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.
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 ...
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 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 ...
Alaska warmed by 4.3° F (2.4 °C), where melting glaciers contribute to sea level rise, and permafrost melt releases greenhouse gases. [3] Ninety percent of U.S. counties experienced a federal climate disaster between 2011 and 2021, with some having as many as 12 disasters during that time. [41]

Long-term mass balance records from Lemon Creek Glacier in Alaska show slightly declining mass balance with time. [105] The mean annual balance for this glacier was −0.23 m (0.75 ft) each year during the period of 1957 to 1976. Mean annual balance has been increasingly negatively averaging −1.04 m (3.4 ft) per year from 1990 to 2005.
