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 ...
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 ...
Hog Butte Fire, Alaska, June 2022 Sign thanking firefighters, Deshka Landing Fire, 2019. In August 2016, the Environmental Protection Agency reported that "[o]ver the past 60 years, most of the state has warmed three degrees (F) on average and six degrees during winter" [1] As a result of this temperature increase, the EPA noted that "Arctic sea ice is retreating, shores are eroding, glaciers ...
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.
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.
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 ...
Isostatic rebound in response to glacier retreat (unloading), increase in local salinity (i.e., δ18Osw), have been attributed to increased volcanic activity at the onset of Bølling–Allerød, are associated with the interval of intense volcanic activity, hinting at an interaction between climate and volcanism - enhanced short-term melting of glaciers, possibly via albedo changes from ...
The snow of glaciers in the central Andes melted rapidly due to a heatwave, [14] increasing the proportion of darker-coloured mountains. With alpine glacier volume in decline, much of the environment is affected. These black particles are recognized for their propensity to change the albedo – or reflectance – of a glacier.
