Arctic Glacier Melt Uncovers 1500 Miles of Coastline, Posing Risks and Rewards
2025-03-28
A study in Nature Climate Change reveals that melting Arctic glaciers have exposed approximately 1500 miles of coastline since 2000, primarily in Greenland. The retreating ice unveils valuable mineral deposits, but also creates vulnerability. Newly exposed coastlines, lacking the stabilizing effect of ice, are susceptible to erosion and landslides. A dramatic example occurred in September 2023, when a thinning coastal glacier in eastern Greenland collapsed, triggering a 350-foot tsunami that registered globally. This highlights the significant risks and challenges posed by climate change.
