Are there links between carbon dioxide and temperature in the ice age

The science on the Ice Ages is still uncertain. It is clear that they were triggered by some other cause, very likely the Milankovitch cycles, and that carbon dioxide levels only rose gradually over a period of almost a thousand years after the start of the Ice Age periods.

Milankovich cycles can cause a very small reduction in average global temperatures over a period of centuries, but are considered too weak to be the only explanation of the ice ages. Scientists say that as the earth cooled slightly, as a result of a change in the Milankovich cycle, the level of atmospheric water vapour fell, resulting in a gradual further fall in temperatures. Eventually, carbon dioxide concentrations began to fall in tandem with falling water vapour levels and reinforced the global cooling, until an ice age was underway.A:
Absolutely there is a connection. Every start to temperature drop has been during times of high CO2 levels. Every warming period has started during times of known low CO2 periods. We know this to be the case through glacial and holocene data. We have also determined why this occurs. Most of the atmosphere’s CO2 is absorbed by open waters. In particular, the open waters of the Northern Ocean. When temperature warm, water is unable to absorb CO2 as quickly as it does when it is cooler. This is why, in all of the earth’s history, we have never seen stable CO2 levels. They will always follow the temperature by 10 to 800 years. The Milankovich theory explains the great temperature swings of the past 4 ice ages. These temperature swings have always caused changes far in excess of any other driving force, The current warming trend, which started 10,200 years ago started through this cycle.
