Convenors: Douglas Maraun - University of Graz, Austria; Marjolijn Haasnoot - DELTARES, The Netherlands

Session description : Climate projections are uncertain because of unknown future forcings, model inadequacies and irreducible internal variability. This holds in particular for extreme events, tipping points and more generally low likelihood high impact events. Their occurrence may be plausible, we may even know that they are really possible, and we may have strong evidence that they become more likely with higher global warming. But these events are often not well captured by climate models and the associated uncertainties might be difficult to quantify. Despite uncertainty - or because of uncertainty – considering such events is relevant for adaptation decision making because of the high impacts and potentially transformative adaptation measures which take time to plan and implement. In this session, we aim to discuss uncertainties in climate projections, various approaches used to represent these uncertainties and the relevance and approaches to deal with them in adaptation decision making.
