text: As they describe it, they explored "the potential skill of Coupled Model Intercomparison Project (CMIP5) decadal hindcasts from 9 GCMs and their ensembles over the period 1960-2010 from a hydrological perspective." And what did they thereby find? Quoting them again, they say that "the CMIP5 decadal simulations of rainfall exhibit very low skill when assessed across Australia and across a range of time-scales from yearly to longer which extend to the entire decade." And it is this finding that leads them to ultimately conclude that the current state of precipitation predictability "is not enough to drive impact models at decadal timescales and to influence policy and decision making."
