The Competing Effects of Aerial CO2 Fertilization and Drought on Greek Island Fir Tree Growth: What has been the net impact on the growth of the trees? ... and why is the result so important?

Subject Index Summary
Interactive Effects of CO2 and Temperature on Plant Growth (Woody Plants): As the air's CO2 content continues to rise, most trees will likely exhibit increased rates of photosynthesis and biomass production, which can help meet the appetite of earth's expanding human population for wood products. However, certain people claim that CO2-induced global warming will negate the growth-promoting effects of atmospheric CO2 enrichment and actually reduce tree growth. So to determine if this claim has any validity, we here review and summarize the results of several CO2-enrichment studies designed to reveal the net effect of elevated CO2 and air temperature on the growth of trees and other woody plants.
