News > Giant iceberg breaks off Greenland glacier
An ice island with an area of 260 square km has broken off from one of Greenland's two main glaciers, in an event that is the biggest of its kind for nearly 50 years. The Petermann Glacier has just split in two - sending a 100 sq mile iceberg floating off into the Arctic Ocean. The ‘ice island’ which is as big as 48,000 football pitches, is the largest iceberg seen for 48 years. It is so large that there are fears that it could cause chaos to shipping if it drifts further south. A Canadian researcher looking at satellite images this week spotted the giant iceberg. A chunk of ice had been predicted to come away from the Petermann Glacier - one of the two largest remaining ones in Greenland - but never at this scale. The iceberg is said to contain enough water to supply the USA for four months.
