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 either direction I'd probably say "that's the real reason I moved" or "can't believe they're waiting my tax money on this", but I'm not, I'm just a guy who likes hedging his bets. The nuclear is especially nice because cheap electricity is the true backbone of society, and we've seen the market prices go straight up _negative_ a few times due to overproduction.
Self recommending! Come to Finland and help us build a stronger democracy, whatever that means to you.
Takes surprisingly little to collapse a civilisation when you kick its knees out from under it.
Northern Europe should worry about the Gulf Stream or Atlantic Conveyor currents failing and changing the climate.
Another big one is melting permafrost. Warmer temps cause permafrost to melt and release CO2, which leads to more warming, and repeat.
Finally, there is danger of ice sheets melting which could rise sea levels by hundreds of feet.
