  • Asia’s High Glaciers Protect Communities from Drought

    A recent study in Nature by Hamish Pritchard, a glaciologist at Cambridge University and researcher for the British Antarctic Survey, shows that the high mountains of Asia, including the Himalayas, among other ranges, are being greatly affected by global warming. Global glacial volume is beginning to shrink, making it an international concern. Pritchard presents data that shows how much the glacier meltwater contributes to different regions within Asia during drought. If temperatures continue to rise, the surrounding areas will lose their protection from droughts and a constant source of water for food, agriculture and survival.

  • Hardangerjøkulen: The Real-Life Hoth is Disappearing

    Any Star Wars fan will recognize the remote ice planet Hoth, the location of some of the most iconic scenes from Episode V: The Empire Strikes Back, including the attack on the Rebel Alliance’s Echo Base by Imperial Walkers and Han Solo’s daring rescue of Luke Skywalker after his tauntaun was attacked by a wampa.…

  • Roundup: Volcanoes, Cryoseismology and Hydropower

    Roundup: Kamchatka, Cryoseismology and Bhutan   Activity in Kamchatka’s Glacier-Covered Volcanoes From KVERT: “The Kamchatka Volcanic Eruption Response Team (KVERT) monitors 30 active volcanoes of Kamchatka and six active volcanoes of Northern Kuriles [both in Russia]. Not all of these volcanoes had eruptions in historical time; however, they are potentially active and therefore are of…

  • Himalayan Region Considers Climatic Threat to Hydropower Future

    Glacial melt is threatening the Hindu Kush Himalayan region’s development of potential hydropower. A recent forum convened by the Kathmandu-based organization International Centre for Integrated Mountain Development (ICIMOD) highlighted the climatic and social challenges that accompany the establishment and sustainability of the region’s hydropower sector. The Sept. 1 event event, “Managing climate and social risks key…

  • Military intervention at Nepal’s fastest growing glacial lake

    Ten kilometres south of Mount Everest lies Nepal’s “fastest-growing glacier lake”— Imja Tsho. In March 2016, acting to mitigate potential threats the lake might pose to over 96,000 people downriver, the Nepalese Army began installing syphons to lower the water level by 10 feet (3 m). The army’s engineering department, commissioned by Nepal’s Department of Hydrology…

  • Roundup: Fungus, Hydropower, and Microbes

    Each week, we highlight three stories from the forefront of glacier news.   Fungal Biodiversity in the Periglacial Soil of Dosdè Glacier From The Journal of Basic Microbiology: “Periglacial areas are one of the least studied habitats on Earth, especially in terms of their fungal communities. In this work, both molecular and culture-dependent methods have…

    The Challenge of Sediment Management

    A new research study entitled “Ecosystem impacts of Alpine water intakes for hydropower: the challenge of sediment management” explores the effects of different hydropower capture techniques on human and ecosystem water needs. Rivers fed by glacial melt and snowmelt in Alpine regions serve as a critical resource for hydroelectric power production. However, the management systems…

    Roundup: Droughts and Floods in the Future

    15% Shrinkage for Tibet Glaciers “Glaciers on the Tibetan Plateau – the source of rivers such as the Brahmaputra – have shrunk by as much as 15 per cent, retreating by 8,000 square kilometres since 1980, according to a new Chinese government-backed study. The decades-long study conducted by the official Chinese Academy of Sciences (CAS)…

  • Roundup: Swiss Blankets and Data, Participation in Tajikistan

    Blankets covering Swiss glacier to halt ice melt is a temporary fix “From a distance, the Rhone glacier seems perfect, but when seen closely, the surface is covered with white blankets for slowing down the melting of the rapidly retreating ice. The dusty, white fleece covers a huge area near the glacier’s edge. But there…

  • Glacier Conference in Bhutan Promotes Collaboration

    A recent conference in Bumthang, Bhutan, titled “International Glacier Symposium: How much do we know about the glaciers of the high Himalayas?” presented data on glaciers there and in neighboring countries. It traced the implications of this work for hydropower development and environmental management across the Himalayan region and led to concrete plans for future…
