Advances in the science and observation of climate change are providing a clearer understanding of the inherent variability of Earth’s climate system and its likely response to human and natural influences. The implications of climate change for the environment and society will depend not only on the response of the Earth system to changes in radiative forcings, but also on how humankind responds through changes in technology, economies, lifestyle and policies (Moss et al 2010).
In this context, a wide range of preparedness measures can be implemented in response to both observed and anticipated climate change and varying effects on locations, sectors and population demographics of the economy. However, the effectiveness of local level preparedness efforts depends on several elements including economics, local politics, leadership, available information, institutional framework and local awareness. There is no easy solution to this global problem. A starting point would be establishing effective climate change governance by linking between international, national climate change policies and decentralization at sub-national governance policies (Habib-Mintz 2008).
Thus, realizing the importance of the role of State government initiatives on climate change and in par with India’s National Action Plan on Climate Change, Department of Environment (DoE), Government of Tamil Nadu has established a Climate Change Cell herein referred as Tamil Nadu State Climate Change Cell (TNSCCC) on 1st December, 2014. The cell provides the central focus for Tamil Nadu State Government’s climate change related initiatives and activities, operating as a unit of the DoE, Government of Tamil Nadu.
