Landscape Processes and Carbon Cycling in Cold Regions
Session ID#: 252187
Session Description:
Climate warming in high-latitude and high-altitude cold regions is occurring faster than the global average, accelerating permafrost thaw, glacier retreat and vegetation greening. These shifts trigger cascading effects on Earth surface processes and disrupt carbon cycle, which would have feedback to climate change. However, key uncertainties remain about how geomorphic processes and carbon dynamics interact in these rapidly changing environments. This session invites contributions that investigate these geomorphic-carbon linkages, particularly within catchments, lake basins, and coastal systems affected by thaw, melt, and evolving hydrology. We encourage diverse approaches—including fieldwork, geochronology, geochemistry, remote sensing, AI, modeling, and lab experiments—to help reveal the physical and biogeochemical processes shaping these landscapes. By bringing together researchers from cryosphere, geomorphology, biogeosciences, hydrology, ecology, and sedimentology, this session aims to advance understanding of the crucial feedbacks driving change across cold-region Earth systems.
