Climate effects and shifting Arctic coastlines

Author: PNAS February 17, 2025 Duration: 10:56

Erosion, subsidence, and sea level rise on Arctic coastlines

Science Sessions are brief conversations with cutting-edge researchers, National Academy members, and policymakers as they discuss topics relevant to today's scientific community. Learn the behind-the-scenes story of work published in the Proceedings of the National Academy of Sciences (PNAS), plus a broad range of scientific news about discoveries that affect the world around us.

In this episode, Roger Creel describes how compounding forces could reshape a thawing Arctic coastline.

In this episode, we cover:
•[00:00] Introduction
•[00:57] Sea level geophysicist Roger Creel introduces the importance of subsidence in Arctic coastline erosion. 
•[02:04] Creel describes his firsthand experiences seeing how erosion, subsidence, and sea level rise are impacting Alaskan communities.
•[03:43] He explains how his model of coastline impacts was constructed.
•[05:49] He describes the results of the study.
•[06:43] Creel talks about the risks to coastal infrastructure.
•[08:10] He lists the caveats and limitations of the study.
•[08:54] Creel says that the coastline impacts may differ in different parts of the Arctic, depending on glacial history.
•[09:25] He explains the takeaways from the study.
•[10:39] Conclusion.

Tune into PNAS Science Sessions for a direct line to the people shaping modern science. Produced by PNAS, this podcast offers more than just summaries of published research; it’s where you hear the candid, often personal stories behind the headlines. Each episode features concise conversations with the researchers themselves-from emerging voices to established Academy members-alongside the policymakers whose decisions are informed by this work. You’ll get a genuine sense of the questions that drive these experts, the unexpected hurdles they face in their labs and field studies, and why their findings matter right now. The scope is deliberately wide, reflecting the interdisciplinary nature of science itself, covering discoveries that range from microscopic processes to planetary-scale phenomena. This isn't about dry lectures, but about capturing the human endeavor of investigation. For anyone curious about how science actually unfolds and wants to understand the context of breakthroughs as they happen, this podcast serves as an essential, engaging resource. It connects the dots between a published paper in a prestigious journal and the real-world implications that ripple out from it.
