These differences between projected and observed trends in rainfall seem to raise serious questions about the ability of the models to predict changes in rainfall — though Iâ $ ™ d be interested in CSIRO views, especially on whether it is appropriate to use successive 11 - year averages as measures of outcome and, if it is not, how the relationship between projections and outcome should be monitored.
