Abstract

A simple impulse-decay model driven by the history of atmospheric dust loading from Greenland can match the history of glacial-interglacial changes in atmospheric carbon dioxide concentration rather accurately, if model parameters are tuned within physically possible ranges; forcing with the Greenland temperature record produces a similarly good match. Calculations using southern forcing do not match as accurately. These results leave open the possibility of northern control of glacial-interglacial carbon dioxide changes.
