| Zusammenfassung |
| The estimated global CO2 emission rates and the measured atmospheric
CO2 concentrations show that only a certain share of the emitted
CO2 accumulates in the atmosphere. For given atmospheric emissions of
CO2, the effective lifetime determines its accumulation in the
atmosphere and, consequently, its impact on the future global
warming. We found that on average the inferred effective lifetime
of CO2 decreases as its atmospheric concentration increases, reducing
the rate of its accumulation in the atmosphere. We derived a power function
that fits the varying lifetimes. Based on this fitting function, we
calculated the increase of CO2 for different scenarios of future global
emission rates. |
