Plants play a key role in the climate system by influencing the hydrological cycle and the carbon cycle, as well as affecting the Earths albedo. Moreover, changes in climate may result in adaptive responses in vegetation that can feed back on the climate system. The processes that are most dominantly affected depend on the time scale of interest. For example, at the time scale of several minutes, plants may influence the formation of shallow cumulus clouds, while evolutionary changes in plant functional traits, such as rooting depth, may influence mineral weathering rates and subsequent atmospheric CO2 levels at geological time scales. This session aims to bring together scientists from different fields, including palaeoecology, ecophysiology, geology and climate science, and exchange knowledge on the different processes through which plants interact with the climate system across time scales. We welcome submissions that include analyses of palaeo data and modern (field) data, experiments, and modelling, specifically on topics that span multiple time scales.
