I think, looking for spots where "climate there will be stable" is limiting, because some spots will actually benefit from the local climate change.

I would also see it as a two-level model. On the global scale, everybody will be negatively affected by the climate change, because its consequences (drought, flooding, but also refuges) will destroy economic cooperation and productivity, so everything will be hard to get and more expensive, and people will be looking for any job.

On the local scale, some land that was cheap and uncomfortable to live before might become wanted and better suitable to live. I think, the places that are barren and/or too cold today might benefit.
