Actually your statements even have nothing to do with Global warming because you unconsciously assume something and jump too big. But I am glad you mention ice core data. The ice cores from Antarctica reveal that CO2 lags temperature at the end of ice age by 800 years, i.e. temperature change is cause and CO2 change is the consequence during this period. I hope this ice core data revelation can make you re-think your hidden assumption.
BTW, your 2nd statement has been challenged. that is, both natural and anthropogenic emissions have been increasing for over 50 years, not just anthropogenic emissions only.
