In a new poll (PDF), CNN asked the following question:
Which of the following statements comes closest to your view of global warming:
- Global warming is a proven fact and is mostly caused by emissions from cars and industrial facilities such as power plants and factories
- Global warming is a proven fact and is mostly caused by natural changes that have nothing to do with emissions from cars and industrial facilities
- Global warming is a theory that has not yet been proven

Those most likely to understand the connection are those who oppose the Tea Party, Democrats, those from the Northeast, non-whites, younger and middle-aged Americans, and women.
Here are they key results:
