EPA Endangerment Finding Reversal Threatens Climate Data Infrastructure

The EPA's proposal to repeal its 2009 Endangerment Finding threatens to dismantle the technical foundation for federal climate regulation. Analysis of recent climate disasters shows economic impacts exceeding $75 billion from single events, yet the EPA's reversal would eliminate the legal basis for emissions measurement and regulation. Technical experts warn this creates systemic uncertainty in climate data collection systems that both research institutions and investment firms rely on for modeling future scenarios.
