So climate sensitivity… is likely somewhere between 1.5 and 4.5 degrees. This result has not changed until today, about 40 years later. And that’s exactly the problem.

Maybe the problem lies in thinking that that is the problem.

Confusing Diabatic and Adiabatic Processes within the Climate Theory:
A Reply to Dr. Roy Spencer’s Blog Article “Giving Credit to Willis Eschenbach”
Ned Nikolov, Ph.D.
Physical Scientist
In a recent blog post, Dr. Roy Spencer at the University of Alabama at Huntsville attempted to criticize and dismiss the importance of our recent discovery about the physical nature of the atmospheric “Greenhouse effect” (Nikolov & Zeller 2017). I normally do not reply to blog articles, but this one reflects a fundamental generic confusion in the current climate theory that is worthwhile addressing for readership clarification. In his blog, Dr. Spencer demonstrated several misconceptions about our work that could be due to either not having read/understood our papers or perhaps an incomplete grasp of thermodynamics. The fact that Dr. Spencer cites a newspaper article about our research instead of the actual published paper may indicate a lack of familiarity with the technical details of our study. These are some key misrepresentations that I spotted in his article:
1. Dr. Spencer incorrectly referred to our main finding as a “theory” when, in fact, it is a discovery based on vetted NASA data extracted from numerous published studies. This empirical pressure-temperature (P-T) function emerged from reported NASA measurements in the process of Dimensional Analysis, which is an objective technique employed in classical physics to derive/extract physically meaningful relationships from observed data.
Even if Ned and Karl just presented the data points on their Ts/Tna vs Pressure graph without any mathematically defined curve, it’d be obvious to most sensible people that there’s a smooth continuum there which strongly resembles other well known pressure temperature relations.
Yes, but they didn’t did they? The smooth continuum is also consistent with the greenhouse effect. The thicker the atmosphere, the more GHG and the greater the temperature difference between the surface and effective radiating layer caused by the lapse rate. So why favour N&Z?
Lol. I’ll take that seriously when you produce your smooth curve plot of Ts/Tna vs [radiative parameter]. Until then, you’re just blustering.
Here are 2 key issues that you must address when trying to defend the radiative “Greenhouse” hypothesis:
Gavin, this is not sensible answer to my 1st question, but a CIRCULAR argument! Can’t you see it? The 342 W m-2 IR back radiation cannot be explained by surface LW emissions, because then the question becomes, where does the 398 W m-2 surface LW radiation come from?
I seem to remember I have already explained this to you at least once. Here is the thought experiment. Imaging a black body in a vacuum containing a 1W constant power heat source. Eventually it will reach an equilibrium temperature at which it radiates 1W out into the (1/n)
vacuum. Now put a thin shell surrounding, but not touching the sphere, of the same blackbody material. The outgoing sphere will heat the shell, and it too will begin to radiate heat until it too reaches thermal equilibrium. Now the shell will radiate equally out into the (2/n)
Hi Brandon, What is the best estimate of the ratio of radiation to space taking place from CO2 relative to H2O?
Dunno Rog. MODTRAN could probably get you in the ballpark. This is CO2-only from 70 km looking down, more what I would expect an actual Nimbus retrieval to look like. http://climatemodels.uchicago.edu/modtran/
Although CO2 absorbs thermal radiation from the Earth, it emits more. Carbon dioxide is in thermal deficit in terms of radiative balance. Nitrogen and oxygen constantly feed CO2 with heat so that it maintains a temperature higher than its radiative equilibrium. CO2 is a coolant.
Question: If I had a container, full with air, and I suddenly decreased the volume of the container, forcing the air into a smaller volume, will it be considered as compression, will it result in an increase in temperature, and why?
Answer on Stack Exchange by Luboš Motl: Yes, it is compression and yes, it will heat up the gas.
If there’s no heat exchange between the gas and the container (or the environment), we call it an adiabatic process. For an adiabatic process involving an ideal gas (which is a very good approximation for most common gases), pVγ is constant where γ is an exponent such as 5/3. Because the temperature is equal to T=pV/nR and pV/pVγ=V1−γ is a decreasing function of V, the temperature will increase when the volume decreases.
Macroscopically, the heating is inevitable because one needs to perform work p|dV| to do the compression, the energy has to be preserved, and the only place where it can go is the interior of the gas given by a formula similar to (3/2)nRT.
We’ve been having a good knockabout on twitter with Patrick Moore concerning Ned and Karl’s Pressure-Insolation theory; their discovery that a simple formula using surface pressure and solar distance will accurately give you the surface temperature on vastly different planets and moons throughout the solar system.
Figure 4: The relative atmospheric thermal enhancement, observed surface T/No -atmosphere T (Ts/Tna ratio) as a function of the average surface air pressure according to Eq. (10a) derived from data representing a broad range of planetary environments in the solar system.
Patrick is a great guy, and a good sport, and has been mostly putting up with Ned’s jibes and arguing his corner. I thought it might help others to understand Ned and Karl’s ideas if we look at a few of the objections Patrick raises and our answers to them.
Earth and climate – an ongoing controversy
Earth’s surface will almost certainly not warm up four or five degrees Celsius by 2100, according to a study released Wednesday which, if correct, voids worst-case UN climate change predictions, reports Phys.org.
A revised calculation of how greenhouse gases drive up the planet’s temperature reduces the range of possible end-of-century outcomes by more than half, researchers said in the report, published in the journal Nature.
