Abstract

Globally, surface-level concentrations of both CO₂ and ozone (O₃) are increasing annually. Because many studies have shown beneficial effects of increasing CO₂, predictions have been made that elevated levels of CO₂ would compensate for growth decreases caused by O₃. For the past two years, we have been examining the interaction of O₃ and CO₂ on trembling aspen (Populus tremuloides) and eastern white pine (Pinus strobus) in open-top chamber studies involving both plants in pots and plants growing in the ground.
