New Delhi, Feb 8 (IANS) After a goof-up in the Intergovernmental Panel on Climate Change's (IPCC) report on melting of Himalayan glaciers, the Prime Minister's Special Envoy on Climate Change Monday called detailed research in India on the impact of global warming in the country.

'We have evidence that climate change in happening but we need more information. More research should be done so that we have precise information about global warming,' said Saran while speaking at a seminar on Impacts of Climate Change on Society.

Saran also lend support to IPCC chairman R.K. Pachauri saying one mistake doesn't mean that the whole report can be discarded.

'He (Pachauri) has played a very important role in raising awareness about climate change in India. He is highly respected internationally and I think one mistake doesn't mean that he should have to step down from his post,' Saran said.

Pachauri has been facing criticism over a blunder in the IPCC's fourth assessment report that said Himalyan glaciers would disappear by 2035, a statement that had not been reviewed by peers as per norms.
