William Happer, a Princeton scientist who is doubtful of the dangers of climate change, appears to be leading a White House challenge to the government’s conclusion that global warming is a threat. Twenty five years ago, William Happer had an encounter with the White House that ended badly. At the time, in 1993, the Princeton professor was taking a break from academia to direct scientific research at the U.S. Department of Energy. He turned a skeptical eye toward one of then-Vice President Al Gore’s favorite issues: the risks posed by chemicals eating away at ozone in the stratosphere and letting in dangerous ultraviolet radiation. As the story goes, Happer went to the White House and told Gore’s staff he saw no evidence that the ozone hole actually was hurting anyone. Gore was annoyed, and Happer lost his job. Today, Happer is back in the White House, still fighting against what he considers unfounded claims that our globe is in danger. But this time, his cause is backed by the man in the Oval Office. Happer, 79, joined the staff of President Trump’s National Security Council last fall. And according to documents first leaked to The Washington Post, he appears to be pushing the White House to mount a challenge to the government’s official assessment of climate change, which calls climate change a serious national security threat. On Thursday, the chairs of four different committees in the House of Representatives sent a letter to President Trump expressing concern about “recent reports that the National Security Council (NSC) is planning to assemble a secret panel, led by a discredited climate change denier, to undermine the overwhelming scientific consensus on the nature and threats of climate change.” The four Democrats called it “deeply concerning that Dr. Happer appears to be spearheading” that effort.
