Melting of mountain glaciers from 1994 to 2017 (6.1 trillion tonnes) constituted about 22% of Earth's ice loss during that period. [7]Excluding peripheral glaciers of ice sheets, the total cumulated global glacial losses over the 26 years from 1993 to 2018 were likely 5500 gigatons, or 210 gigatons per yr. [1]: 1275
Glaciers in the Juneau Icefield in southeastern Alaska are melting at a faster rate than previously thought and may reach an irreversible tipping point sooner than expected, according to a study ...
A National Park Service report on Alaska's glaciers noted glaciers within Alaska national parks shrank 8% between the 1950s and early 2000s and glacier-covered area across the state decreased by ...
The melting of Alaska's Juneau icefield, home to more than 1,000 glaciers, is accelerating. The snow covered area is now shrinking 4.6 times faster than it was in the 1980s, according to a new study.
The rapid retreat of the Cordilleran ice sheet is a focus of study by glaciologists seeking to understand the difference in patterns of melting in marine-terminating glaciers, glaciers whose margin extends into open water without seafloor contact, and land-terminating glaciers, with a land or seafloor margin, as scientists believe the western ...
Satellites have observed Columbia Glacier, one of the fastest-changing glaciers in the world withdraw into the Chugach Mountain Range in south-central Alaska. The glacier's speed of retreat at the terminus reached a maximum of nearly 30 meters (98 ft) per day in 2001, when it was discharging icebergs at approximately 7 cubic kilometers (1.7 cu ...
Scientists label their findings, which show glaciers could face rapid and irreversible retreat sooner than expected, as ‘very worrying’. Alaskan glacier melt has accelerated sharply in recent ...
A glacier (US: / ˈ ɡ l eɪ ʃ ər / GLAY-shər) or (UK: / ˈ ɡ l æ s i ə /) is a persistent body of dense ice that is constantly moving under its own weight; it forms where the accumulation of snow exceeds its ablation (melting and sublimation) over many years, often centuries.
