  • Using Film to Reduce Risk on Volcanoes

    For people to cope with environmental hazards, they need to understand threats – a key step that can lead to behavior change. A recent paper by Anna Hicks et al., published in the International Journal for Disaster Risk Reduction, describes the importance of communicating glacier hazards and other risks. The authors made videos and then assessed…

  • Learning from a Flood-Alarm System’s Fate

    A longer version of this post appeared in the April 2017 issue of EcoAmericas. When a flood from a mountain lake threatened to swamp the town of Carhuaz in the Peruvian Andes early one morning in April 2010, Víctor Rodríguez was the only person who knew. From his hut on a plain below the mountain,…

  • Flooding Glacial Lakes in Chile

    It is a peaceful experience to walk near the glacial lake near Colonia Glacier, one of several prominent glacier lakes in Patagonia, Chile. The breeze on the lake helps you relax as you look out on the distant glaciers. In such a tranquil setting, it is hard to imagine that a glacial lake outburst flood…

  • Local Communities Support Mountain Sustainability

    International capacity-building collaborations have been initiated to observe glaciers and develop action plans in the tropical Andes and Central Asia. A recent study titled “Glacier Monitoring and Capacity Building,” by Nussbaumer et al., highlights the importance of glaciers in the Andes and Central Asia for water management, hydropower planning and natural hazards.  The Andes and Central…

  • Rock Glaciers Help Protect Species in a Warmer Climate

    In a recent study by Duccio Tampucci et al., rock glaciers in the Italian Alps have been shown to host a wide variety of flora and fauna, supporting plant and arthropod species during temporary decadal periods of climatic warming. Certain species that thrive in cold conditions have been prone to high environmental stress during warm…

  • 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…

  • Ice-Spy: Declassified Satellite Images Measure Glacial Loss

    Since the 1960s, images from spy satellites have been replacing the use of planes for reconnaissance intelligence missions. Making the transition from planes to satellites was prompted by an infamous U-2 incident during the Cold War when U.S. pilot Francis Gary Powers’ U-2 spy plane was shot down in Soviet air space. Five days later,…

  • How Arctic and Subarctic Peoples Perceive Climate Change

    Indigenous Arctic and Subarctic communities face social and environmental challenges that could impact their traditional knowledge systems and livelihoods, decreasing their adaptive capacity to climate change. In a paper featured in Ecology and Society, Nicole Herman-Mercer et al. discuss recent research that took place during an interdisciplinary project called Strategic Needs of Water on the…

  • Mapping Landslides in the Himalayas

    Uttarakhand Himalaya in northwest India is a rural, mountain region that shares borders with Nepal and Tibet. Often referred to as “The Land of Gods” for its physical grandeur, Uttarakhand is surrounded by some of the world’s highest peaks and glaciers. However, such beauty comes at a price. The Uttarakhand area is prone to natural…

  • Iceberg Killing Fields Threaten Carbon Cycling

    Ryder Bay is helping mitigate impacts of climate change through removing carbon from the atmosphere to the ocean, where they can remain for centuries.
