Massive ice shelf collapsing off Antarctica



Scientists are citing "rapid climate change in a fast-warming region of Antarctica" as the cause of an initial collapse of the Wilkins Ice Shelf. The damage got started at the end of February when an iceberg dropped off and triggered the "runaway disintegration" of a 160-square-mile portion of the 5,282-square-mile shelf.

The ice shelf, which scientists speculate has floated in the Antarctic region for hundreds of years, is succumbing to recent rises in temperature in the area--an average of 0.9 degree Fahrenheit every 10 years for the last 50 years.

This series of pictures that show the beginning of the breakup were taken by NASA's Moderate Resolution Imaging Spectroradiometer sensor, which flies on its Earth Observing System Aqua and Terra satellites.
