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."
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.
