Giant Antarctic Ice Shelf Collapses

National Geographic News

New satellite images reveal what scientists call the "runaway" collapse of an enormous ice shelf in Antarctica as the result of global warming.
The chunk of coastal ice was some 160 square miles (415 square kilometers) in area—about seven times the size of Manhattan.
The shelf's rapid collapse began on February 28 (see image sequence at top right), sending a giant swath of broken ice into the sea (detail at bottom).
"[It's] an event we don't get to see very often," Ted Scambos, lead scientist at the U.S. National Snow and Ice Data Center in Boulder, Colorado, said in a press statement.
