Just Modulatin'

When I threw together the deviation from mean of the Mauna Loa above I used the full average monthly variation which includes the rising trend in CO2 concentration. Nothing good or bad about that, just should be noted. Also the right Y-axis is for the deviation from mean.
This is the deviation from mean using the full Mauna Loa record with the trend in CO2 removed. This is just the monthly change as provide by the NOAA minus the average monthly change. This is on the same Y-axis to show the magnitude of the deviation. Comparing the two may be useful to see what impact the increase in CO2 concentration has on some of the variability in climate.
Just in case you were wondering, here is the average Mauna Loa change with the tropical ocean and northern extent land for comparison. Note that the temperature scale is on the left and the CO2 scale on the right.
