What would a libertarian do about global warming?

Let's say for a moment, and just for the sake of argument, that human-induced global warming is both proven and a clear menace -- in other words that all the alarmists' claims are correct. What would be the libertarian solution to such a threat?

That's the question being considered in a revealing roundtable at the Reason Foundation's website. The three papers kicking off debate are:

Property Rights Approaches to Global Warming: Scope and Limits
Shikha Dalmia, Editor of Reason Roundtable

The Missing Elements in the "Science" of Global Warming
Donald J. Boudreaux, Chairman of the Department of Economics at George Mason University

The Role of Market Institutions in Enabling Adaptation to Climate, Change
Julian Morris, Director of International Policy Network

As the convenor of the roundtable, Shakia Dalmia says:

While it is difficult to use property rights to protect the global commons and avert climate change, it does not follow that government regulations are therefore the answer.

So what would be the answer? You can read the debate (and join in yourself) at the main roundtable page here, or at Ronald Bailey's summary and follow-up here.
