A large group of scientists at many different universities have repeatedly confirmed that the CO2 dragon in the sky is a political myth.

H. C. Hottel B. Leckner M. Lapp C. B.Ludwig A. F. Sarofim
and their collaborators on this matter, the combined effect of overlapping
absorption bands causes a reduction on the total absorptivity of a mixture of gases
17 year later, B. Leckner repeated Hottel’s experiment and corrected the graphs plotted by Hottel.
However, the results of Hottel were verified and Leckner found the same extremely insignificant emissivity of the carbon dioxide below 33 °C (306 K)
The results of Hottel and Leckner have been verified by other researchers, like Marshall Lapp, C. B.Ludwig, A. F. Sarofim,who also found the same physical trend of the carbon dioxide.
The general conclusion is that by adding any gas with total emissivity/absorptivity lower than the total emissivity/absorptivity of the main absorb
er/emitter in the mixture of gases makes that the total emissivity/absorptivity
of the mixture of gases decreases.
In consequence, the carbon dioxide and the oxygen at the overlapping absorption spectral bands act as mitigating factors of the warming of
the atmosphere, not as intensifier factors of the total absorptivity /emissivity of the atmosphere
Conclusions
This assessment demonstrates that the effect of an increased warming
caused by an increase of absorptivity of infrared radiation (IR) by
water vapor due to overlapping spectral bands with carbon dioxide does not happen in nature
