Arctic ice refuses to melt as ordered!!!

“Just a few weeks ago, predictions of Arctic ice collapse were buzzing all over the internet. Some scientists were predicting that the "North Pole may be ice-free for first time this summer". Others predicted that the entire "polar ice cap would disappear this summer".

“The Arctic melt season is nearly done for this year. The sun is now very low above the horizon and will set for the winter at the North Pole in five weeks. And none of these dire predictions have come to pass. Yet there is, however, something odd going on with the ice data.

“The National Snow and Ice Data Center (NSIDC) in Boulder, Colorado released an alarming graph on August 11, showing that Arctic ice was rapidly disappearing, back towards last year's record minimum. Their data shows Arctic sea ice extent only 10 per cent greater than this date in 2007, and the second lowest on record (see link below to view graphs).

However, a comparison of maps derived from NSIDC data shows that “Arctic ice extent was 30 per cent greater on August 11, 2008 than it was on the August 12, 2007. (2008 is a leap year, so the dates are offset by one.) 

"... ice has grown in nearly every direction since last summer - with a large increase in the area north of Siberia. Also note that the area around the Northwest Passage (west of Greenland) has seen a significant increase in ice. Some of the islands in the Canadian Archipelago are surrounded by more ice than they were during the summer of 1980. 

“(The NSIDC graph) appears to disagree with the maps by a factor of three (10 per cent vs. 30 per cent) - hardly a trivial discrepancy.

“The Arctic did not experience the meltdowns forecast by NSIDC and the Norwegian Polar Year Secretariat. It didn't even come close. Additionally, some current graphs and press releases from NSIDC seem less than conservative. There appears to be a consistent pattern of overstatement related to Arctic ice loss.

And what of the Antarctic? Down south, ice extent is well ahead of the recent average. Why isn't NSIDC making similarly high-profile press releases about the increase in Antarctic ice over the last 30 years?
