........imho the more or less amounts of CO2 in the atmosphere is an effect rather than a cause.

The primary cause is the sun.

actually, less CO2 in the atmosphere resulted in lower green house effect and thus less retained heat and then cooling that allowed massive ice build up

The paper strains and strains to connect current global warming with ancient cooling. for intellectual continuity, the reason for heating and cooling must be the same. The paper proves that reason is atmospheric CO@ levels.

Since there were no men at the time, what caused the cooling and then the following heating?
