Cryospheric change poses multiple risks to the environment, ecosystems, and society across both polar and mountain regions. These challenges are wide-ranging: from the consequences of shifting meltwater production for water security to the impact of sea ice decline on traditional hunting; the sudden detachments of mountain glaciers to the slow hazard of sea level rise for low-lying regions. Changes to cryospheric land and seascapes also feed into socio-cultural pressures that change the ways in which people interact with and benefit from these environments. This session provides a platform to discuss the varied consequences of cryospheric decline and the potential solutions to increase the resilience of impacted regions and communities, with a broad and inclusive focus. We invite contributions on a range of topics focusing on the challenges of cryospheric change, including but not limited to: individual and cascading hazards; ecological impacts; resource security; and environmental risk. Additionally, we welcome case studies that highlight mitigation and adaptation strategies to address cryospheric decline and associated risks, and examples of communication beyond the scientific sphere. To effectively address the impacts of cryospheric change, natural and social scientists must work together, and in collaboration with stakeholders who live in these regions, so we welcome research that spans disciplinary boundaries and diverse ways of exploring and understanding these changing environments.
