I never worried particularly much about climate change, but just to hedge my bets for my kids I moved to northern Europe. For the most part it's just equated to milder (= bearable) Winters and nicer summers up here. I guess we also spend a fair bit on moving to renewables up here - Finland achieved energy self sufficiency last year thanks to a good combination of nuclear + solar + hydro. If I were an ideologue in eit…
Similar, though leaving the US had a lot to do with hedging our bets against a crumbling democracy as well. How is Finland? It was on our list but we wanted to have good train connections to the continent so ended up in the Netherlands (but above sea level). Oulu has impressive winter cycling though.
Also - I can't imagine North Europe will remain prosperous if America somehow fails, the West is very much dependent on the U.S (now also for energy). But I do hope you enjoy your time, I lived in Leiden for almost 4 years and it was like living in a postcard. Shit weather though.
