Holocene sea level rise: The rise, of ~60m, took place over most of the Earth as the volume of the oceans increased during deglaciation and is dated at 11,650–7000 cal. BP That's a sea level rise of 13 mm/year, on average. Current seal-level rise estimates are about 4 mm/year, and model projections point to as much as 19 mm/year by 2100. It's certainly comparable. These are however relatively slow processes on the scale of a human lifetime, and one could argue human civilization could adapt to these conditions... at some cost, which might be quite high.
