Biogeophysical versus biogeochemical feedbacks of large‐scale land cover change

摘要: Large-scale changes in land cover affect near- surface energy, moisture and momentum fluxes owing to structure (referred as biogeophysical effects) the atmospheric CO2 concentration biomass (biogeochemical effects). Here we quan- tify relative magnitude of these processes well their synergisms by using a coupled atmosphere-biosphere-ocean model intermediate complexity. Our sensitivity studies show that tropical deforestation tends warm planet because increase hence, at- mospheric radiation, outweighs effects. In mid high northern latitudes, however, biogeophysi- cal processes, mainly snow-vegetation-albedo feedback through its synergism with sea-ice-albedo feedback, win over biogeochemical thereby eventually leading global cooling case warming, afforestation.
