Sure, we release a lot of CO2 in the air, but it's insignificant as a greenhouse gas. Water vapor may not be as good a greenhouse gas as CO2 molecule for molecule, but it accounts for more of a percentage in our atmosphere percentage wise. Methane is a much smaller percentage wise, but is a far more potent greenhouse gas. IPCC's report pretty much ignored the fact that water vapor is also a greenhouse gas. It assinged all the heating to CO2.

Can you provide any evidence, such as a scientific paper or scientist or just a wiki page that CO2 is insignificant as a green house gas?
I am all too aware that methane has a much worse effect on the atmpsphere. And GW is seen in terms of that 'Human actions are changing the chemical composition quantities of the atmosphere', then water vapour (as I already recognized as a green house gas/component in a quote) remains constant and at natural levels because we do not ADD or release water vapour but we release tonns of carbon which does alter the quantities thus temperature. You must distinguish between organic green house chemicals which result in creating life through making the atmosphere oxic and a specific temporature and polutant green house gases which are the same chemicals but released by humans therefore altering the chemical composition of the at....ere.
If you believe CO2 is insignificant because of it being a tiny percentage of the overall atmospheric make up, then you must also believe Ozone is irrelevant because its even less than carbon but it just protects the earth from UV rays and also can be affected by human alteration of chemical substances through introducing CFC's. But then again the earth is alot flat isn't it.
If you refer to one of my posts above the actual quantity of carbon in the at...ere is naturally small but that does not mean its insignificant, the fact of the matter is if you introduce more of any subtance into the atmo...ere then you alter the chemical composition affecting oxic and temperature. Refer to the evolution of the atmosphere over billions of years and what the climate was like on the ground at the time
