@cstross @tokensane @tuban_muzuru So we're going to have (should we pull this off) a bunch of layers; local solar PV, local storage, some amount of grid, some amount of shippable fuels, and lots of remote production of shippable fuels and energy-intensive goods like aluminium. The remote production gets pushed into mobile forms by sea-level rise; coastal infrastructure with an unpredictable lifetime mostly doesn't get built.
None of it matters a jot if the food problem doesn't get solved.
