Abstract The Laurentide Ice Sheet was the largest global ice mass to grow and decay during the last glacial cycle (~ 115 ka to~ 10 ka). Despite its importance for driving major changes …
While there are numerous hypotheses concerning glacial–interglacial environmental and climatic regime shifts in the Arctic Ocean, a holistic view on the Northern Hemisphere's late …

Key Points Since the 1990s, parts of the Yukon coast are in a phase of enhanced shoreline retreat Gravel features grew in areal extent since the 1950s and were largest in the latest …
Permafrost landscapes are changing around the Arctic in response to climate warming, with coastal erosion being one of the most prominent and hazardous features. Using drone …
Permafrost thaw in the Arctic enables the biogeochemical transformation of vast stores of organic carbon into carbon dioxide (CO2). This CO2 release has significant implications for …
