CO2: Ambient + 200 ppm

Background (scientific objectives)

Increasing atmospheric carbon dioxide (CO2) may lead to global warming and other climate changes. By the processes of photosynthesis and respiration forests exchange CO2 between the atmosphere and the land where it is sequestered as wood and other organic forms and as CO2 in the soil.

Information is needed on these exchange processes in order to predict climate change. Will there be changes in the rate at which trees grow over the next hundred years? Will the storage of carbon in forest trees and soils change? Could changes in forest carbon storage alter global atmospheric CO2 concentrations?

These questions will be answered in the FACTS-I experiment in which the concentration of CO2 is elevated by 50% above the present atmospheric level in three plots in this loblolly pine forest. Three other plots remain at the current atmospheric CO2 level. This experimental design provides a large area in which integrated teams of scientists can describe and quantify processes regulating storage in forests.

The FACTS-I whole-ecosystem manipulation is a flagship experiment of the Terrestrial Carbon Processes (TCP) research program of the US Department of Energy. It is also a core project of the International Geosphere-Biosphere Program (IGBP), and a contribution to the US Global Change Research Program.
