The rate at which the sea levels rose was much slower and much of that water was frozen in the arctic. The past couple of centuries are exceptionally different.

To that end, here's one of my favorite XKCDs ever, which is a long-form chart of Earth's average temperature for the past 22,000 years, including notes about the advancing and receding of ice and sea levels: https://xkcd.com/1732/ It does a fabulous job of driving home the rate at which the current pace of warming exceeds geological norms.

Would you care to back that up? If I DDG it https://duckduckgo.com/?q=historic+sea+level+rise&t=ffab&ia=...
I end up at https://skepticalscience.com/Past-150000-Years-of-Sea-Level-... ( that's right ) :
"During all episodes of major global ice loss, sea level rise has reached rates of at least 1.2 metres per century (equivalent to 12 mm per year). This is 4 times the current rate of sea level rise."
Not relying on one opinion, I view the XKCD of the sibbling : no sources.
Next hit on DDG : https://en.wikipedia.org/wiki/Past_sea_level :
"Observational and modeling studies of mass loss from glaciers and ice caps indicate a contribution to a sea-level rise of 2 to 4 cm over the 20th century. "
Which is very low.
Would you care to back up your statement?
