The Continuing Saga of the Duke Forest FACE Experiment: At the point where the 200-ppm CO2-enrichment of the air in the Duke Forest FACE study had been maintained for a full six years, was there any evidence that the large initial aerial fertilization effect of the extra CO2 had declined with the passage of time?
