I found this an interesting graphic and story.
The story lead me to Earth Time
where I can watch the actual coastline change each year from 1984 to 2016. I have witnessed it happening here in SC at Cape Romain where I often paddle the coast, but it is way cool to see the satellite photos as time lapse. Just zoom in on your favorite coast. Cape Romain has had some dramatic changes as Sandy Point at the mouth of Five Fathom Creek has disappeared altogether, and the Lighthouse Island, Cape Island area has also changed quite a bit.
