Box 10.1, Figure 2: Analysis of inter-model consistency in regional precipitation change. Regions are classified as showing either agreement on increase with an average change of greater than 20% (‘Large increase’), agreement on increase with an average change between 5 and 20% (‘Small increase’), agreement on a change between -5 and +5% or agreement with an average change between -5 and 5% (‘No change’), agreement on decrease with an average change between -5 and -20% (‘Small decrease’), agreement on decrease with an average change of less than -20% (‘Large decrease’), or disagreement (‘Inconsistent sign’). A consistent result from at least seven of the nine models is deemed necessary for agreement.
