How would you enforce it internationally though?

That's the magic thing about a carbon tax & tariff -- you don't need to.

The tariff for cooperating countries is 0%. The tariff for non cooperating countries is set appropriately for the estimated carbon content of the import or higher.

"Fix" the problem, like, sate the core tax-motivation behind most top-down domestic political issue incitement? How? Via a rigidly capped tax?

Or would it be a beginning tax that is mere precedent and has a de facto uncapped potential? In order to allow limitless and much easier siphoning of production value by those who control the tax.

Can the tax go to 99% to take us back to the stone age? Can the tax be abused against powerful political enemies who derive their incomes from industry?

As an adult you can't possibly believe that taxes, let alone punitive taxes like this proposal, are implemented to solve problems. There's nothing "brave" about voting to move money from the coffers of others to one's own. But as governments become more broke, do expect to see more agitation in favor of such taxes.

Tell me about your problems, and maybe I'll even get on board to help solve them. But end up at a final act of utilizing taxation to "solve the problem" and I then know that you are running a mafia hustle and were the entire time.

Nordhaus won a nobel memorial prize in economics for this proposal.

Carbon taxes are supposed to be revenue neutral. Handed out as a fixed dividend to all citizens. That way it becomes a wealth transfer from high carbon emitters to low carbon emitters but doesn't fund the government.
