Arctic meltdown could set new record
It's now a "neck-and-neck race between 2007 and this year over the issue of ice loss," Mark Serreze, a senior climate researcher at the Colorado-based NSIDC, told the U.K.'s Guardian newspaper on Sunday. "We thought Arctic ice cover might recover after last year's unprecedented melting - and indeed the picture didn't look too bad last month."
But recent storms in the Beaufort region "triggered steep ice losses," he said, "and it now looks as if it will be a very close call indeed whether 2007 or 2008 is the worst year on record for ice cover over the Arctic."
The Canadian government's chief observers of Arctic ice conditions are expressing amazement at the state of the Beaufort Sea.
"We've never seen any kind of opening like this in history," CIS 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."
The persistent retreat of polar sea ice in recent years has convinced some researchers that the region is fast approaching a "tipping point" that could see nearly the entire Arctic ice-free during the summer months as early as 2013.

Who Needs Computer Models?
One of the more annoying points deniers try to make, is this idea that most of the science of global warming is based on computer models. It seems a convenient way to sideswipe the evidence, "I'm not putting any stock in some computer program". In an indirect way, the criticism has found some validity, the trouble is most of the "real world" evidence tends to find the computer models understate the rapidity of change, things are WORSE than the models predicted. That aside, this angle is mostly a diversion, because who needs models when you have reality:
