I was looking for the answer to this question but could not find it.
I know about the Milankovitch Cycles and how the cooling temperatures led the CO2 decline by having the cooler oceans absorb more CO2 after the climate had ALREADY cooled (as one example). However, was there enough CO2 being locked up in the growing ice sheets to draw down global levels to push the cooling even further? Just the increased albedo of the ice compared to land or sea water was part of the positive feedback.
Also, that may help push the thaw faster as CO2 would be released during the deglaciation. So, maybe a practical question is whether there is currently a lot of CO2 in the Greenland and Antarctic ice sheets waiting to be released. But let me aside here and say that with our fixed infrastructure ports and shore cities we will be screwed independent of this wrinkle.
Again, I am just asking about the raw numbers of how much CO2 was likely to be in glaciers compared to the global budget.
