Released on August 30 2000, this 34-page report from the World Wildlife Fund (WWF) warns that "global warming could fundamentally alter one third of plant and animal habitats by the end of this century, and cause the eventual extinction of certain plant and animal species." According to the report, the danger is greatest in the northern latitudes of Canada, Russia, and Scandinavia, where warming is predicted to be the most rapid, destroying up to 70 percent of habitat. In many other areas it predicts local species loss of up to 20 percent. These predictions are based on "a moderate estimate that concentrations of carbon dioxide (CO2) in the atmosphere will double from pre-industrial levels during this century." However, as the press release notes, some have projected a three-fold increase in concentrations by 2010 unless corrective action is taken. The full text of the report is available in .pdf or Word format at the site, along with an executive summary, conclusions, and discussion of the methods used to create the report.
