Loblolly pines may reproduce earlier--and more abundantly--in a future environment pumped up with carbon dioxide, according to a new study reported on page 95. The conclusions are among several now beginning to emerge from an ambitious, decade-long project that aims to predict the effects of high COlevels on both the trees and the ecosystem as a whole. Already, the project has confirmed one key result of earlier small-scale experiments: that high COlevels can spur faster photosynthesis and growth.
