I observed, in November 2020, that there is no connection between CO2 emissions and the amount of CO2 in the atmosphere. This suggests that emissions have little or no effect on the concentration of CO2. A recent post at WUWT notes that emissions hit a record high in 2021. What the post doesn’t address is the relationship between emissions and the concentration of CO2 in the atmosphere.
See for yourself. Here’s the WUWT graph of emissions from energy combustion and industrial processes:
Here’s the record of atmospheric CO2:
It’s obvious that CO2 has been rising monotonically, with regular seasonal variations, while emissions have been rising irregularly — even declining and holding steady at times. This relationship (or lack thereof) supports the thesis that the rise in atmospheric CO2 is the result of warming, not its cause.
Dr. Roy Spencer, in a post at his eponymous blog, writes:
[T]he greatest correlations are found with global (or tropical) surface temperature changes and estimated yearly anthropogenic emissions. Curiously, reversing the direction of causation between surface temperature and CO2 (yearly changes in SST [dSST/dt] being caused by increasing CO2) yields a very low correlation.
That is to say, temperature changes seem to drive CO2 levels, not the other way around (which is the conventional view).
Sources for CO2 levels:

Nice to see you back.
