There may be a shorter term empirical question here. Given the will, I think eliminating the carbon emissions is technically easier that a lot of people think. I think there are techncial means for the rich nations to eliminate their emissions essentially zero dollar cost - though at the quite extensive poltical cost of a really increased public works budget, some tough efficiency regulations, and certain forms of revenue neutral green taxes. What prevents poor nations from doing something similar is lack of capital. But I can imagine a scenario where the entire poor nation debt (not just that of the poorest of the poor ) is forgiven and really massive aid given in return for reduced carbon emissions. The politics of that seems unlikely, but not unimaginable - a strong left movement in the rich world - not strong enough to win a revolution, but strong enough force major concessions from capitalism. So one last question and I'll leave you alone on the subject; is it simply that you can't imagine that the techical obstacles are as trivial as I'm saying, or that the concessions I mentioned seem so threatening to capital (to you) that you cannot imagine them ever being made under capital - that only a socialist revolution could carry them out - a strong left unable to win a successful revolution would (to you) be uable to extract these as concessions even from a weakened capitalist class that was still in charge.
