Summary

| Description |
English: "[…] for fossil CO2 emissions (EFOS, including a small sink from cement carbonation; grey) and emissions from land-use change (ELUC; brown), as well as their partitioning among the atmosphere (GATM; cyan), ocean (SOCEAN; blue), and land (SLAND; green). Panel (a) shows annual estimates of each flux (in Gt C yr−1) and panel (b) the cumulative flux (the sum of all prior annual fluxes, in Gt C) since the year 1850. The partitioning is based on nearly independent estimates from observations (for GATM) and from process model ensembles constrained by data (for SOCEAN and SLAND) and does not exactly add up to the sum of the emissions, resulting in a budget imbalance (BIM) which is represented by the difference between the bottom red line (mirroring total emissions) and the sum of carbon fluxes in the ocean, land, and atmosphere reservoirs. All data are in gigatonnes of carbon per year (Gt C yr−1) (a) and gigatonnes of carbon (Gt C) (b). The EFOS estimate is based on a mosaic of different data sets, and has an uncertainty of ±5 % (±1σ). The ELUC estimate is from three bookkeeping models (Table 4) with an uncertainty of ±0.7 Gt C yr−1. The GATM estimates prior to 1959 are from Joos and Spahni (2008) with uncertainties equivalent to about ±0.1–0.15 Gt C yr−1 and from Lan et al. (2023) since 1959 with uncertainties of about ±0.07 Gt C yr−1 during 1959–1979 and ±0.02 Gt C yr−1 since 1980. The SOCEAN estimate is the average from Khatiwala et al. (2013) and DeVries (2014) with an uncertainty of about ±30 % prior to 1959 and the average of an ensemble of models and an ensemble of fCO2 products (Table 4) with uncertainties of about ±0.4 Gt C yr−1 since 1959. The SLAND estimate is the average of an ensemble of models (Table 4) with uncertainties of about ±1 Gt C yr−1. See the text for more details of each component and its uncertainties."
