I wonder why, if the climate hysterics are to be taken so seriously, nobody’s talking about colonizing Antarctica (not to mention the barely populated Arctic and sub-Arctic regions as well). An entire continent with almost nobody on it, yet the temperate and tropical parts of the world are bursting at the seams. There’s obviously plenty of water, soon to be melting . . .
I skied there.
One problem it has, it's miserably, unremittingly cold, even during the months it spends in 24 hour sunshine. Geothermal energy (from at least one volcano) might make a city-sized settlement pretty comfortably warm, and well-lit (from the electrical generation). But you'd want to have a backup plan (like a giant coal-burning pwer plant and six to eight months of coal supply, since delivery of coal would be impractical for a good chunk of the year), and there'd be no economic life for the place, unless Amazon opened a headquarters there. Maybe sell units to pensioners...
