  •  Hmm, OK.... (0+ / 0-)

    The central part of Canada got scraped down into the US midwest, but I wonder about other parts, and about the northern parts of what used to be the USSR.

    •  you need to take the soil into account (5+ / 0-)

      that´s where the otherwise seemingly logical idea that agriculture moves to canada or siberia, fails. Where it is today, agriculture is sustained by soils that have grwon in their appropriate climate zones over timescales of thousands of years. Thats the times necessary to build such a thing. When a permafrost melts becuase a different climate zone moves over it, then it doesnt yield arable land as soon as its thawed. To the contrary such land would be a quasi regolith, on which successive waves of vegetation would have to work for a long time to create anything remotely similar to the postglacial black soils of the Ukraine for example. Thta means, yes, after a long wait those newly warmed lands could take over the breadbasket role of the southern lands - not before.

      thats whats meant with teh "quality" of the land. It has none to start with, it first would have to build some, and that could take easily tens of generations, time thats not available if we need to replace some breadbasket quickly.

      the speed of climate change makes it so deadly.

      •  yes, and yes. though, compost. (0+ / 0-)

        Municipal organic wastes e.g. "food and yard waste" can be composted relatively quickly, and could be shipped in large quantities to till into the soil. Add manures (cow, horse, chicken), add biochar, add a few other things, and one can produce something like a viable soil fairly quickly.

        However all of that still lags behind the speed of climate change, and the economic cost of doing it will slow it down further.

        Bottom line: lots of starving people in Africa and Asia, and the emergence of chronic hunger but not quite starvation as a recognized social problem in Europe and the US. And then it only takes a few very pissed off people with access to the internet and a highschool-level chem/bio lab, to whip up a revenge-plague and unleash it by suicide carriers. Mark my words.
