Extended Data Fig. 1: Precipitation partitioning in the present and future.
From: Mid-latitude freshwater availability reduced by projected vegetation responses to climate change
a., WY partitioning [mm/yr] of precipitation (P) among the canopy (C/P, green), runoff (Q/P, blue), and soil + storage (S/P, red), shown as fluxes in the current climate. All else equal, high [CO2] and warming-induced VPD could close stomata, decreasing transpiration and increasing soil water and runoff, as in b. Soil water and runoff could alternatively decrease as longer and warmer growing seasons and CO2 fertilization increase ecosystem water demands, leading to reductions in soil water and runoff, as in c.
