As an answer to the remark of A.V. Smagin about the disbalance of the carbon cycle for ecosystems on the territory of Russia and the possible reasons of this phenomenon revision of carbon balance based on published data was conducted. The incoming flux - the net ecosystem exchange - estimated by various authors is about 0.45 GtC/year. This value is in a good agreement with estimates of carbon uptake by terrestrial ecosystems of the northern hemisphere done by inverse modeling. As outcoming fluxes carbon sinks through the rivers (70-76 MtC/year), net methane flux to the atmosphere (16 MtC/year), carbon sequestration in the form of peat in wetlands (50 MtC/year) and in the form of humus in soils (110 MtC/year), as well as deposits formed during fires in natural ecosystems (120 MtC/year) are considered. The difference between incoming and outcoming fluxes is about 80 MtC/year, and according to the literature data it is possible to accept this value as a biomass growth of natural ecosystems on the territory of Russia.
