Quote from: REAt some point in that timeline there will be a global food shortage, and the poorest countries which are food importers will take the biggest hit.
Those poorest countries are poor because they are exploited by the rich countries. That's kinda why the latter are rich in the first place. They can't feed themselves because they aren't allowed to. Tropical lands are inherently more productive than temperate (where the rich countries are) because they can produce all year instead of only in summer/autumn. They can also produce a lot of things we can not. We do produce more grain per hectare, but only because we subsidize our extremely inefficient agriculture at their expense. And that includes vastly higher fossil fuel inputs produced by - or domestic production thereof indirectly enabled by other things produced by - guess hoo.
It's not just food of course. Minerals, hydrocarbons, finished goods and the forcibly expropriated surplus labor needed to produce all of the above. Like, I know there's this notion that the third world people will "sadly" die off and "we" will wall ourselves off in our impenetrable climate fortress but uhhh nope. This is a global system undergoing a global crisis leading up to a global collapse. Doesn't mean everything will collapse simultaneously. Still... we shouldn't expect ourselves to be in a position where we watch and talk about those poor browns dying "over there" and then move on with our mostly intact lives. More likely is... by that stage there will be no "we" as pertains to the current geopolitical order and whatever "we" actually exists shall be powerless to use and abuse and fiddle with the lives of those folks over there as we do now. If they decide to come here and "we" want to stop them, good luck.
