ABC News reports:
In a Pew poll in early September 2005, shortly after Hurricane Katrina, just a quarter of Americans thought climate change likely was responsible for its severity. Two-thirds said it was more likely “just the kind of severe weather that happens from time to time.”
As the storm’s impact became clear, more, 39 percent, blamed climate change just weeks later, and this moved to a near-even 45-49 percent by 2006. It’s flipped entirely in the ensuing decade: In this poll, produced for ABC by Langer Research Associates, 55 percent mainly blame climate change, vs. 41 percent happenstance.
The shift is highly partisan. Seventy-eight percent of Democrats, whose party made combating climate change part of its 2016 election platform, mainly blame climate change for hurricane severity, a 47 percentage-point increase from 2005. So do 56 percent of independents, a 27-point increase.
By contrast, after an 8-point bump in the weeks following the devastation of Katrina, there’s been essentially no change among Republicans, with about a quarter blaming climate change in late September 2005, 2006 and 2017 alike.
