Can any natural process explain this rate of CO2 increase?

The prior similar question used different data as its basis.
This version of the question is much easier to understand.

  • $\begingroup$ @Michael Walsby: If CO2 from Hawai'ian volcanos was a factor in the Keeling curve, you would see a correlation between volcanic activity and measured CO2, but instead you see a steady increase (with a small but consistent annual variation due to seasonal changes), with no corresponding increase in volcanic activity. $\endgroup$

  • $\begingroup$ @jamesqf They have to skip some readings when the volcano is active. When the volcano is inactive they compare these readings with readings from all over the globe and they are validated. $\endgroup$
