What about the very remote villages in the colder/harsher parts of the world? Ie the disputed islands north of Japan, the easternmost parts of Russia, the vast northern parts of Canada, etc? Figuring a way to make those worthy/capable of growth to cities seems still lower lying fruit than Antarctica.

That stage of humanity probably needs to have a stronger sense of community than current, too.
