Take a look at real sea level rise at https://tidesandcurrents.noaa.gov/sltrends/sltrends_station.shtml?id=8724580
Now take a look at the historical sea level rise at https://en.wikipedia.org/wiki/Past_sea_level and note the Post Glacial sea level rise, sea levels are rising but slowly and consistently over the last 2000 years.
Does sea level and CO2 concentration in the atmosphere correlate? Check out https://www.climate.gov/news-features/understanding-climate/climate-change-atmospheric-carbon-dioxide and scroll down a little to the second chart and see the recent exponential rise in CO2 and compare the the flat sea level rise over the last hundred years. This is what convinced me that sea level rise is not correlated with CO2 levels.
