The observation that CO2 is a ghg (greenhouse gas) is a shallow penetration of the science and…

Yeah, because climate researchers aren’t actually calculating climate forcing impacts with detailed models (e.g. Shindell et al., Science, Oct 2009) , just looking at radiative heat transfer properties and making broad conjecture. Yup, you sure nailed them (/sarcasm). Your gross oversimplification of how CO2 impacts are evaluated is misleading to other readers and disappointing.
