Effects of ozone on vegetation are modified by nitrogen and factors of climate change

Tropospheric ozone has been identified as the most damaging air pollutant to vegetation. •The impacts of ozone in a future nitrogen polluted and changing climate depend on the ozone sensitivity of plant species and the respective concentration and intensity by which the climate change factors interact with ozone. •While both elevated CO2 and nitrogen input offered some protection from ozone damage, drought stress can exacerbate the negative effects of ozone.
