Washington (AP) A chunk of Antarctic ice nine times the size of Manhattan has suddenly collapsed, putting an even larger glacial area at risk.

Satellite images show the runaway disintegration of a 220-square-mile chunk in western Antarctica. British scientist David Vaughan says it's the result of global warming.

The rest of the Connecticut-sized ice shelf is holding on by a narrow beam of thin ice and scientists worry that it too may collapse. Larger, more dramatic ice collapses occurred in 2002 and 1995.
