Russia has noticed new signs of global disaster


The international group of scientists has found signs of instability of a glacial complex of Vavilov located on Severnaya Zemlya. In recent years the mobility of an ice cap has sharply increased and in 2015 has reached 25 meters a day though in the middle of the last century she didn't exceed several centimeters a day. Article of researchers is published in the Earth and Planetary Science Letters magazine. Was considered that the ice caps located in northern latitudes differ in special stability before global climate change. Though because of increase in average temperature of the atmosphere the glacial cover in the Arctic and Antarctic begins to decrease, scientists didn't expect that it substantially will concern stable integumentary glaciers. New data show that the last were vulnerable to warming, and their thawing can lead to increase in sea level approximately on a third of meter. As scientists consider, about 500 years ago because of rainfall there was a small shift of the western part of a glacial complex towards the sea. When the lower part of a glacier began to thaw, it has accelerated because of reduction of friction force, however at the same time it has begun to thaw even quicker. By 2015 breeds under a complex became very slippery that has considerably accelerated slipping of a glacier. Experts note that in 30 years prior to 2015 a part of a cap has promoted on two kilometers, and the volume of the lost ice was 1,2 cubic kilometers. In 2015-2016 4,5 cubic kilometers of ice have thawed. It is more than important news in Film of Day Telegram-channel. Subscribe!
