Gravity means oceans are attracted to the icecaps. When icecaps melt, the level around them could even lower! and Europe might not even see much raise, because the natural equilibrium of oceans without icecaps is to have higher levels than today nearer to the equator. So I’m barely surprised with a 70m estimate due to gravity effects.
