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…
