I really don't think there will be a WW3.
If there IS a WW3....it will be one of the following situations:
a) Nations worldwide invade the frozen north, AND Canada AND the antarctic over freshwater/snow to turn into freshwater. (not likely to happen in my lifetime, if at all)
b) Someone manages to fire a nuke at the US/China/Russia/North Korea. The target country's systems will take over and fire nukes back. Soon EVERYBODY is slinging nukes. And then, hey presto, the world is now a radioactive husk, and almost everyone is dead as DogMeat. :s
