Fig. 1: Global 30-year mean river discharge, corrected using mean observations.

a, Corrected global river discharge estimates. Black arrows point to locations that result in negative river discharges, which are indicative of the human footprint on the water cycle. b, The difference between corrected and uncorrected estimates. Green areas indicate positive differences and, therefore, locations where the corrected simulations resulted in greater discharge estimates than uncorrected. Brown areas indicate negative differences and, therefore, locations where the corrected simulations resulted in smaller discharge estimates than uncorrected. Crosshairs in Antarctica indicate no data. Maps created in QGIS, using graticules from Natural Earth.
