VIDEO: Giant Iceberg Breaks Off Greenland Glacier

Science & Space

An ice chunk twice the size of Manhattan broke off of Greenland last week, in another sign of Arctic warming.

The 46-square-mile piece of the Petermann Glacier in Greenland “calved” away from the mainland on Monday. It tore along a crack in the glacier that researchers have been watching for years.

Another iceberg twice its size (i.e., four times the size of Manhattan) broke off the same glacier in 2010.

This striking video by New Scientist shows the damage Petermann has sustained over the past few years. A time-lapse gives a dramatic display of the earliest loss from the glacier (beginning in 2009).
