This image needs improvement. I am especially dissatisfied with the glaciation graph labels. "Hot" and "Cold" mean nothing here, and we are given no clear idea of what the graph shows. In fact, it is taken from here: [1] and you will note that it is actually a graph of oxygen-18 flux across that time period, and only has anything to do with glaciation indirectly. You will also note that the graph I link to actually has meaningful numbers on it, to provide a scale metric that does not, in any way, reduce to "Hot" and "Cold". As much as I would like to give the author of this image on WP the benefit of the doubt, it seems apparent to me that s/he has tried to lead people to a particular conclusion in using contextually meaningless terms of temperature, when in fact that is not a temperature graph.

dO18 is highly correlated to temperature (r^2 > 0.7 at Vostok). Dragons flight (talk) 21:05, 4 April 2008 (UTC)[reply]
