    Africa-Gate? U.N. Fears of Food Shortages Questioned

    The U.N.'s controversial climate report is coming under fire -- again --
    this time by one of its own scientists, who admits he can't find any
    evidence to support a warning about a climate-caused North African food
    shortage.

    The statement comes from a key 2007 report to the U.N., and asserts that by
    2020 yields from rain-fed agriculture could be reduced by up to 50% in some
    African countries thanks to climate change.

    But this weekend, a key author of the team behind that report told The
    Sunday Times that he could find no evidence to support his own group's
    claim. The revelation follows the retraction by the Intergovernmental Panel
    on Climate Change (IPCC) of a claim that the Himalayan glaciers might all
    melt by 2035, dubbed 'Glaciergate' by commentators.

    The newest controversial claim could become a very important error in the
    IPCC's reporting, because it comes not only from the IPCC's report on
    climate change impacts -- called Assessment Report 4, or AR4 -- but is also
    repeated in its "Synthesis Report." That report is the IPCC's most
    politically sensitive publication, distilling its most important science
    into a form accessible to politicians and policy makers.

    Its lead authors include IPCC chairman Rajendra Pachauri himself, who has
    quoted it in speeches, as has U.N. secretary-general Ban Ki-moon.

    Speaking at the 2008 global climate talks in Poznan, Poland, Pachauri said:
    "In some countries of Africa, yields from rain-fed agriculture could be
    reduced by 50% by 2020." In a speech last July, Ban said: "Yields from
    rain-fed agriculture could fall by half in some African countries over the
    next 10 years."

    Speaking this weekend, Professor Chris Field, the new lead author of the
    IPCC's climate impacts team, said: "I was not an author on the 'Synthesis
    Report,' but on reading it I cannot find support for the statement about
    African crop yield declines."

    This sort of claim should be based on hard evidence, said Robert Watson,
    chief scientist at Defra, the U.K.'s department for environment food and
    rural affairs, who chaired the IPCC from 1997 to 2002.

    "Any such projection should be based on peer-reviewed literature from
    computer modelling of how agricultural yields would respond to climate
    change. I can see no such data supporting the IPCC report," he said.
