Arctic summers may be ice-free by 2013.

In one of the most “dramatic forecasts yet for the disappearance of Arctic sea ice,” Professor Wieslaw Maslowski told an American Geophysical Union meeting that the “latest modelling studies indicate northern polar waters could be ice-free in summers within just 5-6 years. … Summer melting this year reduced the ice cover to 4.13 million sq km, the smallest ever extent in modern times.”
