Implications of Our Results  
 The following pages illustrate some of the results to date from the FACE experiment.  The following key points should be noted:
FACE provides a window into the future and allows for experimental testing of CO2/O3 interactions under realistic forest conditions.
Our results suggest that moderate levels of O3 will offset elevated CO2 responses projected for the year 2100.
Our results suggest carbon sequestration under elevated CO2 is being overestimated by modellers who do not consider O3 in areas with periodic episodic O3.
Elevated CO2 delays normal autumn leaf senescence, predisposing some aspen genotypes to winter dieback.
Our preliminary results indicate that aspen and birch insects and diseases may increase under elevated CO2 and O3.

The Northern Forest Ecosystem Experiment (NFEE) is funded by the US Forest Service. The Aspen FACE Experiment is funded principally by the Office of Science (BER), U.S. Department of Energy. Additional support is from the USFS Global Change Program, Michigan Technological University, the Canadian Forest Service and the USFS Northern Research Station.
