It has been postulated that a favorable climatic change occurs worldwide at approximately 900 A.D. At this same time, many cultures expanded and many cultures appeared for the first time, specifically the Initial Middle Missouri Variant in North and South Dakota. In this paper, I will try to demonstrate that a climatic change did occur worldwide, that cultures do respond and change to shifts in climate, and I will try to demonstrate the responses of certain cultures to the 900 A.D. climatic change. Specifically, I will try to show what may have happened to the Initial Middle Missouri culture area during the climatic shift and what may have happened when the beneficial climate started deteriorating.
