Blocks of Ice Shelf in Antarctica "just tumbling and crumbling into the ocean"

Directly attributed to warming according to Reuters:

Satellite images show that a large hunk of Antarctica's Wilkins Ice Shelf has started to collapse in a fast-warming region of the continent, scientists said on Tuesday.

The area of collapse measured about 160 square miles of the Wilkins Ice Shelf, according to satellite imagery from the University of Colorado's National Snow and Ice Data Center.

The Wilkins Ice Shelf is a broad sheet of permanent floating ice that spans about 5,000 square miles (13,000 square km) and is located on the southwest Antarctic Peninsula about 1,000 miles south of South America.

"Block after block of ice is just tumbling and crumbling into the ocean," Ted Scambos, lead scientist at the National Snow and Ice Data Center, said in a telephone interview.

The failure to address global warming is another legacy of George Bush and Dick Cheney -- something of which their children and grandchildren will be very proud.
