For what its worth, I also wonder about that. I live in Canada, and I'm not aware of what steps are being taken to understand how we would have to respond to growing areas moving north. I've read that the areas where favourable climatic conditions are projected to settle in that we only have sufficient top soil for a few decades of intensive agriculture. I wonder what steps are being taken to deal with that.

I also would point out that people are upset that change is happening because they look at the form the change is projected to take, and most of the forms of change involve a lot of people either dying, or just having shitty shitty lives.
