With Ice Ages, we find a similar pattern of cyclical pattern formations as we do in markets. About 2.6 million years ago, that is when the Earth entered the Pleistocene period. This was marked by an interesting cyclical pattern whereby there were these deep ice ages that came at regular 43,000-year intervals. Then about 1 million years ago, the Earth entered what is known as the Mid-Pleistocene transition period. It was here where these ice age cycles suddenly expanded from 43,000-year intervals to nearly 100,000-year cycles. The last one was about 11,000 years ago. This is not referring to the Mini-Ice Age of the 1600s.
