Abstract

The ways in which the greenhouse effect may affect evapotranspiration (ET) rates are briefly reviewed. ET may change because of atmospheric warming and because of associated changes in other climatic factors. ET rates may also be altered by the stimulation of plant growth and increase in stomatal resistance that occur in response to CO2 enrichment of the atmosphere. The Penman-Monteith model of evapotranspiration was employed with data from four different ecosystems to estimate the possible range of changes in ET which may occur in response to the climatic and plant changes mentioned above. The climatic and plant factors were first varied individually to determine model sensitivity. These factors were then varied simultaneously according to scenarios of climatic change to determine their combined impact on ET. Depending on the ecosystem and on climatic conditions, ET can differ by -20 to +40% from the control case (no climate or plant change).
