Ground in Transition: Thawing Permafrost at the Arctic Coast

This image captures an actively eroding permafrost cliff on Herschel Island-Qikiqtaruk along the western Canadian Arctic coast. The exposed ground ice and collapsing tundra surface illustrate rapid thaw processes driven by rising temperatures and coastal dynamics. As permafrost degrades, previously stable soils lose cohesion, leading to mass wasting and shoreline retreat. These changes not only reshape Arctic landscapes but also release stored carbon and impact coastal ecosystems and infrastructure. Such sites are critical for understanding the feedbacks between climate warming, permafrost stability, and coastal erosion in polar regions.
