I don't know how they even measure such a minute change. I mean they must need reference to compare against a stable point in space. What is that reference and what point of city you compare against that stable reference?

They measured nothing at all. That's how.

This is simply their calculation.

And it's absolutely possible to measure this, see: https://www.thoughtco.com/measuring-plate-motion-1441107 and https://www.youtube.com/watch?v=S1m1tAGbfL4

They don't even question that it is sinking. They take that as granted -- sinking 1-2mm according to "sattelite" data. Then they spend the study demonstrating why this is attributable to the weight of the buildings they estimated.

Its magnitude is roughly about one quarter of the low end predictions for sea level rise, yeah. Not much, but worth factoring in.

A child born today, will see New York City about 6 inches lower by the end of his full natural life.

Yea its peanuts.

Not as quickly as your politicians are.
