Yet Another Reason To Bring Global Climate Change Debate Back To Reality

What happens if one country decides to start geoengineering on its own?

Getting nations to agree to cut their greenhouse pollution has proved to be the ultimate free-rider problem, as the biggest nations must all cooperate or the planet will keep getting warmer. The Pinatubo option creates the opposite dilemma: As the discussions in Lisbon made clear, any of a dozen nations could change the global temperature all by itself.

I'm huge on the idea of Unintended Consequences. It's a key feature of many of my lectures. This one's a whopper. Instead of nuclear blackmail, we could face climatological blackmail over global warming which may prove ultimately to have been Not Entirely Our Fault.
