Multiple carbon cycle mechanisms associated with the glaciation of Marine Isotope Stage 4

Multiple carbon cycle mechanisms associated with the glaciation of Marine Isotope Stage 4

Summary for general audience: We used carbon stable isotope data from an Antarctic ice core to evaluate which mechanisms caused changes in atmospheric carbon dioxide 74-59 thousand years ago, including a ~40 ppm decrease at the beginning of the last ice age.
