Oh, by the way, the temperature "record" of that very first graph was hand-drawn and not meant to be a quantitative representation of the geologic temperature record. It's old and meant to be an indication of "hot" and "cold" periods. Hence the unchanging flat-lines for millions of years.

Here is a graph based on data, and even the data today is sparse so this one isn't even all that accurate.
