#Repost @nasa with @appreposter We've discovered a new mode of ice loss in Greenland. A new NASA study finds that during Greenland's hottest summers on record, 2010 and 2012, the ice in Rink Glacier on the island's west coast didn't just melt faster than usual, it slid through the glacier's interior in a gigantic wave, like a warmed freezer pop sliding out of its plastic casing. The wave persisted for four months, with ice from upstream continuing to move down to replace the missing mass for at least four more months.
Seen here is the Rink Glacier in western Greenland, with a meltwater lake visible center.
