Part of situation: Colorado glacier and snowfield recession (2 clusters)

Colorado glaciers experience dramatic thinning due to extreme weather

Colorado glaciers climate change Dan McGrath glacier thinning Rocky Mountains

New research indicates that Colorado’s most prominent glaciers thinned significantly during 2026, driven by record-low snowfall and extreme summer heat. Glaciologist Dan McGrath from Colorado State University reported that the rate of ice loss has doubled compared to the previous five years.

Specific findings include the Andrews Glacier thinning by more than 3.7 meters (12 feet), the Arapaho Glacier losing nearly 3 meters (10 feet), and the Isabelle Glacier shrinking by approximately 2 meters (6.5 feet). Additionally, the St. Mary’s Glacier, a popular site for hikers and skiers, melted away completely by September.

McGrath noted that these patterns of rapid ice loss are not isolated to Colorado but are being observed globally in regions such as the European Alps and other mountain ranges across the western United States.
