The locations where the cooling has been seen are at the south pole research station which is really far away from the oceans the suggested reasons for seeing this cooling are many and complex but in the end inconclusive. However the Antarctic Peninsula and western Antarctica have warmed and since records begun and measurements began there about 80 years ago the average temperatures are higher and the ocean has warmed significantly.
However to your point, the Arctic cap melting would not add to sea level rise, but all that cold fresh water entering the North Atlantic could put the gulfstream at risk and if that happened, we'd know all about it.
