A chunk of ice twice the size of Manhattan has broken off Greenland in the last two years
A 44-square-mile chunk of ice, about twice the size of Manhattan, has broken off the Arctic's largest remaining ice shelf in northeast Greenland in the last two years, leaving scientists fearful over its rapid disintegration.
The territory's ice sheet is the second biggest in the world behind Antarctica's, and its annual melt contributes more than a millimeter rise to sea levels every year.
"We should be very concerned about what appears to be progressive disintegration at the Arctic's largest remaining ice shelf, because upstream ... is the only major Greenland ice sheet ice stream," said Jason Box from The Geological Survey of Denmark and Greenland (GEUS) in a statement on Monday.
"These last two summers have been exceptionally warm," Box said, speaking to CNN Monday.
