International Expert Group on Earth System Preservation : ウィキペディア英語版 | International Expert Group on Earth System Preservation The Institute for Earth System Preservation (IESP) is a global network of scientists, decision makers, and members from governmental and non-governmental organizations. Its purpose is to contribute to advances in Earth system science through thematic-based conferences, workshops, seminars, lectures and publications.〔http://www.iesp.de/index.php?id=1050〕 It serves as a liaison between experts, decision makers and the public to promote a mutually, beneficial exchange and to provide access to current scientific knowledge. Its activities contribute to policy debate by providing a common platform for discussion on sustainable development of ecosystems, economic and societal systems and their interrelationships. The IESP network has more than 50 international members from the fields of sustainability research, energy engineering and environmental sciences, natural resource technology, environmental engineering, climate dynamics, risk assessment, industrial ecology, political sciences, economics, and more. The network works with organizational staff located on the campus of the Technical University Munich in Garching, Germany.〔http://www.tum-ias.de〕 == Research and conferences == The thematic-based activities of the IESP focus mainly on advances in Earth system science. The Earth system is the sum of the planet’s interacting physical, chemical and biological processes.〔Schellnhuber, H.J. (1999): ‘Earth system’ analysis and the second Copernican revolution. Nature, 402, C19-C28〕〔Claussen, M., Mysak, L.A., Weaver, A.J., Crucifix, M., Fichefet, T., Loutre M.-F., Weber, S.L., Alcamo, J., Alexeev, V.A., Berger, A., Calov, R., Gannopolski, A., Goosse, H., Lohmann, G., Lunkeit, F., Mokhov, I.I., Petoukhov, V., Stone, P., Wang, Z. (2002): Earth system models of intermediate complexity:closing the gap in the spectrum of climate system models. Climate Dynamics 18, 579-586〕 Land, oceans, atmosphere and the frozen poles are all part of the system, as well as the grand natural cycles (carbon cycle, nitrogen cycle, phosphorus cycle and sulfur cycle). The Earth system includes the movement of the water between sea, sky, rivers and the movement of the tectonic plates. Living things and their activities are also an integral part of the system, including humans. But as human population and societies have grown, the reach and impact of our actions has increased as well, causing environmental changes in many ways, for example global warming. Thus humans are changing the Earth system itself, deeply affecting its dynamic. Therefore one of the most important questions for the experts of the IESP is how to keep the Earth system resilient and provide good living-conditions on earth for future generations.
