Why this formula appears here
The instrumental record measures essentially continuously and directly, at sub-part-per-million precision, at Mauna Loa and a global network of comparable stations, and can resolve seasonal cycles as well as the long-term trend [ 1 ] . E(t) , anthropogenic emissions, is compiled from energy and land-use statistics rather than measured atmospherically at all — a different evidentiary category again, closer to an audited inventory than a physical observation.
