The Remains of the Godwin battery on the beach at Kilnsea at the head of Spurn point on Yorkshires East Coast, UK. Initially constructed during the First World War, the Godwin Battery was added to during the Second World War. It comprised of gun emplacements, search light, barracks, officers’ mess, and a hospital. This section of coastline is the fastest eroding coastline in Europe. The soft boulder clay cliffs are easily eroded and have been eroding since Roman Times, but recently the climate change impacts of increased stormy weather, increased heavy rainfall events and sea level rise have accelerated the rate of erosion. The average rate of attrition is 1.5metres per year, last year it was 5 metres.

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.
