Satellite captures thinning ice shelf

A European satellite has observed a rapid retreat of one of Antarctica's ice shelves, which is half the size it was 10 years ago, the European Space Agency. The Larsen Ice Shelf, which lies on a peninsula south of Chile, has decreased from 3,463 square kilometers (1,337 square miles) in March 2002 to 1,670 square kilometers (645 square miles) today, a change the European Space Agency blames on warmer temperatures.

  1. Envisat radar image of the Larsen Ice Shelf acquired on March 19, 2012. Antarctica

  2. This image provided by NASA shows a photo acquired March 16, 2011 of the Sulzberger Ice Shelf showing the iceberg calving event associated with the Japan earthquake and resulting tsunami that occurred on March 11, 2011. An earthquake off the coast of Japan caused massive waves to explode out from its epicenter. Swells of water swarmed toward an ice shelf in Antarctica, 8,000 miles (13,600 km) away, and about 18 hours after the earthquake occurred, those waves broke off several chunks of ice that together equaled about two times the surface area of Manhattan. According to historical records, this particular piece of ice hadn't budged in at least 46 years before the tsunami came along. (AP Photo/European Space Agency via NASA)

  4. In this July 27, 2008 file photo, a chunk of ice is shown drifting after it separated from the Ward Hunt Ice Shelf off the north coast of Ellesmere Island in Canada's far north. This past summer, Ward Hunt Ice Shelf's central area disintegrated into drifting ice masses, leaving two separate ice shelves measuring 87.65 and 28.75 square miles (227 and 74 square kilometers) respectively, reduced from 131.7 square miles (340 square kilometers) the previous year.
