Residual land carbon sink
IPCC 2001 [19]	-0.3–3.8	incomplete
House et al. [20]	0.3–4.0	1.6–4.8
Additional land carbon uptake due to increased nitrogen deposition (globally)
Townsend et al. [11]	n/a	0.3–1.3
Holland et al. [12]	n/a	1.5–2.0
This study	0.62–2.33	0.75–2.21
Additional land carbon uptake due to increased nitrogen deposition (temperate forests)
Nadelhoffer et al. [10]	n/a	0.25
This study	0.34–1.62	0.4–1.85

Negative values represent atmospheric CO₂ increase (or land sources), positive numbers depict atmospheric CO₂ decrease (land sinks).
