V.K. Raina, the former Deputy Director-General of the Geological Survey of India -- whose research document on the Himalayan glaciers debunked the claims of the Intergovernmental Panel on Climate Change (IPCC) that these glaciers would disappear by 2035 -- is not satisfied by the regret expressed by the United Nations agency.

“I want a personal apology from the IPCC chairperson R.K. Pachauri who had described my research as voodoo science,” Mr. Raina told The Hindu over phone from Panchkula. “Forget IPCC, Dr. Pachauri has not even expressed regret over what he said after my report -- Himalayan Glaciers: a state-of-art review of glacial studies, glacial retreat and climate change -- was released in November last year.”

With over 100 scientific papers and three books to his credit, Mr. Raina said he had not read the Fourth Assessment Report of the IPCC that made the prediction on melting of the Himalayan glaciers, but read the contents only from what was published in newspapers and magazine.

“But all along I knew that this was not based on facts. During my 50 years of research and several expeditions to the region, I never found anything as sensational as was predicted in the IPCC, but no one heard me then.”

It was only after he was asked by the Minister of Environment and Forests to come out with a report that a global debate was initiated on the issue.
