Under current climate, the authors estimate the total phytomass of Siberia to be 74.1 {+-} 2.0 Pg. in all four climate change scenarios, the predicted phytomass stock of all colder, northern classes is reduced considerably. Forest-Steppe greatly expands with all GCM`s. A notable feature of these increases is the large introduction of Temperate Forest-Steppe under climate change. Moderate warming associated with the OSU and GISS projections resulted in a 23--26% increase in phytomass, respectively. Great warming associated with the UKMO and GFDL projections resulted in a small 3%--7% increase in phytomass, respectively. Thus, the Siberian phytomass component is sensitive to the degree of climate change, even though all scenarios correspond to the same CO{sub 2} doubling equilibrium.
