The Global Isostatic Adjustment (GIA) is one of the biggest frauds in climate science. They add 3mm/year to sea level rise rates – based on the idea that the sea floor is sinking due to glacial rebound.
This is equivalent to claiming that digging a deeper well raises the level of the water table.
lol, well sure it does. The lower the ground, the higher the house stands. Its that spongy like effect that terra firma is so known for…….. almost rubbery one could say.
The GIA is 0.3 mm/yr with 50% error and considerable variation worldwide.

The GMSL is a useless quantity- the local sea level variations far and away exceed the GMSL and they are what count for the effect of sea on your country.
If you read that why-do-you-correct-it link you will see that they know they are busted. Somewhere on that site (FAQ I think, not the main page) they state that they are considering maintaining *both* sets of data, adjusted and unadjusted.
They state that: “We apply a correction for GIA because we want our sea level time series to reflect purely oceanographic phenomena. In essence, we would like our GMSL time series to be a proxy for ocean water volume changes.” Which is an admission that there is modification of primary gross data. They could simply produce a time series with big fat bold letters in the title ADJUSTED MODIFIED NOT-ORIGINAL DATA. I propose that whenever someone uses one of their graphs that they immediately add in such a label themselves.
But the real reason for this corruption of original data is stated: “This is what is needed for comparisons to global climate models, for example, and other oceanographic datasets.” There you have it. Their customer is not their employer (we the taxpayers), it is instead other employees (public servants) of the taxpayers.
Needless to say, the ‘adjustment’ (corruption) of the original data could easily have been done by the AGW Modelers. What NOAA is actually doing is providing cover for their partners-in-crime. Now you will hear Mann say ‘we used the data that NOAA provided’.
Sometime later there will be an adjustment called SFTE Sea Floor Trench Expansion, and DOVWR Deep Ocean Volcanic Water Reduction, … ad nauseum. And why not, “… this correction is now scientifically well-understood and is applied to GMSL estimates by nearly all research groups around the world …”
Useless hacks that should all be fired immediately.
This is the most bold-faced “adjustment” yet. WHy hasn’t the press picked up on this … oh never mind
Where O where has my little dog gone?

S/HE/IT has missed a perfect opportunity to pass Ill Wind and taken away my fun of playfully watching its little tail wag its body cause that is where its mind appears to be!
The only thing “intelligent” I can add is:GIGO Rules!!!! Go GIGO! RAH! RAH! RAH!! Give us another Fantasy for the team!
What would they do if land fell? 😉 What a scam.
I thought they were adding it because the land was rebounding, not the ocean floor sinking.
Yes you are correct, that is the explanation.
But about Sea Floor sinking, they will get to it later (see my possible examples of future adjustments above).
Needless to say that the 800 pound gorilla in the room is the subduction of the one plate under another which is supposedly balanced out by seafloor spreading. Massive assumptions being made here of the unmeasureable. And being in perfect balance is especially questionable.
If subduction is actually slightly greater than spreading then the net result is a bigger fishbowl to hold both the fish and all the AGW melting. This would require one hell of a further adjustment.
Lake Superior must be getting deeper as the western end is rebounding.
I wonder how much the Earth’s crust varies from the Moon’s gravity. I could look it up, but I’m fat & lazy right now (and making bacon sandwiches).
Bacon makes everything easier:
“The Earth’s crust bulges by about a foot in the same way due to the Moon’s influence.”

So they’re somehow able to detect a supposed difference that is two orders of magnitude smaller than the four-times-daily variation. And all of it without making a single measurement, at that.
It all goes to show what a useless metric is any Global Average. If your house/harbor/city is rising or falling with reference to the local sea level that is what you need to plan with, not some global junk. Same goes with temperature. Look at the US, not warming, nor NZ, Australia hardly. Prepare for the worst, hope for the best. Our local city, Bathurst learned its lesson in 1988 with a 100 year flood, offered to buy all the houses on the flood plain. Only one remains. Completed a levee last year.What will the Carbon Tax do?
