I have said since this whole thing started the following:
Don’t know if global warming is happening or how fast.
Don’t know if it’s good or bad.
Don’t know if we or CO2 are the cause.
Don’t therefore know if we can do anything about it.
Do know every living thing expels or ingests CO2 and without it there would not be life. It is therefore the essence of “sustainability”.
At this time of year as the leaves fall remember every last one was CO2 at one time.

Every leaf on the ground turns back into CO2 as the leaves decompose. Microbes are responsible. Ever notice how light punked firewood is? Same microbes turned it into CO2. The easiest way to figure that out is to weight the leaf litter:
