Net land CO2 sink

Atmospheric & Biogeochemical CyclesCarbon Dioxide

This quantity comes from a time series measurement and the most recent value (2018) is reported.


This is equivalent to...

(3.5 ± 0.7) × 1012 kg C / yr

12.8 ± 2.6 Pg CO2 / yr

3.5 ± 0.7 Pg C / yr

HuID: 74574
Relevant Year(s): 2018
Summary: Mass of carbon dioxide (CO2) that is removed from the atmosphere every year by terrestrial plants. The value reported is for 2018, and can be found in Table 6 of Friedlingstein et al (2019). The increase in magnitude of the terrestrial land sink may be due to the effects of fertilization by rising CO2 concentrations and the lengthening of the growing season in northern temperate and boreal areas due to global warming.
Method: The uncertainty value represents one standard deviation. The magnitude of the land sink is estimated from an ensemble of dynamic global vegetation models and constrained with atmospheric inversions.
