Someone alerted me to this Utube video showing some aerial footage from eroding cliffs at Happisburgh on the east coast and the spectacular cliff collapse on the Cornish coast. I wouldn't have posted it but for the last comment in this news item - have a listen. The notion that cliffs collapse and erode due to climate change and sea-level rise epitomises common understanding of coastal erosion processes. As mentioned in the previous post, Holderness cliffs (and Cornish cliffs) have been eroding over the last thousands of years - cliff erosion may be exarcebated by sea-level rise, but is not the cause.
