Fair enough. Now that I take another look, you’re talking about lowest sea level and I was talking about the start of the interglacial. The two might not necessarily coincide.
I agree. The beginning of the sea levels rising isn’t necessarily the only marker of the beginning of an interglacial period. But it’s been a steady rise since approx. 18k years ago proceeding directly into this interglacial period so it seems like something started happening around then that took things in that direction.
