Agency roasted after Toronto blogger spots `hot years' data fumble

STAFF REPORTER

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.

.

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."
