N2 - It is essential to improve our understanding of glaciers and their effects on sea levels, ecosystems, and freshwater resources in a changing climate. To this end, we implemented a framework for three-dimensional, high- resolution, regional-scale glacier simulations in the Com- munity Ice Sheet Model (CISM v2.2), using higher-order ice-flow dynamics previously applied to the Greenland and Antarctic ice sheets. Here, we present the modeling frame- work and its application to the European Alps glaciers at a 100 m resolution, using protocols from the third phase of the Glacier Model Intercomparison Project (GlacierMIP3). The model results align with observations and other glacier mod- els, indicating that Alpine glaciers will lose more than half their current mass if present-day climate conditions persist, with near-total loss under warmer scenarios. This new devel- opment integrates glacier and ice sheet systems in a common modeling framework and will support advances in coupled land ice–Earth system assessments across timescales in the Community Earth System Model (CESM).
