A dedicated Centre for Climate Change Research (CCCR) to address various scientific issues including impacts on sectors like health, agriculture and water has been set up in IITM, Pune along with necessary manpower, computing, physical infrastructure under the global and regional climate change programme. Major efforts of the climate change research include

1. Two sets of 100-year simulation of the CFS model in a coupled ocean-atmosphere model having 2°and 1° grid scale have been produced. These simulations are being used to test CFS model suitability to predict variability of the Indian Summer Monsoon.
2. Annual Seasonal Monsoon Simulation Experiment has been launched in a Hind-cast mode over a period of 29-Years starting CFS Model with 1st May data fields to run up to 31st October for successive years during 1981-2009.
3. Forecast Mode Experimental Runs are being carried out starting with the 1st day data fields of successive 8-month period (March – October, 2010). The coupled-model output of monsoon rainfall with that of the long-range forecast (LRF) statistical models are being compared.
4. A focused and well-defined roadmap for contributing to the Assessment Report-5 (AR5) of the Intergovernmental Panel on Climate Change (IPCC) is chalked out.

Hadley Centre Coupled Ocean-Atmospheric Climate Model version 3 (Had CM3) is being examined to select potential ensemble member fields, among the 17, which have most closely reproduced the observed summer monsoon climate variables. Six among the 17-ensemble runs of QUMP experiment are found to be reproducing mean summer monsoon climate reasonably well and these fields are used to drive the Regional Climate Model (RCM) – PRECIS to generate 50Km grid scale under A1B Scenario (Medium Emissions) runs over South Asia continuously for the period 1961-2100.

Under the aegis of the Indian Network of Climate Change Assessment (INCCA), a Report, entitled Climate Change & India: A 4X4 Assessment – A Sectoral and Regional Assessment of Impact of Climate Change in 2030s, has been released by the Government during November, 2010. Studies were undertaken in four climate sensitive regions of the country, viz. Himalayan Region, Western Ghats, North Eastern Region, Coastal Areas, assessed impacts in the four sectors viz. agriculture, water, forests and health, have been analysed using RCM fields generated in India.
