Let's be specific. Northern hemisphere glaciation. It initiates at a much lower atmospheric CO2 level than the south pole. Don't really know how anyone can argue against this which means they can't argue that CO2 doesn't play a major role in glaciation for the current landmass configuration.Although the exact causes for ice ages, and the glacial cycles within them, have not been proven, they are most likely the result of a complicated dynamic interaction between such things as solar output, distance of the Earth from the sun, position and height of the continents, ocean circulation, and the composition of the atmosphere. So far as I know, we don't know for certain that CO2 is the cause or the effect of ice ages.Who want's them some CO2 now
Yes, it's a combination of things. CO2 is most certainly one of them. Listed as causes or necessary conditions are: polar regions being isolated from warmer marine currents and atmospheric CO2. Trigger events or conditions are orbital cycles and circulation patterns of the ocean. Specifically the gulf stream. Whether is switches off or not.
