’t just prudent—it’s the reliable foundation we need to build a safer, healthier and more resilient future.

There is No Scientific Justification to Revoke the Endangerment Finding

The U.S. EPA's decision to repeal the Endangerment Finding will limit the government's ability to regulate emissions of carbon dioxide and other greenhouse gases under the Clean Air Act.

@kathhayhoe This roll back of scientifically proven climate changes is just more cronyism and naive denialism that will further imperil both the country and the world.

@kathhayhoe Thank you for your work on the NCA reports. I've used them in my career to support Hazard Mitigation planning, although that is being defunded and cited as 'wasteful' even though studies sponsored by #FEMA show that for every dollar invested in resiliency, another six are saved.
