Just a few pedantic clarifications of how I read Read-Only:
One of my biggest concerns with manmade climate change, is the way this particular area of science silences the opposition, more like mafia style politics than science. If you look at physics theories, for the essence of matter and energy, there are several theories allowed side-by-side. The consensus may prefer the standard or quantum model, but there is no political effort to silence those who accept string or loop theories. Why the difference? Normally science is open minded and not this way or the highway. I was wondering if anyone knows why this area is so different?
There are NOT "several theories allowed."
Specifically, a scientific theory is the current state-of-the-art most parsimonious, most precise description of all behavior in a problem domain. Things that are not as precise as current theories are not viable hypotheses. Things that were former most precise descriptions of behavior are out-of-date scientific theories. Things that are as precise as modern theories but are not the most parsimonious or that have not yet been proven to be less precise than the state-of-the-art are hypotheses -- you know, "informed guesses."
So for a given problem domain, there can be at most one theory because that's what the word best means. We see the state-of-the-art change as later hypotheses may have wider domains than the current state-of-the-art.
Example domain: Neutrino propagation physics: Quantum field theory in a background of curved space-time
Example domain: Particle physics, excluding neutrino propagation or Terrestrial physics where self-gravitation is neglected: The standard model circa 1970 in a background of curved space-time.
Example domain: Terrestrial physics where self-gravitation and bulk electromagnetic effects are the only effect studied or the celestial dynamics of astronomical bodies: General Relativity with Maxwellian electromagnetism.
Currently there are no examples of self-gravitation of fundamental particles being studied, no bulk effects of weak- or strong-force interactions, and no examples of particles deflecting astronomical bodies, so these problem domains remain experimentally distinct; each with just one best-of-class theory for each.
That's the sort of talk one only gets from deniers.
Deniers
and those with so little expertise in the ways of science as to confuse accepted theories, still-viable hypotheses and non-viable hypothesis.
The reason is quite simple - the standard models MATCH the data available. Case closed.
And they are parsimonious. Just as Newton refused to speculated on why gravity acted as it does, so good science worked with questions of observable behavior, not unobservable mechanisms that purport to explain the whys of that behavior.
Now on to the meat of responding to wellwisher's post:
I think you have this wrong.
Is your opinion based on facts and rational argument? Is it based on relevant expertise? Why should your opinion matter to anyone but you?
All those theories are acceptable in physics and all physicist are allowed to study and move back and forth.
Not “
all”. Just the ones that correspond with reality. And those hypotheses that correspond closely to reality closely correspond to each other. That's why for most human-scale mechanical engineering jobs, pure Newtonian mechanics in a constant acceleration field is sufficient.
In the exact same way, future theories are constrained by a need to closely correspond to the current state-of-art predictions.
However, all are complicated and each would take years to master so people tend to pick one.
To date, no one has mastered string theory or loop gravity to the point where the theories have precise answers to all the questions routinely answered by current state-of-art physical theories. Thus these are not scientific theories in the sense of being empirically verified by experiment -- they are merely hypothesis that a lot of effort has gone into to hopefully demonstrate or refute their viability.
It is not one or the other, or we will boycott you.
There may come a day when these one or more of these hypotheses will be proven incompatible with reality and thus preventing further publishing of papers predicated on the concept that they are viable hypotheses of out reality. That's not censorship of fairly held opinion, but a raising of the level of discussion above that of uneducated bloviation.
One may say the standard model is the consensus, but the others are free to be explored, without name calling and buzz words to force conformity.
One is welcome to explore the physical predictions of any assumptions, but one is not free to say those assumptions describe reality if they do not. You have assumed conformity is the result of censorship of viable ideas when using the filter of reality is a sufficient hypothesis.
One might also notice no political divide, just science, since all these theories conform to the principles of the scientific method. Why is climate theory so intolerant of any other POV even it it conforms to the scientific method?
You have not given evidence that any hypothesis in opposition to the vast majority of papers that find support for anthropogenic global warming are the best hypotheses that explain all the data in the relevant problem domain. Thus you have not demonstrated that other ideas are scientific theories. Thus you answer your own question and expose it false premise.

Loop quantum gravity is string theory’s biggest competitor. It gets less press than string theory, in part because it has a fundamentally more limited goal: a quantum theory of gravity. Loop quantum gravity performs this feat by trying to quantize space itself — in other words, treat space like it comes in small chunks.
In contrast, string theory starts with methods of particle physics and frequently hopes to not only provide a method of creating a quantum theory of gravity, but also explain all of particle physics, unifying gravity with the other forces at the same time. Oh, and it predicts extra dimensions, which is very cool!

In contrast, a brief visit to Wikipedia explains one of the major reasons that Loop Quantum Gravity is not yet proven to be a viable competitor with general relavity: The correspondence principle again.

The Standard Model falls short of being a
complete theory of fundamental interactions because it makes certain simplifying
assumptions. It does not incorporate the full theory of
gravitation[2] as described by general relativity, or predict the accelerating expansion of the universe (as possibly described by
dark energy). The theory does not contain any viable
dark matter particle that possesses all of the required properties deduced from observational
cosmology. It also does not correctly account for
neutrino oscillations (and their non-zero masses). Although the Standard Model is believed to be theoretically self-consistent[3] and has demonstrated huge and continued successes in providing experimental predictions, it does leave some
phenomena unexplained.

Landau pole), but the predictions extracted from the Standard Model by current methods are all self-consistent. For a further discussion see e.g. Chapter 25 of R. Mann (2010). An Introduction to Particle Physics and the Standard Model. CRC Press. ISBN

One may notice how objective to itself the standard model is and who does not sales pitch, we know all for popular appeal. Why is this done in physics and not in climate science?
Because climate science already has models that cover the question of the causes of global warming, and anthropogenic causes dominate natural ones
and remaining uncertainties. Also, because Loop Quantum Gravity and the standard model attempt to answer questions in different problem domains, why anthropogenic global warming denialism doesn't attempt to answer any question in any problem domain. Scientific rejection of anthropogenic global warming assumptions leads to hypotheses that fail to match the behavior of the relevant data.
