How do you fix Global Cooling? Well, obviously: you build lots of very productive and dirty factories to produce cheap goods for export. The same would go for the Scandinavian states, and Greenland, and so on.
Warming the Planet on Purpose
I'm surprised it took so long for the Russians, crafty as they usually are, to figure this equation out: if global warming is said to be a problem for most countries, it's not for Russia. Global warming might turn Russia into a pleasant and mild place. If anything, Global Cooling is their concern. I hope Putin and the Russian leadership push this really hard; it might eventually force the moment to its crisis: what would Americans do if, while they were losing jobs and saving the planet, the Russians threw together a dynamic smoke-stack economy employing millions and overtaking the U.S. as chief economic power in the world? [unlikely, I suppose; but neat!]
