  Information - US5 Complex systems in geosciences: what is at stake

Event Information
Systems in geosciences are not only complicated (numerous interacting components), but complex. This means non trivial behaviours that make irrelevant our spontaneous linear reasonings either on the involved physics or on the management of our planet. For instance, to search for linear trends when trends are at all scales. Indeed, there is an embedded multiplicity of time-space scales resulting into intermittency, long range dependencies, non-gaussian statistics and overall an extreme variability. Applications in geosciences require quantum leaps in our ability to understand, simulate and tame this complexity, for instance to assess what is resilient and sustainable.

This session will illustrate what is presently at stake to better forecast, to take much more efficient decisions and to avoid disasters.
