The Trump administration just rescinded the EPA's 2009 endangerment finding—eliminating the scientific and legal basis for all federal climate regulations under the Clean Air Act. This unprecedented rollback strips the EPA of its authority to regulate greenhouse gas emissions, threatening public health and our planet's future. The endangerment finding was established on solid peer-reviewed science showing that greenhouse gases endanger public health and welfare. It has been defended in court repeatedly. The evidence has only grown stronger since 2009—but the new EPA leadership is ignoring science to serve fossil fuel industry donors who poured millions into Trump's campaign. This is corruption disguised as deregulation. While the administration claims economic benefits, experts warn of trillions in climate damages and soaring healthcare costs. Vulnerable communities will suffer most. Our children deserve better than a future sacrificed for corporate profits. Congress must use every tool available—oversight hearings, legislation, and budget authority—to defend science-based climate protections. The EPA exists to protect Americans, not polluters. Demand Congress take immediate action to preserve the endangerment finding and restore the EPA's mission to protect public health and the environment.
