A Second world War lookout post leaning alarmingly and about to tumble over the edge of the cliff near Aldbrough on Yorkshires East Coast, UK. The coast is composed of soft boulder clays, very vulnerable to coastal erosion. This section of coast has been eroding since Roman times, with many villages having disappeared into the sea, and is the fastest eroding coast in Europe. Climate change is speeding up the erosion, with sea level rise, increased stormy weather and increased heavy rainfall events, all playing their part.

A holiday chalet in the sand dunes at low Newton by the Sea on Northumberland's coast stands precarioulsy close to the edge following a severe storm surge in December 2013 that caused considerable erosion to the sand dunes.
