WASHINGTON ― President-elect Donald Trump said in an interview airing Sunday that “nobody really knows” the facts about climate change, even though there’s widespread scientific consensus on the issue.

“It’s not something that’s hard and fast,” Trump said on “Fox News Sunday.” “I do know this: other countries are eating our lunch.”

Trump said he’s “studying” the Paris agreement, a joint effort by nearly 200 countries to reduce greenhouse gas emissions.

“I don’t want that agreement to put us at a competitive disadvantage with other countries,” Trump said.

Trump met this week with Leonardo DiCaprio to discuss global warming, but also named Oklahoma Attorney General Scott Pruitt, a defender of fossil fuel interests, to head the Environmental Protection Agency.

Back in 2012, Trump tweeted that global warming “was created by and for the Chinese in order to make U.S. manufacturing non-competitive.”
