Yeah California is far from the climate hell folks from back east think it is.
And I speak as someone who has to literally watch the megafires burn ever closer to my childhood home.
Y'all in the South may be doomed, but trust me - California is rich, connected to the rest of the world, and full of immigrants. Washington too. Oregon is too inept to do anything but where they go, even if we eventually lose our crazy rurals east of the mountains to Idaho.
Secure your future by getting to a place capable of adapting. It's the American South and Midwest, islands around the globe, and South Asia that are going to get smashed hardest and soonest over the coming years.
Go where the money is. That is what people have always done.
