The passage around this formula

The paleoclimate record measures CatmC_{\text{atm}} at discrete points in time — wherever an ice layer happens to have trapped and preserved bubbles cleanly — rather than continuously, and the temporal resolution degrases with depth as layers compress and diffuse; a single ice sample can represent an averaged interval of years to centuries depending on accumulation rate and depth, a resolution loss with no instrumental equivalent. It cannot measure E(t) or the ocean and land flux terms directly at all; those are inferred from the shape of the concentration curve itself combined with independent proxies for ocean circulation and terrestrial productivity, compounding uncertainty rather than…
