Extended Data Fig. 10: The Random Forest model is extended to predict runoff from snowmelt skillfully.
From: Evidence of human influence on Northern Hemisphere snow loss
R2 (a) and RMSE (b) of Random Forest model predictions of April-July basin-scale runoff from 1981 to 2020. Insets show the distribution of skill across sites, with the red line and value indicating the median. Observed (c) and reconstructed ensemble mean (d) 1981–2020 April-July runoff trends. e, Scatterplot of reconstructed versus observed trends, where each dot represents a basin. Dashed line denotes perfect agreement between reconstructed and observed trends. Spatial correlation is shown in center left. Maps were generated using cartopy v0.18.0. River basin boundaries come from the Global Runoff Data Centre’s Major River Basins of the World database44.
