| Zusammenfassung |
| Becker et al. (2013) argue that an afforestation of
0.73 × 109 ha with Jatropha curcas plants would generate an additional terrestrial
carbon sink of 4.3 PgC yr−1, enough to stabilise the atmospheric
mixing ratio of carbon dioxide (CO2) at current levels. However, this is
not consistent with the dynamics of the global carbon cycle. Using a
well-established global carbon cycle model, the effect of adding such a
hypothetical sink leads to a reduction of atmospheric CO2 levels in the
year 2030 by 25 ppm compared to a reference scenario. However, the
stabilisation of the atmospheric CO2 concentration requires a much
larger additional sink or corresponding reduction of anthropogenic emissions. |
