Strike 4.
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?
I wasnt looking for it, just used it to escape a short faced bear on one of my youthful wooly rhinoceros hunts.
How'd I do on the math.
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.
Clueless.
What did I get wrong
That the "average" is meaningful in this discussion.
It is, only as a means of presenting 20th century sea level rise as well, ..average.
Within the period of written human history, it is not.
Im tired of slapping you around.
I got shit to do.
I got shit to do.
Who painted the pictures on the cave walls in Cosquer.
You could start with reading the article I linked. All you need to do is look at the pictures to get the point.

Lol! You don't even read the articles you link.
I'm reading some stuff on prehistoric cave art in France, and I see this cutaway of the cave at Cosquer.
The cave entrance is 37 meters under water, but 18500 years ago people walked in there and painted the walls.
It was easily relatable to this discussion so I did the very simple math.
Espola's argument seems to be that since people started writing, the sea level has risen more sharply in the 20th century than at any time before,...unless you count the sea level rise before they started writing, (just painting) in which case, its about average.
Im in the process of reading the link e posted.
Some good nuggets in there. He should read it.
