Climate modelling is an extremely powerful tool for the quantification of earth system dynamics, allowing the reconstruction of past environments and projections of future change. In this workshop, an introduction to and discussion of the development and application of models at different spatial and temporal scales will be discussed and illustrated. Christoph Raible is a senior scientist of Climate and Environmental Physics at the University of Bern. In this workshop, he will share his broad experience of the field of climate modelling and its application to climates of the past, present and future.
