[ Your Name ] would like to inform you about this article on Complexity Digest 2001.22 - 05 http://comdig.unam.mx/index.php?id_issue=2001.22#2222 28-May-2001 [ Your Message ] Putting Limits on the Diversity of Life, Science Excerpt: Long-term experiments under realistic conditions are beginning to deliver data on how forests - or at least some forests - will react to increasing levels of CO2 in the atmosphere. The global experiment of increasing atmospheric CO2 concentrations by burning fossil fuels has neither a control nor replicates. So it is difficult to quantify how much faster the world's forests might be growing under high CO2 conditions.
