Climate Change in Eurasian Arctic Shelf Seas

This book analyzes the latest research on ice cover variability in the Arctic seas during the 20th and early 21st centuries. It includes a discussion of the Arctic climate system and the impact of climate change from internal and external factors.

In this book the eminent authors analyse the ice cover variability in the Arctic Seas during the 20 th and early 21 st centuries. In the first two chapters, they show that multi-year changes of the sea-ice extent in the Arctic Seas were formed by linear trends and long-term (climatic) cycles lasting about 10, 20 and 60 years. The structure of temporal variability of the western region (Greenland Kara) differs significantly from the eastern region seas (Laptev and Chukchi). In the latter region, unlike the former area, relatively short-period cycles (up to 10 years) predominate. The linear trends can be related to a super-secular cycle of climatic changes over about 200 years. The most significant of these cycles, lasting 60 years, is most pronounced in the western region seas.

Summarizes research results of centennial changes of sea ice cover of the Arctic seas of the Eurasian shelf Uniquely analyses ice and hydrometeorological characteristics over 80-100 years in the 20th century Examines spatial and temporal special features of the constituents of the Arctic climate system Discusses in detail the different parameters of the Arctic climate system. Proves the importance of natural climatic changes induced by internal and external causes
