The Department of Science and Technology (DST) decided to commission a study to assess the climate risks faced by States in India, following an assessment of the global warming risks faced by 12 Himalayan States, discussed at last year's U.N. climate change conference in Poland, that found States such as Assam, Arunachal Pradesh and Uttarakhand vulnerable to climate change. On a scale ranging 0-1, 1 indicating the highest possible level of vulnerability, at the top of the scale were Assam with a score of 0.72 and Mizoram at 0.71, whereas Sikkim, with an index score of 0.42 was relatively less vulnerable.The scores of other states are Jammu & Kashmir (0.6B), Manipur (0.59), Meghalaya and West Bengal (both 0.58), Nagaland (0.57), Himachal Pradesh and Tripura (0.51 both), Arunachal Pradesh (0.47) and Uttarakhand (0.45).
