I have the good fortune of getting invited to go boating out of Portsmouth a few times each summer, and we pass the lighthouse on our way out to sea. High tide, low tide, you, me, anyone who looks can tell there is nothing to see. There is no connection between sea level and “carbon” emissions. And you do not have to take my word for it.
The Journal of Island and Coastal Archaeology published research this year that documents sea level rise through geologic observation and histories related to land bridges that are now submerged. Flooded by actual accelerated post-ice age melt.
A new study reminds us that, 8200 years ago, near-global sea levels rose 6.5 meters in a span of just 140 years. This is 470 centimeters per century, 4.7 centimeters per year, during a period when CO2 levels were alleged to be a “safe” and stagnant 260 ppm.
To put this change rate in perspective, global sea levels rose at a rate of 1.56 millimeters per year from 1900 to 2018, including 1.5 mm per year rate during the more recent period from 1958-2014 (Frederikse et al., 2020, Frederikse et al., 2018). This is just under 16 centimeters per century or sixteen tenths of a centimeter (0.16 cm) per year.

We haven’t seen anything remotely close to this in the modern era with 400 + PPM of CO2 in the atmosphere. It would be appropriate to ask Climate zealots how that’s possible. Low CO2, high rate of SLR. And now (supposedly) high CO2 and very limited SLR. And sure, it happened before (so it could happen again), but none of the drivers they insist require all this spending and sacrifice were present. And absent some explanation aside from shut up and trust us, their exhortations look like little more than milking a sick cow to feed a deranged cult.
