________________________________________________________________

Over the past 650K years we KNOW that the planet has had at least four similar patterns. These happen every 125K years, with this warming cycle starting about 10,000 years ago and the least warm of the five (four previous and this cycle).

We know that the warming appears to be aligned with planetary movement. When all major planets are on the same side of the sun, we see a far less elliptical orbit of our planet. This coupled with the angle of our planet, in relationship to the sun and the solar activity itself makes determining what is normal for our planet very difficult. We can say though that we should be near the peak of the 125K year cycle in terms of warming.
