It seems to me changing equilibria is precisely what allows the world to run more smoothly! Businesses coming and going, migrants moving from static societies to more prosperous ones, scientific revolutions overturning old ones, etc. I'm not saying that change doesn't cause any local instability, but the world very frequently net improves from change when its long-term benefits outweigh its short-term costs. It's not clear to me that several million square miles of land suddenly becoming more habitable wouldn't provide a better economic arrangement for the world 100 years from now, even when you net out the costs of people having to migrate to new areas.
