So decrepit you have noticed no increase in sea level but their data takes precedence over your observation - interesting.
You seem to be concerned that their claimed data increase in sea level means we have a climate emergency regarding a rise in sea level.
I do not know a single person in Perth who has noticed any increase in sea level yet we need to take all these measures to reduce our carbon footprint to stop the impending catastrophic increase in sea level.
Sounds like something from the W.E.F.
"During their search for historical sea-level references, the Bermuda Archives uncovered a high-quality military photograph taken in 1870 of buildings in the Royal Naval Dockyard, on the western tip of Bermuda. Captured in the photograph was the sheltered, south-facing dock wall, still in existence today due in part to its construction from blocks of dense Bermuda limestone, as well as decades of historical preservation efforts.
While the tide level at the time of the photograph was unknown, the team noticed a solid black line running the length of the dock wall, parallel to both the surface of the water and the top of the wall. Known as the "black-zone," (or the "coastal scum line" as Rouja calls it) this stable community of cyanobacteria thrives in a very specific location: just above the mean high-water mark.
A visit to Dockyard in 2007, the year the photograph was found, revealed the wall was still very much intact, along with the black-zone line running the length of it. "However, we quickly noted that there was one significant difference: the black-zone sat approximately one full block higher than it did in the 1870 photograph,"
