  • Cooperation in the Face of Glacier Retreat: The Plants’ Story

    As new areas become exposed as glaciers retreat, plants begin to colonize them. Do the different species support or compete with one another? A recent study published in the Journal of Vegetation examines this interaction in southern Norway.

  • Let it Snow… and Save a Glacier

    News about shrinking glaciers is not uncommon, but have you ever heard of regrowing one artificially? That is exactly what a team of researchers intends to do: use snow machines, also known as Schneekanonen (snow-cannons) in German, to save Morteratsch Glacier in the Swiss Alps. Felix Keller, a glaciologist at the Academia Engiadina in Switzerland,…

  • Glacier Retreat Exposes New Breeding Ground for Kelp Gulls in Antarctica

    Glacier retreat caused by anthropogenic climate change is often in the news because of its impacts on sea level rise and shrinking habitats. However, a recent study published by Lee et al. in the Journal of Ethology has found that glacier retreat on King George Island could have a positive impact on kelp gulls, exposing…

  • BREAKING: Ryan Zinke Confirmed as Interior Secretary, Talks Glacier Retreat

    It’s official. The Senate voted today to confirm Rep. Ryan Zinke (R–MT) as the nation’s next Secretary of the Interior. The strong majority confirmation vote of 68-31 gives Zinke, a Westerner and fourth–generation Montanan, commanding power over the nation’s most prized public lands and wildlife as well as 70,000 employees, 280,000 volunteers, and a $12 billion annual…

  • Research Shows How Climate Change Drives Glacier Retreat

    Shrinking glaciers are oft-cited examples of the effects of anthropogenic climate change, providing dramatic imagery in different parts of the world. However, this has mostly been based on global aggregates of glacier extent. Differing opinions also exist about the best way to measure glacial change all over the world.  A recent study by Roe et…

  • 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…

  • Roundup: River Outlets, Plant Habitats, and Village Partners

    Roundup: Canadian River Vanishes, Plants in the Himalayas and Pakistan’s Villages Glacier retreat in Canada causes Yukon river to vanish. 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…
