Antarctic ice shelf is to disappear by 2020

Antarctic ice shelf is to disappear by 2020

New NASA study revealed that one of the last remaining sections of Antarctica’s Larsen B Ice Shelf is going to disintegrate completely by the end of this decade due to be dramatically weakened.

New NASA study revealed that one of the last remaining sections of Antarctica’s Larsen B Ice Shelf is going to disintegrate completely by the end of this decade due to be dramatically weakened. 

If 10,ooo-year-old ice shelf that is functioning as a barrier disappears, the global sea level will immediately rise and commit global damages of our planet as a consequence.

The evidence of  the ice shelf flowing faster and becoming more fragmented was found by a team led by Ala Khazendar of NASA’s Jet Propulsion Laboratory in Pasadena, California. They investigated that the flow is creating large cracks in the ice shelf and observed warning signs that the ice capt’s remnant is disintegrating. The fact of further ice shelves falling apart became obvious after it partially collapsed in 2002. No one had ever witnessed a large ice mass disappearing so quickly, almost in 6 weeks ice shelf splintered and rapidly vanished, what seemed to have been caused by a series of warm summers on the Antarctic Peninsula, which happen during what in the Northern Hemisphere are winter months.

In January 1995 Larsen B measured 4,445 square miles. Then in February 2002 major disintegration caused it’s falling down to 2,573 square miles. Later during a month it went down to 1,337 square miles.

At the moment the remnant of Larsen B is about 618 square miles what is less than half the size of Rhode Island, the smallest US state.

Other prominent ice shelves in the region also have been affected over the years. Larsen A disintegrated in January 1995. Larsen C remains somewhat stable with some evidence of thinning and melting, what was stated by the European Space Agency after the observation of ice shelves via satellite images in 2012.
