Warning: Stolen Content Ahead

Found this article recently while browsing the web. I'd say that Roberts' ideas about systems that result from human action but not human design certainly apply to global climate change, our favorite topic of the moment. Alex Taborrak also gets at the same subject, his point being more that you get unintended consequences when a fairly simple system (government) tries to regulate a complex one (the economy). So assuming that we're looking for different government regulations to tackle global climate change, is there any way to prepare for the unavoidable consequences?
