  • Wildfires in Peru Could Increase Glacial Melt

    A recent study by John All et al., “Fire Response to Local Climate Variability,” investigates whether or not human interference in the fire regime of Huascarán National Park in Peru was the primary cause of an increase in fire activity in the park. The fire activity, whether caused by humans or climate variability, was poorly…

  • Using Drones to Study Glaciers

    A new study shows how Unmanned Aerial Vehicles (UAVs) can be used to track high-altitude glacier change in a relatively cheap, safe and accurate way.

  • Photo Friday: The Melting Andean Glaciers

    In South America, the tropical glaciers of the Andes have been shrinking at an alarming rate, leaving the local communities at risk of losing an important water source. In Bolivia, for example, an Andean glacier known as the Chacaltaya Glacier disappeared completely in 2009, cutting off a valuable water resource to the nearby city of…

  • Andean Farmer Demands Climate Justice in Germany

    In the Cordillera Blanca Mountains of the Peruvian Andes, glacier retreat caused by climate change has led to an increased risk of flooding for residents living below. Saúl Luciano Lliuya, a farmer and mountain guide who faces the imminent threat of losing his house in a massive flood, argues that large polluters are to blame.…

  • Roundup: Sediments, Swamps and Sea Levels

    Roundup: High Arctic, Peru, and Global Seas   Suspended Sediment in a High-Arctic River From Science of The Total Environment: “Quantifying fluxes [the action of flowing] of water, sediment and dissolved compounds through Arctic rivers is important for linking the glacial, terrestrial and marine ecosystems and to quantify the impact of a warming climate… This…

  • 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…

  • The Andes Challenge: Extreme Sports, Tourism and Science in Peru

    Four extreme athletes gathered before dawn on August 28 at a glacier in Peru to start a 170 kilometer race. Setting off from the foot of Mount Vallunaraju in the Cordillera Blanca range, they ran up to its summit at 5625 meters and down to the Llaca valley. They then alternated cycling and running, passing…

  • Photo Friday: The Cordillera Blanca of Peru

    I traveled recently to the Cordillera Blanca, the mountain range in Peru with the largest concentration of glaciers in the world’s tropics. The Peruvian National Institute for Research in Glaciers and Mountain Ecosystems, INAIGEM, invited me to participate in a forum, and helped me visit several rural communities. I’ve written other posts about the forum,…

  • New Study Offers Window into Glacial Lake Outburst Floods

    A recent geological study has shed some light on the cause of a major, yet elusive destructive natural hazard triggered by failed natural dams holding back glacial lakes. The findings show how previously unrecognized factors like thinning glacier ice and moisture levels in the ground surrounding a lake can determine the size and frequency of Glacier Lake…

  • Traces of tourism at the Peru glacier are more than footprints

    Pastoruri Glacier in Peru’s Cordillera Blanca has gone through many different cycles. In the 1980s and well into the 1990s, in was a prime spot for tourism. Easily accessible in spite of its altitude above 5,000 meters, groups of skiers, backpackers, and high school spring breakers flocked to the icefields. In 2001, the glacier at…
