An ice island four times the size of Manhattan broke off from one of Greenland’s two main glaciers.
They’re calling it the biggest event in the arctic in nearly 50 years.
The new ice island broke off on Thursday about 620 miles south of the North Pole.
The ice island has an area of 100 square miles and a thickness up to half the height of the Empire State Building.
Scientists have said the first six months of 2010 have been the hottest globally on record.
Thousands of icebergs calve off Greenland’s glaciers annually, but they are seldom so large.
The last time such a large ice island formed was in 1962.
