Indigenous model developed to predict impact of climate change on monsoon

Union Minister of State (Independent Charge) Science & Technology; Minister of State (Independent Charge) Earth Sciences; MoS PMO, Personnel, Public Grievances, Pensions, Atomic Energy and Space, Dr Jitendra Singh said that Government has developed an indigenous climate model to predict the impact of climate change on monsoon in the country. In a written reply to a question in the Rajya Sabha today, he said, a state-of-the-art Earth System Model (ESM) has been developed at the Centre for Climate Change Research (CCCR), Indian Institute of Tropical Meteorology (IITM) under the Ministry of Earth Sciences (MoES).

The model development was done by the scientists at IITM Pune in collaboration with the international research community. This model is a state-of-the-art climate model with components of the atmosphere, ocean including deep ocean circulation, Arctic and Antarctic sea-ice and ocean biogeochemistry.

This Earth System Model, known as the IITM-ESM, is the first climate model from South Asia that has contributed to the Intergovernmental Panel on Climate Change (IPCC) sixth assessment report (AR6) and participated in the Coupled Model Inter-comparison Project –Phase 6 (CMIP6) experiments.

The IITM-ESM has capabilities to address key questions concerning the science of climate change, including reliable projections of the global and regional climate, Indian monsoon, hydrological cycle, sea-level changes, tropical ocean atmosphere processes in a changing climate.
