Cafe Hayek: Let's Have Less Hot Air About Global Warming

Let's grant (if just for the sake of argument) that environmental scientists have proved that Earth's ideal average temperature was reached about a century ago and that the temperature is rising because of human activity ("Just the facts," Op-Ed, yesterday).

The truth remains that these scientists have no expertise to judge whether government can be trusted with the power and resources to "combat" global warming. Nor can these scientists tell us how a free market likely would deal with global warming's consequences.

Contrary to widespread belief, environmental scientists can legitimately say nothing about whether, or how, to respond to global warming.
