  • A Glacier Makes a Cameo on ‘Madam Secretary’

    Glaciers made an unusual appearance on a primetime American television network last month: the television series Madam Secretary aired an episode whose plot involved a conflict between mining interests and an transnational public over the fate of a glacier in Chile. The show, on CBS, stars a fictional Secretary of State, Elizabeth McCord (played by…

  • Central Chile’s Valleys Irrigated by Glacial Waters

    Glaciers are an important factor for the success of agriculture in valleys in Chile. According to a recent study in the International Journal of Water Resources Management, the presence of glaciers at high elevation is one of the distinguishing factors that led to different degrees of agricultural development through irrigation among four valleys in Chile.…

  • Roundup: South American Glacial Research Efforts

    Glacial and Social Model of Chilean Irrigation “The model showed how external influences (globalization, climate, mountains) and complex adaptive systems (water conflicts, institutions and markets) influenced the evolution of irrigation development (the extension and emergence of novel properties) towards constructive (planned irrigation development) and destructive (climate change) futures… The model showed how external influences (globalization,…

  • Peru Faces Tensions Over Water

    Peru will face a “new normal” as greater agricultural and energy demands, population growth and climate change chip away at what is left of its glaciers, according to a recent article in the Yale Journal of International Affairs. Glacial retreat could ultimately lead to conflict in the country, the author found. “Peru offers an early…

  • Photo Friday: The Snow Star Festival

    In the Peruvian Andes, tens of thousands of pilgrims climb to the Sinakara valley to participate in an annual, multiple day celebration – Qoyllur Rit’i, or the Snow Star Festival. Held under a waning moon, the festivities are surrounded by the looming glaciers of Mount Qullqip’unqu. The Catholic festival celebrates not only Jesus, but also the mountain gods…

  • Roundup: Black Carbon, Winds, and Supraglacial Lakes

    Light-absorbing Particles in Peru “Glaciers in the tropical Andes have been rapidly losing mass since the 1970s. In addition to the documented increase in temperature, increases in light-absorbing particles deposited on glaciers could be contributing to the observed glacier loss. Here we report on measurements of lightabsorbing particles sampled from glaciers during three surveys in…

  • Climate Change Adaptation is Key to Water Security

    A significant research gap may be hindering community efforts to withstand climate-induced glacier melt, according to a new review from researcher Graham McDowell and his colleagues at McGill University. Understanding how to help communities adapt to the effects of glacier melt, which threatens water sources for communities worldwide, will require deeper assessments of existing projects,…

  • The Chameleon Glaciers

    Can you spot the glacier on the picture above? Not that easy… Glacier Noir is a debris-covered glacier located in the French Alps. Contrary to clean-ice glaciers which are shiny white or blue ice masses, debris-covered glaciers are ice masses with a layer of rock debris on the top which makes them look like their…

  • New Report Addresses Mountain Sustainability

    A major new report provides a thorough summary of research and an innovative discussion of development efforts in mountain regions. This report, titled ‘Mountains and Climate Change: A Global Concern,’ was published in December 2014 by the Mountain Partnership as part of the UN Sustainable Mountain Development Series. The Mountain Partnership is an international organization, dedicated to…

  • Photo Friday: Volcanoes in Ecuador

    Ecuador has a series of beautiful cone-shaped volcanoes along the Andes. This week, GlacierHub features three volcanoes from Ecuador: Cayambe, Chimborazo, and Tungurahua. Cayambe, locating in the Cordillera Central, is a Holocene compound volcano. Chimborazo, locating in the Cordillera Occidental, is the highest mountain in Ecuador. These two volcanoes are currently inactive. On the other…
