This session explores the linkages between climate extremes, biosphere and societal dynamics. I.e. emphasis is laid on 1) what impacts are caused by climate extremes on various aspects of the biosphere (incl. e.g. productivity, biogeochemical cycling, biodiversity) and society (e.g. political, economic aspects), and 2) which feedbacks exist amplifying or moderating the intensity, duration or extent of climate extremes. Empirical, theoretical and modelling studies from local to global scale are all highly welcome.
