Where the article explains it
GCMs, when run with an interactive carbon cycle rather than a prescribed concentration, attempt to simulate and from first-principles biogeochemistry — ocean carbonate chemistry, marine biological production, terrestrial photosynthesis and respiration — so that the partitioning between atmosphere, ocean and land emerges from the model rather than being read off an ice core.
The passage around this formula
The three paths converge on the same physical picture, but for genuinely different reasons: measured composition plus known physics; inferred paleo-composition plus a calibrated proxy relationship; and modeled response, validated against the other two. Treating a modeled sensitivity number as though it had the same evidentiary status as a Mauna Loa flask measurement, or treating an isotope-derived paleotemperature as though it had instrumental-grade resolution, both misdescribe the method. This mass-balance identity — the rate of change of atmospheric carbon equals emissions minus net ocean and land uptake — is the same equation whether it is applied to this decade or to a glacial cycle…
