This paper celebrates Professor Yongqi GAO's significant achiev.ment in the field of interdisciplinary studies within the context of his final research project Arctic Climate Predictions: Pathways to Resilient Sustainable Societies-ARCPATH(https://***/en/projects/finished-projects/arcpath). The disciplines represented in the project are related to climatology, anthropology, marine biology, economics, and the broad spectrum of social-ecological studies. Team members were drawn from the Nordic countries, Russia, China, the United States, and Canada. The project was transdisciplinary as well as interdisciplinary as it included collaboration with local knowledge holders. ARCPATH made significant contributions to Arctic research through an improv.d understanding of the mechanisms that driv. climate v.riability in the Arctic. In tandem with this research, a combination of historical inv.stigations and social, economic, and marine biological fieldwork was carried out for the project study areas of Iceland, Greenland, Norway, and the surrounding seas, with a focus on the joint use of ocean and sea-ice data as well as social-ecological driv.rs. ARCPATH was able to prov.de an improv.d framework for predicting the near-term v.riation of Arctic climate on spatial scales relev.nt to society, as well as ev.luating possible related changes in socioeconomic realms. In summary, through the integration of information from sev.ral different disciplines and research approaches, ARCPATH serv.d to create new and v.luable knowledge on crucial issues, thus prov.ding new pathways to action for Arctic communities.
