Reply to comment by [deleted] in Lost islands cited in Welsh folklore and poetry are plausible, new evidence on the evolution of the coastline of west Wales has revealed by marketrent

There’s actually no evidence of rapid sea level rise during that period. The sea level rise happened rather gradualist over 100-300 year periods. People forget how big the sea is and even if these lakes burst it still take a lot of time to spread.

I guess that depends on what you consider to be rapid. 20m/year is quite quick.

A glacial damn breaking would take a while to clear fron the region. We can see this today when hurricanes cause inland flooding that takes days to subside.

What flooding are you referring too? It’s probably different to what we are discussing.

There is evidence for rapid filling of the Mediterranean, Black Sea, and Persian Gulf

Of course “rapid” can mean “walking pace”

Those are isolated flooding which is not what the OP was referring too.
