"WASHINGTON — Once a skeptic about climate change, Jim Bridenstine came around to the prevailing view of scientists before he took over as NASA administrator. That evolution did not sit well with a Trump environmental adviser, nor a think-tank analyst he was consulting, according to newly disclosed emails that illustrate how skepticism of global warming has found a beachhead in the Trump White House.

“Puzzling,” says the May 2018 exchange between William Happer, now a member of President Donald Trump’s National Security Council, and Thomas Wysmuller of the Heartland Institute, which disavows manmade climate change. Their exchange calls scientifically established rises in sea levels and temperatures under climate change “part of the nonsense” and urges the NASA head — who was copied in — to “systematically sidestep it.”

It cannot be discerned whether it was Happer or Wysmuller who put that pressure on the new NASA chief. Their exchange is included in emails from 2018 and 2019 that were obtained by the Environmental Defense Fund under the federal Freedom of Information Act and provided to The Associated Press.

But the emails show that Happer, who was then advising Trump’s Environmental Protection Agency, kept up the pressure after he joined the National Security Council late last year."
