Climate change increases the risk of ozone damage to plants.

Risk of ozone damage greatest in central Europe
"The results show that the risk of ozone damage to plants is greatest in central Europe where ozone concentrations are high and climatic conditions promote uptake of ozone through the stomata. Weather and climate affect both the concentration of ground-level ozone in the ambient air and to what degree the stomata are open."
However, the risk of ozone damage is also affected by the carbon dioxide concentration in the air. Research indicates that the plants' stomata are less open when the concentration of carbon dioxide increases.
"The models show that higher carbon dioxide concentrations in the air could mean that the risk of ozone damage to crops and deciduous trees will not increase," says Klingberg.
"But the magnitude of this effect is uncertain, especially for trees. If the effect of carbon dioxide on the stomata will turn out to be small, future climate change has the potential to significantly increase the risk of ozone damage to vegetation in northern and central Europe."
