I don’t think unprecedented rising CO2 level is just a butterfly, and I know this graph isn’t from bad data:
This one covers almost a half-million years of CO2 on Earth (and note that we’re now over 400ppm):
An excerpt from scripps.ucsd.edu
These suggest that the last time atmospheric CO2 was over 400 ppm was at least as far back as the Pliocene, three to five million years ago, before humans roamed the earth and when the climate was considerably warmer than today.
