Description :
Changes of forest biomass are estimated for time intervals 1860-1900, 1900-1950 and 1950-1980. The estimations are based on the inventory data of the world forest storage. Carbon cycle modelling and a simple equation for mass balance of the stable U3C isotope permitted to derive the value of planetary biomass changes using the data on the U3C/U2C ratio in tree rings. According to both methods the planetary biomass decreased during 1860-1980 about (30...60). 10U2 kg of carbon, while during 1956-1980 not more than about (15...20).10U2 kg. The biospheric source of carbon had released about 1/3 to 1/2 of the amount of fossil fuel CO2 during the whole period of 120 years.
