Sliding Scale
It's Getting Hot in Herre

Wow. It's been hot around the US lately. I wonder if that has anything to do with global warming? Probably not. Anyhoo, here's some news out of Greenland about the escalation in melting of a glacier there (via The Independent):

 
Scientists monitoring a glacier in Greenland have found it is moving into the sea three times faster than a decade ago.

Satellite measurements of the Kangerdlugssuaq glacier show that, as well as moving more rapidly, the glacier's boundary is shrinking dramatically - probably because of melting brought about by climate change.

The Kangerdlugssuaq glacier on Greenland's east coast is one of several that drains the huge Greenland ice sheet. The glacier's movements are considered critical in understanding the rate at which the ice sheet is melting.
[...]
If the entire Greenland ice sheet were to melt into the ocean it would raise sea levels by up to seven metres (23ft), inundating vast areas of low-lying land, including London and much of eastern England.

Computer models suggest that this would take at least 1,000 years but even a sea-level rise of a metre would have a catastrophic impact on coastal plains where more than two-thirds of the world's population live.

Measurements taken in 1988 and in 1996 show the glacier was moving at a rate of between 3.1 and 3.7 miles per year. The latest measurements taken this summer show it is now moving at 8.7 miles a year.
