Climate denialists – 23 in Senate and 100 in House – are all Republicans and make US an outlier internationally

US politics is an outlier bastion of climate denial with nearly one in four members of Congress dismissing the reality of climate change, even as alarm has grown among the American public over dangerous global heating, an analysis has found.

A total of 123 elected federal representatives – 100 in the House of Representatives and 23 US senators – deny the existence of human-caused climate change, all of them Republicans, according to a recent study of statements made by current members.

“It’s definitely concerning,” said Kat So, campaign manager for energy and environment campaigns at the Center for American Progress, who wrote the report.

The report defined climate deniers as those who say that the climate crisis is not real or not primarily caused by humans, or claim that climate science is not settled, that extreme weather is not caused by global warming or that planet-warming pollution is beneficial.
