Also by studying the many now underwater ancient cities around the world we can surmise that ocean levels have risen substantially over the course of human history. We also know from soil samples that ocean levels have been much higher than they are today.
Thนหำ ancient places are all in the Greek Archipelago. It sits on a tectonic plate that's sinking several cm each year. It's got nothing to do with ocean levels.

And what's the inane question above? Of course would CO2 fall swiftly when humans weren't around anymore, the point is to achieve it while humanity survives.
