Say the worst predictions come true...a 4C or so rise in global mean temperatures by 2100 or so. By then, do you think much of the South will just become almost intolerable to live in? I dread what a place like Phoenix or Dallas would be like to live in. Even with A/C, people will still want to be out and not locked indoors all the time, what if Phoenix regularly gets 120F+ summer days? I wonder if this will see a revival of the Rust Belt of the Great Lakes, as well. Also, if sea levels rise and many coastal areas have to be evacuated (unless they build dykes or find other ways of keeping the sea at bay) do you think many will leave the coastal cities and go inland?

I think that there will always be upward migration, just because it suits some people better. However, I have seen way more North to South migration.

Of these migrations, I've seen voluntary moves like:
- natives of Miami moving to suburbs of NYC (they were Jewish and the Dad was a CPA, so better opportunities)
- natives of SoCal moving to SEA, PDX, or even inland, to Boise or Denver
- natives of Texas (smaller, more inland cities) move slightly northward to places like Kansas City
- people are discovering they like Pittsburgh or inland New England/mountainous upstate NY and are moving there

Heck, if I could live the way I wanted, had no relatives nearby, and could get in to Canada, I'd move to Montreal. I don't get on the plane to come home too happily when I go.

It's possible. Phoenix already has a huge urban heat island affect that dissipates most summer storms from getting to downtown. If the city gets any hotter we might lose a few thousand Californians and a few hundred thousand mid-westerners.

dwarfed by international migration - if those temps are bad in phoenix or houston, imagine what they are like in places where AC, etc are not so relatively affordable. Plus where agriculture may be collapsing, etc.

Yeah I think so ... Phoenix is already intolerably hot, it will be totally unlivable if global warming is that bad.

If the worst predictions come true then the landscape of our country would be completly different because of rising sea levals. All of the cities near water, such as in the Northeast, would be underwater.

Cities that would thrive would be places like Denver, Saltlake city, Boise, ect.. I think the piedmont region of the south (Atlanta, Charlotte, Birmingham ect..) would do fine because they are high enough to not flood and would have a new way of cooling off being mutch closer to the beach.

The predictions are for the oceans to rise 1-3 feet....not 1000. It will sink SOME cities but not all coastal cities.

Global Warming does not necessarily mean "warming", it's climate change in either direction.

Cities along the coast will have massive levee systems just like New Orleans now does. New Orleans will be about the same as it is now, it's already 20 feet below sea level, what's another 3 feet. Miami will become like New Orleans is now.

I think the heat will negatively affect the north worse than the south. I read that Chicago's climate will become more similar to Baton Rouge's in coming years. If Baton Rouge's becomes like Cancun's I don't think that is as much of a difference as Chicago having a subtropical climate like Baton Rouge. A large part of Chicago still doesn't have A/C and is unequipped for the heat. The difference to people in Baton Rouge is they'll probably be able to leave the pool open all year in the new climate model. In Chicago they'll have to thin their blood out a bit if they want to survive.
