The Inter-Governmental Panel on Climatic Change (!pCe) of the United Nations in its report for 2001 has projected using different models that the globally averaged temperature of the air above the earth's surface might rise by 1.4-5.8°C over the next 100 years (Fig. 1) (!pCC, 2001). The CO2 levels are projected to increase to 388-399 478-1099 by 2100 using different models. For India, the area-averaged annual mean warming by 2020 is projected to be between 1.0 and 1.4°C and between 2.2 to 2.9°C by 2050. Relatively, the increase in temperature would be less in khari! (monsoon season) than in rabi (winter season). The khari! rainfall is expected to increase in most places whereas rabi rainfall may decrease in some areas. The rabi rainfall will, however, have larger uncertainty (Table 1).
