With energy water is not a problem. Civilization followed the water early on because it was a source of energy (food was the first source of energy btw) Civilization has always followed energy, and I can show that to you in pretty much any period of history you care to point at.
The cleanest streams in California are not high in the Sierras, they come out of the outflow pipes of some of the sewage treatment plants. It takes high energy to make that water nearly atomically pure. With energy desalination is not a problem.

Sadly, I must disagree. Many millions of people have ephemeral water supplies, and for them, it is death.

Climate change means more displacement. Given the governments in those most vulnerable areas, you know, in your heart of hearts, what this means.
