Melting of Greenland has reached frightening levels


Greenland-akujt

Previously pahasur melting ice in Greenland during this month has baffled NASA scientists and has raised concerns that the region is losing a very large part of ice, much more than was anticipated.
According to NASA spokesman about half of the ice surface Greennland-es dissolves in the usual way during an average summer.
But independent data from satellites during July, analizara by NASA experts and scientists have shown that in less than a week the amount of ice melt has gone from 40% to 97%.
In shumne than 30 years of observations, satellites have never measured this amount of melting, which reaches almost the entire surface of the Greenland ice coverage-es.
When Son Nghiem of the Jet Propulsion Laboratory of NASA observed the phenomenon of melting, he said in the press release NASA: "This is so awesome At the beginning I put in doubt the data; Was it real or was everything due to an error in the data that we had? "

Scientists to Goddard Space Flight Center NASA, the University of Georgia-Athens and the City University of New York, all have confirmed the thawing process.
Manager kriptosferes programs that NASA, Tom Wagner gave merit observation satellites melting and explained to The Huffington Post that, although specific event may be part of a natural change, "We have sufficient evidence that Greenland -a is losing ice, perhaps due to global warming, and this is contributing significantly to increasing the level of the sea. "

Wagner said that ice is being diluted significantly around the peripheral side, thus changing the overall mass of the ice Greenland-es, and he believes that this is largely due to warming ocean waters.

He said carefully: "There is likely to be related to anthropogenic warming."
This extreme sapecifike fusion occurred in part because of an unusual weather over Greenland this year.
Distinct fusion occurred in specific regions of Greenland as for example the area around Summit Station, located two miles above sea level. Never since 1889 has not been such a merger, according to the analysis of ice crust tepershkruar press release NASA.
Researcher ice Lora Koenig said that similar fusion event occurring once in about 150 years. But she added that if we will be confronted with such events again in the next few years, will have to fillpnim seriously worried.

"One of the big questions is: 'What has happened to the Arctic in general?'." Wagner said Huff Post.
Only last week a another unusual event occurred in the region; Petermann Glacier Greenland-es broke an iceberg the size of Manhattan twice.

In recent months, separated from each other studies have been done showing that people are playing a crucial role in heating oqesaneve and that specific regions of the world are more susceptible to the rise of sea level.
Wagner explained that in recent years, studies have observed a dilution of sea ice and general changes dramatically.
It was clear: "We must always have in mind the fact that Greenland is losing a tremendous amount of ice and that this will affect the entire planet.
