Short summary

The amount of fossil-fuel-derived carbon dioxide that was taken up by land biosphere and ocean was evaluated from atmospheric carbon dioxide and oxygen observations in the western Pacific over a 15-year period. The results showed that about 30 % and 17 % of the fossil-fuel-derived carbon dioxide emitted during a 17-year period (2000–2016) was taken up by the ocean and land sinks, respectively. Long-term trends of land and ocean sinks for the decadal period were also evaluated.
