Short summary

Lysimeter-based manipulative and observational experiments were used to identify responses of water fluxes and aboveground biomass (AGB) to climatic change in permanent grassland. Under energy-limited conditions, elevated temperature actual evapotranspiration (ET_a) increased, while seepage, dew, and AGB decreased. Elevated CO₂ mitigated the effect on ET_a. Under water limitation, elevated temperature resulted in reduced ET_a, and AGB was negatively correlated with an increasing aridity.
