Modeling the Potential Sensitivity of Slash Pine Stem Growth to Increasing Temperature and Carbon Dioxide
There is a widely recognized possibility that the earth’s climate may change at an unprecedented rate during the next century. General circulation models (GCMs) of the atmosphere predict that the global annual average temperature will increase 2 to 5 °C in response to increased levels of greenhouse gases. This is the equivalent to a doubling of atmospheric carbon dioxide (CO2) concentrations from preindustrial levels (Schneider et al., 1991). Although there are many uncertainties concerning the magnitude and pattern of regional climate changes (Dickinson, 1989), the time-scale of forestry management requires serious consideration of possible future effects now.
