Possible changes of zonal phytocenoses for the territory of European Russia under a 1 °C increase in the annual mean global surface temperature are analyzed from a thermodynamic point of view. Outputs of the atmosphere-ocean general circulation model HadCM3 (Met Office Hadley Centre, United Kingdom) and the intermediate-complexity climate model developed at the Institute of Atmospheric Physics, Russian Academy of Sciences, are used. Model estimates of the annual entropy production by the vegetation cover for the territory under study are obtained for the second half of the 20th century. Changes in the annual entropy production are estimated under possible warming.
