Nature editorial hits IPCC hard: 'It's time for the influential body to uphold its own neutrality standards'

An editorial published in the August 2011 edition of Nature Climate Change is highly critical of the IPCC's use of non-peer-reviewed "grey" literature [such as propaganda from Greenpeace] and that "a Greenpeace campaigner was put in charge of reviewing and highlighting his own work within Working Group III..." leading to the embarrassing and widely debunked claim that 80% of the world's energy could be supplied by renewable energy by 2050.

A second editorial in the same issue states regarding this same conflict of interest, "For a body that represents the state of understanding on one of the most complex and important issues of our time, repeating previously acknowledged mistakes is completely unacceptable."
