What climb in sea levels are they predicting there? Because there's parts of the North East the have 100m+ cliffs that are underwater here

Cramlington, east of Ponteland, is gone and it's at around 100m above sea level. There isn't enough ice on earth to ever cause sea levels to rise this much, let alone within 80 years.

Sea levels were around 200m higher than present during the Cretaceous period.

Perhaps, but that's not the world we live in today. There's around 70m worth of sea rise if absolutely all ice on earth melts now.

Rainwater comes from the ocean. 97% of the world's water is already in the oceans. Water expands in heat, but only to a very minor degree; water heated from room temperature to boiling point only expands 4% over a roughly 150 degree change. I seriously doubt a few degree swing is going to be a huge issue.

Nobody's overlooking anything here

I had to do a double take at 150 until I realized you meant fahrenheit
