Extended Data Fig. 5: Statistically significant increases and decreases in dry and wet local deviation frequency.

From: Notable shifts beyond pre-industrial streamflow and soil moisture conditions transgress the planetary boundary for freshwater change

Extended Data Fig. 5

Panels show increases and decreases in dry and wet local deviation frequency for streamflow (a) and soil moisture (b). Changes in the frequency of local deviations are computed by comparing the ensemble median frequency of local deviations during 1976–2005 against 1691–1860, and significance of change is tested at a 95% confidence level (P = 0.05) with R package stats function prop.test96 (one-sided test). The changes are classified according to the direction of change (decreasing or increasing frequency of deviations) but with no regards to magnitude. Percentage shares of ice-free land area covered by each class are represented in the bivariate legend.
