NOAA (accidentally) confirms there is no correlation between atmospheric CO2, temperature and sea level.

“The amount of CO2 in the atmosphere today is comparable to around 4.3 million years ago, when sea level was about 75 ft higher than today, the average temp was 7 degrees F higher than in pre-industrial times, & large forests occupied areas of the Arctic that are now tundra.”
