Greenland Ice Melt Speeds Up

SFGate:

Greenland Ice Melt Speeds Up – NASA scientists reading signals from a satellite in orbit, and flying aboard a low-flying plane over Greenland, are finding fresh evidence of melting snows and thinning glaciers in vast areas of the massive island.

Their observations confirm the climate’s warming trend in the far northern reaches of the world, they say, where changes in the circulation of waters feeding into the Arctic Ocean are altering crucial patterns of ocean currents there with effects that are increasingly uncertain.

The pace of glaciers sliding into the sea along Greenland’s southwestern coast “is speeding like gangbusters this year,” said William Krabill, leader of a NASA team that has just ended a three-week airborne mission probing glacier dynamics with lasers and radar.
