Interested in how plant intrinsic water-use efficiency (iWUE) responds to rising CO2? Our new paper shows that CO2-enhanced iWUE is mainly driven by reduced canopy conductance, while stimulation of ecosystem photosynthesis is less detectable given current data length. www.nature.com/articles/s41...
