Posted Mon Feb 15 2010: from New Scientist: Greenland's glaciers disappearing from the bottom up http://apocadocs.com/s.pl?1266193426 Water warmed by climate change is taking giant bites out of the underbellies of Greenland's glaciers. As much as 75 per cent of the ice lost by the glaciers is melted by ocean warmth. "There's an entrenched view in the public community that glaciers only lose ice when icebergs calve off," says Eric Rignot at the University of California, Irvine. "Our study shows that what's happening beneath the water is just as important."... The underwater faces of the different glaciers retreated by between 0.7 and 3.9 metres each day, representing 20 times more ice than melts off the top of the glacier. This creates ice overhangs that crumble into the sea, says Paul Holland at the British Antarctic Society.
