This review presents a detailed analysis of the papers published over the past 10 years addressing the response of several physiological parameters to the interaction between salinity and elevated CO2, which are both anticipated to affect more severely future environmental conditions. This review demonstrates that the response to this interaction is species and even cultivar specific and that the predicted higher biomass production at elevated CO2 is not a general trend. Most strategies to cope with salt stress involve active regulation of water potential and stomatal conductance, active regulation of photosynthetic metabolism as a whole, and active regulation of other salt-tolerance mechanisms. However, these salt-tolerance mechanisms are energetically expensive, and even if under elevated CO2 there is generally higher energy supply than under ambient CO2, biomass production will depend on the trade-off between the anabolic (photosynthesis) and catabolic (chloro-, photo-, and basal-respiration) rates, as well as the ability to control the stomatal conductance.
