Yeah, the “winners/losers” things is pretty much just based on physical, relatively easy-to-model stuff, and fails to include the more speculative sociological stuff.
Hey, Mr. Montana ranch owner, your scrubland will become much more fertile if the moderate predictions about climate change come true.
Ooh, that sounds pretty good.
It’ll become wetter, and more temperate, and you’ll be able to grow several crops on the land each season.
Yeah, that’s really good.
And because a large chunk of the great plains will become desert, your land will become the new breadbasket of North America.
Wow, I’m gonna be rich!
And of course since the previous breadbasket will be wasteland, the food grown on your land will be all the more valuable.
REALLY rich!
Actually, large swaths of central and southern North America will be effectively uninhabitable.
Oh. Man, I honestly feel bad for those poor people.
Most of those people will still be alive.
That’s good.
Just homeless and starving.
Bummer.
And well-armed. And looking for a new place to live and for food.
Um…
Really, they’ll have no choice but to move north.
Good thing I pay my taxes! The government will make sure law and order prevails.
There’s very little chance that the US government will survive the mass-migrations and starvation in any form that you recognize.
I be rich though. The rich people always land on their feet.
Yeah, sure.
