… when storm surges are factored in… even then the risk is low and intermittent.
The Financial Times reports:
Cities around Europe could face sea level rises of 1m or more by the end of the century when storm surges are factored in, according to research that helps address some of the biggest uncertainties about climate change.
A mix of melting ice sheets, warming oceans, storm surges and other drivers mean places such as Sheerness, at the mouth of London’s Thames river, face rises reaching just under 1m by 2100 – enough to overwhelm the capital’s existing flood protection barriers – though the risk is relatively low and any increases would be intermittent…
Build after the 1950’s the Dutch Deltaworks are capable of withstanding surges up to 6 meters.
The Waters Edge has been on the move for 18,000 years.
“Eighteen thousand years ago, the seas around northern Europe were some 400 feet lower than today. Britain was not an island but the uninhabited northwest corner of Europe, and between it and the rest of the continent stretched frozen tundra. As the world warmed and the ice receded, deer, aurochs, and wild boar headed northward and westward. The hunters followed. Coming off the uplands of what is now continental Europe, they found themselves in a vast, low-lying plain.
Archaeologists call that vanished plain Doggerland, after the North Sea sandbank and occasional shipping hazard Dogger Bank. Once thought of as a largely uninhabited land bridge between modern-day continental Europe and Britain—a place on the way to somewhere else—Doggerland is now believed to have been settled by Mesolithic people, probably in large numbers, until they were forced out of it thousands of years later by the relentlessly rising sea.”
“The most rapid rises of sea level were on the order of three to six feet a century, but because of the variable topography of the land, the flooding would not have been even. In areas as flat as modern-day East Anglia, a six-foot rise could have shifted the coast inland by miles; in hillier places, less”
