I agree. China is either going to require us to find a real diplomatic solution, or get so good at producing technology that removes carbon from the environment sustainably, at scale, that we can simply suck up other countries' excess carbon. Either way, these will be expensive and the political will for such solutions is probably not here in our current political system. I commented further down about needing to address political corruption first and foremost (removing "lobbyists", overturning CU, etc) - I think this will be an important step in producing a political system that will even allow us to effectively address climate change in the first place.
