Colorado glacier and snowfield recession

Overview

Colorado’s glaciers and perennial snowfields have experienced significant loss due to record-low snowfall and extreme summer heat. In September 2026, the St. Mary’s Glacier snowfield, which had functioned as a perennial snowfield for a century, melted completely for the first time in recorded history. This disappearance prompted mourning ceremonies hosted by climate activists from Glacier Nation and The Green House Connection Center to highlight the urgency of global warming.

Research from glaciologist Dan McGrath of Colorado State University indicates that the rate of ice loss in the region has doubled compared to the previous five years. Specific findings show the Andrews Glacier thinned by more than 3.7 meters, the Arapaho Glacier lost nearly 3 meters, and the Isabelle Glacier shrank by approximately 2 meters. These patterns of rapid ice loss are reportedly being observed globally, including in the European Alps.
