Atmospheric CO2 enrichment tends to lower tree stomatal conductances and this phenomenon reduces tree transpiration rates. Short-term CO2 enriched plants have more leaf area from which water may be lost. In spite of rise in the potential evaporation (15 % since 1901 according to Lapin et al. 1994) it is expected that real evapotranspiration from forests will be lower as a result of decreased stomatal conductance. However, increasing CO2 concentration and temperature have contradictory effects on evapotranspiration. Decrease of stomata conductance neutralizes the influence of increasing temperature and decreasing precipitation
