We have good news and bad news from a CNN national poll released yesterday.

The bad news is that two-thirds of Americans still believe global warming (GW) is a proven fact.
But the good news is that the number of believers is down 8 points since June of 2008, which means that Americans are getting increasingly skeptical about GW. 
What is interesting is that the rise in skepticism is mostly due to changes among Republicans. Compared to last June, the number of Republican GW believers has dropped 11 points, while the number of Democrat GW believers is holding steady.
More interesting still is the fact that the shifts in views on global warming have been going on for several months, predating the hacked U. of East Anglia e-mails. This means that, once more Americans know about the content of the hacked e-mail, they are likely to be even more skeptical about global warming!

About a third of the people who believe in global warming think it is due to natural causes, rather than manmade causes such as industrial emissions. As a result, the number who say that global warming is caused by humans has dropped from 54% last summer to 45% now. The number who say the U.S. should reduce emissions even if other countries do not follow suit has also dropped, from 66% in 2007 to 58% today.

The CNN/Opinion Research Corporation poll was conducted December 2-3, with 1,041 adult Americans questioned by telephone. The survey’s sampling error is plus or minus 4.5 percent for the overall sample.
