For example, the ice cover in Greenland is melting at a record rate. If it goes completely, this alone would raise the sea level with something like 7 m (23 ft).
If everything goes, it will be something like a 65 m (213 ft) sea level rise.
Now, given the sluggishness of action-taking in this matter, some of the ice cover will almost certainly melt before anything gets done.
The end result will probably be much more than a few feet, but less than the maximum, so let's guess 30 m (100 ft).
Now, I suppose some self-correcting actions are automatically taken when enough people get displaced and pour to dry areas: traffic ceases in the coastal cities, air traffic to these areas will cease as well, factories will stop, and so on.
But still... given +30 m, have you already checked where the current coastline would be where you live?
So far you need the global integrate of all changes.
I would guess that the parts of Alaska that are seeing the sea level fall are due to the land rising from tectonic activity.
Things like changes in water temp and currents can also play a role.
