The problem is fixable, but my biggest worry right now is that rich nations will do enough to save rich nations. They'll get most of their power from non-carbon based sources, pollute significantly less from industrial processes, protect their agricultural output, and switch 90% of cars on the road to BEVs. Then they just deal with the problems of increased flooding, wildfires, etc.

Meanwhile, the Middle East turns into a power vacuum because nobody wants their major export anymore. Africa starves to a level not seen in decades, or maybe ever.
