After the warmest year in recorded history, a shocking number of congressional Republicans—more than 56 percent—continue to deny or question the science behind human-caused climate change. Here are the facts:

  • Ninety-seven percent of climate scientists agree that current human activity is contributing to the warming atmosphere and causing the global climate to change.
  • One hundred sixty-nine Republicans in the 114th Congress are on record questioning or denying the science behind climate change.
  • Fifty-three percent—or 131 members—of the House Republican caucus question or deny the science behind climate change.
  • Seventy percent—or 38 members—of the Senate Republican caucus question or deny the science behind climate change.

As Congress returns to the nation’s capital, the new Republican-controlled Congress has made it clear that it has no intention of prioritizing action on climate change. In fact, Senate Majority Leader Mitch McConnell (R-KY) and the new head of the Senate Environment and Public Works Committee, Sen. Jim Inhofe (R-OK), have vowed to stop the Environmental Protection Agency’s, or EPA’s, attempt to curb carbon pollution and slow the devastating effects of climate change.
