I’m not seeing much difference in ‘definitedness’ between personal behavior change and “world organization that sets per-country targets” unless it’s just that solving global warming necessarily must involve global government.
Yes, I think some minimal level of global coordination may be necessary, and is very likely to play a significant causal role in the eventual outcome. For example, I think the US should feel more comfortable investing in a certain amount of carbon emissions reduction/sequestration knowing that other countries are officially supposed to also do their part.
In contrast, whether individuals focus any effort on reducing their footprint outside of their main system of economic incentives is definitely not going to have a causal role on the outcome.
