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

12 April 2017, by

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

22 February 2017, by

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

30 January 2017, by

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

5 January 2017, by

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

The Nooksack Indians, who live in northwest Washington near the border of Canada, are fighting to save local salmon populations through a variety of innovative measures. Several species of salmon reside in the Nooksack River, which is comprised of three main forks that drain a large portion of the Cascade Range into Bellingham Bay. The […]

Greenhouses bring hope to vulnerable mountain communities in Nepal

8 September 2016, by

Growing up in a Tibetan refugee camp in Nepal, I vividly remember how food insecurity impacted our everyday lives. Floods, droughts, and landslides would immediately determine what we ate. We ate high carb with little nutritional value when things got really bad. I dreaded those days. I looked forward to the rare days when we […]
