The Trump administration has moved to repeal the 2009 “endangerment finding” — the scientific determination that underpins the federal government’s authority to regulate climate change. The decision marks one of the most consequential climate policy shifts in years and sets up a major legal and political battle. POLITICO’s Jean Chemnick and Alex Guillén join host Nirmal Mulaikal to explain what the endangerment finding does, why it matters, and what happens next for U.S. climate policy.
