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 ...
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 ...
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.
Melting at the waterline is an important second order calving process as it undercuts the subaerial ice, leading to collapse. Other second order processes include tidal and seismic events, buoyant forces and melt water wedging. When calving occurs due to waterline melting, only the subaerial part of the glacier will calve, leaving a submerged ...
Ablation is the reverse of accumulation: it includes all the processes by which a glacier can lose mass. The main ablation process for most glaciers that are entirely land-based is melting; the heat that causes melting can come from sunlight, or ambient air, or from rain falling on the glacier, or from geothermal heat below the glacier bed.
Alaska's mighty Muldrow Glacier is moving 50 to 100 times faster than normal. It's a major surge. Large parts of the 39-mile-long "river of ice" are progressing some 30 to 60 feet per day, as ...
Exit Glacier is a glacier derived from the Harding Icefield in the Kenai Mountains of Alaska [1] and one of Kenai Fjords National Park's major attractions. It is one of the most accessible valley glaciers in Alaska and is a visible indicator of glacial recession due to climate change .
