USA-centric views follow:
Move to the Michigan Upper Peninsula while the bridge is still there.
Personally I'm hoping Michigan can build a wall along its southern border to keep the riff raff out.
That's a joke.
I really want a deep trench or moat instead.
More seriously, rental folks are screwed. Very few landlords are going to improve insulation and air conditioning, they'll try to dump the property on the next sucker instead. And by the time any meaningful legislation is passed, everyone will have moved as far north as they can.
Regarding Michigan, I wonder if states will try to suck the great lakes dry during this century? Would former US states go to war with each other over water? 100% they will.
