Easy.
Newport Tide Gauge 1930-now 2.74mm/yr (11cm or so in 40 years)
If you play games with statistics you can get a slightly higher trend the last 25 years, which would roughly match the satellite altimeter record of 3.3 mm/yr since 1993.
Doesn't sound like much, but much higher than the century(s) before, which was 1.2-1.7 mm/yr (estimates vary). There are many areas flooding now on spring high tides that didn't a decade ago; in many cases we build that close to the shoreline, that small changes in SL have big implications.
Scarier when you look at where the 3.3 mm/yr and the older tide gauges (globally) fit on curves modeling SL rise; we are on the higher side of things, and this includes models made independent of the data collected the last 20 years.
However high it ultimately goes in this century and beyond, we know it is rising, which means no matter what, things ain't getting better along the coastline.
In this forum, I am usually talking out of my ass . On this topic I know a thing or two for a change
