General forecast of the evolution of the coastal zone of the Eurasian Arctic seas in the 21st century

Principal regularities of the evolution of the Arctic coasts of Eurasia in the 21st century related to the climate warming and sea level rise are assessed. It is stated that the most significant changes may be expected in the most ice-covered seas of the Arctic Ocean, where the area of the ice cover may significantly decrease while the duration of the ice-free periods will grow. Thermoabrasive coasts will be the most subjected to the changes; the rate of their recession will increase 1.5–2.5 fold. The further development of accumulative coasts in the Arctic seas will proceed against the background of a transgression; meanwhile, in the 21st century, one can expect no catastrophic changes such as washing away of coastal accumulative features.
