Kyoto Is Too Little to Fix Warming, Says U.N. Climate Chief

"My feeling is that we will probably need to do more than most people are talking about" to combat climate change, said Rajendra Pachauri, chairman of the United Nations' Intergovernmental Panel on Climate Change (IPCC). He welcomed ratification of the Kyoto pact by Russia's lower house of parliament, paving the way for the long-delayed 1997 accord to enter into force in the 126 nations that approved it, even though the world's greatest polluter, the United States, pulled out in 2001. "This mustn't lull us into thinking that the problem is solved," Pachauri said. "Kyoto is not enough. We now have to look at the problem afresh." Kyoto is a first step towards curbing emissions of gases like carbon dioxide, mainly from burning fossil fuels, that scientists blame for trapping heat in the atmosphere like the panes of glass in a greenhouse.
