Global world product is, say, $75T per year. Global carbon emissions are, say, 10B tonnes per year. At $100 to extract a tonne of carbon, that's $1T per year to get to zero emissions. i.e. at a tax of just 1.3% of global GDP, we could extract ourselves from the shit. This seems cheap at the price. It would cost a lot more to fight any decent war. Yet like the proverbial frog in the boiling water, we'll most likely sit here as things heat up, not taking action because it all seems too hard or not yet an urgent problem.
