Indigenous assessment to be presented to IPCC to report on effect on ocean temperatures, weather patterns Scientists at the Indian Institute of Tropical Meteorology (IITM), Pune, are likely to unveil in December a computerised model that can forecast the impact of climate change on the Indian monsoon until 2100. This model is significant because it is the first time India will be submitting a home-grown assessment to the Intergovernmental Panel on Climate Change (IPCC), a body convened by the United Nations, and hugely influential to policymakers and governments on the risks posed by climate change. A test version of the model is already available on websites of research groups affiliated to the IPCC. The IPCC summarises projections from such models, developed by scientists from around the world, to report on the level of consensus, among scientists, of the extent to which specific pollutants and gases — from carbon dioxide to particulate matter — interfere with weather patterns
