  • 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…

  • Roundup: Green Development, Glacier Reduction, and Psychiatry

    Green Development in Patagonia From Project Muse: “This paper examines how Southern Andean Patagonia has been increasingly incorporated within networks of global capital since the 1990s. This remote region has become an iconic center for green development in Latin America. The article develops the argument that a regional territorial imaginary has facilitated this recent shift towards…

  • Two Glaciers in India Granted Personhood Status, Court Rules

    The Gangtori and Yamunotri glaciers in India were recently granted “living beings” status or personhood by the Uttarakhand state court in order to protect them, particularly from pollution and climate change. Located in the Himalayas, both glaciers are considered sacred by Hindus, the dominant religion in India, and are important pilgrimage sites. The glaciers also…

  • Roundup: Remote Sensing, Black Carbon, and Skiing

    Roundup: Glacier Surface Motion, Black Carbon & Skiing   Remote Sensing Measures Glacier Surface Motion From ISPRS Journal of Photogrammetry and Remote Sensing: “For monitoring of glacier surface motion in pole and alpine areas, radar remote sensing is becoming a popular technology accounting for its specific advantages of being independent of weather conditions and sunlight… Synthetic aperture…

  • Wildfires Melt Glaciers From a Distance

    Scientists have begun to trace a link between climate change, an increased number of wildfires and glacier melting.  Particles emitted by wildfires and then deposited on glaciers are thought to darken the ice’s surface, and may lead to more rapid melting. Natalie Kehrwald, a geologist from the United States Geological Survey (USGS), is currently studying…

  • Roundup: Antarctica and Greenland in peril, black carbon

    Ninety percent of the western Antarctic Peninsula’s glaciers are retreating From Carbon Brief: “These rivers of ice ooze their way down through the Peninsula’s rocky mountain range and into the ocean, powered by gravity and their own weight. But of the 674 glaciers on the Peninsula’s western side, almost 90% are retreating. This happens when their…

    The Question of Black Carbon

    Black carbon has only recently emerged as a known major contributor to climate change, especially for the Arctic. Formed by the incomplete combustion of fossil fuels, biofuels, and biomass, black carbon absorbs light more strongly than any other particulate matter, especially when deposited onto glaciers and snow cover. Here, it lowers their reflectivity, thereby absorbing…

    Roundup: Snowmaking Guns, Antarctic Ice, and Black Carbon

    Ski Resort’s New Snowmaking Guns  Describing a major ski resort in British Columbia, Canada: “De Jong says that after commercial operations end in July, four snowmaking guns and other infrastructure will be installed. It is expected to be used beginning in October. ‘If the pilot project is conclusive, this unique project will become a significant…

  • Roundup: Bubbling Ice, Black Carbon, and Glacial Advance

    The sound of glaciers A new article in the scientific journal Geophysical Research Letters, titled Unusually loud ambient noise in tidewater glacier fjords: A signal of ice melt, tracks glacial melt by recording the sounds of the glaciers bubbling underwater in glacial bays. Check out videos of the unique sounds below, and read the article here.  …

  • Photo Friday: Cryoconites and Glacier Tables

    Have you ever seen dark cavities on glaciers, which are also referred to as “cryoconites”? These holes, which can be meters deep,are created from debris on top of glaciers. Dark-colored debris, including soot, dust, and pollen, speed up the melting process of glacial ice as a consequence of their low reflectivity to incoming sunlight. In…
