Rising sea levels are going to mess with the internet

Its not satellite data,  it's the exact same data-set that NOAA provides for ocean levels; The data is from tidal sensors;  the data is relayed via satellite so... technically ;). It's kind of funny the data in the table,  vs the chart-data presented,  some .orgs say 80mm, some say 60mm all depends on when you start counting. I'd like to see the raw data,  geospatially portray it,  and get a sense of the true impact;  an average of a statisticcal averages, smoothed and corrected over 60 days with a self-ratcheting baseline... Not sure how valuable the data here is other than support a presupposition.

Well, you must not *really* want to understand, since there's a "Learn
more" link to follow on the above page that (after a couple more clicks)
would lead you to this page that has some explanation:
