Expected by whom? According to NOAA records, there has been no change in sea level in San Diego for 30 years. Same for La Jolla. Same for Los Angeles. Same for Santa Monica. Same for Santa Barbara. Port San Luis has never seen any sea level change. Monterey hasn’t seen any change for 30 years. Same for San Francisco. Alameda has never seen any change in sea level. Point Reyes has never seen any change in sea level.Port Chicago has not seen any change for 30 years. North Spit may have gone up a few millimetres, and Crescent City has been going down.
That is all of the functional NOAA sea level gauges in CA. Not only is sea level not “significantly altering” the California Coast, it isn’t altering it at all.
