All this was over a small
Can't see it? That's not surprising. James Hansen of NASA, who applied the corrections to both the U.S. and global data, writes:
The effect on global temperature (Figure 2) was of order one-thousandth of a degree, so the corrected and uncorrected curves are indistinguishable.More here. Bottom line: there's no there there. Global warming is still real, still climbing, and still not a hoax. Tell your friends.
UPDATE: It looks I might be guilty of passing along an urban legend here. It wasn't a Y2K bug that prompted the temperature corrections, it was a switch between two sources of US temperature data that happened to take place between 1999 and 2000. "There had been a faulty assumption that these two sources matched, but that turned out not to be the case," says Gavin Schmidt. More here.
