The convolution integral form of a carbon cycle model is transformed to a simple first‐order differential equation. This allows one to derive an extremely efficient numerical algorithm for the carbon cycle model. The algorithm can be easily inverted to obtain a practical and efficient inverse carbon cycle model. The model is described and an example is given showing how modelled land‐use‐change emissions over 1765–1990 vary with assumptions made regarding the efficiency of oceanic CO 2 uptake.
