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 ...
Sea ice loss not only enhances warming in the Arctic but also adds to global temperature increase through the ice-albedo feedback. Permafrost thaw results in emissions of CO 2 and methane that are comparable to those of major countries. Greenland melting is a significant contributor to global sea level rise. If the warming exceeds - or ...
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 ...
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 Arctic Ocean is the mass of water positioned approximately above latitude 65° N. Arctic Sea Ice refers to the area of the Arctic Ocean covered by ice. 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.
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
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 ...
The date of annual melt is of great interest as a potential indicator of climate change. In order to determine whether the earlier disappearance of spring snow cover in northern Alaska is related to global warming versus an appearance of a more natural, continual cycle of the climate, further study and monitoring is necessary.
