This document describes the main goals of the special issue, which aims to summarize the scientific knowledge about climate change across the Arctic in layman terms which can be used for communicating science to policymakers. The goal of the special issue is to summarize the scientific knowledge to native communities and be vehicle for improving the exchange of knowledge between scientists, the public, and the native communities. The cross disciplinary nature of the special issue and the involvement of partners from different EU projects will allow wide dissemination of the outreach activities within ITRAOS. A paper has already been published, and we expect several other manuscripts to be submitted by the end of November 2021 (which is the current deadline for the special issue).
