Terminations.

Abstract

The coincidence between the termination of major glaciations in the Northern and Southern Hemispheres is not easily explained. The association between these events and peaks in Northern Hemisphere seasonality suggests that these rapid warmings are linked to the earth's orbital cycles. The lack of correlation between terminations and the seasonality record for the Southern Hemisphere suggests that the Southern Hemisphere terminations must have been driven by events in the Northern Hemisphere. The global sea level rise, and albedo changes are rejected as the mechanism. Thus, we are left with either large changes in the pattern of deep sea ventilation or CO2 changes in the atmosphere as the agents of interhemispheric transmittal of the climatic message. -from Author
