"OK I think we have all heard that one before."

I don't know about all, but Rat has heard it.

The relative sea level trend is 2.02 millimeters/year with a 95% confidence
interval of +/- 0.22 mm/yr based on monthly mean sea level data from
1924 to 2024 which is equivalent to a change of 0.66 feet in 100 years.

By the mid-1970s when I got my BS in Marine Science, oceanographers were grappling with what was causing the sea level rise they have been measuring for decades. They had settled on thermal expansion of the oceans. Glacial melting was mooted as a possibility, but there were no good ways to measure that until the ICESATs in the 1980s. From 1900 to the 1970s, they had measured a steady rise of around 15cm or so, globally. Say 6 inches. If marine scientists and oceanographers were knocking down big bucks to peddle the global warming hoax, I'd have probably stuck with it instead of moving into computers. Just sayin'. The fact of the matter is that the last time CO2 levels were where they are now, sea level was meters higher than it is now. Admittedly, the CO2 levels had been dropping for millions of years to get to that point and we are experiencing the reverse, but that is cold comfort. Compared to now, that CO2 level was changing very, very slowly. The changes we see in a decade took 10s of thousands of years back then. Are you familiar with the word "hysteresis"?
