  • Major Report Stresses the Importance of Glaciers in a Global Context

    In September, a new report titled “Well Under 2 Degrees Celsius” was produced by the Committee to Prevent Extreme Climate Change, a global think-tank group made up of scientists, policy makers and military experts.

  • Narwhals in Scoresby Sound

    A version of this post originally appeared on narwhals2017.com. It has been lightly edited and republished with permission by the researchers of the Greenland Institute of Natural Resources (Pinngortitaleriffik). In 2010, Mads Peter Heide-Jørgensen and his colleague Hans Christian Schmidt discovered that Hjørnedal in Scoresby Sound in the Greenland Sea was an ideal place for the live capturing of…

  • Roundup: New Bacteria, Poetic Shasta, and Glacial Melt

    New Bacteria Discovered at Tibetan Glacier From Microbiology Society: “A cold-tolerant, translucent, yellow-pigmented, Gram-stain-positive, non-motile, rod-shaped bacteria was isolated from snow of the Zadang Glacier on the Tibetan Plateau, PR China. 16S rRNA gene sequence similarity analysis indicated that the isolate was closely related to Conyzicola lurida KCTC 29231T and Leifsonia psychrotolerans DSM 22824T at a level of 97.72 and 97.49 %, respectively.…

  • Arctic Field Science: An Unruly Harmony

    It’s 9 p.m. on my 26th birthday, and I’m standing outside a trailer in the middle of the Alaskan tundra. The trailer is my workplace for the summer, and my labmates and I are waving signs— mine reads “You are Alaska”— and cheering for the runners sprinting past us, in the final meters of an…

  • Putin Visits Arctic Glaciers

    President Vladimir Putin recently visited Russia’s Franz Josef Land archipelago in March, where he was briefed about scientific research taking place at the glaciers. He even grabbed an ice pick and carved out a sample from one of the glaciers. The main purpose of the trip was to inspect the progress of a project to…

  • Roundup: Glacier Park, Lahars, and Glacial Ecosystems

    Roundup: Glacier Park, Lahars and Ecosystems Glacier National Park Embraces Sustainability From Xanterra: “Just 150 years ago, 150 glaciers graced these spectacular alpine summits. Only 25 remain large enough today to be considered ‘functional,’ say scientists who expect the park’s glaciers to vanish by 2030, with many disappearing before that. People heeding the advice to visit…

  • Glaciers Act as Pollutant Transporters in the Arctic

    When people think of the Arctic, they often think of polar bears on melting sea ice, not of an area contaminated by pollutants. However, according to an article by Maria Papale et al. in the Marine Pollution Bulletin, findings of polychlorinated biphenyls (PCBs) in the Arctic demonstrate that ice can be a major transporter of…

  • Glaciers Serve as Radioactive Storage, Study Finds

    The icy surfaces of glaciers are punctured with cryoconites – small, cylindrical holes filled with meltwater, with thin films of mineral and organic dust, microorganisms, and other particles at the bottom of the hole. New research conducted by Polish scientists reveals that cryoconites also contain a thin film of extremely radioactive material. The study confirms…

  • Ice loss surpasses poaching as largest threat to Barents Sea polar bear

    Prior to the 1970s, hunting decimated polar bear populations across the Arctic. The international community has made strides in protecting the iconic species from over-harvesting through conservation agreements, which have helped the species start to recover. However, a review paper published in Polar Research in July suggests that the road to recovery is far from…

  • “Red snow” algae accelerating glacier melt in the Arctic

    Scientists have discovered a troubling new characteristic of the tough algae that grow on the surface of Arctic glaciers: not only do they turn the glacier surfaces red, they accelerate the melting of the ice. Across the Arctic, from Greenland to Sweden, glacier ice is turning red in what has been termed “watermelon snow.” The…
