Okay, in light of your gloom and doom take, what’s the solution?
I don’t do gloom and doom. I do numbers.
If they are what they say they are, why do you think there has to be a solution?
But . . . if you must have one, the answer is reduce consumption, and that need not be uniformly globally. Most likely the way that plays out is by reducing the war’s loser’s population 100s of millions of billions of people.
That would buy some more time. But eventually . . . well, there is a fundamental truth — The Easy Oil Is Gone. A step back in technology via war and you don’t get less extracted from the ground. You get zero. There will still be some down there, but it’s not easy and lower tech can only do easy.
So . . . extinction is possible.
