Coastal erosion in the Arctic
The thawing and erosion of Arctic permafrost coasts has dramatically increased in the past years and the sea is now consuming more than 20 meters of land per year at some

Permafrost
Lakes in the northernmost latitudes are widely considered to be a significant source of the greenhouse gas methane. In order to improve currently available climate-change projection models

in the Arctic are no longer just the domain of scientists. The shrinking sea ice and collapsing permafrost coasts are now also becoming topics on the agenda of international politics and industry. To be
