You can read the individual statements of the science academies. ( https://en.wikipedia.org/wiki/... ) They go much further than simply stating that radiative physics is a real thing. Most state that the IPCC represents the consensus view and that most of the warming over the last 50 years is due to the increase in greenhouse gas concentrations.
Thank you for confirming what I said. The IPCC's Fifth Assessment report is almost verbatim where my assessment of climate models came from. In Chapter 9, Box 9.1 the IPCC report states:
For instance, maintaining the global mean top of the atmosphere (TOA) energy balance in a simulation of pre-industrial climate is essential to prevent
the climate system from drifting to an unrealistic state. The models used in this report almost universally contain adjustments to parameters in their treatment of clouds to fulfil this important constraint of the climate system (Watanabe et al., 2010; Donner et al., 2011; Gent et al., 2011; Golaz et al., 2011; Martin et al., 2011; Hazeleger et al., 2012; Mauritsen et al., 2012; Hourdin et al., 2013).
You'll note that the assessment is backed with a wealth of references to papers confirming that climate models almost universally hand tune clouds to prevent unrealistic energy imbalances. That's not a confidence booster in the predictive power of climate models for telling us what to expect the energy imbalance to do in the future, which is ENTIRELY what the greenhouse effect is.
On of the referenced papers(Golaz et al) goes into more depths of the challenges still presented by this:
We have shown that there is sufficient ambiguity in the CM3 adjustable cloud parameters to construct alternate configurations (CM3w, CM3c) that achieve the desired radiation balance. These configurations exhibit only modest differences in their present-day climatology. Indeed, one would be hard pressed to select the “better” configuration solely based on present-day metrics such as those in Figure2. However, CM3w and CM3c differ significantly in the magnitude of their indirect effects. As a result, their predictions of the 20th century warming are strongly affected (Figures3 and 4).
CM3w predicts the most realistic 20th century warming. However, this is achieved with a small and less desirable threshold radius of 6.0 m for the onset of precipitation. Conversely, CM3c uses a more desirable value of 10.6 m but produces a very unrealistic 20th century temperature evolution.
All of which is to point out that the evidence is climate models still can't simulate the absolutely most fundamental and driving factor of future change, Top Of Atmosphere energy imbalance. But hey, don't let that stop you from lumping climate model results into the global consensus and claiming it as fact. I just ask you be more honest and start calling your belief religious consensus and not scientific.
