The article is about comparable losses.

It may exceed 2005 to take second place. August 1/2 and August 6/7 had additional melt but they've both been followed by slower losses (cloudy weather). The forecast of ice-free within five years is reasonable - it's only going to take one hot summer to finish off the thin cover. But this summer won't equal last summer unless there is a freak weather event, imo.Owlhttps://www.blogger.com/profile/04553304856876679139noreply@blogger.comtag:blogger.com,1999:blog-579549341020421678.post-5018210934881966962008-08-11T10:26:00.000-05:002008-08-11T10:26:00.000-05:00Sorry, the post of Sunday, August 10, has the upda...Sorry, the post of Sunday, August 10, has the updated graphics and satellite photos.Anonymousnoreply@blogger.comtag:blogger.com,1999:blog-579549341020421678.post-87135230921966586442008-08-11T10:24:00.000-05:002008-08-11T10:24:00.000-05:00Dear FredT,Thank you for your comment.

That cool spell is over, and if the warm air from northwestern Canada and Siberia continues to work its way into the Arctic Sea area, that thin ice is going to disappear very quickly -- well, it already is, the melt over the last two or three days has been incredible. See my updated post on the melt (August 9 post).<BR/><BR/>Best,<BR/><BR/>TenneyAnonymousnoreply@blogger.comtag:blogger.com,1999:blog-579549341020421678.post-5947785624568558312008-08-11T10:00:00.000-05:002008-08-11T10:00:00.000-05:00Hi Tenney,More on this (sudden) (unexpected?) acce...Hi Tenney,<BR/><BR/>More on this (sudden) (unexpected?) acceleration here : http://www.canada.com/ottawacitizen/story.html?id=a6475b46-616e-4003-84d7-f8e4e9a18060<BR/><BR/>The Canadian Ice Service is reporting an "unprecedented" opening of waters in the Beaufort Sea north of the Yukon-Alaska border, where expected increases in ship traffic have just prompted the U.S. Coast Guard to establish two new outposts on Alaska's north coast to strengthen its vessel-monitoring and search-and-rescue capabilities.<BR/><BR/>"We've never seen any kind of opening like this in history," senior ice forecaster Luc Desjardins said of the Beaufort's exceptional loss of ice this summer. "It is not only record-setting, it's unprecedented. It doesn't resemble anything that we've observed before."<BR/><BR/>Mr. Desjardins says there's also a "very good likelihood" that the best-known route of the Northwest Passage -- from north of Baffin Island to the Beaufort Sea south of Victoria Island -- will soon become fully navigable for the third consecutive summer, a year after the fabled shipping conduit drew global attention by opening more completely than ever.<BR/><BR/>"It takes less solar energy to dissipate and melt that ice," says Mr. Desjardins. "So we potentially could reach a new minimum. Time will tell if we are going to be approaching the 2007 sea-ice retreat -- there still five weeks (of melting) to go."<BR/><BR/>I'm trying to reach a complete source for this, without success so far.<BR/><BR/>FredFredThttps://www.blogger.com/profile/06287449380897149179noreply@blogger.com
