I am going to guess that you extrapolated "millions of years" from the data set that went back 50 years in their data?
I didn't see any information in the link that showed ppm levels of co2 from millions of years ago.

Could you imagine the wars and destruction if people started fighting for small food reserves and heating fuel?
I have yet to see anyone link the ppm to a specific average temperature increase or decrease. Doing some simple math should be able to tell us just exactly how much warmer the planet will be if all the coal, oil, and gas is depleted.
