The long-term data series of the ice coverage condition of the Arctic sea during the whole period of observations (from 1935–1940 to 2014) have been analyzed. It has been shown that the last decade is characterized by a sharp drop in the ice cover area in all seas. The data provided by the ocean meteorological stations confirm the increase in air temperatures over the same period. This is accompanied by a significant increase in the rate of coastal retreat and the rates of thermal denudation of icy coasts. The ratio of the rates of thermal denudation and thermal abrasion on the eroded ice complex has been estimated.
