Could this save Canada, too?

Cleaner Air Means a Warmer Europe
Essentially pollution in the air kept Europe colder and now that they are green freaks over there the sooty particulates reflecting the sun back are gone and the place is warming up. I guess we could take this to Canada and clean up the air here and then the northern hemisphere would warm up, too.
Will this contradiction ever end? I thought algore said the debate was over.
