Fig. 6 — Time series of (left column) annual O₂ uptake (Gt O₂ year⁻¹) and (right column) monthly O₂ uptake (Mt O₂ day⁻¹) through fossil fuel oxidation as estimated by GCP-GridFED. (Top row) Total global uptake is disaggregated to (other rows) the top 4 emission regions. The plotted uptake uncertainties are based on CO₂ emissions uncertainties of 5% for Annex I nations and global³, and they do not include uncertainties in oxidative ratios.
