yes the north pole is mostly floating the south pole isn't, from my quick search if the north pole completely melts its already being displaced so nothing changes, if the whole of the south melts, we get a water rise of about 200 feet. if the south pole melts ill be under water i think.
its a tiny bit confusing, but here it is, north pole 10% south pole 90%, i'm not actually even sure which one is melting the most i haven't looked it up in all fairness.
