Greenland's ice 'melts in spurts'

Ice loss from Greenland's vast sheet may happen mainly in short bursts, research by Danish scientists suggests. They used aerial photos dating back to the 1980s to plot shrinking of glaciers around the island's northwest coast. In the journal Science, they show that most of the ice loss happened in two periods - 1985-1993 and 2005-10 - with relative stability in between. See full Article.
