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.

Chapters:

(00:00:00) Introduction

Russ Altman introduces guest Jane Willenbring, a professor of Earth systems at Stanford University.

(00:01:30) What Causes Coastal Erosion

The natural processes that build up or break down coastal regions.

(00:02:58) When Coastlines Grow

Where and how coastal buildup can still occur, especially near rivers.

(00:04:11) Measuring Coastal Erosion

The technological and geological measurements used to track change.

(00:06:12) Dating Coastal Rock

Using cosmic radiation to help measure long-term erosion rates.

(00:07:48) Archaeology & Shifting Settlements

How ancient coastal settlements reflect environmental change.

(00:09:03) Tectonics vs. Erosion

Differentiating between sea level rise and tectonic land uplift.

(00:10:09) Infrastructure at Risk

The dangers of coastal erosion to critical infrastructure.

(00:12:12) Science Meets Policy

Why long-term erosion timelines complicate policymaking.

(00:14:11) Real-World Responses

Examples of successes and failures due to policy inaction.

(00:15:14) Disadvantages of Building Bridges

The unintended effects of building bridges and barriers.

(00:16:11) “Unzipping” Landscapes

How rivers and streams carve landscapes from the inside out.

(00:17:47) Sea Level Rise & Coastal Changes

The mechanics of sea level rise and how it increases erosion.

(00:19:25) Beaches as Natural Defenses

Why wide beaches are crucial to the protection of coastlines.

(00:20:42) Cliff Collapse & Beaches

What happens when sand is lost due to erosion or human intervention.

(00:22:11) The Social Impacts of Coastal Erosion

The effects of coastal erosion on different socioeconomic classes

(00:24:11) Public Health Risks of Coastal Erosion

The different health and infrastructure risks posed by unmanaged erosion.

(00:26:05) Vegetation, Kelp, & Green Solutions

The potential for vegetation and kelp to help soften coastal impact.

(0028:43) Conclusion
