Die Ideen des Climate Engineering muten wie Science Fiction an: Spiegel, die Sonnenstrahlen umlenken, oder künstliche Wolken, die uns vor Erderwärmung schützen. Den Status des Utopischen scheint die Idee, dem Klimawandel mit technischen Hilfsmitteln entgegenzuwirken, nun zunehmend zu verlieren, wie Nachhaltigkeitsforscher Daniel Barben beobachtet. Er erforscht die Rolle von Climate Engineering in Wissenschaft, Politik und Zivilgesellschaft.
Die Nutzung von Biomasse für Energie und Rohmaterialien ist global auf dem Vormarsch, mit weitreichenden Auswirkungen auf die Ökosysteme. Auf Grund von Landnutzungskonkurrenzen könnte dies allerdings zu erheblichen Emissionen von Treibhausgasen führen. Mit einem neuen Modell, das ForscherInnen an der AAU nun in einem vom Wissenschaftsfonds FWF finanzierten Projekt entwickeln wollen, sollen diese Effekte nun berechnet werden.
In order to improve our understanding of climate change and to increase the predictability of future dynamics, it is necessary to gain a better understanding of the global carbon cycle. To date, little is known about the average time carbon is stored in biomass, before it passes back into atmosphere or soils (biomass turnover time), and the factors influencing this key parameter also remain largely unknown. Now, a new publication in Nature Geoscience shows that biomass turnover time in vegetation is halved as a result of human influence.
A new book, which is published just in time for the 3rd ISA Forum of Sociology 2016 in Vienna, comprehensively presents the current state-of-the-art of the Vienna School of Social Ecology. The conceptual repertoire of Social Ecology is exemplified by a cornucopia of empirical studies presenting exciting new research.
