    Yes.  According to a recent study by the University of Wisconson, aspen trees are now growing about 53% faster than they were 50 years ago.  The scientists believe the effect is due to the increasing levels of CO2 in the atmosphere.  They also speculate that the rate of tree growth will continue to increase as CO2 levels rise over the next few decades.
