File talk:Atmospheric CO2 with glaciers cycles.gif

This looks like original work to me. The author took data from different sources and combined them for this graph to provide more information than the sources. This is synthesis, and is unverified. I suggest a verified source for a similar chart if one is available. If no such verified chart is available, then this confirms this chart as original work, and has no place in Wikipedia, particularly when the credentials of the author are unknown.

 * The only synthesis is labeling geologically named ice ages with CO2 graphs from Antactica ice cores. I'm very happy if anyone can replace this with a better graph. I don't believe Wikipedia has requirements that every graph presented here must be a duplicate of a singular graph elsewhere. Tom Ruen (talk) 14:20, 24 September 2008 (UTC)
