And the dreaded “hockey stick” diagram is as stupid as it sounds? Wow…

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.

It was hotter 73 years ago than it is now… shall we go look at sunspot records for that time frame now? Or should we play it safe and see if there was an excess of cow flatulance that year?

Puzzled by a bizarre “jump” in the U.S. anomalies from 1999 to 2000, McIntyre discovered the data after 1999 wasn’t being fractionally adjusted to allow for the times of day that readings were taken or the locations of the monitoring stations.

McIntyre emailed his finding to NASA’s Goddard Institute, triggering the data review.

“They moved pretty fast on this,” McIntyre said. “There must have been some long faces.”

I expect Al Gore’s face won’t get any longer. He’ll either ignore the corrections, or excuse them somehow.
