In the Arctic, climate warming causes permafrost degradation. Thawing permafrost has significant effects on human health and well-being, infrastructure, ecosystems, and climate, from local to global scales. Here we provide examples of the many consequences of permafrost thaw in the Arctic permafrost region, paying particular attention to conditions in the Nordic and Russian Arctic, and interactions between the different effects. We discuss approaches used in adaptation to permafrost degradation from technological solutions to institutional and behavioural change. Our findings suggest that in-depth understanding of the various feedbacks and cross-border effects are required to adapt to the multiple effects of the thawing of permafrost. Successful adaptation requires coherence between the approaches and dialogues between stakeholders.
