A chunk of Antarctic ice about seven times the size of Manhattan has suddenly collapsed, putting an even greater portion of glacial ice at risk, scientists said.
Satellite images show the runaway disintegration of a 415 square kilometre chunk in western Antarctica, which started on February 28. It was the edge of the Wilkins ice shelf and has been there for hundreds, maybe 1,500 years. http://au.news.yahoo.com/080325/2/169d4.html?f=mv
This is the result of global warming, said British Antarctic Survey scientist David Vaughan.
