Two of Greenland’s largest glaciers lost more ice to global warming over the last month, US researchers said today. Glaciologists at the Byrd Polar Research Centre at Ohio State University observed the break-ups by monitoring daily NASA satellites images as well as time-lapse photography from cameras monitoring Greenland’s glaciers. A huge chunk of the Petermann Glacier measuring 29 square kilometres - roughly half the size of Manhattan - broke away between July 10 and 24, said Jason Box, a professor of geography at Ohio State University. Petermann, in northern Greenland, last lost a major mass of ice - 86 square kilometres - between 2000 and 2001.
