NEW DELHI Prime Minister Narendra Modi on Wednesday reconstituted a high-level advisory group on climate change, ahead of a crucial UN meet on global warming in Peru.

While the government retained TERI chairperson R K Pachauri, Nitin Desai and retired diplomat Chandrasekhar Dasgupta as nongovernment members of the 18- member team, environmentalist Sunita Narain and industrialist Ratan Tata have been dropped.

Both Tata and Narain were members of the panel constituted by the UPA government in 2007. The advisory body had not met for the past three years.

Headed by Modi, the reconstituted council, tasked with evolving a coordinate national action for assessment of climate change, also saw increase in the ministerial strength with induction of Urban Development Minister and Coal Minister as members.
