Oops! There go another two bricks, tumbling out of the IPCC wall of deceit on man-made global warming – there is not a lot left now; even the Berlin Wall (to which the AGW construct is ideologically allied) has survived better. Unhappily for Al, Phil, Michael, George and the rest of the scare-mongers, these two discredited components are among the most totemic in the AGW religion.Firstly, a new study, funded by Nasa (which may be feeling the need to rehabilitate itself post-Climategate) has revealed that the ridiculous claim in the notorious IPCC 2007 report that up to 40 per cent of the Amazon rainforest could be drastically affected by even a small reduction in rainfall caused by climate change, so that the trees would be replaced by tropical grassland, is utter nonsense. That assertion has already been exposed as derived from a single report by the environmentalist lobby group WWF.
Now Dr Jose Marengo, a climate scientist with the Brazilian National Institute for Space Research and himself a member of the IPCC, says: “The way the WWF report calculated this 40 per cent was totally wrong, while (the new) calculations are by far more reliable and correct.” These calculations were done by researchers at Boston University and were published in the scientific journal Geophysical Research Letters. They used satellite data to study the drought of 2005, when rainfall fell to the lowest in living memory, and found that the rainforest suffered no significant effects.
