Arctic Sea Ice Underestimated for Weeks Due to Faulty Sensor

Feb. 20 (Bloomberg) -- A glitch in satellite sensors caused scientists to underestimate the extent of Arctic sea ice by 500,000 square kilometers (193,000 square miles), a California- size area, the U.S. National Snow and Ice Data Center said.
The error, due to a problem called “sensor drift,” began in early January and caused a slowly growing underestimation of sea ice extent until mid-February. That’s when “puzzled readers” alerted the NSIDC about data showing ice-covered areas as stretches of open ocean, the Boulder, Colorado-based group said on its Web site.
“Sensor drift, although infrequent, does occasionally occur and it is one of the things that we account for during quality- control measures prior to archiving the data,” the center said. “Although we believe that data prior to early January are reliable, we will conduct a full quality check.’’
The extent of Arctic sea ice is seen as a key measure of how rising temperatures are affecting the Earth. The cap retreated in 2007 to its lowest extent ever and last year posted its second- lowest annual minimum at the end of the yearly melt season. The recent error doesn’t change findings that Arctic ice is retreating, the NSIDC said.
The center said real-time data on sea ice is always less reliable than archived numbers because full checks haven’t yet been carried out. Historical data is checked across other sources, it said.
The NSIDC uses Department of Defense satellites to obtain its Arctic sea ice data rather than more accurate National Aeronautics and Space Administration equipment. That’s because the defense satellites have a longer period of historical data, enabling scientists to draw conclusions about long-term ice melt, the center said.
“There is a balance between being as accurate as possible at any given moment and being as consistent as possible through long time-periods,” NSIDC said. “Our main scientific focus is on the long-term changes in Arctic sea ice.”

Al Gore is AN indiot...
Believe what you want, the guy knew what he was doing... Flying from city to city in his private Jet, driving his big SUV, telling people the world was ending, and making millions of dollars doing it. He invested millions in "Green" technology companies, and after he went around saying the sky was falling, people bought into it and went green. Now all that money he invested is worth millions more, because these green companies have skyrocketed in sales, and profits.
He's not an idiot, he's just a sleazy SOB who used his political power (he did still have power, after all, he did win the popular vote) to make money with spreading a few words where the truth was stretched... Or broken, depends on how you look at it.
