JÜRGEN REINMÜLLER KLIMAVERHÄLTNISSE IN EXTREMEN HOCHGEBIRGEN DER ERDE Ergebnisse eines Sonderklimamessnetzes Diplomarbeit zur Erlangung des akademischen Grades „Magister der Naturwissenschaften“ an der Naturwissenschaftlichen Fakultät der Karl-Franzens-Universität Graz Betreuung durch: Ao. UNIV. PROF. DR. REINHOLD LAZAR Institut für Geographie und Raumforschung 2010 Eidesstattliche Erklärung 2 Eidesstattliche Erklärung Ich, Jürgen Reinmüller, erkläre hiermit, dass die vorliegende Diplomarbeit von mir selbst und ohne unerlaubte Beihilfe verfasst wurde. Die von mir benutzten Hilfsmittel sind im Literaturverzeichnis am Ende dieser Arbeit aufgelistet und wörtlich oder inhaltlich entnommene Stellen wurden als solche kenntlich gemacht. Admont, im März 2010 Jürgen Reinmüller Vorwort 3 Vorwort Die höchstgelegenen Bereiche der Hochgebirge der Erde weisen bis dato eine außerordentlich geringe Dichte an Klimastationen und damit ein Defizit an verfügbaren Klimadaten auf. Aussagen zu den thermischen Aspekten in den Gipfellagen extremer Hochgebirge jenseits der 6000 m Grenze konnten bis dato nur unbefriedigend erörtert werden. Als staatlich geprüfter Berg- und Schiführer und begeisterter Höhenbergsteiger liegen die beeindruckenden, hochgelegenen Gipfel seit Jahren in meinem Interessensbereich. Zudem sehe ich mich in meinem bergführerischen Arbeitsbereich zunehmend mit den Zeichen des aktuellen Klimawandels konfrontiert. Schmelzende Gletscher oder auftauender Permafrost stellen für Bergsteiger ein nicht unwesentliches Gefahrenpotential dar. Die durch das von Univ. Prof. Dr. Reinhold Lazar ins Leben gerufene Projekt HAMS.net (High Altitude Meteorological Station Network) gewonnenen Daten können künftig bei der Tourenplanung diverser Expeditionen miteinbezogen werden und stellen eine wichtige Grundlage für klimatologische Hochgebirgsforschung in großen Höhen dar. Ich selbst durfte dieses interessante Projekt durch den Data-Logger-Tausch am Aconcagua im Februar 2007 ein wenig unterstützen und werde dem Projekt auch in Zukunft mit Rat und Tat zur Seite stehen. -

We present the results of pollen analysis performed on an ice core recovered from Nevado Sajama, Bolivia, dated to 25 ka BP. Low pollen concentrations from 25 to 15 ka BP are consistent with the scenario of an expanded ice cap surrounded by sparse vegetation and cold conditions on the Altiplano during the Last Glacial Maximum. -
GRID-Arendal Annual Report 2018
29 and counting GRID-Arendal Annual Report 2018 Established in 1989 as a non-profit foundation under Norwegian law, GRID-Arendal’s mission is to create environmental knowledge that encourages positive change. We do this by organising and transforming available environmental data into credible, science-based information products, delivered through innovative communication tools and capacity building services targeting relevant stakeholders. GRID-Arendal works closely with United Nations Environment, other UN agencies and partners around the world to connect science to policy. Our goal is to shorten the distance between the emergence of new science and policy actions. We seek to influence thinking and action at the level of the global community on issues that require collective efforts because many problems cannot be solved at the national level alone. Acknowledgements GRID-Arendal would like to acknowledge the support of the Government of Norway and its other funders, partners and supporters.

A study area was selected to the northeastward of the Nevado Coropuna, the volcano currently covered by the largest tropical glacier on Earth. The current glacier extent, the moraines deposited in the past and paleoglaciers at their maximum extension have been mapped. The present and past Equilibrium Line Altitudes (ELA and paleoELA) have been reconstructed and the chlorine-36 ages have been calculated, for preliminary absolute dating of glacial and volcanic processes. -

Water Availability, Protected Areas, and Natural Resources in The
MOUNTAINRESEARCH AND DEVELOPMENT,VOL. 17, No. 3, 1997, PP. 229-238 WATERAVAILABILITY, PROTECTED AREAS, AND NATURAL RESOURCES INTHE ANDEAN DESERT ALTIPLANO BRUNO MESSERLI, MARTIN GROSJEAN, AND MATHIAS VUILLE Institute of Geography Universityof Berne, Hallerstrasse12 CH-3012 Berne, Switzerland ABSTRACTThe arid Andes between 18? and 30? South are located in the transition zone between the tropical and westerly circulation belts. Precipitation rates are lower than 150-200 mm/yr. Resultsfrom paleoclimatic and isotope hydrologic research suggest that modern recharge of the water resources in this area is very limited, or even below the level of detection. The groundwater resources of today were formed when precipitation rates were greater than at present by a factor of 2.5. Thus, water is a resource that is renewed extremely slowly,or is even non-renewable. The distribution of mountain protected areas along the 7,500 km Andean Cordilleraand the extent of the arid diagonal, the zone of extremely low precipitation that crosses from the western flank in southern Ecuador and Peru to the eastern flank in Argentina, are compared. This indicates the very low density of protected areas within the arid diagonal and the potential for endangerment of diversity in this highly sensitive, dynamic, and harsh environment. Scientific knowledge about the age and origin of water resourcesand maps of water protection zones are the basic elements required for decision making. This type of information should help to resolve the growing conflict between the users of water, especially between the expanding mining industry,conservationists, and local communities concerned with the integrity of the fragile mountain ecosystems.
