A possible mechanism of abrupt climatic changes.

Abstract

Many investigations have demonstrated the occurrence of 'abrupt' climatic changes at a time-scale of 100 years during the transitions between glacial and interglacial periods and during interglacials. They are tentatively interpreted as a consequence of prevailing oceanic upwellings (during cold episodes) and downwelling (during warm episodes) and their effects on the air-sea-exchange of CO2 and H2O.-from Author
