President Donald Trump’s administration on Tuesday proposed revoking a scientific finding that has long been the central basis for U.S. action to regulate greenhouse gas

The proposed rule would rescind a 2009 declaration that determined that carbon dioxide and other greenhouse gases endanger public health and welfare.

The Trump administration plans to revoke the EPA’s 2009 “endangerment finding,” a key legal basis for US climate regulations, sparking backlash from scientists, environmentalists, and former EPA officials.
