New CNN poll: Belief in the global warming hoax is down 7 points from 2007

CNN Poll: Do Americans agree with Obama on climate change and immigration? – CNN Political Ticker - CNN.com Blogs

According to the poll, 49% agree with the White House that global warming is a proven fact and is due to emissions from cars, power plants and factories. That's twice as high as the number who say that global warming has not been proven, as well as the 24% who say that it is a proven fact but is not due to manmade sources. But the 49% figure is down seven points from 2007.

There's an expected partisan divide on the question, with two-thirds of Democrats saying global warming is man made. That number drops to 48% among independent voters and is at 28% among Republicans.
