Actually, global warming could make scandinavia ever colder. The reason scandinavia is this warm is the golf stream, which brings in warm water masses from south. It's kept alive by two "motors", one in the southern end and one in the northern. When the stream reaches north pole, the ice cools it down and the cold water travels back south in the bottom layer of the atlantic sea.
If the climate gets warmer and the polar ice starts to melt, the cooling process will eventually slow down, thus decreasing the flow of warm water as the backstream weakens. This will make the golf stream either stop or change course. (something like that, I don't remember the link to the article...) Ofcourse, as the golf stream slows down, the polar regions will get (maybe) colder again, maybe increasing the downstream but restarting the golf stream will take ages and if it alters course, it might never come back.
This is just a theory among the others and it's hard to proof, but still the effects on global warming might not give us palm trees and hot summers, but the opposite.

..nevermind, I really can't be bothered..
