Red Faces at NASA over Climate Change Blunder

In the United States, the calendar year 1998 ranked as the hottest of them all – until someone checked the math.

After a Toronto skeptic tipped NASA this month to one flaw in its climate calculations, the U.S. agency ordered a full data review.

Days later, it put out a revised list of all-time hottest years. The Dust Bowl year of 1934 now ranks as hottest ever in the U.S. – not 1998.

More significantly, the agency reduced the mean U.S. "temperature anomalies" for the years 2000 to 2006 by 0.15 degrees Celsius.

NASA officials have dismissed the changes as trivial. Even the Canadian who spotted the original flaw says the revisions are "not necessarily material to climate policy."

But the revisions have been seized on by conservative Americans, including firebrand radio host Rush Limbaugh, as evidence that climate change science is unsound.

Said Limbaugh last Thursday: "What do we have here? We have proof of man-made global warming. The man-made global warming is inside NASA ... is in the scientific community with false data."
