I have had a look at this and it feels rather "sensationalist". If seal levels rise significantly, and it is a big "if", then yes things could get difficult. At the moment though I have reservations.

well coastal erosion is a big thing at the moment, all along the south coast of England, most of that is caused by the sea undermining the land.

@yokel It is. Some of that is that our, very aged, coastal defences are no longer up to the job. This is a particular problem near where I live, we have several schemes to rebuild harbour defences etc, where nothing more than routine maintenance has been carried out for decades.

thankfully we are inland so none of this affects us.

@yokel Potentially it does, as a large population, displaced from the coast due to sea level rise, would need somewhere to go, and would doubtless head inland. 

possibly yes, but I think any sea rise will be gradual so any influx would hopefully be minimal and slow.

@yokel I do too, probably not even within our lifetimes, but as with everything there is a possibility. You never know you might end up with your place being a beachfront property 🤣 🤣  I wonder what would have happened tot he rest of the UK at that point - mostly under water I would think.

I remember years ago being shown round "The Green Shop" who are specialist in eco home building and finishing and there being a map on the wall showing a supposition of what would be left of the UK if all the planet's ice melted, and it was only the highest areas, Dartmoor, Bodmin moor, the Cotswolds etc.

that would take some doing seeing I am some 25+ miles from the nearest coast (north Cornwall) right in the middle of the county and some 10 miles north of Dartmoor.

I saw one of those maps some time ago and it was mostly coastal and low lying areas that were affected, take the Somerset Levels for instance, they are actually BELOW sea level so any flooding would swamp the area, Glastonbury Tor will be an island again which it was before the Romans and later the Monks pumped out the water.

Indeed, it only takes a failure of the sluice gates to return the levels to their watery state.

well they dont even need that, all they have to do is stop clearing out the silt and the rivers over top in the winter, thats whats happened before.

@yokel Yes, it was.

for many years the rivers and rheams werent dredged and they had builds ups of silt and other material which caused the flooding, I believe its done more regularly now.
