  • Roundup: Dust, Collapse, and Fire

    Dust Distribution in East Asia From Journal of Meteorological Research: “East Asian dust (EAD) exerts considerable impacts on the energy balance and climate/climate change of the earth system through its influence on solar and terrestrial radiation, cloud properties, and precipitation efficiency. Providing an accurate description of the life cycle and climate effects of EAD is…

  • 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: New Bacteria, Poetic Shasta, and Glacial Melt

    New Bacteria Discovered at Tibetan Glacier From Microbiology Society: “A cold-tolerant, translucent, yellow-pigmented, Gram-stain-positive, non-motile, rod-shaped bacteria was isolated from snow of the Zadang Glacier on the Tibetan Plateau, PR China. 16S rRNA gene sequence similarity analysis indicated that the isolate was closely related to Conyzicola lurida KCTC 29231T and Leifsonia psychrotolerans DSM 22824T at a level of 97.72 and 97.49 %, respectively.…

  • Photo Friday: Monitoring Chile’s Volcanoes

    Currently, three volcanoes in Chile are restless, according to the Servicio Nacional de Geología y Minería. A “class yellow” status for these glacier-covered peaks means elevated seismic activity and higher potential for eruption. The ice caps on these giants mean that an eruption could spur Jökulhlaups, glacial outburst floods that can be extremely dangerous, such as in…

  • Roundup: Antarctic Coral, Laser Ultrasound, and Totten Glacier

    Ecology of Antarctic Coral From Science Direct: “Antarctic ecosystems present highly marked seasonal patterns in energy input, which in turn determines the biology and ecology of marine invertebrate species. The pennatulid Malacobelemnon daytoni, is one of the most abundant species in Potter Cove, Antarctica. Its biochemical compositions were studied over a year-round period. The profiles suggest…

  • IPCC Announces Details of a Report Chapter on High Mountains

    On 17 August, the Intergovernmental Panel on Climate Change (IPCC) announced the list of experts it has invited to work on a major document, the Special Report on the Ocean and Cryosphere in a Changing Climate (SROCC). Hans Poertner, the co-chair of IPCC Working Group II, underscored the importance of this report. In a statement issued…

  • National Climate Assessment Report Under Review by Trump Administration

    The Trump administration reviews a 545-page draft report about the causes and impacts of global warming including the imminent threat of glacial retreat, which is part of the National Climate Assessment.

  • Roundup: Climate Change and Poetic Geology

    Trump Administration Disbands Climate Advisory Committee From Nature: “The advisory group’s charter expired on 20 August, and Trump administration officials informed members late last week that it would not be renewed. ‘It really makes me worried and deeply sad,’ says Richard Moss, a climate scientist at the University of Maryland in College Park and co-chair…

  • The Restlessness of Cotopaxi: A “Benevolent” Eruption

    On August 14, 2015, Ecuador’s glacier-capped Cotopaxi erupted for the first time since the 1940s. A billowing plume of ash rose early in the morning and grew through the day, reaching heights of over three miles. Two small eruptions rained ash on the southern outskirts of Quito, Ecuador’s capital 45 kilometers from the volcano. These…

  • The Pascua-Lama Mining Project Threatens Glaciers

    Fabiana Li, an associate professor in the Department of Anthropology at the University of Manitoba, brings new insight to a long-standing conflict over a South American mining project in her recently published article “Moving Glaciers: Remaking Nature and Mineral Extraction” on Sage Journals. Li’s article investigates the controversial Pascua-Lama mining project, located on the border…
