The reasoning is sound. When the last dice are thrown the ones who have amassed the most wealth do have the best odds of survival. They'll be the ones with the power to secure food, clean water and private militias. If they can delay it enough maybe they'd have all puttered off to Mars by then.
I can't help but think this is how the minds of those at COP28 work. Short-sighted grifters standing around trying to maximize their share of the remaining crumbs before sticking us with the bill.
