Bizarre Public Opinion Numbers on Global Warming

| Thu May 15, 2008 3:30 PM EDT

Roughly 70 percent of Americans believe there is "solid evidence" the earth is warming, according to new Pew poll numbers. Just under half think that warming is caused by human activity. That's disappointing — we've got more work to do, Mother Jones! — but not that surprising. On the other hand, try explaining this:

Over the last year and a half, the number of Americans who believe the Earth is warming has dropped. The decline is especially precipitous among Republicans: in January 2007, 62 percent accepted global warming, compared to just 49 percent now.

Or this!

...among college-educated poll respondents, 19 percent of Republicans believe that human activities are causing global warming, compared to 75 percent of Democrats. But take that college education away and Republican believers rise to 31 percent while Democrats drop to 52 percent.

Consider me stumped.
