There are climate deniers and climate believers, and among those there are many believers with religious zeal. I remain a climate skeptic--way too much politics involved for me to have any definitive views on the issue.
It was entertaining this past week watching all the climate faithful--most of whom weren't themselves climate scientists--bloviate about the recent report from NASA that last year was the hottest year ever (or on record or...); it was like listening to people panic about the future catastrophes we all know are before us due to global warming based on the fact that yesterday was the hottest day in the last twenty years in Washington D.C.
Well, it turns out that NASA's model has a margin of error that was not mentioned originally, so they can't even be certain that last year was a record year (let alone that if it were, this is any evidence for anything important).
