IPCC’s AR4 under attack yet again

A Fox News.com article says that some UN claims related to the impact of climate change on the Amazon forest are based on a World Wildlife Fund (WWF) report that was not peer reviewed and only remotely connected to the Amazon.

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.

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."
