Then, when the ice builds up on Baffin Island (which is where the big glaciers form that surge down to the Great Lakes) we can round all these guys up and prepare them as a suitible sacrifice to the "ICE GODS". Then we light some really big fires, burn a lot of coal in the least efficient manner, and demand nukes.
When I was a kid I remember the Russians thinking about arial dusting of the ice fields with carbon black to warm things up.
