Notice that you say 'when' the sea level rises rather than 'if', and that a growing 'school of thought' whatever that may actually be.
Usual greeny brainwashed nonsense.
Well you'll be relived to know that this is some sense from a non-green, former sceptic, right-winger.

CO2 is increasing due to human emissions.
The probability density function of the equilibrium climate sensitivity to a doubling of CO2 to 560ppm(over pre-industrial) is shown by a wide body of research to centre at around 3degc (likely a little bit less).
At the current rate of emissions we are likely to hit 2xCO2 by about 2050. Which means that by then we will be committed to a global warming of 3degC. We are already feeling detrimental effects at 36% above pre-industrial CO2, e.g.
glacial recession or the 2003 European Heatwave,

We've used some 300Gtons Carbon to get to that 36% above pre industrial. There are estimated to be recoverable reserves of some 6000Gtons Carbon, mainly as coal.
And for those who think it's going to be an easy ride here in the UK...
However much global warming is, it'll be warmer here in the UK. And our weather depends crucially on the location and behaviour of phenomena like the Jet Stream. Change the pole-equator temperature gradient and you'll change phenomona like the jet stream. This rain we keep having is because of the Jet Stream (NAO/AO), we're getting storms that would normally track further north. At present the El-Nino has subsided and we could slip into La-Nina(
See here), that's messing things up all over the globe.
So whilst we're living in a global warming world - so it's impact cannot be ruled out, it seems to me the end of the El-Nino is more likely to blame for Sheffield and all.
That said, it's an indicator of the sort of events we'll very likely face more frequently in the decades to come. Best start thinking about those flood plains, and more importantly what we do with them.
