  • Photo Friday: Historic Images of Glaciers

    The National Snow and Ice Data Center (NSIDC) advances scientific research on the frozen areas of the Earth, known as the crysophere, and the climate that influences them. Founded in 1976, the center manages a data archive and educates the public about the cryosphere, including the world’s glaciers. Scientists of the NSIDC specialize in collecting…

  • How Arctic and Subarctic Peoples Perceive Climate Change

    Indigenous Arctic and Subarctic communities face social and environmental challenges that could impact their traditional knowledge systems and livelihoods, decreasing their adaptive capacity to climate change. In a paper featured in Ecology and Society, Nicole Herman-Mercer et al. discuss recent research that took place during an interdisciplinary project called Strategic Needs of Water on the…

  • Climate Change Increases Flood Risk in Peru

    The rising danger of glacial lake flooding in a warmer climate has important implications for humans and animal populations in Peru’s Cordillera Blanca. A recent study in CATENA by Adam Emmer et al. examined a large swath of nearly 900 high altitude Peruvian lakes in the mountainous Cordillera Blanca region, studying their susceptibility to outburst floods…

  • Krill Contribute to Ocean Carbon Storage in Patagonia

    Waters in the sub-Antarctic region of Chilean Patagonia are fed by glaciers in one of the largest freshwater systems on Earth, the North and South Patagonian Icefields. A recent study published in Marine Ecology Progress Series found that Euphasia vallentini, the most abundant species of krill in Chilean Patagonian waters, play a key role in…

  • Roundup: Glacier Retreat, Mountain Advocacy, and Precipitation

    Roundup:  Glacier Retreat, César Portocarrero and Precipitation   Centennial-Scale Glacier Retreat From Nature Geoscience: “The near-global retreat of glaciers over the last century provides some of the most iconic imagery for communicating the reality of anthropogenic climate change to the public. Surprisingly, however, there has not been a quantitative foundation for attributing the retreats to…

  • Photo Friday: The Glacial Alaska Range

    The Alaska Range is a narrow, 700-kilometer mountain range defined by rugged peaks and large U-shaped glacial valleys. The range lies in the southeast corridor of Alaska and is home to Denali, the tallest peak in North America. The Alaska range is part of the American Cordillera and possesses peaks only trumped by those in…

  • China’s Promotion of Everest Tourism

    Mount Everest is the highest peak in the world, sitting at 29,029 feet, roughly 5.5 miles above sea level. Though the south side of Everest is located in Nepal, about 100 miles from Kathmandu, the north side of Everest lies within the Tibet Autonomous Region and is governed by China. Earlier this year, China finished…

  • New Glacier App, A Finalist for Swiss App Awards

    A new glacier-themed app is a finalist for this year’s Swiss App Awards, an elite competition for mobile and app developers. The wgms Glacier App gives users access to the glacier database of the World Glacier Monitoring Service (WGMS) right from their smartphone, with over 3,700 glaciers loaded on it. Created by the WGMS at…

  • A New Technique to Study Seals Habitats in Alaska

    There are numerous harbor seals (Phoca vitulina) living in tidewater glacier fjords in Alaska. Harbor seals are covered with short, stiff, bristle-like hair. They reach five to six feet (1.7-1.9 m) in length and weigh up to 300 pounds (140 kg). Tidewater glaciers calve icebergs into the marine environment, which then serve as pupping and molting habitat for harbor seals…

  • Roundup: Remote Sensing, Black Carbon, and Skiing

    Roundup: Glacier Surface Motion, Black Carbon & Skiing   Remote Sensing Measures Glacier Surface Motion From ISPRS Journal of Photogrammetry and Remote Sensing: “For monitoring of glacier surface motion in pole and alpine areas, radar remote sensing is becoming a popular technology accounting for its specific advantages of being independent of weather conditions and sunlight… Synthetic aperture…
