It’s summertime, and for many of us that means a recreational trip to the beach or coast. Worldwide, billions of people live year-round near a coastline, and these settings can be responsible for everything from buffering storms and preventing sea-level rise to fishing, flourishing tourism, and trade. For all these reasons, the acceleration of coastal erosion is an important topic to understand. A couple years ago, we sat down with Jane Willenbring, a geoscientist who says that by studying what coastlines looked like long ago, we can better understand where they are headed and how to protect them. No matter where you live, we hope you’ll tune in to better understand the forces behind coastal erosion.Have a question for Russ?
