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.
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.
Roundup: Bernie Wins First Glacier State Caucus, A Cryosphere Congressional Hearing, and Using Drones to Monitor Ice Flow24 February 2020, by Peter Deneen
In this week’s Roundup, the first glacier state to caucus in the 2020 Democratic presidential primary votes for Bernie Sanders, a congressional hearing focuses on the cryosphere, and unmanned aerial vehicles prove effective at ice flow monitoring.
Last week, French President Emmanuel Macron took the tram from the Alpine village of Chamonix up to Mont Blanc, Europe’s highest mountain, to pay homage to the legendary massif and reflect on the toll climate change is exacting on its great glacier, the Mer de Glace.
With 7,253 glaciers, Pakistan has more area under ice cover than any other country in the Hindu Kush Himalaya. With a new long term monitoring program, the nation will start observing them.
In this week’s Roundup, don’t miss the Climate Confession by planetary scientist Jeff Kargel, a tragic avalanche on a glaciated mountain in Turkey, and Prince William and Duchess Catherine’s prestigious new environment award; The Earthshot Prize.
