Ice Ages

These 3 links are about Ice Ages which are primarily a Northern hemisphere event. This is why the warming of the Greenland Sea abyss is included. This is because it is next to the North Atlantic Ridge which becomes the Gakkel Ridge in the Arctic Ocean.
The first link explains that about 800,000 to 1,000,000 years ago a transition happened. Our planet cooled. When this happened Ice Ages went from occurring once every 40,000 years to once every 100,000 years.
If the rising and falling of where the Eurasion and North American tectonic plated meets regulates how for the most part the northern hemisphere is warmed or cooled then a rise in CO2 levels would suggest that the next Ice Age is only somewhere between 10,000 - 20,000 years away. CO2 might only be representative of what our oceans are doing and is not the cause.
Does this matter ? It may not. Since it is a natural geologic cycle once it is accelerated could it be slowed ? Those who live in the Southern hemisphere will not be effected by this.
As for CO2 warming our planet, not supported by accepted global temperature and co2 levels over the last 100 years. The relationship between temperature and co2 levels has only 1 of 3 - 30 year periods that would seem to agree. And that period is also in agreement with the warming of the Greenland Sea.
