单选题It seems impossible to have an honest conversation about global warming. I say this after diligently perusing the British government's huge report released last week by Sir Nicholas Stern, former chief economist of the World Bank and now a high civil servant. The report is a masterpiece of misleading public relations. It foresees dire consequences if global warming isn't curbed: a worldwide depression and flooding of many coastal cities. Meanwhile, the costs of minimizing these awful outcomes are small: only 1 percent of world economic output in 2050. No sane person could fail to conclude that we should conquer global warming instantly, if not sooner. Who could disagree? Well, me. Stem's headlined conclusions are intellectual fictions. They're essentially fabrications to justify an aggressive anti-global-warming agenda. The danger of that is that we'd end up with the worst of both worlds: a program that harms the economy without much cutting of greenhouse gases. Let me throw some messy realities onto Stern's tidy picture. In the global-warming debate, there's a big gap between public rhetoric and public behavior. Greenhouse emissions continue to rise despite many earnest pledges to control them. Just last week, the United Nations reported that of the 41 countries it monitors (not including most developing nations), 34 had increased greenhouse emissions from 2000 to 2004. These include most countries committed to reducing emissions under the Kyoto Protocol. Why is this? In rich democracies, policies that might curb greenhouse gases require politicians and the public to act in exceptionally "enlightened" ways. They have to accept "pain" now for benefits that won't materialize for decades, probably after they're dead. And even if rich countries cut emissions, it won't make much difference unless poor countries do likewise and so far, they've refused because that might jeopardize their economic growth and poverty-reduction efforts. The notion that there's only a modest tension between suppressing greenhouse gases and sustaining economic growth is highly dubious. Stern arrives at his trivial costs—that 1 percent of world GDP in 2050—by essentially assuming them. His estimates presume that, with proper policies, technological improvements will automatically reconcile declining emissions with adequate economic growth. This is a heroic leap. To check warming, Stern wants annual emissions 25 percent below current levels by 2050. The IEA projects that economic growth by 2050 would more than double emissions. At present, we can't bridge that gap. The other great distortion in Stern's report involves global warming's effects. No one knows what these might be, because we don't know how much warming might occur, when, where, or how easily people might adapt. Stern's horrific specter distills many of the most terrifying guesses, including some imagined for the 22nd century, and implies they're imminent. The idea is to scare people while reassuring them that policies to avert calamity, if started now, would be fairly easy and inexpensive.

单选题When Dr. John W. Gofman, professor of medical physics at the University of California and a leading nuclear critic, speaks of "ecocide" in his adversary view of nuclear technology, he means the following. A large nuclear plant like that in Kalkar, the Netherlands, would produce about 200 pounds of plutonium each year. One pound, released into the atmosphere, could cause 9 billion cases of lung cancer. This waste product must be stored for 500,000 years before it is of no further danger to man. In the anticipated reactor economy, it is estimated that there will be 10,000 tons of this material in Western Europe, of which one table-spoonful of plutonium-239 represents the official maximum permissible body burden for 200,000 people. Rather than being biodegradable, plutonium destroys biological properties. In 1972 the .U.S. Occupational Safety and Health Administration ruled that the asbestos level in the work place should be lowered to 2 fibers per cubic centimeter of air, but the effective date of the ruling has been delayed until now. The International Federation of Chemical and General Workers' Unions report that the 2-fiber standard was based primarily on one study of 290 men at a British asbestos factory. But when the workers at the British factory had been reexamined by another physician, 40--70 percent had X-ray evidence of lung abnormalities. According to present medical information at the factory in question, out of a total of 29 deaths thus far, seven were caused by lung cancer. An average European or American worker comes into contact with six million fibers a day. "We are now, in fact, finding cancer deaths within the family of the asbestos worker," states Dr. Irving Selikoff, of the Mount Sinai Medical School in New York. It is now also clear that vinyl chloride, a gas from which the most widely used plastics are made, causes a fatal cancer of the blood-vessel cells of the liver. However, the history of the research on vinyl chloride is, in some ways, more disturbing than the "Watergate cover- up. " "There has been evidence of potentially serious disease among polyvinyl chloride workers for 25 years that has been incompletely appreciated and inadequately approached by medical scientists and by regulatory authorities," summed up Dr. Selikoff in the New Scientist. At least 17 workers have been killed by vinyl chloride because research over the past 25 years was not followed up. And for over 10 years, workers have been exposed to concentrations of vinyl chloride 10 times the "safe limit" imposed by Dow Chemical Company.
