The problem here is that the presence of ice as a coolant ensures that the temperature is always around the freezing point.
If the ice is gone there's nothing to clamp that temperature to any specific value and it can rise as it wants.

Incidentally, this is why average sea temperature is a very poor indicator for heat added to the ocean due to the cooling to a nearly fixed temperature which happens at the start of it's cycle. For a good indicator you need to looks at how much ice is melted, since that's where the energy is going at the moment.
