Beschreibungen/Notizen

• Global climate and the atmospheric partial pressure of carbon dioxide () are correlated over recent glacial cycles, with lower during ice ages, but the causes of the changes are unknown. The modern Southern Ocean releases deeply sequestered CO sub(2) to the atmosphere. Growing evidence suggests that the Southern Ocean CO sub(2) 'leak' was stemmed during ice ages, increasing ocean CO sub(2) storage. Such a change would also have made the global ocean more alkaline, driving additional ocean CO sub(2) uptake. This explanation for lower ice-age , if correct, has much to teach us about the controls on current ocean processes.
