Orrin H Pilkey, Linda Pilkey-Jarvis and Keith C Pilkey – Developers don’t get it: climate change means we need to retreat from the coast

Sea-level rise may be the most predictable outcome of climate change. Expanding warmer waters and melting land ice both contribute to flooding – and scientists agree that we are locked into sea-level rise for centuries to come. The question is not if we will retreat from the coast, but when. Still, the rush to develop the coast occurs at a maddening pace.

We now know that 13.1 million people are at risk of flooding along the US coast by the end of this century. A new study published in Nature Climate Change further suggests that massive migration will occur unless protective measures are taken. Since sea-level rise will speed up after the end of the century due to increased glacier and ice sheet melting, the flooding we face in this century is just the tip of the iceberg.
