The GOP is divided on global warming, as seven in 10 Tea Party Republicans believe there's no solid evidence of a warming planet compared with three in 10 non-Tea Partiers, according to a Pew Research poll released Friday.
Overall, 46 percent of Republicans said there is no solid evidence of global warming, compared with 11 percent of Democrats.
Of those who see solid evidence of global warming, Republicans were nearly three times less likely (23 percent) to attribute it to human activity than Democrats (64 percent). That difference was more pronounced among Tea Partiers, 9 percent of whom said humans play a role in climate change compared with 32 percent of non-Tea Partiers.
Such beliefs are at odds with the overwhelming scientific consensus that burning fossil fuels are a major contributor to greenhouse gas emissions that drive climate change.
The U.N. Intergovernmental Panel on Climate Change released a report in September that said scientists have 95 percent confidence — the same confidence rate for the finding that smoking causes cancer — that humans contribute to global warming.
But many congressional Republicans remain skeptical, or deny, that climate change is occurring.
The poll of 1,504 people between Oct. 9-13 from left-leaning Pew showed those attitudes stretch beyond Capitol Hill.
Overall, the poll said 67 percent of respondents believed there is solid evidence that global warming is happening. The split was 84 percent of Democrats and 46 percent of Republicans. The percentage of non-Tea Party Republicans who believed global warming was occurring was 61 percent.
