    CNN) -- A large ice shelf is "imminently" close to breaking away from part of the Antarctic Peninsula, scientists said Friday.

    Scientists are investigating whether the ice breakup is caused by global climate change.

    Satellite images released by the European Space Agency on Friday show new cracks in the Wilkins Ice Shelf where it connects to Charcot Island, a piece of land considered part of the peninsula.

    The cracks are quickly expanding, the ESA said.

    Scientists are investigating the causes for the breakups and whether it is linked to global climate change.

    The Wilkins Ice Shelf -- a large mass of floating ice -- would still be connected to Latady Island, which is also part of the peninsula, and Alexander Island, which is not, said professor David Vaughan, a glaciologist at the British Antarctic Survey.

    The ice shelf experienced a great amount of changes last year, the ESA said.

    In February 2008, the shelf dropped 164 square miles (425 square kilometers) of ice. In May it lost a 62-square-mile chunk.

    That meant the "bridge" of ice connecting Wilkins to the islands was just 984 yards wide at its narrowest location, the ESA said.

    Further rifts developed in October and November, said Angelika Humbert of the Institute of Geophysics at Germany's Muenster University.

    "During the last year the ice shelf has lost about 1800 square kilometers (694 square miles), or about 14 percent of its size," Humbert said.

    Antarctica's ice sheet was formed over thousands of years by accumulated and compacted snow. Along the coast, the ice gradually floats on the sea, forming massive ledges known as ice shelves, the ESA says.

    Several of these ice shelves, including seven in the past 20 years, have retreated and disintegrated.

    Ah yes, the old Wilkins gruffle n shuffle story is back yet again!

    And just in time for the impending cap n trade debate coming up in Congress - imagine that!

    We should all make peace with our Maker folks - .39% of the current ice sheet is showing signs of jumping off! And pay no mind to the other thousands of acres of increasing ice sheets in the far more vast (and cooling) areas of the Antarctic. No - we must concentrate on this particular example because those falling sheets of ice make for great entertainment and the perfect PR tool for the global warming industry!

    Yes indeed, that's .39% of the Antarctic ice sheet showing some strain.

    How could we not get in a complete tissy about that??????

    Some of us like the idea of global warming.

    I seriously don't like cold weather or cold water.

    I'm a surfer, and with warmer water comes more comfort and larger storms, generating better surfing conditions.

    The consequences of global warming are not a big deal. The planet itself doesn't care. It'll hold up just fine with or without us.


    Global warming is an issue about people, not temperature.

    Yes, the deniers are pulling a scam for the oil and coal companies.

    Many of the deniers were funded by the American Petroleum Institute.
