Granted, we really haven't seen that much of spherus magna. The convention is that the northern and southernmost point on a planet are the coldest locations on a planet, as they have less direct exposure to the sun and Bones will probably explain it a lot better latter on.To the point: we have had no indication that spherus magna has frozen polar caps. Why? Do they even exist? Could their apparent absence have something to do with fact that the planet is part of a binary star system, the planets sheer (estimated) size, or that two giant chunks were ripped away for 100,000 years where the poles would have been, but even then.So did they exist. If not, why?
