Plant response to elevated CO2

A study that simulated the effects of elevated atmospheric carbon dioxide on plants revealed that water savings from tighter regulation of leaf pores and changes in leaf canopy density drove on average 28% of ecosystem productivity response to elevated carbon dioxide concentration and more than 50% of ecosystem productivity response in dry sites with C4 grasses, indicating that carbon dioxide fertilization effects are likely largest in water-stressed regions. - Read at PNAS.org
