Maybe people take it not serious when I ask above about a tectonic tilt, due to the melt down of the polar ice.
On the web
here I found this:

Tectonic Tilt Rates Derived from Lake-Level Measurements, Salton Sea, California
MARK E. WILSON 1 and SPENCER H. WOOD 2

Tectonic tilt at the Salton Sea was calculated by differencing lake-level measurements from two points on the sea. During the past 26 years, tilting was down toward the southeast. By 1970 differential vertical movement amounted to 110 millimeters between two gages situated 38 kilometers apart on the southwest shore. A reversal in tilt direction in late 1972 has diminished the net differential vertical movement to 60 millimeters.

Now, here you see tectonic tilt is not something coming from an imagination running wild.
In the article the tilt is very little.
But on the northpole ice caps run into the billions of tons. Lifting, or removing the ice must surely cause some tilting, or not?
So then some parts would be lifted and other parts would sink, so also water is displaced, etc...
