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: \u2022[00:00] Introduction \u2022[00:57] Sea level geophysicist Roger Creel introduces the importance of subsidence in Arctic coastline erosion.&amp;nbsp; \u2022[02:04] Creel describes his firsthand experiences seeing how erosion, subsidence, and sea level rise are impacting Alaskan communities. \u2022[03:43] He explains how his model of coastline impacts was constructed. \u2022[05:49] He describes the results of the study. \u2022[06:43] Creel talks about the risks to coastal infrastructure. \u2022[08:10] He lists the caveats and limitations of the study. \u2022[08:54] Creel says that the coastline impacts may differ in different parts of the Arctic, depending on glacial history. \u2022[09:25] He explains the takeaways from the study. \u2022[10:39] Conclusion.
