These methods have been significantly improved by fully coupling the hydrologic cycle among land, lake, and atmosphere.94, 95 Without accounting for that cycle of interactions, a study96 concluded that increases in precipitation would be negated by increases in winter evaporation from less ice cover and by increases in summer evaporation and evapotranspiration from warmer air temperatures, under a scenario of continued increases in global emissions (SRES A2 scenario).
Model projections for precipitation changes are less certain than those for temperature.12, 2 Under a higher emissions scenario (A2), global climate models (GCMs) project average winter and spring precipitation by late this century (2071 - 2099) to increase 10 % to 20 % relative to 1971 - 2000, while changes in summer and fall are not expected to be larger than natural variations.
