This latest New Scientist video accompanies a news item headlined “North Pole could be ice free in 2008“, and shows multi-year ice moving out of the Arctic over winter.
“The set-up for this summer is disturbing,” says Mark Serreze, of the US National Snow and Ice Data Center (NSIDC). A number of factors have this year led to most of the Arctic ice being thin and vulnerable as it enters its summer melting season.”
Also of interest in the video: look at the large cracks in the thicker ice north of Canada.
