In the absence of human activity, the earth has regularly been going through cycles of heating and cooling.
The heating and cooling cycles are correlated with cycles in solar activity.
CO2 increases follow temperature increases; CO2 decreases follow temperature decreases.
Changes in solar activity drive changes in global warming and cooling; global warming/cooling drives changes in levels of atmospheric CO2.
Changes in atmospheric CO2 are the result, not the cause of, changes in global temperature.
Furthermore: solar-driven changes in global temperature change levels of human activity and population.
Increased human activity has caused an increase in atmospheric CO2.
Therefore, solar-driven changes in global temperature have also been responsible for the changes in the anthropogenic component of atmospheric CO2.
Both the "natural" changes in levels of atmospheric CO2 and anthropogenic changes are effects of a cause that lies entirely outside the realm of human control.
In either case, since the increase in atmospheric CO2 is the result, not the cause, of global warming, trying to decrease the level of the result can do nothing to decrease the degree of the cause. That is, since A causes B and B results in C, fiddling with degrees of C will do nothing to change A and attempting to do so is a waste of time and resources.
Both the “natural” changes in levels of atmospheric CO2 and anthropogenic changes are effects of a cause that lies entirely outside the realm of human control.
Nothing is outside the realm of human control to secular humanists, who have convinced themselves of their own power, in lieu of any “higher” power.
