Evidence for man-made climate change getting stronger: U.N. | Reuters
(Reuters) - Evidence that global warming is man-made is getting stronger, the head of a U.N. panel of climate scientists said, in a further blow to skeptics who argue rising temperatures can be explained by natural variations.
Rajendra Pachauri spoke on the sidelines of a conference in Qatar where 200 nations are trying to reach a deal to cut emissions of greenhouse gases to avert floods, droughts, heat waves and mounting sea levels.
The influential U.N. climate panel said the probability human activity was the main cause of climate change was "at least 90 percent" in its last report in 2007.
Pachauri told Reuters late on Wednesday he expected the panel would raise the level of that likelihood even higher in its next report, due in 2013.
Pachauri said that Kyoto still seemed a good idea. "It's the only show in town. Why give it up?" he said.
