Abrupt change in atmospheric CO₂ during the last ice age

Creator:

Ahn, Jinho, Brook, Edward J., Schmittner, Andreas, and Kreutz, Karl

Abstract:

During the last glacial period atmospheric carbon dioxide and temperature in Antarctica varied in a similar fashion on millennial time scales, but previous work indicates that these changes were gradual. In a detailed analysis of one event we now find that approximately half of the CO₂ increase that occurred during...

Southern Ocean control of glacial AMOC stability and Dansgaard-Oeschger interstadial duration

Creator:

Buizert, Christo and Schmittner, Andreas

Abstract:

Glacial periods exhibit abrupt Dansgaard-Oeschger (DO) climatic oscillations that are thought to be linked to instabilities in the Atlantic meridional overturning circulation (AMOC). Great uncertainty remains regarding the dynamics of the DO cycle, as well as controls on the timing and duration of individual events. Using ice core data we...
