INDIA often finds itself in the midst of debates on climate change. But there is very little country-specific research available to guide climate-related policy. In 2010, researchers and policy advocates on climate change came together to form a network to promote quality climate research in the country. Three institutes, IIT-Delhi, IIT-Madras and Centre for Science and Environment (CSE), established the Indian Climate Research Network (ICRN). The network boasts over 150 members.
