I reported yesterday on Dr. Richard Norths findings on what he coined “amazongate” related to yet another WWF reference in the IPCC AR4.
Yesterday I sent him a comment from WUWT reader “Icarus” that made a very valid point. However that point drew back the curtain for an even larger problem now uncovered by Dr. North as he writes in:
“We are trying to do the best job we can in assessing the quality information about climate change issues in all its dimensions and some do not like the conclusions of our work. Now it is true we made a mistake around the glacier issue, it is one mistake on one issue in a 3,000 page report. We are going to reinforce the procedures to try this does not happen again.”
So says Jean-Pascal van Ypersele, vice chairman of the IPCC – as retailed by the famous Louise Gray, purveyor extraordinare of WWF press releases – in The Daily Telegraph today. It was simply a “human mistake”, he adds. “Aren’t mistakes human? Even the IPCC is a human institution and I do not know of any human institution that does not make mistakes, so of course it is a regrettable incident that we published that wrong description of the Himalayan glacier,” he says.
So far though, the IPCC is sticking to its legend that this is only “one mistake”, burying its head firmly in the sand and ignoring the growing evidence that the IPCC report is riddled with “mistakes” – to apply that extremely charitable definition.
Another of those “mistakes” is the false claim highlighted in my earlier post on “Amazongate“, where the IPCC has grossly exaggerated the effect of climate change on Amazonian forests, stating “up to 40% of the Amazonian forests could react drastically to even a slight reduction in precipitation” – on the basis of a non peer-reviewed WWF report whose lead author, Andy Rowell, is a free-lance journalist.
However, being “human” myself – although some would hotly dispute that assertion – I appear to have made a mistake in my analysis, charging that in the document referenced by the IPCC, there is no evidence of a statement to support the IPCC’s claim that “40 per cent” of the Amazon is threatened by climate change.”
Actually, that is the charge retailed by James Delingpole and by Watts up with that, whereas what I actually wrote was that the assertion attributed to the author of the WWF report, that “up to 40% of the Amazonian forests could react drastically to even a slight reduction in precipitation” is nowhere to be found in the report.
The WUWT post, however, evoked a response from a commentator, “Icarus”, who noted that there was a reference to a 40% figure references in the WWF report, as follows:
Up to 40% of the Brazilian forest is extremely sensitive to small reductions in the amount of rainfall. In the 1998 dry season, some 270,000 sq. km of forest became vulnerable to fire, due to completely depleted plant-available water stored in the upper five metres of soil. A further 360,000 sq. km of forest had only 250 mm of plant-available soil water left.
That is very much my mistake, having completely missed that passage, thus charging that the IPCC passage was “a fabrication, unsupported even by the reference it gives”.
With that, though, the story gets even more interesting, as the assertion made by Rowell and his co-author Peter Moore, is referenced to an article in the Nature magazine, viz:
