LOL Never saw that before. Very good. Keep posting. There are always new people viewing FR pages and there are old FR posters and lurkers who haven't seen everything. I'm one, I have seen charts like those but not those specifically and they are particularly clear.
I probably should add that those charts are from the Wikipedia article on “Ice Ages”, which is really quite interesting, even if one finds fault in parts of it. The basic data, including the height of the last interglacial, is telling. The relative flatness of the present interglacial is also intriguing. But, how long can it last? The record is not encouraging.
