A Calm Voice in a Heated Debate

Standing in the practical middle is Bjorn Lomborg, the free-thinking Dane who, in "The Skeptical Environmentalist" (2001), challenged the belief that the environment is going to pieces. Mr. Lomborg is now back with "Cool It," a book brimming with useful facts and common sense. Mr. Lomborg -- "liberal, vegetarian, a former member of Greenpeace," as he describes himself -- is hard to fit into any pigeonhole. He believes that global warming is happening, that man has caused it, and that national governments need to act. Yet he also believes that Al Gore is bordering on hysteria, that some global-warming science has been distorted and hyped, and that the Kyoto Protocol and other carbon-reduction schemes are a terrible waste of money. The world needs to think more rationally, he says, about how to tackle this challenge.
Mr. Lomborg starts by doing what he does best: presenting a calm analysis of what today's best science tells us about global warming and its risks. Relying primarily on official statistics, he ticks through the many supposed calamities that will result from a hotter planet -- extreme hurricanes, flooding rivers, malaria, heat deaths, starvation, water shortages. It turns out that, when these problems are looked at from all sides and stripped of the spin, they aren't as worrisome as global-warming alarmists would suggest. In some cases, they even have an upside.
Take flooding. After the 2002 floods of Prague and Dresden, Tony Blair, Jacques Chirac and Gerhard Schroeder all argued that the floods proved the need for Western governments to commit themselves to Kyoto. Mr. Lomborg agrees that global warming increases precipitation. Yet to the extent that more precipitation has already increased river flows, it has done so largely in the fall, when rivers are at low levels and there is little risk of flood. Truly bad floods have historically accompanied colder climates, since plentiful snow and a late thaw produce ice jams that block rivers and produce high water levels. These sorts of floods have in fact decreased in the 20th century, at least in part because of global warming.
The picture is the same for other "disasters." Yes, sea levels will rise -- probably about a foot over this century. But they have already risen a foot since 1860, and the world has coped. Yes, more people will die from heat; but significantly more people will not die from cold. Yes, glaciers will melt, but they'd be melting to some degree in any event, and in the meantime this melting provides extra water for some of the world's poorest people. (The Himalayan glaciers on the Tibetan plateau -- the biggest ice mass outside the Antarctic and Greenland -- are the source of rivers that reach 40% of the world's population.) Such a nuanced look at the good and bad of global warming gives Mr. Lomborg a chance to pursue his bigger theme: Anti-warming policies (like those of the Kyoto Protocol) that require energy taxes or other checks on economic dynamism are inefficient and even harmful. They serve as short-term ways of dealing with what is a complex and long-term problem. They cost a lot now and yet do little to reduce global temperatures in 100 years' time.

As for the long term, Mr. Lomborg argues that governments do have a role to play. But he presents a real inconvenient truth: The world has been dependent on fossil fuels for generations, and it is ludicrous to believe that it will end that dependency in a few decades. Yet only a drastic reduction in fossil-fuel use will cut carbon-dioxide emissions enough to stop or significantly slow climate change. Rather than governments imposing costly energy taxes to little benefit, Mr. Lomborg argues, they should fund research programs aimed at finding breakthrough technologies.
