buy some land in Iceland or Norway, everyone will be migrating that direction.

Change will be much more brutal closer to poles; average increase of temperature of 3 C in the world means more like 7 C increase at polar regions themselves. Moving into tropics might be easier in total, just make sure to grab high ground.

do you have any evidence for this assumption. Yet I havn't found any article about what will happen where and where to raise kids in the future with water and moderat "wether-disasters". Are there any papers out to read?

that question is one i haven't seen an answer for. maybe there isn't one.

if there will be a good place to live in 30-50 years, it won't be easy to get to, since the current (at the time) dwellers and its infrastructure won't be able to cope with 100x population increase in ~10 years and the whole thing will end in immigration camps as we see now in southern europe, just much bigger.

It's not like they'll keep their forests any better though. Worse, in the boreal areas.

Iceland does not have many forests in the first place due to historical deforestation and free reign of sheep.

Poland, Belarussia. The same circulation that is sucking hot air to Western Europe is bringing back cool air to Eastern Europe.

We have cool July - evenings are so chilly that I have taken out electric blanket and dove vest. 5-8 deg C at night.
