The Historic White Cliffs Are At Risk Of Disappearing, Says New Research

Researchers warn that England’s classic and historic White Cliffs of Dover would likely vanish if left unprotected. It has been eroding 10 times quicker in the last 150 years because of climate change and poor management of beaches.

Scientists have attributed the acceleration to the loss of beach beneath the cliffs, which historically provided a buffer to the sea.

Sea walls and groynes have been erected to protect specific beaches, but they have come at the expense of large sections of the East Sussex coastline.

Poor coastal management has made the coast vulnerable to increasingly stormy seas caused by global warming, the researchers found.

A spokesperson said: “[It] suggests that the chalk front on the cliffs is in danger of disappearing altogether if something is not done to protect them.”

The erosion rate is approximately 22-32cm a year, according to the study.

Scientists assessed historical rates of erosion by measuring changes in rock that occur when it’s exposed to falling particles from space.

The greater the amount of an isotope of beryllium in the rocks under the cliffs, the longer the rock has been exposed, enabling estimations of erosion.

The UK and US research team is now set to apply the technique to other sections of the UK coastline.

Over the next few decades, nearly 7,000 homes in England and Wales are expected to be swallowed up by coastal erosion.
