Re: Oh, suddenly you like climate modelling.
I'm saying that we shouldn't be using 'climate change' as a policy driver at all, because we simply do not know enough to make reliable predictions.
By comparison to our current climate models, the other models you mentioned there are extremely good, giving results many orders of magnitude more reliable, precise and accurate.
However, we do know that the oil is going to run out relatively soon (and long before that it's going to become ruinously expensive), we do know that the other emissions (not CO2, the NOX, SOX etc) from most fossil fuels are toxic to humans, plants and animals and so it is clear that we should be reducing our reliance and the absolute amount of those burned.
It's just that CO2 is not the reason why, and thus (for example) replacing tungsten lighting with mercury-based is not a sane idea.
