U.N.'s Global Warming Report for Rainforest Claims Under Fresh Attack in amazon forest.


A United Nations report on climate change that has been lambasted for its faulty research is under new attack for yet another instance of what its critics say is sloppy science -- adding to a growing scandal that has undermined the credibility of scientists and policymakers who back the U.N.'s findings about global warming.

In the Fourth Assessment Report (AR4), issued in 2007 by the U.N.'s Intergovernmental Panel on Climate Change (IPCC), scientists wrote that 40 percent of the Amazon rainforest in South
America was endangered by global warming.

The IPCC report states that "up to 40 percent of the Amazonian forests could react drastically to even a slight reduction in precipitation" -- highlighting the threat climate change poses to the Earth. The report goes on to say that "it is more probable that forests will be replaced by ecosystems ... such as tropical savannas."

But it has now been revealed that the claim was based on a WWF study titled "Global Review of Forest Fires," a paper barely related to the Amazon rainforest that was written "to secure essential policy reform at national and international level to provide a legislative and economic base for controlling harmful anthropogenic forest fires.
c, a blog skeptical of global warming, uncovered the WWF association. It noted that the original "40 percent" figure came from a letter published in the journal Nature that discussed harmful logging activities -- and again had nothing to do with global warming.

The reference to the Brazilian rainforest can be found in Chapter 13 of the IPCC Working Group II report, the same section of AR4 in which claims are made that the Himalayan glaciers are rapidly melting because of global warming. Last week, the data leading to this claim were disproved as well, a scandal being labeled "glacier-gate" or "Himalaya-gate."

The Himalaya controversy followed another tempest -- the disclosure of e-mails that suggested that leading global warming scientists in the U.K. and the U.S. had conspired to hide a decline in global temperatures.
