    More than two and a half square miles of a Greenland glacier broke up on July 6 and 7, moving the edge of the glacier a mile inland in one day, the furthest inland it has ever been observed. While such calving of glaciers isn't rare, seeing it happen at high resolution by satellite in almost real time is.

    NASA-funded researchers have been monitoring Greenland's Jakobshavn Isbrae using satellite images from the Landsat, Terra, Aqua and DigitalGlobe's WorldView 2 satellites. The breakup was detected hours after it happened by Ian Howat of the Byrd Polar Research Center at Ohio State University and Paul Morin, director of the Antarctic Geospatial Information Center at the University of Minnesota.

    "This event is unusual because it occurs on the heels of a warm winter that saw no sea ice form in the surrounding bay," Thomas Wagner, cryospheric program scientist at NASA Headquarters, said in a release. "While the exact relationship between these events is being determined, it lends credence to the theory that warming of the oceans is responsible for the ice loss observed throughout Greenland and Antarctica."

    Jakobshavn Isbrae is located on the west coast of Greenland. It has retreated more than 27 miles since 1850, six of them in the last decade. Jakobshavn is also believed to be the single largest contributor to sea level rise in the northern hemisphere.

    Not all we need to know. Also important to recognize our tax dollars at work "seeing it happen at high resolution by satellite in almost real time is."

    (CNN) -- A piece of ice four times the size of Manhattan island has broken away from an ice shelf in Greenland, according to scientists in the U.S.

    The 260 square-kilometer (100 square miles) ice island separated from the Petermann Glacier in northern Greenland early on Thursday, researchers based at the University of Delaware said.

    The ice island, which is about half the height of the Empire State Building, is the biggest piece of ice to break away from the Arctic icecap since 1962 and amounts to a quarter of the Petermann 70-kilometer floating ice shelf, according to research leader Andreas Muenchow.

    Holy crap! We've been polluting the ever loving crap out of the planet and it took us 48 YEARS to break off a bigger chunk! That does it! I'm going to pollute MORE!

    You fcukking k00k......................:lol:

    This is what you get when you got people with nothing meaningful going on in their lives. Its quite that simple. Their life hinges on the next environmental change so that the k00k can blow it up into something hysterical!!! This nuts eye's lit up when he saw this story............100% certainty. Because then he can come on here and matter in life for a few hours!!! The kind of loser nobody wants at their party. A modern day hermit with a PC.
