Is very popular proposed in the past century the hypothesis of Serbian scientist Milan , which explained climatic changes by the periodic oscillations of the inclination of the rotational axis of planet and distance of the Earth from the sun. The existing at present integumentary glaciers - these are the remainders of the enormous glacial panels, which in the last glacial epochs existed in the temperate latitudes. And although today they not as scale as in the past, nevertheless their sizes impress. One of the significant - Antarctic glacial cover. The maximum power of its ice exceeds 4,5 km, and the area of propagation almost is 1,5 times more than the area of Australia. Ice of many glaciers spreads from several centers of cupola to the different sides. It moves in the form enormous flows with a velocity of 300-800 m per year. Occupying entire Antarctica, the cover in the form of outlet glaciers flows in the sea, giving life to numerous icebergs. The glaciers, which lie or, are more accurate, floating in the region of coastal line, they are called shelf, since they are arranged in the region of the underwater outskirts of continent - shelf. Such ice shelfs exist only in Antarctica. The largest ice shelfs are located in West Antarctica. Among them ice shelf Ross, on whom is located American Antarctic station “McMurdo”.
Another colossal glacial cover is located in Greenland, occupying more than 80% this largest island of peace. To ices of Greenland are fallen about 10% of entire ice on the Earth. The rate of flows of ice here are much less than in Antarctica. But also in Greenland there is its record holder - glacier, which moves at a very high speed - 7 km per year! Reticulated ice formation is characteristic for the polar archipelagoes - Earth Franz Joseph, Spitsbergen, Canadian Arctic archipelago. This type of ice formation is transitional between the integumentary and the mountain. In the plan these glaciers resemble cellular grid, hence and name. From under ice in many places come out as islands in the ocean, the apexes, pointed peaks, cliffs, sections of land.
