Coastal permafrost environments are undergoing profound change in response to climate warming. While the response of thawing terrestrial permafrost has been the subject of extensive investigation, less is known about the associated changes occurring in coastal and offshore environments, or the impacts on coastal communities and ecosystems.
This Rapid Response Assessment (RRA) aims to raise awareness about the importance of coastal permafrost and to identify urgent research needs. The assessment strives to consider the relevance of this change to people living along the Arctic coast, infrastructure, and terrestrial and marine ecosystems. Potential permafrost feedback mechanisms that could accelerate the rate of change in the future at local, regional, and global scales are also reviewed.
The assessment shows there are significant knowledge gaps pertaining to coastal and offshore permafrost that should be addressed by the scientific and engineering communities, as well those responsible for developing policy in the Arctic. Arctic peoples living along the coast as well as the global community urgently require action on these knowledge gaps in order to address the ongoing effects of climate warming. It is imperative that Arctic peoples have a more active role in coastal permafrost studies, participating in the design and undertaking of scientific and engineering activities.
