From Forbes Magazine: NASA scientist James Hansen has gotten lots of attention for his claim that most of the ten hottest years have occurred since 1990. However, a blogger (not me) recently discovered an error in those calculations, which has put the heat on NASA. The space agency now claims that:
- The hottest year on record was 1934, not 1998
- The third hottest year was 1921, not 2006
- Three of the five hottest years on record occurred before 1940
Thus while global warming might still be a problem, the warming trend apparently started before the real expansion of human caused carbon dioxide emissions. And if humans didn't cause global warming, it's not clear how much they can do to stop it.
