A particularly fertile place to find bogus climate change claims has been the United Nations climate change panel, the IPCC. Two weeks ago, The IPCC was forced to retract a warning that climate change was likely to melt the Himalayan glaciers by 2035. That warning was also based on claims in a WWF report, which wasn't peer reviewed. The data in the report came from a student's dissertation and a mountain climbing magazine. There was also the bogus claim that climate change may be increasing the severity and frequency of natural disasters such as hurricanes and floods. The latest UN climate change hoax is a report that global warming is causing the rainforests to disappear.
A STARTLING report by the United Nations climate watchdog that global warming might wipe out 40% of the Amazon rainforest was based on an unsubstantiated claim by green campaigners who had little scientific expertise.Just like the glacier report the IPCC is relying on unsubstantiated data,that hasn't been peer-reviewed. In this case it is even worse, they took data meant for a different purpose and applied it to climate change.
The Intergovernmental Panel on Climate Change (IPCC) said in its 2007 benchmark report that even a slight change in rainfall could see swathes of the rainforest rapidly replaced by savanna grassland.
The source for its claim was a report from WWF, an environmental pressure group, which was authored by two green activists. They had based their “research” on a study published in Nature, the science journal, which did not assess rainfall but in fact looked at the impact on the forest of human activity such as logging and burning. This weekend WWF said it was launching an internal inquiry into the study.
....Scientists fear the controversies will be used by climate change sceptics to sway public opinion to ignore global warming — even though the fundamental science, that greenhouse gases can heat the world, remains strong.Not quite, because many elements of the fundamental science including the famous hockey stick have been proven to be false, despite the fact that Osama Bin Laden is now a big fan.
The latest controversy originates in a report called A Global Review of Forest Fires, which WWF published in 2000. It was commissioned from Andrew Rowell, a freelance journalist and green campaigner who has worked for Greenpeace, Friends of the Earth and anti-smoking organisations. The second author was Peter Moore, a campaigner and policy analyst with WWF.
In their report they suggested that “up to 40% of Brazilian rainforest was extremely sensitive to small reductions in the amount of rainfall” but made clear that this was because drier forests were more likely to catch fire.
The IPCC report picked up this reference but expanded it to cover the whole Amazon. It also suggested that a slight reduction in rainfall would kill many trees directly, not just by contributing to more fires.
It said: “Up to 40% of the Amazonian forests could react drastically to even a slight reduction in precipitation; this means that the tropical vegetation, hydrology and climate system in South America could change very rapidly to another steady state. It is more probable that forests will be replaced by ecosystems that have more resistance to multiple stresses caused by temperature increase, droughts and fires, such as tropical savannas.”
Simon Lewis, a Royal Society research fellow at Leeds University who specialises in tropical forest ecology, described the section of Rowell and Moore’s report predicting the potential destruction of large swathes of rainforest as “a mess”.
“The Nature paper is about the interactions of logging damage, fire and periodic droughts, all extremely important in understanding the vulnerability of Amazon forest to drought, but is not related to the vulnerability of these forests to reductions in rainfall,” he said.
“In my opinion the Rowell and Moore report should not have been cited; it contains no primary research data.”
WWF said it prided itself on the accuracy of its reports and was investigating the latest concerns. “We have a team of people looking at this internationally,” said Keith Allott, its climate change campaigner.
Scientists such as Lewis are demanding that the IPCC ban the use of reports from pressure groups. They fear that environmental campaign groups are bound to cherry-pick the scientific literature that confirms their beliefs and ignore the rest.As we have learned in the climategate mess and now this IPCC hoax, anxious to keep their bogus science going, the climate change scientists will use any dubious research that supports their claims and will toss out peer reviewed research that disputes their claims. This is not real science it is political advocacy with the ultimate objective to redistribute income from the major economies to the third world nations.
It was exactly this process that lay behind the bogus claim that the Himalayan glaciers were likely to melt by 2035 — a suggestion that got into another WWF report and was then used by the IPCC.
