From Antarctica will break away a huge iceberg

От Антарктиды отколется огромный айсбергFrom the last remaining part of the ice shelf Larsen C for some time you break a block of ice with an area of about 5 thousand sq. km.

From the last remaining part of the ice shelf Larsen C for several weeks or months will break away the block of ice with an area of about five thousand square kilometers (it’s like two-thirds of the Chernivtsi region).

Glacier Larsen – the last remaining intact part of the Larsen ice sheet, which previously consisted of three parts and had a total area comparable to the area of the island of Jamaica. In recent decades, the glaciers of the Larsen A and Larsen B collapsed and went under water, as they say many scientists, of global warming.

Larsen A broke off from the main body of the glacier in 1995. In 2002 the same thing happened with a part of the Larsen area of 3250 sq km and a thickness of 220 m.

Only 35 days Larsen collapsed almost completely.

Now the process of disintegration reached the last part of the glacier Larsen.

In December last year, the American space Agency NASA showed pictures of the fault, with a width of 100 m and a depth of 500 m formed on the Larsen C. When this crack reaches the ocean from the glacier will break away the ice floe with an area of 5 thousand square kilometers.

The fault is only 100 m wide, but deeper into it, as scientists assume, reaches half a kilometer

It can happen within months. Now the fault remains the 20 km to the ocean. In December of last year the crack has passed a comparable distance, 18 km, just a few weeks.

“If after a few months she hasn’t broken off, and I would be very surprised,” said Professor Alan Luckman, head of the Midas project, in which scientists are monitoring the melting of the polar ice.

Team Luckman did not consider the destruction of the glacier as a direct result of global warming. As scholars have noted, a rift in the Larsen With existed for decades. However, to rise sharply it began in recent years.

Scientists worry that the separation of the ice will affect the rest of the glacier.

“We are confident, although many others do not agree that the remaining glacier will be less stable than it is now,” said Professor Luckman.

The ice, which will break away from the Larsen C, is one of the largest icebergs in history, but her dip in the sea significantly affect the level of the world oceans. According to some estimates, if the water will leave the whole glacier “Larsen C” entirely, sea level could rise by 10 centimeters.
