Giant Antarctic Ice Shelf Collapses

The National Ice and Snow Institute (NISDC) has released a report documenting a dramatic and troubling collapse of a large portion (nine times the size of Manhattan) of the Wilkins Ice Shelf in Antarctica.

Satellite imagery from the National Snow and Ice Data Center at the University of Colorado at Boulder reveals that a 13,680 square kilometer (5,282 square mile) ice shelf has begun to collapse because of rapid climate change in a fast-warming region of Antarctica.

The Wilkins Ice Shelf is a broad plate of permanent floating ice on the southwest Antarctic Peninsula, about 1,000 miles south of South America. In the past 50 years, the western Antarctic Peninsula has experienced the biggest temperature increase on Earth, rising by 0.5 degree Celsius (0.9 degree Fahrenheit) per decade. NSIDC Lead Scientist Ted Scambos, who first spotted the disintegration in March, said, “We believe the Wilkins has been in place for at least a few hundred years. But warm air and exposure to ocean waves are causing a break-up.”

The ice shelf began its visible collapse on February 28th, when a huge iceberg (41 x 2.5 kilometers – 25.5 by 1.5 miles) broke away, triggering a wider collapse of 405 square kilometers (160 square miles) of the shelf…

  1. And that’s just the part that’s already collapsed.  The rest of it is ~equivalent to Connecticut…

    Rather than poo-flings about “Clintonstein”.  God, has this site sunk to the orange level?  

    Thank you for this, well, awful news.  

    Mu . . .

  2. speechless.

  3. There’s probably plenty of oil in Antartica and we’ll be able to get to it….

    Grrrrrrrrr…..

  4. HAARP, the high altitude aroaral research project is a household word in American.

    When the inscription of the Georgia Guidestones complete with plausible explanations of it’s intent are as commonly known as the Ten Comandments.

    When the oceans rise and wipe out the cell phone manuafacturing base in south east asia.

    Then I might entertain the idea of a tax to establish a global government, not one second before.

    ie, ‘reading’ news about this every day.  didn’t this happen something like 15 years before predicted?  according to one scientist quoted somewhere.
