In addition to direct cost-effectiveness calculations for the present generation as StevenKaas recommends, I would recommend direct cost-effectiveness calculations for the long-term future. Here is an example where I compare AI and alternative foods to address agricultural catastrophes. It would not take very much work to use that framework for conventional emissions reductions for climate change. However, as others have pointed out, because emissions reductions are so expensive, they are unlikely to be competitive cost-effectiveness. Solar radiation management (SRM) (as opposed to non SRM geoengineering techniques such as CO2 air capture) has the potential of being much more cost effective, but it has its own risks, such as double catastrophe.
