Greenhouse gas concentrations (GHGs)—methane (CH₄), carbon dioxide (CO₂), and nitrous oxide (N₂O)—are rising at accelerating rates. Emerging evidence suggests that warming-induced emissions from natural systems, such as wetlands, inland waters, thawing permafrost, and fire-prone landscapes, may be significant contributors. Given their significant influence in climate regulation, water quality, and ecosystem health, it is crucial to better understand these biogeochemical processes. This session invites submissions that integrate field observations, remote sensing, and modeling to quantify GHG fluxes or improve understanding of biogeochemical processes from permafrost, wetlands, rivers, lakes, and riparian zones; assess their environmental drivers; and reduce uncertainties in global budgets. Topics include process-based biogeochemical modeling, machine learning and AI applications, atmospheric inversions, isotopic and chamber measurements, and strategies for improving observation networks. Studies that advance understanding of lateral fluxes, ecosystem–atmosphere interactions, and pathways for incorporating natural feedbacks into Earth system models and mitigation planning are also encouraged.
