WASHINGTON (AP) — President Donald Trump’s administration has proposed revoking a scientific finding that’s long been the central basis for U.S. action to regulate greenhouse gas emissions and fight climate change. The proposed Environmental Protection Agency rule rescinds a 2009 declaration that determined carbon dioxide and other greenhouse gases endanger public health. The “endangerment finding” is the legal underpinning of a host of climate regulations under the Clean Air Act for motor vehicles, power plants and other pollution sources. EPA Administrator Lee Zeldin announced the proposed rule change on a podcast ahead of an official announcement set for Tuesday in Indiana. Three former EPA leaders say Zeldin’s proposal would endanger the lives of millions of Americans.
