Global runoff increases with carbon dioxide (CO2) concentration because of the synergistic effects of physiological responses to CO2 and the responses of vegetation and soil moisture to CO2-induced climate change. These land surface changes are far more important than the direct effects of climate change on global runoff in a CO2-warmed world.

This paper shows that the projected increase in global runoff is mainly caused by vegetation responses to elevated CO2 based on the Budyko framework.

This paper provides a Budyko-based attribution method that can exactly decompose runoff changes into the effects of climate and land surface changes.
