This Year’s Arctic Ice Melt 'Fascinating' and 'Alarming': Climate Scientists
According to a report in the Vancouver Sun, so much ice had melted by the end of August 2008 that it was possible for the first time in human history to circumnavigate the North Pole, prompting one prominent U.S. scientist to say that the ice cap has entered a "death spiral."
Though at one point, it looked like 2008 might shatter last year's retreat of ice, in the end, the ice cap survived for at least another year.
The U.S. National Ice and Snow Data Center is expected to issue its wrap-up report, which will confirm 2008's Arctic retreat as the second worst on record after 2007's stunning loss.
But, the ice that survived is in precarious shape heading into the winter.
Most of it is first-year ice less than a meter thick, according to Walt Meier, a research scientist at the U.S.-based centre, which tracks the ice by satellite as it waxes and wanes through the year.
Thick, multi-year ice used to cover much of the Arctic Ocean year-round. All that is left of that cement-like ice is now jammed up in a strip against Canada's Arctic islands and northern Greenland.
The rest of the old, hard ice either melted this summer or was flushed down into the Atlantic Ocean, where it disintegrated.
