Iceberg breaks off from Greenland’s Petermann Glacier

An iceberg twice the size of Manhattan has broken away from the Petermann Glacier in northern Greenland. Images from a Nasa satellite show the island breaking off a tongue of ice that extends at the end of the glacier.

In 2010 an ice island measuring 250 square km (100 square miles) broke off the same glacier. The process that spawns icebergs – known as calving – is a natural, periodic process affecting all glaciers that terminate at the ocean.

A previous calving event at the same glacier in 2010 created an iceberg twice the size of this one.

Scientists have raised concerns in recent years about the Greenland ice shelf, saying that it is thinning extensively amid warm temperatures.


The calving is not expected have an impact on sea levels as the ice was already floating.
