The #EndangermentFinding dates to 2009, when the #EPA concluded that planet-warming #GreenhouseGases pose a threat to #PublicHealth & so should be regulated under the #CleanAirAct. The #Obama & #Biden admins used that determination to set strict limits on greenhouse gas #emissions from cars, power plants & other industrial sources of #pollution.
But in July, the #Trump admin proposed to rescind the finding & contended that subsequent research had “cast significant doubt” on its accuracy.
