The Human Impacts Database

A collection of useful numbers for quantifying the impacts of the human presence on Earth.

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


Value:		(1.28 ± 0.26) × 10¹³ kg CO₂ / yr see this value in other units 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.
