Sea Level in the Past 20,000 Years
The image below shows warm and cool periods for the last 900,000 years and has an expanded inset for the last 140,000 years.
In the same graph, sea level rise appears to have been occurring at least for the last 18,000 years. Modern sea levels (relatively similar to highs 120,000 years ago) were achieved quite rapidly, relative to the rate of fall. Based on these numbers, 120 meters of sea level rise appears to have occurred in 18,000 years. This represents a rate of almost 6 mm/year for a rise rate.
