Responding to growing criticism, the Intergovernmental Panel on Climate Change (IPCC) today admitted an error in a working group report that was part of its massive 2007 global review. A statement that the Himalayan glaciers were “very likely” to melt by 2035 was based on “poorly substantiated” estimates, IPCC said. This forecast, which appears to have been based on the non-peer-reviewed work of a single researcher, was challenged publicly last November  by an Indian government report written by geologist Vijay Kumar Raina. In its statement, IPCC, led by Rajendra Pachauri, expressed "regret" for "poor application of well established procedures"  in the drafting of the 2007 working group document.
