Bottom up efforts, like individuals, cities and states, would be best off just dealing with the effects of climate change. Build taller flood defenses. Build more desalination plants. Change crops. Upgrade AC units. etc. Top down efforts, like global carbon quotas with enforcement via sanctions or even military action, are the only efforts likely to see success. So far, world leaders haven't shown interest in such things, but who knows, as world leaders get old and die and are replaced by the next generation, there might be interest in such a scheme.
