> There’s nowhere near enough fertile soil in former permafrost.

Not only that, former permafrost is highly unstable almost by definition: as soon as it starts melting it starts shifting. This is already starting to be an infrastructure issue, as roads and bridges built on/in permafrost degrade at very high rate when it thaws.

And that's before considering the cool methane bombs. Nothing says stability like your field or house being replaced by a 40m deep crater.

And then, obviously, global warming / permafrost melting doesn't magick a more reasonable insolation. Even ignoring soil quality factors, agricultural yields start degrading as you go further towards the poles because the seasons and sheer amount of sun are crap.
