. Serving source water for the Yellow, Yangtze and Lancang-Mekongrivers, the Sanjiangyuan region affects 700 million people over itsdownstream areas. Recent research suggests that the Sanjiangyuan region willbecome wetter in a warming future, but future changes of streamflow extremesremain unclear due to the complex hydrological processes over high-landareas and limited knowledge of the influences of land cover change andCO 2 physiological forcing. Based on high-resolution land surfacemodeling during 1979–2100 driven by the climate andecological projections from 11 newly released Coupled Model IntercomparisonProject Phase 6 (CMIP6) climate models, we show that different acceleratingrates of precipitation and evapotranspiration at 1.5  ∘ C globalwarming level induce 55 % more dry extremes over Yellow River and 138 %more wet extremes over Yangtze River headwaters compared with the referenceperiod (1985–2014). An additional 0.5  ∘ C warmingleads to a further nonlinear and more significant increase for both dryextremes over Yellow River (22 %) and wet extremes over Yangtze River(64 %). The combined role of CO 2 physiological forcing and vegetationgreening, which used to be neglected in hydrological projections, is foundto alleviate dry extremes at 1.5 and 2.0  ∘ C warming levels but tointensify dry extremes at 3.0  ∘ C warming level. Moreover,vegetation greening contributes half of the differences between 1.5 and3.0  ∘ C warming levels. This study emphasizes the importance ofecological processes in determining future changes in streamflow extremesand suggests a “dry gets drier, wet gets wetter” condition over thewarming headwaters.

Accelerated hydrological cycle over the Sanjiangyuan region induces more streamflow extremes at different global warming levels
