Reproductive Responses of Paper Birch Trees to Elevated CO2 and O3 Concentrations

CO2 Science

In the one-sentence capsule summary of their work, the six researchers write that "in this study, we found that elevated CO2 enhances and elevated O3 decreases birch reproduction and early seedling growth," while in the concluding sentence of their abstract, they write that "the evidence from this study indicates that elevated CO2 may have a largely positive impact on forest tree reproduction and regeneration while elevated O3 will likely have a negative impact." Yet radical environmentalists and climate alarmists continue to brand CO2 a harmful air pollutant, with many governmental agencies the world over actually buying into this gross misrepresentation of reality.
