We have coastal erosion along our eastern shores. Even Whitby (home of a week long Folk Festival) with its cliffs is no immune from it. Where the river Humber joins the sea there is a spit of sand called Spurn Head. It moves around over the years. I liken it (on the timescale appropriate) to the fluttering of a flag in the breeze. It flaps, on a timescale of 100's of years.

If irt were possible, we should shove the skeptics fingers further in their ears. Then they would notice.
