Just a reminder that when I started calculating this based on climate maps, I was thinking not only about GW but also PO. Obviously anyplace COLD gets you out of GW, but if it makes you burn more fossil fuels for heat – your own, or your electric plant’s – it’s counterproductive. Hence, Bay Area winters – on the wetter, cooler side – aren’t too chilly, and summers aren’t too hot for now, but this “sweet spot” will drift north over the generations.
Food can also be grown there in abundance, but then it’d compete with living space, employment space, etc.
Keep in mind that areas around this area, while not as ideal, will be better than many. There are other less-ideal spots around the world comparable to areas abutting this part of the Bay Area. If I think about it, I may look into listing them.
Another lifestyle to consider is Snowbirding, ie, spending winters closer to the Equator, and summers farther away from it – water resources being equal, of course. Jobs would have to migrate, too; I’m not sure exactly how you work that out. What about two half-year jobs instead of one full-year job, with year-to-year guarantees/contracts of employment?
