In retrospect, you knew there would be trouble when you put the people responsible for the Space Shuttle program in charge of tracking U.S. temperatures. So perhaps it shouldn’t have come as a big surprise when it was revealed that NASA committed a bit of an oopsie regarding data constantly used by the mainstream media and other global warming proponents.

If you follow the global warming debate, you “know” that nine of the ten warmest years recorded in the U.S. lower 48 since 1880 have occurred since 1995, with the very hottest being 1998.

But whaddya know! Those figures are wrong. Data from NASA’s Goddard Institute for Space Studies (GISS) now show the hottest year since 1880 was 1934. Nineteen-ninety-eight dropped to second, while the third hottest year was way back in 1921. Indeed, four of the 10 hottest years were in the 1930s, while only three were in the past decade.

The real 15 hottest years are spread over seven decades. Eight occurred before the chief “greenhouse gas,” atmospheric carbon dioxide, began its sharp rise; seven occurred afterwards.

Rush Limbaugh was incorrect in saying the new figures are “just more evidence” that “this whole global warming thing is a scientific hoax.” Conversely, global warming hotheads are also wrong in insisting the revelation belongs in a game of Trivial Pursuit.

The GISS, which is directed by global warming guru James Hansen, is saying likewise. They’re wrong, in part because of the importance of the data and in part because of what might be labeled a cover-up.

In pooh-poohing the revision, the GISS ignores the tremendous emotional impact it’s had in practically claiming each year is hotter than the one before. Instead it observes (correctly) since the U.S. accounts for merely two percent of global land surface, a relatively small adjustment in its figures doesn’t meaningfully impact the global picture.

But, notes Canadian mathematician Stephen McIntyre, who exposed the false figures, “The Hansen error . . . has a significant impact on the GISS estimate of U.S. temperature history . . .” (Emphasis added.) Is this important because we’re a major world power or that we produce the best fried chicken? No, it’s important because we have a far more sophisticated system of temperature monitoring than countries with far larger land masses. Hence, data from each of these nations affect the global model more than the American data.
