Dr Rajendra Pachauri dismissed calls for him to resign over the Inter-governmental Panel on Climate Change’s retraction of a prediction that Himalayan glaciers could disappear by 2035.

But he admitted that there may have been other errors in the same section of the report, and said that he was considering whether to take action against those responsible.

“I know a lot of climate sceptics are after my blood, but I’m in no mood to oblige them,” he told The Times in an interview. “It was a collective failure by a number of people,” he said. “I need to consider what action to take, but that will take several weeks. It’s best to think with a cool head, rather than shoot from the hip.”
