Boasting about imposing "mandatory reductions" of any kind is frighteningly Gore-ific. As Bush himself reminded Gore during the campaign, the jury is still out on the primary cause of global warming (human or natural) and whether the effects might actually do more good than harm. And what exactly does Bush mean when he says the "spirit" of Kyoto is "fine"? The spirit of Kyoto is infected with what environmentalists call the "precautionary principle." This is the idea that nothing should be used, sold, emitted or otherwise approved by the world's governments until and unless it's proven safe. If we had applied that cowering standard in the past, we wouldn't have open-heart surgery, penicillin, skyscrapers or the combustion engine. Too much caution can be as dangerous as too little. And spending billions of dollars reducing the theoretical risks of global warming means fewer resources for the real and deadly environmental risks that now plague underdeveloped nations -- like diarrhea and malaria. Bush was supposed to restore rationality to America's approach to environmental risk in the modern world. Instead, he has sought vainly to score points with soccer moms, Sierra Club dads and MTV deadheads. The result is a pale green policy mish-mash of environmental guacamole that's thoroughly indigestible.
