Rising sea levels threaten coastal communities (BBC): Nearly 200,000 properties in England may have to be abandoned due to rising sea levels by 2050, a report says. It looks at where water will cause most damage and whether defences are technically and financially feasible.
There is consensus among scientists that decades of sea level rise are inevitable and the government has said that not all properties can be saved. About a third of England's coast will be put under pressure by sea level rise, the report says.
"It just won't be possible to hold the line all around the coast," says the report's author Paul Sayers, an expert on flood and coastal risks, adding that tough decisions will have to be made about what it is realistic to protect. "These are the places we are going to hold, and these are the places we're not going to hold, so we need that honest debate around how we're going to do that and support communities where they are affected."

Nearly 200,000 properties at risk of being lost due to sea level rise – study (Yahoo News): For a thousand miles of English coast (1,600-1,900km), there will be high pressure to rethink the current policy to hold the line as it may become unfeasible due to rising costs, or technically impossible, the study says.
That accounts for around 30% of the coastline where hold-the-line policies are in place ... with a proportion [of properties] likely to need relocating. The study says it is not possible to say how many of them will have to be moved, as that will be a matter for Government, policy and funding for flood defences.
The figure is on top of the 30,000 to 35,000 properties already identified in areas which have a policy to realign the coast. The study focuses on the impacts of flooding and does not include properties directly at risk from coastal erosion such as clifftop homes [see video below for coverage of that].
Those most at risk are single communities, those with dispersed clusters of homes and buildings on a long flood plain such as the Somerset Levels, areas with a narrow space between the shoreline and rising ground, and small quay and coastal harbour communities of the type found across Cornwall.
The analysis highlights that those local authorities with the largest challenge in responding to sea level rise, through to 2050s and 2080s, with significant uncertainty regarding the ability to “hold the line” in the longer term in some locations, are likely to be: North Somerset; Wyre; Swale; Tendring; Maldon; Suffolk Coastal; North Norfolk; Cornwall; Medway; and Sedgemoor...
