Projected CO2 Concentration
qProjecting the future CO2 concentration is more difficult than projecting the emission levels.
qThe future
concentration of CO2 in the
atmosphere also depends on how the
climate system redistribute the excessive
CO2 among its carbon reservoirs
(such as ocean and biosphere).
qCO2 level in the atmosphere peaks centuries after CO2 emission reaches its peak.
qThis is
related to the fact that it take time for
ocean to remove the excessive
CO2 from the atmosphere.
