Abstract : Empirical data are examined which characterize the role of the polar regions in the global carbon cycle, and the role of polar oceans as atmospheric carbon sinks is discussed. The dependence of the annual variation of atmospheric C02 content on latitude is analyzed. Natural and anthropogenic sources of C02 are studied, as well as their manifestation in polar regions. The results of carbon cycle numerical modeling with linear and non-linear box models for different scenarios of anthropogenic C02 growth are presented. The role of oceanic, biospheric and anthropogenic sources in carbon cycle dynamics is analyzed. The results of modeling the climate and its changes are discussed for different scenarios of energetics development with models of different complexity. Possible causes of climate warming and cooling are considered for the polar regions.
