European Geosciences Union annual assembly Vienna | Austria | 17–22 April 2016. Communication of uncertain information in earth sciences: data, models and visualization Information in the earth sciences is supplied to many end users, including regulators, policy makers and the general public. It is important that these end users understand the uncertainties in information so that they can make robust decisions. Much effort has been put into quantitative methods to describe the uncertainty in environmental information, but the outputs these generate (probabilities, confidence intervals etc.) are not always understood by the end user. Effective communication of uncertain information is an important challenge, and one which must be tackled collaboratively by earth scientists, statisticians, psychologists and others. In 2015 there was a successful session held at EGU to bring together scientists with a range of backgrounds to consider these issues. We believe that the area remains a lively and important one, and want to continue the discussion. We therefore invite you to consider submitting an abstract to the session.
