The ice sheets on Greenland and Antarctica have enough mass to attract water to them, meaning sea level is exaggerated by being higher than it should when there are ice sheets there. So, the ice melts, the mass is redistributed, and sea level drops.

On top of that, the mass weighs down Greenland and Antarctica, so the continents will isostatically rebound as the ice is shed off, causing uplift and further sea level drop.

That mass has to go somewhere too, so as it enters the ocean basins it will weigh them down. This causes the basins to deepen and dampens the effect of sea level change, resulting in lower than average rises in some areas but continued sea level drop near the ice sheets.

So yea, differential sea level change.
interesting, thx

Indeed!
Hey, dude! I've got this fantabulous piece of seaside real estate with your name on it just waiting for you! Built to specs by one 'Donald X'. And you won't believe the low-low price (he needs the money quick for the funeral of his wig-in-law)! Come see me when you're in town and I'll fix you up real good, bro!
