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. It slowly shriveled from its peak size at the end of the Little Ice Age around 1850, but then that melt ...

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 Arctic sea ice minimum is the day in a given year when Arctic sea ice reaches its smallest extent, occurring at the end of the summer melting season, normally during September. Arctic Sea ice maximum is the day of a year when Arctic sea ice reaches its largest extent near the end of the Arctic cold season, normally during March. [14]
Retrogressive thaw slumps are slope failures due to abrupt thawing of ice-rich permafrost. [16] They have also been called ground-ice slumps, [17] thermocirques, [18] tundra mudflows, [19] retrogressive flow slides, [20] and bi-modal flows. [21] [13] These terms are no longer recommended by the National Snow and Ice Data Center (NSIDC). [21]
People in Alaska's capital have lived for more than a decade with periodic glacial dam outbursts like the one that destroyed at least two homes over the weekend. The water came from a side basin ...
Unlike the Laurentide Ice Sheet, which may have taken as many as eleven thousand years to fully melt, [3] the Cordilleran ice sheet melted very quickly, probably in four thousand years or less. [4] This rapid melting caused floods such as the overflow of Lake Missoula and shaped the topography of the fertile Inland Empire of Eastern Washington. [5]
Residents in Alaska's capital cleared out waterlogged homes Wednesday after a lake dammed by the picturesque Mendenhall Glacier gave way, causing the worst flooding in the city yet from what has ...
