The Endangerment Finding Explained — and What It Means for Climate Adaptation
In episode 248 of America Adapts, host Doug Parsons is joined by Professor Mark Nevitt of Emory University School of Law to unpack the repeal of the Clean Air Act’s Endangerment Finding and what it means for climate governance in the United States. Long considered the legal backbone of federal climate regulation, its rescission raises fundamental questions about agency authority, the role of the courts, and the durability of federal climate policy. Mark explains the legal theory behind the repeal, how it intersects with Supreme Court precedent, and what likely comes next in federal court. The conversation also explores the practical implications of regulatory instability — from increased climate litigation to the shifting balance between federal, state, and local responsibility. For listeners working in adaptation, public policy, infrastructure, law, or risk management, this episode offers a clear look at how legal shifts at the federal level can reshape the broader climate landscape — and why adaptation efforts must continue regardless of political volatility.
