Removed "Co2 glacial cycles 800k" Graph
The "Co2 glacial cycles 800k" graph was removed from this article because it uses stratigraphic terminology that is quite antiquated, obsolete, and completely meaningless. This is discussed in the talk section for that figure. Before it can be used, this graph needs to be revised to remove the discredited terminology and have it replaced with the correct terminology.
