I am guessing you did not read these!
The Fourth National Climate Assessment is a joke, in that they use RCP8.5 as an upper limit, RCP 8.5 is not possible.
The PNAS paper is a what if paper starting with the assumption that CO2 sensitivity is already proven,
ACP is a model (says it right in the title) "a multi-model analysis"
ACP - Potential climate forcing of land use and land cover change
This one is interesting but attributes 40% of the observed forcing to changes in land use.
IPCC AR5 does not actually validate the predicted effects of added CO2, if you think it does you need to cite the paragraph.
This paper,
https://agupubs.onlinelibrary.wiley.com/doi/abs/10.1029/JC084iC08p04949
can be invalidated by the data alone,
The statement
Is almost the complete opposite from the observations.
What you have here is your failure to understand that no one has actually validated that CO2 preforms as advertised.
The simple fact that the forcing imbalance estimate has been steadily declining for almost 20 years, and the observed data shows it is
lower than current estimates.
