ScienceDaily reports that an unusually hot melting-season in 2010 accelerated ice loss in southern Greenland by 100 billion tons. Fifty GPS stations planted along the coast to measure the bedrock's natural response to the ever-diminishing weight of ice above it, showed that large portions of the island's bedrock responded by rising another 6mm (0.25 of an inch).
The bedrock rises 15mm a year, but the temperature spike in 2010 lifted it more in only five months--as much as 20mm in some places (0.79 of an inch).
