Mesolithic people did inhabit low-lying coasts later drowned by rising postglacial seas, but the video's 22× comparison is wrong. The quoted Mesolithic rate of 8.4mm per year is about 33 inches per century; against the recent global rate of roughly 13 inches per century, it was about 2.5 times faster. The date conversion also needs fixing: 8,000–6,000 calibrated BCE is about 10,000–8,000 years ago. The 25m figure is not a uniform regional value; the Orkney evidence gives up to roughly 20m lower.
Mesolithic sea-level rise was about 2.5 times today's rate, not 22 times
Key facts
- The date conversion is wrong: 8,000–6,000 calibrated BCE equals about 10,000–8,000 years ago, not 7,000–8,000 years ago.
- Mesolithic lowlands in north-west Europe, including Doggerland, were submerged as postglacial sea levels rose.
- Sea level was lower by a varying regional amount; the cited Orkney evidence gives up to about 20m below present, so 25m should not be presented as a universal value.
- A Mesolithic sea-level rise rate of 8.4mm per year equals about 33 inches per century.
- Against a recent global rate of roughly 13 inches per century, or 3.3mm per year, 8.4mm per year is about 2.5 times faster, not 22 times.
