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...

Excited to share our new paper "When and where soil dryness matters to ecosystem photosynthesis" www.nature.com/articles/s41..., which resolves a long-standing debate as to whether soil moisture or atmospheric dryness dominates water stress response.
When and where soil dryness matters to ecosystem photosynthesis - Nature Plants
Using a causality-guided explainable AI framework, Liu et al. show soil moisture dominates vapour pressure deficit in shaping global photosynthesis during water-limited conditions.

It is terrible that we will not actively mitigate in the US and will strongly affect our future. However the term adaptation cannot be considered a soothing term. We need both to adapt and mitigate given the long time scales in the system and time to reach net zero.
