Permafrost
Arctic coasts are characterized by sea ice, permafrost and ground ice. This makes them particularly vulnerable to the effects of climate change, which is already accelerating rapid coastal

Permafrost
According to estimates, Alaska's thawing permafrost soils cost the USA several 100 million dollars every decade – primarily because airports, roads, pipelines and settlements require relocation

Gallery Muostakh Island is a slender crescent of land in the Laptev Sea with ice-rich Yedoma permafrost. The sun has set over Muostakh Island in the central Laptev Sea. A driftwood fire on the beach provides [...] provides warmth at the end of the summer as we ready to return to civilization. Since permafrost begins to degrade as soon as it is submerged, for example as the coastline retreats, we often work close

inundation of coastal permafrost areas and their role in the permafrost carbon climate feedback.
