Melting Of Greenland Ice Sheet Accelerates To 3X Rate Estimated In 2001
SYDNEY, 10 August 2006: The Greenland ice sheet is now melting three times faster than predicted, making the likely rise in sea levels this century larger than originally feared, according to a U.S. study published today.

In a study published in the online issue of the U.S. journal, Science, Jianli Chen and colleagues at the University of Texas in Austin have calculated that the Greenland ice sheet has been melting at an accelerated rate since 2004. "A direct consequence of the significant melting would be the global sea level rise," said Chen. "This melting alone will contribute about 0.6 millimetres a year of the global sea level rise. "If the Greenland cap melted completely, it would raise global mean sea level by about 6.5 metres. If this was to occur, most of the world's coastal regions would be subject to flooding," the authors wrote.

Previously Jonathan Gregory, a climatologist at Britain's University of Reading, and Philippe Huybrechts, a glaciologist at the Free University in Brussels, Belgium, had warned in a 1999 study of the possible meltdown of the Greenland ice sheet. It appears these concerns were not unfounded.

Chen and his colleagues used data collected by a pair of satellites known as the Gravity Recovery and Climate Experiment (GRACE) to accurately measure gravity changes as a function of time. They analysed data collected on the gravity variation over Greenland, and then compared the monthly data of the ice sheet between April 2002 and November 2005 for the study.

2. Ahhh, don't be alarmed...this is just part of a natural cycle...
The sock-puppet said so...really!

See, here's proof...

"Say 'It's all part of a natural cycle...!'"

"It's all part of a natural cycle!"

Set the sea level rise you want to see and watch the coastline flood.
