The Ozone depletion was not an result of CO2 and since the mid 80's to late 90's the ozone layer has been recovering to near normal levels

Fact # 2, Humans have been belchin smoke into the atmosphere since the industrail revolution started in the 19th century. While I don't have any pertinent data comparing the belching of humans to the belching of mother earth, I daresay there is a substantial contribution made by humans over time. A steady, over one century long, contribution.

Currently we contribute 3.8 - 5 percent, of that 1/2 is naturally absorb by the environment the balance is released into the atmosphere, the accumulated amount of CO2 over the last 250 yrs is around 160Gtons, most of that prior to the industrial revolution

anyone who would deny that there isn't any human contribution the 'global warming' situation is at best in denial, at worst, a fool.

The human contribution isn't the debate, every living thing, plant & animal and then mother earth is contributing, always have, always will, the debate is the level of contribution being focused towards human ( US in particular )activity purely for political reasons and goals
