Photo Friday: Chilean Volcanoes at Yellow Alert

3 April 2020, by

A couple of glacier-covered volcanoes in Chile, Nevados de Chillán and Villarrica are at yellow alert. The two volcanoes pose imminent threats to the communities living in their shadows.

Celebrating Women in the Cryosphere

26 March 2020, by

To celebrate Women’s History Month, we selected five of our favorite stories about women in the cryosphere: a Japanese woman who was the first woman to summit Mount Everest, a Qashqai activist who lost her life when Iran downed a Ukrainian Airliner earlier this year, an all-female Andean climbing team, a glacier-based educational program for young women, and AGU President and polar scientist Robin Bell.

Photo Friday: The Drygalski Ice Tongue

20 March 2020, by

Ice tongues are oddball characters of the cryosphere. At 43-miles long and up to 15 miles wide, Antarctica’s Drygalski Ice Tongue is the world’s largest. Despite facing the constant threat of licking by belligerent icebergs, it has managed to hang on for some 4,000 years.

Glacier Retreat Drives 400% Lake Expansion Southern Alps, New Zealand 1990-2020

19 March 2020, by

Glaciers of New Zealand’s Southern Alps have been losing ice volume since 1978, with an increasing rate in the last decade, resulting in a 400% expansion in the size of the glacial lakes fed by their meltwater.

Request for Submissions to the Global Report of Indigenous Knowledge and Local Knowledge on Climate Change 2020

17 March 2020, by

The value of indigenous knowledge and local knowledge to addressing anthropogenic climate change is being increasingly recognized and integrated. This call for submissions will help inform contributions to the IPCC Sixth Assessment Report.

Roundup: COVID-19 in Glacier Regions

16 March 2020, by

For this week’s Roundup we compiled the glacier regions affected by the novel coronavirus––including the Alps, Pyrenees, Caucasus, Karakoram, Himalaya, Greenland, and Cascades––where the dislocation of remote glacier communities cuts both ways. Expeditions to Mount Everest have been suspended.

Photo Friday: Piedmont Glacier ‘Like Cold Honey’

13 March 2020, by

Operation IceBridge may have ended, but nostalgia for personal images from the missions, like that of glaciologist Mike MacFerrin, keep it alive. His photo of a piedmont glacier in northeast Greenland reminds us of the fluid nature of ice.

Glacier Retreat Poses Threat to Beer Production

12 March 2020, by

Glacier retreat in Washington State’s Cascade Mountain Range may threaten the irrigation of hops crops in the Yakima Valley, where a large portion of the global supply of hops, a key ingredient in beer production, are grown.

Roundup: Thwaites Earthquakes, Peru Glacier Collapse Claims Lives, and an Alaskan Streamflow Study

9 March 2020, by

In this week’s Roundup, cryoseismologists say Thwaites Glacier’s retreat has it so close to the grounding like that it causes earthquakes when it calves, a catastrophic glacier collapse on a popular trekking route in Peru, and a study classifying Alaskan coastal streamflow patterns.

Thwaites Glacier in Antarctica is Now Causing Earthquakes

5 March 2020, by

Thwaites Glacier is one of Antarctica’s largest contributors to sea level rise. Its rate of loss has doubled in the past thirty years. Now glaciologists have discovered that it’s also creating earthquakes as it breaks up.

Video of the Week: Animation Shows Frequency of Antarctic Calving Events

4 March 2020, by

A new animation produced by a satellite imaging glaciologist shows three Antarctic calving events. The events, which occurred between 2017 and 2020, are indicative of the rapid retreat the Pine Island Glacier has experienced in recent years.

Photo Friday: Engabreen Glacier and Subglacial Laboratory

28 February 2020, by

Norway-based glaciologist and IPCC author Miriam Jackson takes us to her office, 200 meters below the ice of Engabreen Glacier, where scientists have been observing the Norway’s fastest retreating glacier since 1992.
