Modern Climate Changes of Biosphere Productivity in Russia and Adjacent Countries

The tendencies in the response of the annual plant productivity and soil organic carbon content in Russia and adjacent countries to climate changes, observed for the last 30 years, are analyzed. It is shown that the changes observed in the air temperature and atmospheric precipitation promote an increase in natural vegetation productivity over approximately 88% of the territory. Minor centers of decreased productivity of ecosystems are found in the central and northeastern districts of European Russia, in the south of Eastern Siberia, and in the Far East. A tendency to climatogenic growth of the soil organic carbon content is detected almost everywhere in the forest, forest-steppe, and steppe Russian zones.
