Through 2024, mountain glaciers in have lost more than 27 meters of water equivalent since 1970. That's roughly the same as slicing a 98-foot slab off the top each glacier. WGMS data.
Retreat of Alaska’s Muir Glacier between August 1941 and August 2004. In the six decades between the photos, the glacier has retreated far into the mountains. Photos from the National Snow and Ice Data Center.
Cumulative ice loss from mountain glaciers in the World Glacier Monitoring Service (WGMS) "reference network," a collection of 30-40 glaciers from different parts of the world that have at least 30 years of observations. On average, these glaciers have lost ice equivalent to nearly 25 meters (82 feet) of water pooled across their surface areas. NOAA Climate.gov graph, based on data from WGMS.
Retreat of southeastern Alaska’s Muir Glacier between August 1941 and August 2004. Historically, Muir Glacier was an iceberg-calving, tidewater glacier. Its terminus was grounded in the waters of Muir Inlet, a narrow opening to Glacier Bay. In the six decades between the two photos, it has retreated so far that it's terminus is now inland. Photos from the National Snow and Ice Data Center’s collection of repeat photography of glaciers.
