New signs of global disaster are found


Climatologists have for the first time registered disappearance of long-term ice to the north from Greenland. According to scientists, it can threaten survival of the Arctic seals and polar bears. The Science Alert edition reports about it. The data obtained by satellites show that the ice covering a part of the Arctic for a long time became fragile and more mobile. At the beginning of August it has been carried by wind from the northern coast of Greenland, having opened the surface of the sea which has been covered by him earlier. Such mobility is caused by change of thickness of an ice cover, and at the moment almost all ice in the Arctic is one-year and, therefore, to thinner. Earlier scientists considered that in this region long-term ice will remain for a long time. Usually its thickness reaches more than four meters, and in places — 20 meters. Thinning is 40 percent lower than an average, according to researchers, is connected with unusually warm beginning of year also August. It threatens habitats of polar bears who use an ice cover for hunting for seals. It is more than important news in Film of Day Telegram-channel. Subscribe!
