onal debate over what to do, if anything, about the increasing concentration of greenhouse gases in the atmosphere has become less a debate about scientific or economic issues than an exercise in political theater. The reason is that the issue of global climate change is pregnant with far-reaching implications for human society and the kind of world our children will live in decades from now.
Introducing nuance and clear-headed reason to this debate is something of a struggle. As Cato Institute chairman William Niskanen has noted, for any international action to merit support, all of the following propositions must be proven true:
A continued increase in the emission of greenhouse gases will increase global temperature.
An increase in average temperature will generate more costs than benefits.
Emissions controls are the most efficient means to prevent an increase in global temperature.
Early measures to control emissions are superior to later measures.
Emissions controls can be effectively monitored and enforced.
Governments of the treaty countries will approve the necessary control measures.
Controlling emissions is compatible with a modern economy.
The case for any one of those statements is surprisingly weak. The case for a global warming treaty, which depends on the accuracy of all those statements, is shockingly weak. My talk this afternoon will concentrate on a few of the most important of those propositions.
