 The global glacier evolution model, GLOGM, has been developed to accurately estimate the future mass loss of glaciers worldwide. It takes into consideration the effects of climate change, including rising temperatures and changing precipitation patterns, as well as glacial dynamics such as advancement or retreat. The model projects that glaciers will lose approximately 25 to 48 percent of their mass by 2100, depending on the emission scenario used. Additionally, it estimates that glaciers will contribute up to 157 millimeters of sea level rise under the highest emission scenario. This article was authored by Matthias E. Huss, Matthias E.
