Geo-Engineering and Climate Change

From Arnold Kling Go to Greg Mankiw for the pointer. What I would like to know is whether geo-engineering represents a just-in-case technology. That is, if we can execute an Operation Sunscreen that quickly stops temperatures from rising, that would make for a really strong case against sacrificing a lot of GDP through a carbon tax. Because we do not yet know how bad global warming is going to be, the longer we can wait before doing anything about it, the better--but only if we know that we can wait and still do something about it!
