– The scary part of this article is towards the end. And I quote:
‘This study and other GRACE studies published by [others] all agree that there is significant mass wastage of Greenland into the ocean,” notes glaciologist Eric Rignot of NASA’s Jet Propulsion Laboratory. “None of this has been predicted by numerical models, and therefore all projections of the contribution of Greenland to sea level [rise] are way below reality.“‘
– To get an idea of why this is scary, read about the Thermohaline Circulation here and especially here.  This is definitely an evolving piece of the Perfect Storm.

Of late, the enormous glaciers that flow down to the sea from the interior of Greenland have been picking up speed. In the last few years, enough ice has come off the northern landmass to sustain the average flow of the Colorado River for six years or fill Lake Mead three times over or cover the state of Maryland in 10 feet of water, assuming it were perfectly flat. And whether it is the glaciers’ weight, speed or volume that is measured, a quickening of the their movement can be detected. In fact, the latest gravity-based measurements show that the glaciers lost roughly 101 gigatons of ice annually between 2003 and 2005, according to a paper published online in Science.
