Rich countries are not to blame for global warming but they should still pay more to stop it

An unfortunate side effect of the moralisation of global warming is the blame game. A large number of people seem to think it makes sense to address the enormous problem of global warming by putting various rich countries on trial for their crimes against the atmosphere over the past 200 years. This project is a foolish one, a backwards looking side-show that - perhaps conveniently - distracts political attention from the pragmatic policy debates we need for actually addressing the problem (previously). But even if we were to take it seriously it wouldn't give the answers one might expect.
