PREFACE by UNEP Climate change and its impacts on ecosystems and human well-being is one of the biggest challenges for mankind in the 21st century. Consistent trends in glacier changes are key indicators of ongoing climate change. Moreover, glaciers are an important component of the Earth’s hydrological system and the current accelerated melting has significant impacts on the environment and human activities, including natural hazards, water and energy supply, and global sea level rise. The long-term monitoring of glaciers is therefore a basic requirement for a scientific assessment of global glacier distribution, changes and related impacts. The standardized compilation and free dissemination of glacier data from all over the world, as undertaken by the World Glacier Monitoring Service and its predecessor organi- zations, is a major contribution in support of the work of organizations such as the United Nations Framework Convention on Climate Change (UNFCCC) and the Intergovernmen- tal Panel on Climate Change (IPCC). Glacier changes are also among the most prominent indicators used by the United Nations Environment Programme (UNEP) in assessment reports such as the Global Environment Outlook (GEO), the UNEP Yearbook series, or various editions of Global Environmental Alert Service (GEAS) bulletins. The tenth volume of the Fluctuations of Glaciers, covering the observation period be- tween 2005 and 2010, continues the series of detailed reports on measurements of glacier fluctuations reaching back to the late 19th century. It presents the latest compilation of scientific data on glacier changes in length, area, volume and mass from more than 800 glaciers around the globe. The report points out a continued overall ice loss at high rates which is consistent with ongoing global warming and corresponding energy fluxes to- wards the surface of the earth. The comprehensive Fluctuations of Glaciers reports represent the backbone of the scien- tific data compilation which comes with full meta-information on principal investigators, national correspondents, their sponsoring agencies and publication related to the reported data series. These five-yearly reports are complemented by the bi-annual Glacier Mass Balance Bulletin which presents the data in summary form for non-specialists through the use of graphic presentations rather than as purely numerical data. Together these series built the scientific background for concise and illustrated UNEP publications such as the Global Outlook for Ice and Snow (2007), Global Glacier Changes: facts and figures (2008), or Measuring Glacier Change in the Himalayas (2012) which were published for a wide range of audiences. UNEP commends the work of the WGMS and partners on this very important global issue and is grateful to all those who have supported and contributed to this long-term, global effort. Peter Gilruth, Dr. Director, Division of Early Warning and Assessment I II PREFACE by GCOS In 2012 the Global Climate Observing System (GCOS) celebrated its 20th anniversary. In 1992, when it was founded upon recommendation of the Second World Climate Confer- ence (WCC-2), certain fundamental climate records were already in place. The establish- ment of the GCOS was a response to the need to improve the understanding of the climate system observations in all its domains, i.e., atmosphere, ocean and land, in a coordinated and standardized way. Together the intergovernmental and international organizations most involved in observing the climate system, namely the WMO, the Intergovernmen- tal Oceanographic Organization (IOC) of UNESCO, the United Nations Environment Programme (UNEP) and the International Council for Science (ICSU) joined forces to establish the GCOS as a co-sponsored program coordinating a system of observing sys- tems for climate. A similar process followed in the terrestrial domain, as the need increased for a deeper understanding of global change in the Earth System. This led to the establishment of the Global Terrestrial Observing

Conditions will be encountered in mountains that have a significant effect on. military operations. Mountain operations require, among other things^ special equipment, special training and acclimatization, and a high decree of self-discipline if operations are to succeed. Mountains of military significance are generally characterized by rugged compartmented terrain witn\steep slopes and few natural or manmade lines of communication. Weather in these mountains is seasonal and reaches across the entireSspectrum from extreme cold, with ice and snow in most regions during me winter, to extreme heat in some regions during the summer. AlthoughNthese extremes of weather are important planning considerations, the variability of weather over a short period of time—and from locality to locahty within the confines of a small area—also significantly influences tactical operations. Historically, the focal point of mountain operations has been the battle to control the heights. Changes in weaponry and equipment have not altered this fact. In all but the most extreme conditions of terrain and weather, infantry, with its light equipment and mobility, remains the basic maneuver force in the mountains. With proper equipment and training, it is ideally suited for fighting the close-in battfe commonly associated with mountain warfare. Mechanized infantry can\also enter the mountain battle, but it must be prepared to dismount and conduct operations on foot.

  • Calving Processes and the Dynamics of Calving Glaciers ⁎ Douglas I
    Earth-Science Reviews 82 (2007) 143–179 www.elsevier.com/locate/earscirev Calving processes and the dynamics of calving glaciers ⁎ Douglas I. Benn a,b, , Charles R. Warren a, Ruth H. Mottram a a School of Geography and Geosciences, University of St Andrews, KY16 9AL, UK b The University Centre in Svalbard, PO Box 156, N-9171 Longyearbyen, Norway Received 26 October 2006; accepted 13 February 2007 Available online 27 February 2007 Abstract Calving of icebergs is an important component of mass loss from the polar ice sheets and glaciers in many parts of the world. Calving rates can increase dramatically in response to increases in velocity and/or retreat of the glacier margin, with important implications for sea level change. Despite their importance, calving and related dynamic processes are poorly represented in the current generation of ice sheet models. This is largely because understanding the ‘calving problem’ involves several other long-standing problems in glaciology, combined with the difficulties and dangers of field data collection. In this paper, we systematically review different aspects of the calving problem, and outline a new framework for representing calving processes in ice sheet models. We define a hierarchy of calving processes, to distinguish those that exert a fundamental control on the position of the ice margin from more localised processes responsible for individual calving events. The first-order control on calving is the strain rate arising from spatial variations in velocity (particularly sliding speed), which determines the location and depth of surface crevasses. Superimposed on this first-order process are second-order processes that can further erode the ice margin.

