Duke University began exposing North Carolina forest plots to elevated CO2; after 10 years, loblolly pines produced about 20% more biomass

The long-running Free-Air Carbon Enrichment (FACE) experiment exposed forest plots to elevated carbon levels under open-air conditions instead of enclosing the trees in chambers. By 2007, researchers reported that after a study of over 10 years, the treated, loblolly-pine-dominated plots had produced around 20% more biomass on average than matched plots receiving ambient carbon dioxide levels.
