Abstract

A stomatal frequency record based on buried Tsuga heterophylla needles reveals significant centennial-scale atmospheric CO (sub 2) fluctuations during the last millennium. The record includes four CO (sub 2) minima of 260-275 ppmv (ca. A.D. 860 and A.D. 1150, and less prominently, ca. A.D. 1600 and 1800). Alternating CO (sub 2) maxima of 300-320 ppmv are present at A.D. 1000, A.D. 1300, and ca. A.D. 1700. These CO (sub 2) fluctuations parallel global terrestrial air temperature changes, as well as oceanic surface temperature fluctuations in the North Atlantic. The results obtained in this study corroborate the notion of a continuous coupling of the preindustrial atmospheric CO (sub 2) regime and climate.
