Trump has not yet responded to Liu’s statement.
The panel originated in 1988 through a joint effort by the U.N. Environmental Program and the World Meteorological Organization when Reagan was in office. It has since published five comprehensive assessment reports that use findings from climate experts around the world to generate what its website calls a “full scientific and technical assessment of climate change.”
The panel was jointly awarded the Nobel Peace Prize in 2007, along with Al Gore, after releasing its fourth assessment.
Trump’s now-infamous tweet resurfaced during the first presidential debate on Sept. 26 when Democratic nominee Hillary Clinton confronted Trump over his claim, although she did not explicitly mention his tweet.
“Donald thinks that climate change is a hoax perpetrated by the Chinese,” Clinton said. “I think it’s real.”
Trump responded: “I did not. I did not. I do not say that.”
Trump has also questioned the existence of global warming multiple times since his November 2012 tweet, calling it “bulls—” and claiming cold weather had forced “hoaxsters” to relabel global warming as climate change.
Trump has also said he will get rid of the EPA and pull the United States out of the 2015 Paris climate agreement, which scientists say would have major global ramifications. The D.C.-based think tank Climate Interactive told The Post’s Chris Mooney that the U.S. emissions reduction pledge would account for more than 20 percent of the combined emissions cut among all countries in the accord.
Secretary of State John F. Kerry, who helped negotiate the Paris accord, said at the Marrakesh U.N. talks that the outgoing Obama administration plans to fight Trump’s intent to withdraw.
“No one has a right to make decisions for billions of people based solely on ideology,” Kerry said, via Bloomberg News. “Climate change shouldn’t be a partisan issue. It isn’t a partisan issue for our military. It isn’t a partisan issue for our intelligence community.”
In his speech, Kerry also appealed to Trump not to make decisions based only on ideology or “without proper input.”
“I ask you on behalf of billions of people around the world,” he said. “Do your own due diligence before making irrevocable choices.
