Telegraph:

Dr Rajendra Pachauri, the chairman of the Intergovernmental Panel on Climate Change (IPCC), has been under fire since a report from the charity the WWF was used to make claims about reductions in ice on mountains.
In particular it included the erroneous claim that the Himalayan glaciers would melt by 2035. It was said to be 300 years out and led to accusations that the organisation was cherry-picking evidence to justify its claims.
In a hearing at the InterAcademy Council, an organisation of the world’s science academies which is conducting an independent review of the processes and procedures of the IPCC, Dr Pachauri described the inclusion of the glacier claim as “human failure” which should not have happened.
But the IPCC’s chairman said there was a need to use information which was not from peer-reviewed scientific journals, because in some places that was the only research that had been done.
He said the media and other sections of society had misunderstood the role of such information, labelling it grey literature, “as if it was some form of grey muddied water flowing down the drains”.
Dr Pachauri said academic work being done by bodies including the International Energy Agency, the World Bank, national governments and charities “cannot be ignored”, but had to be closely examined to make sure it was robust.

Really, this should be the end of Pachauri’s tenure with the IPCC.
