The US administration under President Donald Trump is revoking a scientific finding that has been central to climate policy. The move, announced by EPA head Lee Zeldin, aims to dismantle regulations based on the 2009 endangerment finding. This decision, which would remove the EPA's authority to regulate greenhouse gases, has sparked concerns about a shift towards fossil fuel reliance. The EPA's proposal is open for public comment until September, with potential legal battles. Experts warn that the reversal could undermine climate efforts and lead to increased fossil fuel use. Despite the reversal, the EPA retains authority to regulate other pollutants, and states are still working on their own climate policies. The decision highlights the ongoing tension between federal climate regulation and political priorities.
