Abstract

The beginning of the Bølling-Allerød warm period was marked in Greenland ice by an abrupt rise δ[18]O, an abrupt drop in dust rain, and an abrupt increase in atmospheric methane content. The surface waters in the Norwegian Sea underwent a simultaneous abrupt warming. At about this time, a major change in the pattern of global rainfall occured. Lake Victoria was rejuvenated, the Red Sea freshened and Lake Lahontan dessicated. For the AA., the onset of the Bølling-Allerød warm interval appears to have been marked by an abrupt reorganization of the Earth's climate system. Therefore the proposed linkage between the size of African closed basin lakes and insolation cycles must be reexamined
