The whole scenario is far fetched. We're imagining some egalitarian world (won't happen), in which with today's technology we need to make due with tomorrows resources, but without time to adapt and find alternatives.

More realistically, we need to start making at least some steps. If air travel becomes more expensive, we'll do less of it, and at least try to find alternatives, personally. Society might try to find workarounds, like negative emissions, or construct alternatives (like high-speed rail) that are "good enough", at least for many flights. We might have alternative, emissions free fuel, someday.

But the real point is: this is not going to be as extreme as is sketched simply because inequality isn't going away, and secondly - this is necessarily going to happen gradually, so the impact will be reduced as society will have time to adapt. Let's just hope gradually doesn't mean glacially, because then we'll pay the climate price.

That depends on what you mean by "gradually". Climate is a non-linear system. It can change radically in a very small number of years. Within a single generation, for example, much of the world's current farmland could become desert. That is going to be very hard to adapt to.

If that comes to pass I hope I won't be alive to see it, but I think 'hard to adapt to' is putting it very mildly. You're talking about war and famine on a scale that the world has not seen before.

[lisper]

Yes. That's exactly right. I think even the people who worry about climate change don't fully appreciate how grim the situation is, and how fast things are going to get really, really bad, a small number of decades tops. If you haven't already, look up "blue ocean event."
