It also glosses over that arctic land isn’t usable for agriculture. There’s nowhere near enough fertile soil in former permafrost. The areas that did have fertile soil are now deserts or covered in salt water. It really comes off as disingenuous to me in that regard; it’s a quantitative analysis without any of the qualitative measures that are necessary. |

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.
