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.
