My rough interpretation of the data shown in the figures-
1. Daily CO2 conc from the 2nd to the 7th is fairly constant, on the 8th where it hits 400, the data is clearly an an artifact perhaps caused by an instrument malfunction or burp from the volcano. Check your instruments.
2. The long term data is clearly cyclical and the data from 1958 is a short term sample whereas the core data is averaged over hundreds or even thousands of years. You cannot compare the two.
3. The observatory data shows a constant rate of increase over 50 years. Since the amount of CO2 generated over those 50 years has not been increasing dramatically during that time, the rate of increase should be greater now than in the past. It is not.
Correction to my previous post. The 2nd comment should read “HAS been increasing dramatically”.
Apologies
