Trump revokes US scientific finding behind climate change regulations
Overview
On Thursday the Trump administration issued a final rule rescinding the 2009 EPA endangerment finding that greenhouse gases endanger public health and welfare, the White House announced.
The 2009 finding, adopted under the Obama administration, has underpinned Clean Air Act regulations and followed the 2007 Supreme Court decision that greenhouse gases are air pollutants.
Experts, former officials and environmental groups condemned the move, with Gina McCarthy calling it "reckless" and Earthjustice saying it will challenge the administration in court.
The EPA projects the action will save $1.3 trillion and more than $2,400 per vehicle, while researchers cite over 29,000 peer-reviewed climate-health studies.
Legal challenges are certain, with Earthjustice and other advocates pledging court fights and states weighing responses while the National Academies concluded the 2009 science remains accurate and reinforced.
Analysis
Center-leaning sources frame the rollback as a dangerous, broadly condemned reversal, foregrounding Obama's warning and environmental and public‑health groups' objections (e.g., American Lung Association), while highlighting Trump's dismissive rhetoric and industry ties. Language like 'major blow' and 'sweeping step' plus selective emphasis on scientists creates an urgent, critical narrative.
