The idea that the world would ever actually remake itself in order to stop the warming was always an illusion.
Various groups were glad to get together and assemble plans whereby others would pay the price of implementing it, and lots of people were happy to go along on the theory that it wouldn’t hurt them personally. All this happened during a period of significant (though largely illusory) global prosperity.
With the economy crashed or crashing, the notion that any democratic polity will implement these plans is just idiotic. They may agree to and try to get others to, but no countries will actually implement them at the cost of their own people.
The global warming policies the radicals dream about could only ever be implemented by a global totalitarian government.
A global tyranny is exactly what they want, and any excuse will suffice. They have to set up the kingdom of the Antichrist somehow, don’t they?
