    WILKINS ICE SHELF, Antarctica (Reuters) - A huge Antarctic ice shelf is on the brink of collapse with just a sliver of ice holding it in place, the latest victim of global warming that is altering maps of the frozen continent.

    "We've come to the Wilkins Ice Shelf to see its final death throes," David Vaughan, a glaciologist at the British Antarctic Survey (BAS), told Reuters after the first -- and probably last -- plane landed near the narrowest part of the ice.

    The flat-topped shelf has an area of thousands of square kilometers, jutting 20 meters (65 ft) out of the sea off the Antarctic Peninsula.

    But it is held together only by an ever-thinning 40-km (25-mile) strip of ice that has eroded to an hour-glass shape just 500 meters wide at its narrowest.

    In 1950, the strip was almost 100 km wide.

    The ocean is warming so the ice shelfs in Antarctica are shrinking, but the hole in the ozone we created is causing parts of Anarctica to cool.

    It's weird.

    Antarctic ice melting from below, finds study
    June 13, 2013 > Ice loss in Antarctica is largely driven by warm ocean currents, a discovery that could lead to more accurate predictions of sea level rise.

    1,000 sq km lol. This is one/forth the size of road island!
    The square kilometers of Rhode Island is(4,002 km square)

    About 7 times the land area of Portland Oregon. Wake me when the entire Antarctic east ice sheet is sliding into the Antarctic ocean. Ok?
