U.S. scientists say an iceberg twice the size of the isle of Manhattan, or about 120 square kilometers, has broken off from a glacier in northern Greenland in what could be the latest sign of climate change.
Scientists say NASA satellites this week captured images showing the gigantic chunk of iceberg pulling free from the main body of the Petermann Glacier.
It was the second time since 2010 that a large piece of the Petermann Glacier has broken off.
The iceberg that fell from the glacier in 2010 was twice the size of the piece that broke off this week.
Researchers believe global warming is responsible for pieces breaking off the glacier, but they have no conclusive proof to support the theory.
