The Permafrost Young Researchers Network (PYRN) is an international network fostering innovative collaboration, seeking to recruit, retain, and promote future generations of permafrost researchers. Established in 2005, in the framework of the 2nd International Conference on Arctic Research Planning (ICARP II), PYRN is evolving and expanding its network, bringing together young and enthusiastic permafrost scientists from all around the world. We strongly benefit from our cooperation with the Association of Polar Early Career Scientists (APECS) and our overarching organization, the International Permafrost Association (IPA), as well as from partnerships with Climate and Cryosphere Project (CliC) and Polar Educators International (PEI). Currently, more than 1,200 members are involved in PYRN, including from natural and social science, engineering and humanities.
