Lecture ERS 482/682 (Fall 2002) Implications – model predictions Increased humidity –Faster movement through hydrologic cycle Higher steady-state air temperature Unequal effects –Most temperature change at high latitudes –Oceans warm more slowly than land Could be severe drought as transition occurs
