there's lots of discussion about how accurate climate models are, but nearly no discussions about the economic models that are used to justify the response. For example, you could reduce car deaths to zero by outlawing all cars, but the costs would outweigh the risks (at least in the mind of most people. If this example doesn't strike you as correct, you can come up with your own one).

Both the climate models and the economic models must be sound to have a sensible idea about how to act.
