If that's true, then it's doesn't take a genius to sugget a multi-pronged strategy.

Carbon taxes and tariffs would work yes. But you're imposing serious costs on people that they haven't shown any desire to support. Further, tariffs would disproportionately impact the poor in the developing world.

I'm 100% against the embargo of Cuba ... but let me use that as an example of: "it's not as if the US hasn't/isn't doing exactly that in other arenas".

But I take your point, and I'm not sure of the solution.

The solution is economic, just not via tariff or tax. Clean energy must supplant dirty energy at scale. The only way for this to happen is to make it cheaper so the developing world will use it instead.
