Yes yes the solution here is to physically move hundreds or thousands of years of capital investment, especially forms of capital investment that cannot be moved and are just abandoned/destroyed.

That way we can emit a bunch more to rebuild that already-built infrastructure in a different locale!

You're forgetting that the rebuild is only for survivors so it's a smaller scale.

There's a lot of time though. It's more a matter of the kids or grandkids moving somewhere colder rather than anything sudden. And the biggest problem with building a new house up north is getting planning permission. The actual construction can be relatively trivial.

It's somewhat ironic all the billionaires are about space and mars and shit - like, ok, super in-hospitable, go for it. While we should be building our space fortresses and geo domes on earth to keep the elements out, and survive on some kind of lab food.

Maybe the new cities could be built to be walkable.

Unfortunately, humanity repeats itself.

This time it won’t because there aint any fuel left.

That would be a cool story plot: starting civilization again with all the knowledge but none of the fossil fuel power. Solarpunk?

I think you overestimate how much knowledge there will be left.

Of course not all the knowledge will be left but enough to easily build basic engines using Stirling or Carnot cycles or even pressurized steam. Solar panels don't have to be 25% efficient, 5% amorphous silicon cells would also be very useful.

the little domed areas we will call cities will be walkable. so there's that!
