    Glacial Retreat and Water Impacts Around the World

    A new study recently published in Nature Climate Change examines the impacts of climate change on water availability in glacierized basins.

  • Local Communities Support Reforestation in the Peruvian Andes

    Human activities have drastically reduced the natural habitats of Polylepis, a rare genus of tree species that dominates the high altitude forests of the Andes and can grow from an elevation of 3000 meters close to the glacier line, at approximately 5000 meters above sea level. A recent analysis by Beatriz Fuentealba and Steven Sevillano of reforestation efforts centered on Polylepis in Ancash, Peru, has highlighted the importance of local communities for the successful implementation of these activities.

  • These Indigenous Communities are Models for How to Adapt to Climate Change

    When the poisoned river ran red with heavy metals, people from nearby communities didn’t believe at first that climate change was to blame. In remote mountain villages around the Rio Negro, adaptation efforts took a curious and innovative form.

  • Roundup: Climate justice, Impacts of Glacial Retreat, and Sediments

    In this week’s roundup, we look at an indigenous Peruvian farmer’s fight for climate justice, impacts of glacial retreat in the tropical Andes, and increasing sediment delivery to global oceans from Greenland’s ice sheets.

  • 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…
