Polar ice is melting ever faster:

Antarctica, Greenland ice definitely melting into sea, and speeding up, experts warn

What had been a blurry picture about polar ice — especially how it impacts sea levels — just got a whole lot clearer as experts on Thursday published a peer-reviewed study they say puts to rest the debate over whether the poles added to, or subtracted from, sea level rise over the last two decades.

Combining satellite data from dozens of earlier studies, the study "shows that the Antarctic and Greenland ice sheets have contributed just over 11 millimeters (0.4 inches) to global sea levels since 1992," he added. Two-thirds was from Greenland, a third from Antarctica.

Published in the journal Science, the study was based on input from 47 experts at the 26 institutes that produced earlier studies with wild variations. Some estimated melt was raising sea levels by up to 2 millimeters a year, Shepherd noted, while a few said that overall polar ice was growing, and thus countering sea level rise.

Even more dramatic, Ivins said, is that Greenland "is losing mass at about five times the rate today as it was in the early 1990s."
Greenland's melt rate has gone from 55 billion tons a year in the 1990s to nearly 290 billion tons a year recently, according to the study.
