doesn't give a specific figure, but does give a graph - Figure 3 - of
the measured CO2 forcing rising with CO2 concentration, showing it to
have reached 1.7 Watts per square metre. The introduction at the top
of the web-page makes it clear that the uncertainty on this figure is
around 10%, which matches the Colorado numbers.
Your claim was
"The AGW contribution alleged from CO2 is, well, not even clear. A
range of estimates from ~0.25 to
1 W/m^2 out of roughly 300W/m^2 has been offered."
You can't substantiate this claim, or tell us where you got it, and in
fact it seems to be flat out wrong.
Do tell us again how much you know about climate modelling, and about
the excellent advice you can get from someone directly involved in the
subject - we need a good laugh.

The NOAAA web-site, which you snippedgives a figure of 1.66 W/m˛, with a range between 1.49 and 1.83 W/m˛.
