So what I would like to know in that case is how it is losing/regulating its heat? could it be possible that the IR wavelength changes that much that it ia not absorbed by the CO2 anymore?
Or has the assumed fact drifted away from realtity?
I'm not looking for any other information other than whats happening on Venus, as I do understand that this is a hotly contested issue at the moment,

I can find plenty of references to how it got like we see it today (runaway greenhouse effect). Most say that it has now stabalised but do not go on to say how.
I saw a figure of 65% of sunlight is reflect away so no doubt that is one factor.
I did find
this which discusses it. Not a light read and I have not read it fully. It would appear that your very good question is still open for study and debate.
