See Africagate: top British scientist says UN panel is losing credibility
The most important is a claim that global warming could cut rain-fed north African crop production by up to 50% by 2020, a remarkably short time for such a dramatic change. The claim has been quoted in speeches by Rajendra Pachauri, the IPCC chairman, and by Ban Ki-moon, the UN secretary-general.
This weekend Professor Chris Field, the new lead author of the IPCC’s climate impacts team, told The Sunday Times that he could find nothing in the report to support the claim. The revelation follows the IPCC’s retraction of a claim that the Himalayan glaciers might all melt by 2035, dubbed 'Glaciergate' by commentators.
Someone should remind all of the responsible persons involved in putting together the now much-discredited IPCC report of the old tale about the little boy who cried wolf. The story ends badly for all involved, except for he wolf. The wolf does alright. But the boy, the sheep, and the villagers, not so well.
