Of all of Earth's ecosystems, forests hold the greatest potential for removing CO2 from the atmosphere and sequestering its carbon, even without the boost provided by atmospheric CO2 enrichment. Modeling studies that incorporate the aerial fertilization effect of the ongoing rise in the air's CO2 content show that forests sequester considerably more carbon when growing in a CO2-enriched atmosphere than they do under ambient CO2 conditions.
Even in mature forests that are often assumed to be in a state of equilibrium is this likely to be so; for essentially no forests are in a truly carbon-steady state, as they all leach carbon into the soil profile from whence it eventually makes its way into rivers that flow to the sea, where it is ultimately buried. What is more, research has shown that the buildup of organic carbon in the soils that support the world's forests may go on for millennia.
