Another IPCC error

Another alarming prediction in the IPCC report on climate change has been shown to be bogus. A finding that much of the Amazon rainforest is endangered actually referred to logging, not climate change:

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.

But that assertion was discredited this week when it emerged that the findings were based on numbers from a study by the World Wildlife Federation that had nothing to do with the issue of global warming — and that was written by a freelance journalist and green activist. . .

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.”

EUReferendum, 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.

If you’re counting, that’s three errors in the IPCC now (that we know of), all resulting from faulty scholarship.
