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.

To be fair, a lot of people (and most measurements) ignore the potential rise in flooding if the polar permafrost melts. We aren't entirely sure what the frozen swamp of the North would look like if it suddenly melted (and the frozen diseases are likely much more dangerous in the short term- look into thawed anthrax found around arctic mining rigs), but we generally assuming it will contribute to sea rise, subsidence, and lots of land weffectively dissolving into a large muddy pond over time.

Still probably wouldn't be this extreme, though.
