Roundup: Climate Science and International Adaptation

8 June 2015, by

Integration of Glacier and Snow “Energy budget-based distributed modeling of snow and glacier melt runoff is essential in a hydrologic model to accurately describe hydrologic processes in cold regions and high-altitude catchments. We developed herein an integrated modeling system with an energy budget-based multilayer scheme for clean glaciers, a single-layer scheme for debris-covered glaciers, and […]

Photo Friday: Mount Adams

5 June 2015, by

Mount Adams, the second highest mountain in the U.S. state of Washington, is a potentially active volcano in the Cascade Range. Mount Adams was active from about 520,000 to about 1,000 years ago. During the past million years, it has generated considerable eruptive materials. Mount Adams is also home to 12 officially named glaciers. Most […]

Artist Reawakens Glacial Past In Central Park

4 June 2015, by

In the northeast corner of Central Park by the Harlem Meer, a large billboard hints at Manhattan’s icy past. The piece, commissioned as part of the Drifting in Daylight art exhibition celebrating the 35th anniversary of the Central Park Conservancy, was designed by Karyn Olivier. Olivier chose to depict a glacier that covered Manhattan 20,000 […]

New Cyanotoxins Surface in Polar Region

3 June 2015, by

Death by cyanobacteria-made microtoxins is not pleasant. The toxins damage the nervous system, especially anatoxin-a, also known as a Very Fast Death Factor. As the global temperature increases, concerns about the range of these toxins are growing. For the first time, anatoxin-a has been found as far north as the polar regions, according to a […]

Glaciers Shape Lives in Upper Hunza

2 June 2015, by

Glacier and river dynamics shaped irrigation systems and land use practices in Pakistan since the late 1700’s, according to a new paper by Sitara Parveen and his colleagues. These systems and practices can still be observed hundreds of years later, but they face severe challenges from glacier retreat. Upper Hunza is located in the western Karakoram, Pakistan. […]

Roundup: Bubbling Ice, Black Carbon, and Glacial Advance

1 June 2015, by

The sound of glaciers A new article in the scientific journal Geophysical Research Letters, titled Unusually loud ambient noise in tidewater glacier fjords: A signal of ice melt, tracks glacial melt by recording the sounds of the glaciers bubbling underwater in glacial bays. Check out videos of the unique sounds below, and read the article here.   […]

Photo Friday: Cryoconites and Glacier Tables

29 May 2015, by

Have you ever seen dark cavities on glaciers, which are also referred to as “cryoconites”? These holes, which can be meters deep,are created from debris on top of glaciers. Dark-colored debris, including soot, dust, and pollen, speed up the melting process of glacial ice as a consequence of their low reflectivity to incoming sunlight. In […]

Nepali Villagers Trapped Under Threat of Glacier Floods

28 May 2015, by

One month after the first of two major earthquakes in Nepal, 38 villages, 834 households and 4600 people continue to wait for substantial relief efforts and remain uncertain about the future. The first earthquake, which hit on April 25, severely damaged villages in Pharak, in the southern part of the Everest region in Nepal. When […]

Everest’s Glaciers in Peril

27 May 2015, by

Even the highest glaciers in the world will not escape the effects of climate change, according to a study published today (27 May) in  The Cryosphere, an open access journal of the European Geosciences Union (EGU). This study shows that the glaciers in the Everest region are very sensitive to warming, and will shrink massively […]

Glacial Retreat Encourages Seaweed Colonization

26 May 2015, by

Newly ice-free areas exposed by glacial retreat in Potter Cove, Antarctica, are being colonized by seaweed. With glaciers melting, the original white, mostly lifeless Antarctica is now becoming darker and lively with seaweed. These macroalgae not only produce oxygen for marine species through photosynthesis but also serve as the base of the marine food chain. […]

Roundup: Cyanobacteria, Glacier Calving and Glacier Fluctuations

25 May 2015, by

Arctic biocrust cyanobacterial communities “In the polar regions cyanobacteria are an important element of plant communities and represent the dominant group of primary producers. They commonly form thick highly diverse biological soil crusts that provide microhabitats for other organisms. Cyanobacteria are also producers of toxic secondary metabolites. The north-west coast of Spitsbergen, are able to […]

Photo Friday: Glacier Illuminated by Aurora

22 May 2015, by

This week’s photos feature the Athabasca Glacier in Alberta, Canada with Northern Lights in the background. Photographer Paul Zizka captured ice climber Stuart and Takeshi Tani hanging from the glacier when the Northern Light hits the sky. Paul Zizka is a professional mountain landscape and adventure photographer based in Banff, Alberta. He has a passion […]
