In an announcement that could come as soon as Thursday or as late as next month, according to people familiar with the White House’s planning, Mr. Trump will order Mr. Pruitt to withdraw and rewrite a set of Obama-era regulations known as the Clean Power Plan, according to a draft document obtained by The New York Times. The Obama rule was devised to shut down hundreds of heavily polluting coal-fired power plants and freeze construction of new coal plants, while replacing them with vast wind and solar farms.
The draft also lays out options for legally blocking or weakening about a half-dozen additional Obama-era executive orders and policies on climate change.
At a campaign-style rally on Monday in the coal-mining state of Kentucky, Mr. Trump told a cheering audience that he is preparing an executive action that would “save our wonderful coal miners from continuing to be put out of work.”
Experts in environmental law say it will not be possible for Mr. Trump to quickly or simply roll back the most substantive elements of Mr. Obama’s climate change regulations, noting that the process presents a steep legal challenge that could take many years and is likely to end up before the Supreme Court. Economists are skeptical that a rollback of the rules would restore lost coal jobs because the demand for coal has been steadily shrinking for years.
Scientists and climate policy advocates around the world say they are watching the administration’s global warming actions and statements with deep worry. Many reacted with deep concern to Mr. Pruitt’s remarks this month that he did not believe carbon dioxide was a primary driver of climate change, a statement at odds with the global scientific consensus. They also noted the remarks last week by Mick Mulvaney, the director of the White House Office of Management and Budget, in justifying Mr. Trump’s proposed cuts to climate change research programs.
“As to climate change, I think the president was fairly straightforward: We’re not spending money on that anymore,” Mr. Mulvaney said at a White House briefing.
“The message they are sending to the rest of the world is that they don’t believe climate change is serious. It’s shocking to see such a degree of ignorance from the United States,” said Mario J. Molina, a Nobel Prize-winning scientist from Mexico who advises nations on…
