a,b, Here, we map changes in year-to-year precipitation variability as CVP (a) and changes in within-year precipitation distribution as the PCI (b) between 1901 and 2014. Plotted values reflect the slope of a linear regression fit to a sliding-window analysis in which values were calculated in sequential 25-year windows for the entire time period. Of the total land area considered pasture in this analysis, 20% did not experience significant changes in CVP (dark grey), 49% experienced significant increases in CVP (warm colours) and 31% experienced significant decreases in CVP (cool colours), P < 0.05. Of the total land area considered pasture in this analysis, 21% did not experience significant changes in PCI, whereas 45% experienced significant increases and 34% experienced significant decreases in PCI over the same time period.
