NASA

+ - Global Warming Debate Overheats with Bad Numbers->

Submitted by Geoffreyerffoeg
Geoffreyerffoeg writes: In response to last week's discussion of a bug in global warming data that made 1934, not 1998, the hottest year on record, a post in the Wall Street Journal's "Numbers Guy" blog notes that the change is statistically meaningless. Guest columnist Keith Winstein writes, "[A]t least 12 years out of the last 127 can claim to be in a statistical tie for warmest in the U.S. ... 1934 and 1998 have been swapping (statistically insignificant) spots on the ranking for a number of years." It turns out the 0.02 degree Celsius change was actually far less than the 0.47 degree margin of error.
