Another biased IPCC report: This time Greenpeace wrote the report!

I think we need a tad bit of reform on the IPCC...

The world's foremost authority on climate change used a Greenpeace campaigner to help write one of its key reports, which critics say made misleading claims about renewable energy, The Independent has learnt.

The Intergovernmental Panel on Climate Change (IPCC), set up by the UN in 1988 to advise governments on the science behind global warming, issued a report last month suggesting renewable sources could provide 77 per cent of the world's energy supply by 2050. But in supporting documents released this week, it emerged that the claim was based on a real-terms decline in worldwide energy consumption over the next 40 years – and that the lead author of the section concerned was an employee of Greenpeace. Not only that, but the modelling scenario used was the most optimistic of the 164 investigated by the IPCC.

Critics said the decision to highlight the 77 per cent figure showed a bias within the IPCC against promoting potentially carbon-neutral energies such as nuclear fuel. One climate change sceptic said it showed the body was not truly independent and relied too heavily on green groups for its evidence.

The allegations are particularly damaging as they represent the second controversy to hit the IPPC in a matter of years. In 2009, a tranche of emails from the University of East Anglia's Climatic Research Unit were leaked two weeks before the crucial Copenhagen climate summit. Climate change sceptics said they showed scientists manipulating data to talk up the threat of global warming, as well as trying to suppress their critics.
