Greenland glacier sheds huge iceberg

Satellite images, recorded by NASA, showed the huge piece of ice, which had broken off the Petermann Glacier on the northwestern coast of Greenland, Reuters reported on Wednesday.

It is the second time in less than two years that a huge piece of ice has broken free from the glacier. In 2010, a similar ice island, twice as large, was chopped off the glacier.

NASA said the rift in the glacier was spotted in 2001, and that its polar-orbiting Aqua satellite, which passes over the North Pole several times a day, had observed the break on July 16-17.

The recent incidents of iceberg calving have raised concerns among scientists who have warned that Greenland ice shelf is thinning extensively amid rising global temperatures.

“We have data for 150 years and we see changes that we have not seen before,” said Oceanographer Andreas Muenchow of the University of Delaware.

Poul Christoffersen of the University of Cambridge Scott Polar Institute, also expressed concerns about the rate at which the glaciers on Greenland were melting, saying the ice on Greenland has been melting faster for the last 20 years because of global warming.

The latest calving is not expected to cause a rise in sea levels as the ice was already floating.
