The head of the Intergovernmental Panel on Climate Change (IPCC) has said the organisation needs to learn from recent criticisms and modernise its workings.

But despite making an error over Himalayan glacier melt in its landmark 2007 report, the panel’s basic conclusions remain sound, Pajendra Pachauri said speaking at the opening session of a UN-commissioned review into the IPCC’s workings.

The review is due to hear from some of the IPCC’s critics in coming months.
