4,500-year-old ice shelf breaks away

http://www.cnn.com/2008/TECH/scie...03/arctic.ice.shelf.ap/index.html

Excerpt:

Martin Jeffries of the U.S. National Science Foundation and University of Alaska Fairbanks said in a statement Tuesday that the summer's ice shelf loss is equivalent to over three times the area of Manhattan, totaling 82 square miles -- losses that have reduced Arctic Ocean ice cover to its second-biggest retreat since satellite measurements began 30 years ago.

"These changes are irreversible under the present climate and indicate that the environmental conditions that have kept these ice shelves in balance for thousands of years are no longer present," said Muller.

During the last century, when ice shelves would break off, thick sea ice would eventually reform in their place.

"But today, warmer temperatures and a changing climate means there's no hope for regrowth. A scary scenario," said Muller.

Thanks, Paul. How quickly and thoughtlessly we destroy that which cannot be replaced.
