The unequivocal warming of the climate system is now evident from observations of increases in global average air and ocean temperatures, widespread melting of snow and ice, and rising global average sea level and could cause irreversible damage to earth system and the impact would be particularly severe in the tropics (IPCC 2007), which mainly consist of developing countries, including India. Realizing the importance of the impact of climate change, Anna University Chennai has initiated exclusive climate change research centre the "Centre for Climate Change and Adaptation Research (CCC&AR)" for the first time in the country. The Centre was inaugurated on March 28, 2008 by Noble Laureate Dr. R.K. Pachauri and has been effectively functioning thereafter.
The new Centre for Climate Change and Adaptation Research will bring together all the scientific community, government agencies, National research institutes and other universities with an integrated research programme addressing the national issues on climate change aspects, from its causes to its impacts on community, ecosystems, public health, the built environment and the economy. It will become the focal point for a diverse national network of researchers from other universities and major governmental groups. Unlike other disciplines CCC&AR require multidisciplinary approach integrating various field such as Atmosphere, Water management, Agriculture, Forestry and Biodiversity, Oceanography and Coastal Studies, Geology and Soil Science, Remote Sensing and GIS, Energy, Economics and Social studies.
