Overcoming the impact of global, anthropogenic global changes on organisms and ecosystem will be among our the greatest challenge in the future. In this lecture students will learn the theoretical background of the mode of action of selected global changes as greenhouse effect (atmospheric CO2 concentrations, warming, extreme weather events), ozone hole vs. surface ozone and interactions between these factors. Following, methodological approaches for studying global change effects will be discussed. Then, a state-of-the art of global change ecology in terrestrial ecosystems and their feedback mechanisms will be given. At the end, a critical discussion with students about the presentation of this topic in media will be organised.
