The cryosphere plays a pivotal role in global biogeochemical cycles, which becomes increasingly important as cold regions warm at rates exceeding the global average. Perturbations such as permafrost thaw, glacier retreat, and vegetation greening can have cascading effects on Earth surface processes that disrupt global biogeochemical cycles, thereby amplifying the effects of global warming. Yet, major uncertainties remain in understanding the dynamics of carbon, nutrient, and trace element cycling within these frozen environments. This session aims to bring together researchers from cryosphere, geomorphology, biogeosciences, hydrology, ecology, and sedimentology to advance our understanding of the feedbacks driving change across cold-region Earth systems. We encourage studies that encompass a variety of proxies, methods, and timescales (from modern to paleo) that integrate field observations, laboratory experiments, and modeling to unravel the complex interactions between cryosphere carbon, nutrient, and trace element cycling under global environmental changes.
