AbstractPermafrost thaw poses diverse risks to Arctic environments and livelihoods. Understanding the effects of permafrost thaw is vital for informed policymaking and adaptation efforts. Here, we present the consolidated findings of a risk analysis spanning four study regions: Longyearbyen (Svalbard, Norway), the Avannaata municipality (Greenland), the Beaufort Sea region and the Mackenzie River Delta (Canada) and the Bulunskiy District of the Sakha Republic (Russia).

1 Introduction The Arctic coastline is more than 400,000 km long. This is about a third of the world's coastline [1]. Much of this coastline is frozen as permafrost (sediment, soil and rock that is frozen for more than two consecutive years). These coasts are often rich in ice (i.e., ground ice) and therefore highly vulnerable to thaw and erosional processes [2, 3].
