Make Siberia more livable by building a shit ton of dams in the mountains, creating a vast amount of lakes. I don't know if this will actually do anything. But maybe a lake effect will change the Siberian Highs that causes massive cold weather patterns to hold in the area and it's surroundings? Was an idea to maybe make Vladivostok and the Russian Far East more like Seattle weather wise. More rain, more movement of air generally, lots of fresh water stocked up, maybe routed to central Asia. Idk what would actually happen but it'd be fun to see
