Paul Krugman's introduction to climate economics
Once you filter out the noise generated by special-interest groups, you discover that there is widespread agreement among environmental economists that a market-based program to deal with the threat of climate change — one that limits carbon emissions by putting a price on them — can achieve large results at modest, though not trivial, cost. There is, however, much less agreement on how fast we should move, whether major conservation efforts should start almost immediately or be gradually increased over the course of many decades.
In what follows, I will offer a brief survey of the economics of climate change or, more precisely, the economics of lessening climate change. I’ll try to lay out the areas of broad agreement as well as those that remain in major dispute. First, though, a primer in the basic economics of environmental protection.
That's from Paul Krugman's sweeping overview of the economics of climate change. Highly recommended.
