  • Water Access and Glacial Recession in Peru

    A new paper published in the journal Global and Planetary Change examines the transformation of glacierized hydro-social systems in Peru through the lens of biophysical and social processes.

  • Roundup: Glacier Shrinkage, Inventory and Reconstruction

    Glacier Shrinkage affecting water supply, glacier inventory in the Chilean Andes, and glacier reconstruction.

  • Climate, Economy, Family: Migration in the Bolivian Andes

    High in the Bolivian Andes, the pace of glacial retreat is accelerating, which may significantly decrease the amount of glacial meltwater available to streams and aquifers critical to farming communities in the region’s river basins. In addition to the long-term threat posed by glacial retreat, these communities are also threatened by economic uncertainty and climatic variability.…

  • Roundup: Carbon Sinks, Serpentine Syndrome and Migration Dynamics

    Roundup: Carbon, Serpentine, and Migration   Dwindling Glaciers Lead to Potential Carbon Sinks From PLOS ONE: “Current glacier retreat makes vast mountain ranges available for vegetation establishment and growth. As a result, carbon (C) is accumulated in the soil, in a negative feedback to climate change. Little is known about the effective C budget of…

  • 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…

  • Roundup: Cold War waste, glacier retreat, and “glacier quakes”

    Cold War Waste Buried Beneath Melting Greenland Ice From Scientific American: “When the U.S. military abandoned Camp Century, a complex of tunnels dug into the ice of northwest Greenland, in the mid-1960s, they left behind thousands of tons of waste, including hazardous radioactive and chemical materials. They expected the detritus would be safely entombed in…

  • In Argentina, Tensions Remain Between Mining and Glacier Protection

    A recent article “Defending Glaciers in Argentina” in the journal Peace Review, written by Asmaa N. Khadim, explores the history of one of the world’s largest mining companies, Barrick Gold Corporation, and its conflict with Argentina’s environmental protectors. Many of its mining projects are in proximity to glaciers, which are a crucial water source for…

  • 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,…
