The percentage of Americans who believe global warming is happening has dipped from 80 to 72 percent in the past year, according to a new Washington Post-ABC News poll, even as a majority still support a national cap on greenhouse gas emissions. he poll's findings -- which also show that 55 percent of respondents think the United States should curb its carbon output even if major developing nations such as China and India do less -- suggest increasing political polarization around the issue, just as the Obama administration and congressional Democrats are intensifying efforts to pass climate legislation and broker an international global warming pact.
The increase in climate skepticism is driven largely by a shift within the GOP. Since its peak 3 1/2 years ago, belief that climate change is happening is down sharply among Republicans -- 76 to 54 percent -- and independents -- 86 to 71 percent. It dipped more modestly among Democrats, from 92 to 86 percent. A majority of respondents still support legislation to cap emissions and trade pollution allowances, by 53 to 42 percent.
Amanda Feinberg, a retired administrative assistant living in South Williamsport, Pa., said she became disenchanted with the idea of human-caused global warming when former vice president Al Gore launched a public awareness campaign with his documentary, "An Inconvenient Truth."
"He just seemed a little radical in his views," said Feinberg, a Republican. "I don't deny it's happening, I just think it's just an evolution of nature."
Lisa Woolcott, another Republican poll respondent, said she doesn't think that burning fossil fuels is "causing all the global warming," adding: "We can't control what happens in the atmosphere." But Woolcott, a physician's assistant who lives in Kansas City, Kan., said she supports the idea of a bill that would cap the nation's greenhouse gas emissions and doesn't think the United States should predicate its actions on what other nations do. "We need to do what's best for us," she said. "I don't think we should back down."
