Please substantiate the claim that the IPCC are wrong in their range of estimates of climate sensitivity. Its a big claim to assert the IPCC are using unsubstantiated denial.
I have not said that the science behind the IPCC estimates for climate sensitivity to CO2 concentration is incorrect, just uncertain given the range of the estimates.
I am not confusing anything - you dont seem to understand what the IPCC are saying and the implications of that uncertainty.
