Not Your Fault: Sea Rise Is Not Accelerating

First-of-Its-Kind Study Finds Sea Level Rise Has Not Accelerated Because of Climate Change
A new first-of-its-kind study by Dutch researchers finds no evidence of a global acceleration in sea level rise because of climate change.
The peer-reviewed paper, “A Global Perspective on Local Sea Level Changes,” published in the Journal of Marine Science and Engineering last month is the first study to be based on local data taken from coastal sites around the world, rather than on models based on extrapolations.
That last bit is rather important. I’ve been looking at actual data from NOAA for decades directly captured, rather than extrapolated for decades, and none really shows any sort of statistically significant acceleration. If any. Many gauges are barely risings, some are going down.
The study, which was conducted as an analysis of more than 200 tide-gauge stations worldwide, cuts against the long-standing belief among climate scientists that climate change is leading to rapidly accelerating sea level rise.
The research, conducted by Dutch researchers Hessel Voortman and Rob de Vos, found that the average rate of sea level rise in 2020 is only around 1.5 millimeters per year, or 15 centimeters per century.
“This is significantly lower than the 3 to 4 mm/year often reported by climate scientists in scientific literature and the media,” Voortman told independent journalist Michael Shellenberger.
15 centimeters is just under 6 inches per century, at the lower end of average for a Holocene century, which encompasses warm and cool. Heck, the worst station in the US, Grand Isle, Louisiana, would only be 3 feet per 100 years, and much is substance. But, the cult is yammering about dozens of feet by 2100
The study was also unlike previous studies of its kind in that it was conducted without external funding; Voortman does not belong to a university, instead he is a hydraulic engineer of 30 years who is involved in flood protection and coastal-infrastructure adaptation projects all over the world.
“From practice, I had already encountered the situation that sea level projections were exceeding sea level observations,” he said.
Well, observations are not scary like projections. It’s a very long article, worth the read. But, you won’t find it in the Credentialed Media, because it is very inconvenient for the cult. They’ll just continue with their sea rise doom narrative.
PS: I’m not discounting sea rise: it’s expected during a Holocene warm period. I’m discounting that it is doomy, because it is half a foot to a foot lower on average than would be expected.
