Have you ever heard one of these Global Warming nuts explain why we ever had the ice age? I did not think so. I am not sure anyone knows for sure what caused the ice age or why it ended. I know that there must be all kinds of theories out there as too why and I have mine too. That is what this blog is about.
If you know anything about control systems, then you know about "feed backs" or "gains". An example would be when you crest of a hill in your car. As you crest the hill, your car might be going very slow, but as it goes over the crest, it starts to speed up and the farther that it goes down the hill, the steeper the road gets and the faster your car goes. This is a gain or feed back that keep increasing your speed once you go beyond a tipping point. Now back to the ice age.
The concept of green house gases is true. Carbon dioxide is one of those green house gases and most of it is actually dissolved in our sea water. Just like your cold beer, the colder the sea water is, the more carbon dioxide that can be dissolved in it. The fact that the sea water might be getting colder speeds up the rate that the green house gas is taken out of the atmosphere and dissolved in the sea water. The affect is a "gain" or "feed back" that causes the process to go faster and faster until it ends in an ice age. It is just a case of the Earth getting to one of these tipping points where the process will start and then keep going faster and faster. Too many plants taking Carbon Dioxide out of the air could have started the whole thing. Further, the lack of plants could have allowed the volcanoes to build up the Carbon Dioxide again and end the ice age!
The whole process could end with a different tipping point coming along. Most of the Carbon Dioxide comes from volcanoes, not Native Americans building camp fires. With liquid water, it can flow around the Earth equalizing the forces of gravity and rotation of the Earth, but when water builds up in solid ice at the poles, things change. This might be the cause of greater volcanic activity and in the process the Sun's energy could be held close to the Earth by the green house gases. This could start the thaw that we all know happened.
Here is another thing about control systems. Many tend to "ring". It is like a person in a swing. The person goes up in one direction and then back in the other. In this case there is friction that eats up some of the energy of swinging and over time the swing comes to a stop. The fact is that this could take a very long time if the friction was low compared to the amount of kinetic energy in the swing, like a heavy person compared to a young kid. Most systems "ring" and this is what we may have here on Earth.
This is one of my theories and I would be interested in what you think about it.
PS---Think about this. At one time, the Earth was making a lot of coal by plants taking green house gases out of the atmosphere. It must have been a lot,and it could have been the cause of the ice age as explained above. Notice that the Earth is "not" making coal any more. Why do you think that is? Did you hear any global warming nuts explaining why the Earth stopped making coal? Didn't think so!
