  • 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…

  • 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…

  • 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…

  • The Restlessness of Cotopaxi: A “Benevolent” Eruption

    On August 14, 2015, Ecuador’s glacier-capped Cotopaxi erupted for the first time since the 1940s. A billowing plume of ash rose early in the morning and grew through the day, reaching heights of over three miles. Two small eruptions rained ash on the southern outskirts of Quito, Ecuador’s capital 45 kilometers from the volcano. These…

  • Glacial Change in China’s Central Asia

    Though I lived in China’s Xinjiang Uyghur Autonomous Region for almost two years, it was only when I was in the heart of the Tian Shan mountains, my motorcycle meandering its way around fallen rock, sheep herds and horses, that I felt truly at home. Just a few hours outside of the city of Shihezi,…

  • Photo Friday: The Shrinking Patagonian Icefield

    Typically obscured by cloud cover and mist, it is difficult to study the glaciers of the Southern Patagonian Icefield from space. However, on April 29, May 1, and May 24, 2016, NASA satellites captured clear images of the glaciers. Compiled into striking mosaics, this data reveals a great deal about the shrinking icefield. For example,…
