Representative Jim Bridenstine (R-OK) was sworn in as NASA administrator in April, after facing criticism over his past skepticism of anthropogenic climate change. During a Wednesday meeting of the Senate Appropriations Subcommittee, however, Bridenstine conceded to Senator Brian Schatz (D-HI) that his viewpoint has evolved, and he no longer disputes “that human activity is the dominant cause of global warming.”

“I have no reason to doubt the science that comes from that,” he said.