  • The Eiger Myth Compiled by Marco Bomio
    The Eiger Myth Compiled by Marco Bomio Compiled by Marco Bomio, 3818 Grindelwald 1 The Myth «If the wall can be done, then we will do it – or stay there!” This assertion by Edi Rainer and Willy Angerer proved tragically true for them both – they stayed there. The first attempt on the Eiger North Face in 1936 went down in history as the most infamous drama surrounding the North Face and those who tried to conquer it. Together with their German companions Andreas Hinterstoisser and Toni Kurz, the two Austrians perished in this wall notorious for its rockfalls and suddenly deteriorating weather. The gruesome image of Toni Kurz dangling in the rope went around the world. Two years later, Anderl Heckmair, Ludwig Vörg, Heinrich Harrer and Fritz Kasparek managed the first ascent of the 1800-metre-high face. 70 years later, local professional mountaineer Ueli Steck set a new record by climbing it in 2 hours and 47 minutes. 1.1 How the Eiger Myth was made In the public perception, its exposed north wall made the Eiger the embodiment of a perilous, difficult and unpredictable mountain. The persistence with which this image has been burnt into the collective memory is surprising yet explainable. The myth surrounding the Eiger North Face has its initial roots in the 1930s, a decade in which nine alpinists were killed in various attempts leading up to the successful first ascent in July 1938. From 1935 onwards, the climbing elite regarded the North Face as “the last problem in the Western Alps”. This fact alone drew the best climbers – mainly Germans, Austrians and Italians at the time – like a magnet to the Eiger.

  • Ilulissat Icefjord
    World Heritage Scanned Nomination File Name: 1149.pdf UNESCO Region: EUROPE AND NORTH AMERICA __________________________________________________________________________________________________ SITE NAME: Ilulissat Icefjord DATE OF INSCRIPTION: 7th July 2004 STATE PARTY: DENMARK CRITERIA: N (i) (iii) DECISION OF THE WORLD HERITAGE COMMITTEE: Excerpt from the Report of the 28th Session of the World Heritage Committee Criterion (i): The Ilulissat Icefjord is an outstanding example of a stage in the Earth’s history: the last ice age of the Quaternary Period. The ice-stream is one of the fastest (19m per day) and most active in the world. Its annual calving of over 35 cu. km of ice accounts for 10% of the production of all Greenland calf ice, more than any other glacier outside Antarctica. The glacier has been the object of scientific attention for 250 years and, along with its relative ease of accessibility, has significantly added to the understanding of ice-cap glaciology, climate change and related geomorphic processes. Criterion (iii): The combination of a huge ice sheet and a fast moving glacial ice-stream calving into a fjord covered by icebergs is a phenomenon only seen in Greenland and Antarctica. Ilulissat offers both scientists and visitors easy access for close view of the calving glacier front as it cascades down from the ice sheet and into the ice-choked fjord. The wild and highly scenic combination of rock, ice and sea, along with the dramatic sounds produced by the moving ice, combine to present a memorable natural spectacle. BRIEF DESCRIPTIONS Located on the west coast of Greenland, 250-km north of the Arctic Circle, Greenland’s Ilulissat Icefjord (40,240-ha) is the sea mouth of Sermeq Kujalleq, one of the few glaciers through which the Greenland ice cap reaches the sea.

  • Steep Rise of the Bernese Alps
    Corporate Communication Media release, 24 March 2017 EMBARGOED UNTIL FRIDAY 24 MARCH 2017 11:00H CET Steep rise of the Bernese Alps The striKing North Face of the Bernese Alps is the result of a steep rise of rocKs from the depths following a collision of two tectonic plates. This steep rise gives new insight into the final stage of mountain building and provides important knowledge with regard to active natural hazards and geothermal energy. The results from researchers at the University of Bern and ETH Zürich are being published in the «Scientific Reports» specialist journal. Mountains often emerge when two tectonic plates converge, where the denser oceanic plate subducts beneath the lighter continental plate into the earth’s mantle according to standard models. But what happens if two continental plates of the same density collide, as was the case in the area of the Central Alps during the collision between Africa and Europe? Geologists and geophysicists at the University of Bern and ETH Zürich examined this question. They constructed the 3D geometry of deformation structures through several years of surface analysis in the Bernese Alps. With the help of seismic tomography, similar to ultrasound examinations on people, they also gained additional insight into the deep structure of the earth’s crust and beyond down to depths of 400 km in the earth’s mantle. Viscous rocKs from the depths A reconstruction based on this data indicated that the European crust’s light, crystalline rocks cannot be subducted to very deep depths but are detached from the earth’s mantle in the lower earth’s crust and are consequently forced back up to the earth’s surface by buoyancy forces.
