From USA TODAY.

The Trump administration is preparing to rescind an Obama-era scientific finding that has served as the legal underpinning for federal regulations targeting greenhouse gases for more than a decade.

In a major blow to federal efforts to combat climate change, the Environmental Protection Agency will take action on Feb. 12 to repeal what’s known as the "endangerment finding," White House press secretary Karoline Leavitt said at a Feb. 10 briefing with reporters.

The EPA’s endangerment finding, signed in 2009 during the Obama administration, says current and projected concentrations of six key greenhouses gases in the atmosphere "threaten the public health and welfare of current and future generations." A related EPA finding, signed in tandem, singles out new motor vehicles and engines as contributors to greenhouse gas pollution.

The action, a potential boon for the fossil fuel industry, marks the most sweeping step the Trump administration has taken to roll back federal regulations targeting climate change, which President Donald Trump regularly mocks as a "hoax" and a "con job." Trump has also withdrawn the United States from global efforts to fight climate change.
