Hans-Joachim Weigel, a scientist from the Thuenen Institute, was careful to note that the study shouldn’t be used to undermine attempts to reduce CO2 emissions. Other studies, after all, haven’t linked high CO2 levels with such significant plant growth. Furthermore, within Weigel’s study more didn’t necessarily correlate with better: The increased CO2 levels actually reduced the plant quality. In the future, the researchers are planning to study the effects of rising temperatures on plants, which is a forecasted consequence of increased CO2 emissions. Via PhysOrg
