India is in for better monsoons over the next 100 years with the decreasing impact of El Nino and increase in surface air temperature, a scientist said in Chandigarh on Monday.
Most climate models indicate that surface air temperature will increase with rise in green house gases over the Indian region in the next 100 years, which would be accompanied by an increase in monsoon activity, Dr Rupa Kumar Kolli of the Indian Institute of Tropical Meteorology told a plenary session on Global Warming and Environment at the Science Congress in Chandigarh.
Besides, Kolli said, the impact of El Nino, a phenomenon in which the sea surface temperature over the Pacific Ocean rises, was decreasing.
He said India had recorded a 0.4 to 0.6 degree Celsius rise in temperature over 100 years with most of the warming contributed by maximum temperatures while minimum temperatures remained more or less constant.
Participating in the discussion, Dr A P Mitra from the National Physical Laboratory said studies have indicated that the water scarcity in the northwest would increase in the future because of the changing rainfall pattern.
