NASA showed that a large part of the multiannual Arctic ice had disappeared and replaced by thin ice melting in the warmer months. This is reported by Telekritika.info with reference to Aspects
Perennial ice persists for more than two years, it is thicker than the ice age of the season and kills in the sea. It also contains less salt and less likely to melt. The seasonal sea ice thickness reaches about two meters and disappears almost in summer.
It is estimated that the thickness of ice cover since 1
958 has decreased threefold, while the area of perennial ice has decreased by two million square kilometers. According to researchers, in the future, its speed will be significantly reduced, but it will happen because the thick ice completely disappears, but not because of climate change. On the contrary, the arctic will be more exposed to an increase in the average temperature of water and air, which will adversely affect natural ecosystems.
Earlier on September 21, it was reported that an international group of scientists have found signs of instability of the glacial complex Vavilov, located in the north. The mobility of crews has increased dramatically and reached 25 meters per day in 2015, while in the middle of last century it did not exceed a few centimeters per day. “/>
