'US Climate Policy Bigger Threat to World than Terrorism': "Tony Blair's chief scientist has launched a withering attack on President George Bush for failing to tackle climate change, which he says is more serious than terrorism... Advisers to President Bush have suggested climate change is a natural phenomenon and criticized climate researchers for suggesting that rises in global temperatures are the result of man-made emissions of greenhouse gases such as carbon dioxide. But Sir David says the "causal link" between man-made emissions and global warming is well-established and scientists cannot explain the general warming trend over the past century without invoking human-induced effects... President Bush has said more research on global warming is needed before the US will consider the sort of action needed to comply with the Kyoto protocol, but Sir David says that by then it could be too late. "Delaying action for decades, or even just years, is not a serious option. I am firmly convinced that if we do not begin now, more substantial, more disruptive, and more expensive change will be needed later on.""
