As per the Indian Network for Climate Change Assessment (INCCA) studies the projected changes in 2030s in India are: (Source: INCCA REPORT #2, CLIMATE CHANGE AND INDIA:A 4X4 ASSESSMENTA SECTORAL AND REGIONAL ANALYSIS FOR 2030S, Nov.2010)

• Coupled model simulations from IPCC AR4 show large uncertainty in simulating Indian summer monsoon rainfall, however a MME of 10 selected models give reasonably good representation of monsoon though with a dry bias.
• MME projects around 10% increase in the Indian monsoon rainfall over central and peninsular India in 2030's. The expected change in the rainfall is within the current monsoon variability and there are large model to model differences making these projected changes to be lesser confident.
• MME projects 1.5-2°C warming in the annual mean temperature over the Indian landmass while winter (Jan-Feb) and spring (Mar-Apr-May) seasons show higher warming.
• High resolution regional climate model ‘PRECIS’ shows good skill in representing smaller scale features of monsoon.
• The projections of PRECIS in 2030's indicate 3-7% increase in all-India summer monsoon rainfall.
• The annual mean surface air temperature may rise from 1.7°C to 2°C by 2030's as indicated by the three simulations
• The regional climate model simulations indicate that the cyclonic disturbances over Indian oceans during summer monsoon are likely to be more intense and the systems may form slightly to the south of normal locations.
• The ensemble mean changes in the monsoon rainfall are in the range of 2 to 12% while the annual temperature changes are of the order of 1.4 to 1.9oc, however the individual simulations show large differences.
