"Big question for the warm sceanario - Is this a few percent or 0.3 sigma warm, or a whole standard deviation warm ?"

Around the world, ice sheets and glaciers are melting at a rate unprecedented since record-keeping began. Changes in the area and volume of the two polar ice sheets in Antarctica and Greenland are intricately linked to changes in global climate and could result in sea-level changes that would severely affect the densely populated coastal regions on Earth.
Glaciers along the southeastern coast of Greenland are thinning by more than 3 feet a year -- possibly because of global warming, according to a new study by NASA scientists.
Researchers compared aerial surveys of the Greenland ice sheet taken in 1993 and 1994 with a similar survey taken last year. Their data indicated that parts of the ice sheet near the ocean thinned at a rate of more than 3 feet (1 meter) per year.
"Why (glaciers) are behaving like this is a mystery," said Bill Krabill, a researcher at NASA's Goddard Space Flight Center. "But it may indicate that the coastal margins of ice sheets are capable of responding quite rapidly to external changes, such as a warming climate."
Krabill said if the higher rate of ice flowing into the ocean from Greenland "accelerates or becomes more widespread, it would begin to have a detectable impact on sea level."
