I added a graph of Atmospheric CO2 data from ice core samples which closely correspond to global temperature averages.
I tried to sort out the glacial periods and names as best I could, but the older names are known not to represent singular glacial periods, so I tried to represent that on the graph.
I expanded the table to track four sets of names, referenced in the article links. I also corrected the table to match the article dates, but it's still a mess on the older dates.
I welcome anyone else's effort to help clarify this information, even if it is less than well defined. I HOPED the CO2 graph could help shed some light on the glacial periods.

[edit] Asian glaciers?
- The table is great - but it made me think of another question. Why aren't there Asian names? Was there an ice sheet over Siberia too? I've been looking for a map but with no luck. HMAccount 22:27, 25 June 2006 (UTC)

- A good project if you can find more information. Good luck! :) Tom Ruen 21:36, 26 June 2006 (UTC)

- Thanks :) I've had a look on the web, but it is taking too much time. I have found the Siberian ice sheet equivalent of the Riss-Wurm interglacial, the Kazantseva interglacial, and the Wurm equivalent is the Zyryanka glacial period. But there was also the Karginski interglacial and the Sartan glacial period which seem to have been more recently, in the late Wurm, which will throw off your table, so am holding off on adding to it. (reference: [1]) So far come up dry on any earlier glacial periods. Frustrated: I bet it's in any standard Russian geology text :) HMAccount 19:52, 27 June 2006 (UTC)

- Dates are a big issue to connect up since there's different estimates even if you find names. If you feel confident in names and sources for the most recent periods, its seems worth putting up, at least if you include some stub articles in the linked names as well. Of course just including "research notes" here in talk can be helpful if someone else can find more. Tom Ruen 21:03, 27 June 2006 (UTC)
- It is a problem and I notice that some foreign periods are being merged into the the North American system without any discussion or evidence for analogy that I can see. Can anyone link me to policy on this as the scheme is all over the place at the moment? - 217.33.16.99 11:13, 23 February 2007 (UTC)

[edit] The present Pleistocene ice age
The 2nd para refers to "The present Pleistocene ice age". But acc to the Pleistocene article, that era ended 12,000 years ago. If "Pleistocene" is being used in a different sense here, perhaps that should be explained. Nurg 23:18, 3 November 2006 (UTC)
