The modeling of the global biogeochemical cycle of carbon and nitrogen against the background of global warming and other anthropogenic impacts on the biosphere is carried out. It is shown that in the process of absorption of anthropogenic CO2 emissions into the atmosphere during global warming, the nitrogen cycle is significantly intensified and contributes to more efficient absorption of emissions. The greater the dependence of productivity on nitrogen nutrition, the bigger the degree of carbon absorption and, thus, the larger the degree of compensation of the investigated effects. Generally, soil absorbs a significant share of carbon dioxide emissions and therefore holds much significance in absorption. The role of litter is relevant in absorbing emissions. Having 10 times less mass than humus, it absorbs more carbon than humus.
