Climate fear over iceberg twice size of Manhattan

AN ICEBERG twice the size of Manhattan has broken off a glacier in Greenland, according to NASA satellite imagery, in what could be the latest sign of global warming.

The massive chunk of ice, which measures 46 square miles, broke off the Petermann Glacier on the coast of Greenland, which produced a similar ice island twice as large in 2010.

NASA said the crack in the glacier had been visible since 2001, and that its polar-orbiting Aqua satellite had observed the break on July 16-17. The Canadian and Greenland governments are now watching the iceberg, which could cause a major hazard to shipping.

Scientists believe that when icebergs break off the edge of Greenland it can increase the rate at which glaciers on land melt, pushing up sea levels.

A study in the University of Cambridge found the speed at which glaciers are melting on Greenland has doubled in the last decade. (© Daily Telegraph, London)
