The four examples today show Yakutat (Fig. 1) which is near Glacier Bay, Alaska, and San Francisco (Fig. 2), both on the west coast of the U.S.eh?, and both covered in previous posts (Proof of Concept - 3).
These four quickie graphs I did show the contrast of global mean sea level (GMSL) and global mean surface temperatures (GMST) with real local historical sea levels.
The use of GMSL and GMST, as these graphs show, does little to inform the public of the radical volatility of sea level in local areas.

The global mean average is a mathematical tool, but is not a proper way of informing the public because it covers up reality whether intended or not.
Anyway, when one asks the question "why is a town on the west coast experiencing

Journalists near one of those locations seem to have no clue as to why serious sea level volatility is taking place, reporting the issue as if it is the new normal, or as if the land has risen 4 ft. recently instead of taking thousands or millions of years (Alaska Dispatch News).
I guess the unknown is the new global mean normal, as cities even closer together than San Francisco and Yakutat (Juneau and Prince Rupert - 400 miles) tell the same tide gauge station story (see Fig. 3 and Fig. 4; cf. The Gravity of Sea Level Change).
