Meeting Review of the Cryospheric Ecosystems Conference, 1-4 September 2025, Poznań, Poland

The Cryospheric Ecosystems Conference, held at Adam Mickiewicz University in Poznań from September 1 to 4, 2025, brought together 80 scientists, researchers, and students from 15 countries. The conference was held as part of the International Year of Glaciers' Preservation 2025, providing the ideal context and platform for sharing the results and discussions on recent discoveries, emerging threats, the latest techniques, and future projects. The conference highlighted the importance of cryospheric environments, such as ice sheets, glaciers and snow, which host unique biodiversity. The event covered the cascading effects of global warming on glacier retreat and biodiversity, the role of phototrophs in snow and ice, the biogeochemical cycling of fundamental elements such as carbon, nitrogen and phosphorus, and pollutants in cryospheric environments. Here we present the key outcomes and discussions of the conference, emphasizing the importance of cryospheric ecosystems monitoring and protection.
