it'd be nice to have some idea of where might be a good place to move to, if this is as inevitable as it sounds.

Not as nice as you think. You could dodge harsher winters, an energy crunch and crop failures, just to move to somewhere with heatstress, drought and cropfailures.

We must not view climate as the thing to watch. It's one part of a larger complex system of systems. Changes in the AMOC can trigger changes elsewhere, and more importantly, elsewhere is changing on its own too. Not just because of emissions.

It's a lot to digest, especially if you don't have a background in ecology, biology, environmental sciences or systems theory. But a solid easy framework is planetary boundaries.

It's all 9 boundaries together (plus any new ones discovered) that's going to pickle us. We are exceeding 7 of the 9 identified so far and there are and will be severe consequences for having exceeded our planet's limits.

I worry about climate change A LOT. I worry about Ecological Overshoot and Collapse due to Planetary Boundaries even more.

There was a documentary about it made once I think it was called The Day After Tomorrow.

I doubt anywhere would be a 'good' place to move to in this scenario. Maybe there would be better places than (southern?) Europe, but things will still be tough even before you factor in everyone moving to exactly those places and the fact that food will become scarcer globally. My recommendation is avoid having children at all costs - they will have to live through this.

The country projected to profit the most from climate change is Russia.
