ALAN PAINE, Dana Point
I live in Dana Point and have noticed several recent articles regarding the loss of Orange County beaches due to sea level rise.
The articles are attributing the destruction of Capistrano Beach to this rise in the sea level.
I have a few problems with this conclusion, as follows:
1) If Capo Beach was destroyed from sea level rise, why was the beach normal this last summer like most summers? Why was it destroyed only in the last winter? Was it a bad winter storm that eroded the beach?
2) I checked the sea buoy at Doheny Beach and researched historic buoy levels and didn’t see a dramatic change in the typical 2.0 mm average over many decades that would support this sudden winter storm loss of Capo Beach. Please research National Oceanic Atmospheric Administration buoy data.
3) If it’s sea level rise, why is it not happening now? Only last winter, and only Capo Beach?
4) I researched and found many problems with the idea that there has been a drastic change in sea level: a newly published paper by Frederiske et al. 2018, just last year. Oceanographers estimate that global sea levels rose at a rate of only 1.42 mm per year between 1958 and 2014.
That figure closely coincides with the results of Dr. Simon Holgate from 2007. According to the Holgate study: “The rate of sea level change was found to be larger in the early part of last century (2.03 ± 0.35 mm/yr 1904–1953), in comparison with the latter part (1.45 ± 0.34 mm/yr 1954–2003).”
It just doesn’t make sense that if the sea level rose from supposed arctic ice melting, why would there not be a continuous problem? Not just a single severe winter storm that destroyed the Capo Beach.
