An iceberg the size of Manhattan broke away from the floating end of a glacier in Greenland yesterday (16th of July).
The giant iceberg measuring 46 square miles (120 Km2) separated from the terminus of the Petermann Gaclier; as had been predicted by scientists last autumn.
The floating ends of glaciers, known as ice shelves, act as doorstops. When these ice shelves suddenly splinter and weaken or even collapse entirely, as has been observed in Antarctica, the glaciers that feed them speed up, dumping more ice into the ocean and raising global sea levels.
Andreas Muenchow, an associate professor of physical ocean science and engineering at the University of Delaware, said in a statement; “The Greenland ice sheet as a whole is shrinking, melting and reducing in size as the result of globally changing air and ocean temperatures and associated changes in circulation patterns in both the ocean and atmosphere”
