> Right now the attitude is "If the US, with all its riches and pre-existing contributions to emissions, can't be bothered to do anything, why should we?"
Okay, now the attitude of China will be "We're still at half the CO2 emissions per capita as the US, and we haven't had our full modernization yet." Then there is India who presumably want to emerge from third world conditions for most of the country, then Africa and so on. People are really really good at morally justifying their best short term interests.
I'm just really skeptical that "moral authority" can ever work as a motivator when the actors are huge countries.
> It's totally possible to prevent an economic disadvantage vs China and the rest of the world: tariffs. Countries with carbon taxes can form a tariff bloc against countries without them.
Tariffs aren't working so well for Trump though, are they? Forming the large bloc is the tricky part. But I certainly agree, the main problem here is global cooperation, getting the whole world to make some short term economic sacrifices together.
Honestly, just getting an agreement on a framing that this (global cooperation) is the biggest problem, rather than moralizing against individuals for leaving lights on and driving too much (etc), would be a tremendous step toward progress imo.
First we need global cooperation and agreement on the issue and goals. Then laws that create better incentive structures. Supplement that with better clean energy tech and more acceptance of large scale nuclear energy research and development. Pump a whole bunch of research dollars into nuclear, fusion power, and geoengineering. (This is far far more important than LHC, LIGO, James Webb telescope, funding should be much higher than those.) Figure out what the heck to do about Middle Eastern oil and it being the primary economy of so many countries. Then we're getting somewhere, perhaps!
