Human activities, particularly burning fossil fuel, have increased atmospheric carbon dioxide (CO[sub2]) concentrations. Because CO[sub2] traps heat, continued emissions are expected to change global climate. The extent of this change will depend not only on the rate of emissions, but also on carbon uptake by the oceans and the land. According to some models, land ecosystems can sequester carbon fast enough to help to counteract CO[sub2] emissions. These amounts are equivalent to 22 to 57% of expected anthropogenic CO[sub2] emissions in an intermediate emissions scenario.
