The heating or cooling of Earth’s surface and oceans can cause changes in the natural sources and sinks of these gases, and thus change greenhouse gas concentrations in the atmosphere
When CO2 rises or lowers, it affects the oceans. More water goes in from melting, more water is held in the atsmosphere because it is warmer, and more heat is held in because of the excess water vapor.

CO2 levels varied in tandem with the glacial cycles
Glacial melting changes along with any change is temperature (melting and freezing)
