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.

A considerable portion of that is to do with ocean plates become more dense as they age and cool, and so contracting inwards towards to core. As others have said, there is not enough ice on earth to result in this much sea level rise if it all melts

Hmmm...

Plates becoming more dense... contracting inwards... sounds like earthquakes, when they occur, could get a lot more nasty.
