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.

- kibwen 7y agoTo 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/ https://xkcd.com/1732/ It does a fabulous job of driving home the rate at which the current pace of warming exceeds geological norms.
- the-dude 7y agoWould you care to back that up? If I DDG it https://duckduckgo.com/?q=historic+sea+level+rise&t=ffab&ia=web https://duckduckgo.com/?q=historic+sea+level+rise&t=ffab&ia=... I end up at https://skepticalscience.com/Past-150000-Years-of-Sea-Level-History-Suggests-High-Rates-of-Future-Sea-Level-Rise.html 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 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?
