Milankovic Cycles and Climate
I got the data to plot the Milankovic cycles for the spread sheet in a post at Watts Up With That, "Onset of the Next Glaciation". and the Sea Surface Temperature data form the NOAA paleo website.
Comparing to the Antarctic data provide by Wikipedia, the period between those two events somewhat compares to the ice cores. The range of temperature change in the ice cores though is 5 times or more the change in the SST data. CO2 outgassing would be dependent on the average ocean temperature near the Antarctic.
Since the sample ages are inconsistent between data sets, it may take me a while to do a proper analysis, but then that is not my yob mans. I am sure some grad student somewhere would love to take this ball and run with it. If they figure out the fine details of the Milankovic versus CO2 theories, they may get a decent grade.
