Tim Yeo, the deep-green chairman of the UK House of Commons Energy and Climate Change Committee has called for Rajendra Pachauri to resign.
"I’m afraid I think Dr Pachauri should resign. Firstly he personally has lost credibility, particularly in relation to his claim about the melting of the Himalayan glaciers in the next 30 years," he told the BBC.
He added: "It’s vital that this body is led by someone whose academic and intellectual credentials are unquestioned and I’m afraid that can no longer be said of him."
Apparently Sir Brian Hoskins has also called for Pachauri to step down.
