The great global warming collapse - Margaret Wente
As the science scandals keep coming, the air has gone out of the climate-change movement
In 2007, the most comprehensive report to date on global warming, issued by the respected United Nations Intergovernmental Panel on Climate Change, made a shocking claim: The Himalayan glaciers could melt away as soon as 2035.
These glaciers provide the headwaters for Asia's nine largest rivers and lifelines for the more than one billion people who live downstream. Melting ice and snow would create mass flooding, followed by mass drought. The glacier story was reported around the world. Last December, a spokesman for the World Wildlife Fund, an environmental pressure group, warned, “The deal reached at Copenhagen will have huge ramifications for the lives of hundreds of millions of people who are already highly vulnerable due to widespread poverty.” To dramatize their country's plight, Nepal's top politicians strapped on oxygen tanks and held a cabinet meeting on Mount Everest.
But the claim was rubbish, and the world's top glaciologists knew it. It was based not on rigorously peer-reviewed science but on an anecdotal report by the WWF itself. When its background came to light on the eve of Copenhagen, Rajendra Pachauri, the head of the IPCC, shrugged it off. But now, even leading scientists and environmental groups admit the IPCC is facing a crisis of credibility that makes the Climategate affair look like small change.
“The global warming movement as we have known it is dead,” the brilliant analyst Walter Russell Mead says in his blog on The American Interest. It was done in by a combination of bad science and bad politics. Read more.
