  • Ion Concentrations Are Growing in Himalayan Lakes

    Dr. Franco Salerno and a team of Italian researchers conducted long-term field work in the Himalayan area, discovering a dramatic increase of ionic concentrations in glacial lakes. This increase may lead to some large and irreversible environmental effects, according to Salerno et al. A report detailing their findings was published in the journal of Environmental Science & Technology in July.

  • Roundup: Porcupine Glacier, Patterned Ground and Ciliates

    Roundup: Glacier Calving, Ciliates and the Alps   A calving event in Porcupine Glacier shows rapid retreat From the American Geophysical Union: “Porcupine Glacier is a 20 km long outlet glacier of an icefield in the Hoodoo Mountains of Northern British Columbia that terminates in an expanding proglacial lake. During 2016 the glacier had a 1.2…

From CBCNews: “It’s been the main source of water into Yukon’s Kluane Lake for centuries, but now the Slims River has suddenly slimmed down — to nothing. ‘What folks have noticed this spring is that…

  • Could Glacier Retreat Cause Seals to Wander?

    Though populations of harbor seals – the captivating species seen in almost every zoo – are stable in other areas of the world, they are seeing declines in southeastern Alaska. These particular seals use icebergs calved from nearby glaciers as a place to rest and breed, but changes in ice availability are affecting these behaviors, crucial…

  • If You Can’t Handle the Heat – Retreat

    Zachariæ Isstrøm, a large glacier in the northeast coast of Greenland, is in a state of accelerated retreat after it detached from an important sill. This shift has caused great instability for the glacier, according to a new study from Science Magazine. Recognizing 0.5 meters of possible sea level rise held within Zachariæ, and its acceleration expected to…

  • Climate Awareness Impedes Adaptation

    A lack of awareness about the threats posed by climate change in mountain communities in Tajikistan, Central Asia may endanger traditional modes of life and local economies, according to a study published recently in Climatic Change. If these communities do not begin adapting to climate change before temperatures pass the threshold, it will be too late to…

  • Perth Conference Highlights Glacier Retreat

    From 4-8 October 2015, researchers gathered to discuss and learn about the “Mountains of Our Future Earth.” This conference was held at the Centre for Mountain Studies (CMS) of the University of the Highlands and Islands in Perth, Scotland. It was organized by the CMS, together with the Mountain Research Initiative (MRI) and the Global Mountain…

  • Emerging Storms: Glacier Dust and Climate Change

    Dust storms are most often associated with hot deserts. However, there are 5 million square kilometres of cold arid land globally where significant dust storms have been reported. The combination of sparse vegetation and strong winds make some humid cold climate areas important dust sources. These can be found in Alaska, Canada, Greenland and Iceland…

  • PhotoFriday: When I am Laid in Earth

    The Lewis Glacier on Mount Kenya is one of the most surveyed tropical glaciers on Earth, and has been monitored and mapped regularly since 1934. In 2010, scientists found that the Lewis had shrunk by 23 percent in just the previous six years. The New York Times reports, “Our glaciers, we’re told, are disappearing freakishly fast, but fast for…

    Roundup: Fish in Patagonia, Film in Kashmir & Glacial Georgia

    One Fish, Two Fish: Black Southern Cod maintain a more diverse diet when near glacier meltwater areas “The black southern cod, Patagonotothen tessellata, is the most important notothenioid fish species in terms of abundance in southern Chilean Patagonia. However, studies on its trophic ecology are scarce. [This study assessed] the spatial variation in the diet of…
