If the IPCC didn't allow dissenting opinions why do they rate their conclusions on Confidence and Likelihood. Without dissent, they'd all be certainties.Only 1/4 to 1/3 of the associated warming in the IPCC models is attributed to CO2. The other 2/3 to 3/4 are from feedbacks (water vapor, cloud formation and precipitation) that they pile on which are highly controversial. You probably don't know this because the IPCC doesn't allow dissenting opinions in their reports.
The fact that you don't know this and have such strong opinions is astonishing.
From Pg 38 of the AR6 Technical Summary
1) Confidence1 is a qualitative measure of the validity of a finding,
based on the type, amount, quality and consistency of evidence
(e.g., data, mechanistic understanding, theory, models, expert
judgment) and the degree of agreement.
2) Likelihood2 provides a quantified measure of confidence in
a finding expressed probabilistically (e.g., based on statistical
analysis of observations or model results, or both, and expert
judgement by the author team or from a formal quantitative
survey of expert views, or both).
Where there is sufficient scientific confidence, findings can also be
formulated as statements of fact without uncertainty qualifiers.
Throughout IPCC reports, the calibrated language is clearly identified
by being typeset in italics.
