2 degree increase up in Canada might be appreciated even though they aren't building pyramids. 
You've mentioned the potential benefits of increases in temperature in Canada before, albeit maybe in jest. You realize that it might be accompanied by turning Iowa into a desert. Would that be ok?
Funny how we've gone from man-induced climate being impossible, if not a hoax, to now wondering if climate change might be a good thing. Seems irresponsible to not also consider that it might also be a bad thing. Shouldn't you want to study that a bit more before making any assumptions either way?
