This depends on how you define cost and benefit. Remember the cost of doing nothing is
Rising waters (more flood defences or flood insurance going up)
What is the cost when bayfromt SV property is flooded and cant be pumped out? What is the financial value of a species disappearing? What is the value of the oceans and the coral reefs that are being bleached by acid?
Compare that to the cost of switching to renewables lifestyle that can at least be quantified. Options are likely to get more and more expensive (it would have been cheaper 50 years ago than now even with our better tech) it's simply a matter of people putting enough money in to a) clean energy (because the more cheap clean energy we have the more viable other options like carbon capture becomes) and b) simply funding mitigating technologies.
It is quite possibly too late, we may have irreversibly damaged the climate to the point, where even a 100% switch off of co2 tomorrow would simply be too little, too late. Govs didn't introduce punishing taxes and subsidies for the right tech when they knew there was a problem (who votes for raising taxes?) So that's it.
