The illustration above is a cut away rendering of the Cosquer cave in Southern France.
The cave entrance is 37 meters below sea level today.
18,500 years ago, people entered the cave by foot, and painted images of animals on the cave walls.
37 meters = 37000 millimeters.
If you divide 37000 by 18500, you get 2.
2 millimeters per year average sea level rise.
The 20th century sea level average rise per year was 1.8 millimeters.

btw, I came up with this on my own.lol.

You discovered the cave?

But it wasn't a simple ramp. Sea level came up relatively rapidly ("relatively" as in several thousand years) as the ice age melted off and then stabilized about 1 meter below present levels about 7000 years ago.
1 meter = 1000 millimeters.
If you divide 1000 by 7000 (about the length of time since the last post-ice-age meltoff stabilized), you get 0.14.
0.14 millimeters per year average sea level rise.
The 20th century sea level average rise per year was 1.8 millimeters.

What follows is a reference to an actual scientific article with data to back up what I just posted.

My math is perfect.
The average over 18500 yrs is 2 millimeters.
The 20th century average is 1.8 millimeters.
We agree.
Ive stated all along that there are drastic swings in climate over sometimes very short periods.
The 20th century "man driven" sea level rise is within the average.
The average is just that. An average.
