Moderate Prometheans

The Prometheus Institute proposes a carbon tax. (Via Ronald Bailey.) Here's an attempt to reconcile global warming skeptics to the idea. And here, in Prometheus' mission statement, are some wise words:

Moderate libertarian views have strong support from American voters, but strangely, few moderate libertarian organizations exist, outside of the Cato Institute and a few others; many other prominent libertarians hold radical, crypto-anarchic viewpoints. By contrast, the Prometheus Institute is concerned only with practical, effective reform for implementation in American public policy. Radical, unworkable abstract ideas are of no value in helping to forward public policy to benefit the true legal freedoms of the people.
