  • Driving the Dalton: A Tour of North Slope Glacial History

    The only road in the United States that crosses the Arctic Circle is the Dalton Highway: a remote, potholed, perilous path that begins north of Fairbanks and terminates at the Arctic Ocean. For some, driving the Dalton is a bold, lonely adventure, and for others, it’s just a long commute to work. Molly Timm, field…

  • An Interview on Patagonian Imaginaries

    A recent paper in the Journal of Latin American Geography, “The Patagonian Imaginary: Natural Resources and Global Capitalism at the Far End of the World,” analyzes the construction of southern Andean Patagonia as an “ecoregion,” a label that has come to dominate the representation of the glaciated territory of Chile and Argentina. Through this representation, resource…

  • Meet the Writers of GlacierHub, 2016/2017 Edition

    Here at Glacierhub we have a team of passionate writers and scientific explorers working hard to bring you original reporting on glaciers and the global impacts of climate change. With funding support from Columbia University’s Earth Institute and Center for Research on Environmental Decisions, our writers cover stories about communities living near glaciers and the challenges…

  • Roundup: Antarctic Coral, Laser Ultrasound, and Totten Glacier

    Ecology of Antarctic Coral From Science Direct: “Antarctic ecosystems present highly marked seasonal patterns in energy input, which in turn determines the biology and ecology of marine invertebrate species. The pennatulid Malacobelemnon daytoni, is one of the most abundant species in Potter Cove, Antarctica. Its biochemical compositions were studied over a year-round period. The profiles suggest…

  • Photo Friday: Lake Issyk Kul

    Located high in Central Asia’s Tian Shan Mountains, Issyk Kul is one of the world’s largest alpine lakes. Though Issyk Kul literally means “warm lake” in the Kyrgyz language, the crystalline waters vary in surface temperature from as high as 73 degrees Fahrenheit in July to as low as 36 degrees Fahrenheit in January. Still, warmth is relative, and…

  • 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…

  • IPCC Announces Details of a Report Chapter on High Mountains

    On 17 August, the Intergovernmental Panel on Climate Change (IPCC) announced the list of experts it has invited to work on a major document, the Special Report on the Ocean and Cryosphere in a Changing Climate (SROCC). Hans Poertner, the co-chair of IPCC Working Group II, underscored the importance of this report. In a statement issued…

  • National Climate Assessment Report Under Review by Trump Administration

    The Trump administration reviews a 545-page draft report about the causes and impacts of global warming including the imminent threat of glacial retreat, which is part of the National Climate Assessment.

  • Roundup: Climate Change and Poetic Geology

    Trump Administration Disbands Climate Advisory Committee From Nature: “The advisory group’s charter expired on 20 August, and Trump administration officials informed members late last week that it would not be renewed. ‘It really makes me worried and deeply sad,’ says Richard Moss, a climate scientist at the University of Maryland in College Park and co-chair…

  • Photo Friday: Air Bubbles in Glacial Ice

    Glacial ice can range in age from several hundred to several thousands of years old. In order to study long-term climate records, scientists drill and extract ice cores from glaciers and ice sheets. The ice cores contain information about past climate, giving scientists the ability to learn about the evolution of ice and past climates. Trapped air bubbles contain…
