Sad that you have no choice but to go.

If you're still trying to figure out where in the US might work out for you, have a look at Colin Woodard's "American Nations" (he's here on Medium, https://medium.com/@colin_woodard )

To condense a lot of his book's premise, the original colonies along the Atlantic coast were very different - and those differences carried on into the rest of the US - so you get a general idea of the kinds of communities in which areas. Then cross-reference that with the now-nearly-unavoidable climate disasters coming - and pick a place that you and your eventual kids and grandkids can flourish.

I've seen a couple of comments about western Massachusetts and the finger lakes region in upper state New York. Both are part of a 'nation' a lot like California - minus the "my own liberty first" strain that comes from the West, got melded in where you are.

Personally, I live in a western exurb of Boston - but real estate here has gotten absurdly expensive. Every year that expensive area moves a bit further West. If I invested in real estate (I don't) I'd think about the Fitchburg-west region, as it'll likely go there next - particularly as there's a commuter train that runs Fitchburg-Boston, and there are plenty of tech and creative jobs in Boston/Cambridge.

But the important part is that you find a place that's good for you. Best of luck.
