well, I was referring to the age of the red lady of Paviland, who is estimated as being 40000 years old and we are told that at that time the shoreline was some way South West of Ireland. I would estimate that sea levels have risen by hundreds of feet since then. Clearly it would be difficult to measure the rise from 40000 to 22000 years ago, but I guess you understand the basis of my question.
Sea levels have risen by no more than 40 cms in the last 200 years, but based on what we are told about the levels at 40000 years ago, most of the rise would appear to have happened pre Roman times.
If you ever venture to Swansea along the coast road, you will pass right by the new UNI campus. To your right will be a row of older houses, which were built before WW2. The road feeding them to the North was originally the main road to Swansea even in my time. My mother distinctly remembers at exceptionally high tides than the sea used to lap the edge of the long gardens of those houses. That's where the main road sits now and the campus would be under a few feet of water. So, what's happening to sea levels there? Granted, it's more likely that the UK is tipping down in the East and coming up in the West. But I'm no expert.

Historic variations in sea levels. Part 1: From the Holocene to Romans | Climate Etc.
Global sea level rose by about 120 m during the several millennia that followed the end of the last ice age (approximately 21,000 years ago), and stabilised between 3,000 and 2,000 years ago. Sea level indicators suggest that global sea level did not change significantly from then until the late 19th century. The instrumental record of modern sea level change shows evidence for onset of sea level rise during the 19th century. Estimates for the 20th century show that global average sea level rose at a rate of about 1.7 mm yr–1.”
