Dr. Nils-Axel Mörner wrote a better one and sea level is actually his area of expertise.

Claim That Sea Level Is Rising Is a Total Fraud
Dr. Nils-Axel Mörner

Sea levels began to rise 18k years ago at the end of the last glacial period. They have risen about 135 meters since then which is an average of 7.5 millimeters per year. That is an average of 750 mm per century (29.5 inches) which is far more than the average over the last century.

From 1880 to 2000 sea level rose about 20 cm or just under 8 inches. Far less than the nearly 30 inches per century average over the last 18,000 years.

I was going to ask how much it has risen over past dozen millenia. They still find towns underwater.
