As a species, we seem to be in a period of considerable uncertainty, where familiar features of the political landscape are disappearing, and it is not clear what will replace them.

How much of the planet will be underwater or uninhabitable due to climate change, and how many millions of people will be seeking refuge from war, crime, oppression, corruption, or environmental degradation? Are the dysfunctions afflicting many wealthy democracies a momentary blip or the beginning of a slide into dictatorship?
