On July 29, per the New York Times, the Environmental Protection Agency said that the Trump administration would revoke the scientific determination that underpins the government’s legal authority to combat climate change.

The EPA Administrator, Lee Zeldin, said the E.P.A. planned to rescind the 2009 declaration, known as the endangerment finding, which concluded that planet-warming greenhouse gases pose a threat to public health.

This linked article, details four laws that could stymie the recission of the endangerment finding.  It was published on August 12 in The Conversation (a web-based network of nonprofit media outlets publishing news stories and research reports online, authored by academics with professional journalist editors to produce accessible research-informed outputs).

Also as stated in the July 29 NYT article, the proposed repeal of the endangerment finding would most certainly draw legal challenges (including those based on the laws in the linked article above). David Doniger, a senior attorney at the Natural Resources Defense Council, said he expected that it would eventually be struck down in court. He noted that climate science has advanced significantly since 2009, when the finding was issued.

After the proposal is published in the Federal Register, the E.P.A. will solicit comments from the public for 45 days, Mr. Zeldin said. The agency will then look to finalize the rule, most likely next year.
