WASHINGTON — The Trump administration on Thursday will revoke a scientific finding that long has been the central basis for US action to regulate greenhouse gas emissions and fight climate change, the White House announced. The Environmental Protection Agency will issue a final rule rescinding a 2009 government declaration known as the endangerment finding. That Obama-era policy determined that carbon dioxide and other greenhouse gases endanger public health and welfare. …White House press secretary Karoline Leavitt said… the action “will save $1.3 trillion in crushing regulations,” she said. …The endangerment finding is the legal underpinning of nearly all climate regulations under the Clean Air Act for motor vehicles, power plants and other pollution sources that are heating the planet. It is used to justify regulations, such as auto emissions standards, intended to protect against threats made increasingly severe by climate change — deadly floods, extreme heat waves, catastrophic wildfires and other natural disasters.
