Don't kid yourself. The north pole will just be an incredibly boring bed of dead water like any other ocean by then and Antarctica will likely be just a bunch of rocks, possibly leaking gas that was trapped under ice for millions of years. At least there will be some nature in scandinavia to look at through a big window in an air conditioned cruise ship.

Well yeah, there might be some exceptions. But in a 4° world, economic collapse is very likely, and tourism would be one of the first industries to die out. Antarctica has no soil to speak of, so not exactly a good place to settle. The most northerly lands will indeed be interesting to settle in at some point, though I wonder how long the adjustment period would be (e.g. as long as the permafrost is melting, the ground will be unstable)
