This is not new - London is sinking. We've known it for years. But it's more significant if you combine it with sea level rise. This study combines the GPS brains of IESSG, the tidal knowledge of Proudman Oceanographic Laboratory (who have moved from a gorgeous old building south of the Mersey, which I visited, to a more 'standard' building in Liverpool) and Nigel Press Agency (who I know as imaging gurus).
I love the link which came with the BBC article about the Millimetre Men. Next stop? Millimetre Women?!!
