Brad Plumer reads through a new study showing that views on climate change correlate with local weather. The study finds that:
"For each three degrees that local temperature rises above normal, Americans become one percentage point more likely to agree that there is 'solid evidence' that the earth is getting warmer."
Maybe this explains why national surveys that ask people whether they believe in global warming tend to fluctuate fairly significantly, even over a few short months' time.
Bonus finding: This local-weather effect is strongest on people who aren't particularly partisan, and it's pretty much non-existent for people who identify strongly with one party or the other. Committed Republicans tuning into Rush aren't likely to believe in man-made climate change no matter how sweaty it gets, while ardent Democrats won't stop listening to Al Gore just because there's a cold snap the day he's testifying before Congress. But for many people, however irrational, this stuff appears to have a fair-sized impact.
