Currently the land is absorbing about a quarter of anthropogenic СО2 emissions, because uptake by plant photosynthesis is outstripping the respiration from soils. But due to global warming this sink may reverse and continental ecosystems became the source of СО2 due to accelerated decomposition of soil organic matter. Minimal model of biosphere–climate system was developed for investigation conditions for avalanche-like changes, caused by amplification of the positive feedback: «anthropogenic emission of СО2 – temperature increase – additional CO2 emission due to decomposition of soil organics»

Key Words
irreversible biosphere–climate changes, minimal model of biosphere and climate, the worst scenario principle
