Warm Green Tea?

Thanks to The Economist for summarizing this Yale University data about climate change skepticism by political affiliation. 

It seems that compared to Democrats, Independents, and Republicans, the Tea Party is:

• Least likely to beleive in Global Warming
• Most likely to believe they are "very informed" about Global Warming
• Most likely to believe they need no more information about Global Warming

I think what's striking is the size of the differences here. 

~50% of Tea Partiers don't believe in global warming compared to just 30% of Republicans (and <15% of Independents/Democrats). 

~30% of Tea Partiers consider themselves "very informed" compared to <10% of any other affiliation. 

>50% of Tea Partiers think they have all the information they need to make an informed judgment about Global Warming compared to ~20% for all other affiliations. 

So not are they ignorant about Global Warming, they are convinced they know more than anyone else.

It would be hilarious if it weren't so pathetic.
