There are a couple of ideas for engineering that would make the albedo (reflectivity) of the North Pole area controllable. One involves a space shield, the other is floating panels (one side black, one side white). The larger issue is a) predicting the result and b) the 'it could be good for Ontario' problem that all types of climate change bring benefits as well as costs. f.ex. a return to glacial conditions would suck for the Northern Hemisphere, but be good news for India, Africa etc.
