Atmospheric CO2 follows ocean temperatures, not man’s combustion.

Man’s rate of CO2 creation is increasing, yet the rate of change in atmospheric CO2 is highly variable.
The rate of change in atmospheric CO2 is highly correlated with atmospheric temperatures, which are highly correlated with ocean temperatures and cycles.
Man’s production of CO2 can not explain the large variation is either the atmospheric CO2 or atmospheric CO2. Ocean temperatures can explain both.
There is no mechanism by which CO2 would allow global temperatures to cool, CO2 only increases, and it only absorbs more and more energy. CO2 can’t explain the large rapid coolings which frequently occur.
