Daily satellite images of Greenland's glaciers reveal the break-up of two of its largest glaciers in the last month. A massive 11-square-mile piece broke off the Petermann Glacier in northern Greenland between July 10th and by July 24th. That's half the size of Manhattan. Between 2000 and 2001 the same glacier lost 33 square miles of floating ice.
What worries researchers from the Byrd Polar Research Center at Ohio State University is what appears to be a massive crack further upstream. A break-up there would doom 60 square miles, or one-third of what's left of the massive ice field.

Petermann has a 500-square-mile floating section, the longest floating glacier in the Northern Hemisphere. Photo courtesy Byrd Polar Research Center, Ohio State University.
