"Climate skeptics are gaining ground.
"There's always been a vocal subset of conservatives who cast doubt on climate science, but what were once fringe views among broader Republicans — like warming's a hoax — are enjoying a growing acceptance in the GOP, worrying academics, scientists and sociologists.
" 'They have taken over the [U.S.] EPA," Naomi Oreskes, a professor of the history of science at Harvard University who has studied climate denier groups extensively, said in an email. "A very sad state of affairs."
"The groups sowing climate doubt are more emboldened than ever before, sociologists and historians said. Their effectiveness in the era of President Trump is a reflection of a deepening polarization in U.S. politics and a normalization of climate skepticism on the right, they said.
"Democrats and Republicans have never been further apart on climate change, according to public opinion polling released last week by Gallup.
"The results illuminate the anti-science sentiment within the GOP. The poll found that 82 percent of Democrats believe global warming has already begun compared with 34 percent of Republicans (Climatewire, March 28).
"That rift has contributed to major differences between the Republican administrations of Trump and former President George W. Bush, said Riley Dunlap, an environmental sociologist at Oklahoma State University. Bush's government internalized climate skeptics, but the groups scoring victories were largely silent when policies went their way. Now, however, those same organizations like the Heartland Institute and the Competitive Enterprise Institute boldly proclaim success — and then push even further.
" 'It's like they sense victory. They are proclaiming victories, and they keep pushing," Dunlap said. "This extreme radicalization of the Republican Party means they don't have to hide it. They don't have to dress it up like Bush 43 did. They can be in-your-face deniers.' " . . .
