Antarctica melts: scientists told about the appearance of thousands of lakes of melt water – Moskovsky Komsomolets

If the water of these lakes seeps under a glacier, it will last a short time

Today, at 18:04, Visits: 1990

On the glacier Langhovde in East Antarctica c 2000 to 2013 there was almost 8 thousand blue lakes with melt water, like that earlier this territory did not occur. British experts from Durham University, studied this phenomenon, expressed concern that the complete disappearance of the glacier – a matter of time

Experts studied more than one and a half hundreds of satellite images and analyzed other data previously collected on the 7990 blue lakes, and then came to the conclusion that they were formed under the influence of warm air. It is not excluded that meltwater, located in some of these lakes can seep under the glacier, significantly accelerating its melting and making it irreversible.

Similar in effect, but even more large-scale events for today observed in Greenland, where, inter alia, for this reason, from 2011 to 2014 more than one trillion tons of melted ice. It is possible that in the future something like waiting and glacier Langhovde, the researchers note, have published their work in the scientific Geophysical Research Letters.

In May this year the attention of specialists attracted other Antarctic glacier, called Totten, who, It appeared gradually destroyed warm salt water. The researchers expressed concern that the melting of the glacier could potentially lead to an increase in global sea level by more than two meters (although it is, in all probability, will take at least several centuries).

Although the scientists from time to time report on the melting of individual glaciers on the Antarctic, in general, it considered the ice pretty well protected from melting due to climate change. One explanation for this was recently discovered in the so-called Southern Ocean at a depth of more than three kilometers of water, do not participate in the circulation and remains one of the most “virgin” of global warming in the world.
