Key Scientific Findings on Greenhouse Gas Emissions

In September 2025, the National Academies of Sciences, Engineering, and Medicine jointly released a report condemning the Trump administration’s attempt to rescind the U.S. Environmental Protection Agency’s 2009 scientific findings that greenhouse gases pose a threat to public health. The Trump administration announced in July this year that it would begin revoking this “endangered findings” designation. The EPA Administrator claimed the economic damage from greenhouse gases appears less severe than anticipated, but the scientific community strongly disputes this assertion.
