Less than one percent of glaciers surge. In the Karakoram, however, there is an extraordinarily high concentration of glaciers that do. In this week’s Video of the Week, see how the surging Shishpar Glacier in Pakistani Karakoram threatens human settlements.
French Resort in the Pyrenees Sparks Debate on the Transportation of Snow to Ski Slopes by Helicopter10 March 2020, by Audrey Ramming
Last month Luchon-Superbagnères, a resort in the French Pyrenees, used a helicopter to transport approximately fifty tons of snow to its bare, snowless slopes so that it could remain open during the height of tourist season. The blowback has triggered debate over best practices for ski resorts in the region.
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.
Climate change is rapidly thawing the world’s ice reserves. As glaciers recede, preserved artifacts are exposed, creating opportunity for archaeologists to delve into the secrets of past civilizations.
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.
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.
At least 13 people are dead in the mountains outside Cusco in a devastating glacier collapse and debris flow in a populated valley on a route well-known among trekkers to Machu Picchu.
Roundup: A New Glacier Surge Study, Three Decades of Caucasus Glacier-Debris Change, and Mining Expansion in Greenland2 March 2020, by Peter Deneen
In this week’s Roundup, read about a new study advancing understanding of glacier surges, research spanning nearly 30 years of debris cover change on Caucasus region glaciers, and how mining is poised to take advantage of glacier retreat in Greenland.
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.
Last month, fifty-year old Lewis Pugh swam one kilometer across a supraglacial lake atop Langhovde Glacier in East Antarctica. He wore nothing but a Speedo, a swim cap and goggles.
Researchers at the Climate Change Institute used a new high-resolution laser technology to analyze ice from the Colle Gnifetti Glacier in the Alps. This technology allowed the team to trace the history of Saharan dust events as well as the atmospheric conditions that promote them. They predict that climate change will intensify Saharan dust storms, worsening regional air quality and speeding glacial melt.