“Our study all but rules out very low and very high climate sensitivities,” said lead author Peter Cox, a professor at the University of Exeter.
Pluto probe
Meanwhile the ‘gas only’ theory is under pressure [sic] again, as Pluto’s atmosphere apparently defies expectations.
Pluto may be the only place in the solar system whose atmosphere is kept cool by solid hazes, not warmed by gas, says Science News.
Blame Pluto’s haze for the dwarf planet’s unexpected chilliness. Clusters of hydrocarbons in the atmosphere radiate heat back into space, keeping the dwarf planet cool, a new study suggests.
I got back from Rome last night following the highly successful World Climate Conference. Quite a number of CO2 sceptics gave presentations, which were politely received and discussed by all present. We even made a few converts. Here’s a short interview I made with Ned Nikolov and Karl Zeller where they give their impressions and some insight into their paradigm shifting discovery of the temperature-pressure relationship which holds good across the entire solar system.
Ned and Karl’s two papers are here:
New Insights on the Physical Nature of the Atmospheric Greenhouse
Effect Deduced from an Empirical Planetary Temperature Model
They show that the uplift in temperature on Earth’s surface due to the presence of the atmosphere is not 33K as the current greenhouse theory states but 90K, and is due to atmospheric pressure at the surface, not the back radiation from ‘greenhouse gases’.
We’ve been following Ned and Karl’s work since 2010 here at the Talkshop. They are finally getting heard in a wider forum.
In order to measure Earth’s radiation balance, accurate measurements of both incoming and outgoing radiation have to be made. NASA has been testing a new prototype satellite to measure outgoing radiation from Earth. Up until now, the error on this measurement is estimated to be around +/- 5Wm^2, which means any ‘global warming’ signal is lost in the error margin. This has meant scientists have had to rely on models for estimates.
Ned and Karl have finally got some big exposure to the general public for their paradigm shifting breakthrough in geo and astro-physics. World Net Daily front page stories are read by over a million people. This is a great step forward for recognition of their work.
Study blows Greenhouse Theory out of the water
7-9-2017 By Alex Newman for World Net Daily
BOZEMAN, Mont. – A new scientific paper contends the entire foundation of the man-made global-warming theory – the assumption that greenhouse gases warm the atmosphere by trapping heat – is wrong.
If confirmed, the study’s findings would crush the entire “climate change” movement to restrict CO2 emissions, the authors assert
Some experts contacted by WND criticized the paper, while others advised caution.
Still others suggested that the claimed discovery represents a massive leap forward in human understanding – a “new paradigm.”
The paper argues that concentrations of CO2 and other supposed “greenhouse gases” in the atmosphere have virtually no effect on the earth’s temperature.
Back in late 2011, the Talkshop splashed the story on a ‘Unified Theory of Climate’ developed by PhD physicists Ned Nikolov and Karl Zeller. They set out to show that the ‘greenhouse effect’ is not a phenomenon arising out of the absorption and reemission of outgoing long-wave radiation by the atmosphere (as thought for 190 years), but is a form of compression heating controlled by solar radiation and the total atmospheric pressure at the Earth’s surface. Pressure is in turn a product of the gas mass contained in a column of air above a unit surface area, and the planet’s gravitational effect on that mass.
It’s been a long and treacherous road involving many revisions and refinements of the original study. On several occasions the manuscript was rejected unread, but Ned and Karl have finally got their greatly improved and expanded paper published. This latest version is a tour de force strengthened by the rigors of criticism from an army of peer reviewers at several journals along the way.
Using dimensional analysis (a classical technique for inferring physically meaningful relationships from measured data), they show that the long-term global equilibrium surface temperature of bodies in the solar system as diverse as Venus, the Moon, Earth, Mars, Titan and Triton can accurately be described using only two predictors: the mean distance from the Sun and the total atmospheric surface pressure. This type of cross-planetary analysis using vetted NASA observations has not been conducted by any other authors. It represents the first and only attempt in the history of climate science to assess Earth’s surface temperature in the context of a cosmic physical continuum defined by actual planetary-scale observations. The result is a new insight that planetary climates are independent of the infrared optical depth of their atmospheres arising from their composition, and that the long-wave ‘back radiation’ is actually a product of the atmospheric thermal effect rather than a cause for it.
Tim writes,
Enjoy. When I first came across this paper there was a lot of chuckling, can’t be serious, surely?
Well, I can understand someone wanting to quantify the effect, show the laws, make it a warning for any fools who need saving from themselves, ain’t engineers. I’m afraid this paper goes too far off the deep end, hints at meant seriously. Your opinion might differ.

Harvesting renewable energy from Earth’s mid-infrared emissions
Steven J. Byrnes, Romain Blanchard, and Federico Capasso, School of Engineering and Applied Sciences, Harvard University, Cambridge, MA 02138
Contributed by Federico Capasso, February 3, 2014 (sent for review November 1, 2013)It is possible to harvest energy from Earth’s thermal infrared emis-
sion into outer space. We calculate the thermodynamic limit for
the amount of power available, and as a case study, we plot how
this limit varies daily and seasonally in a location in Oklahoma.We
discuss two possible ways to make such an emissive energy har-
vester (EEH): A thermal EEH (analogous to solar thermal power
generation) and an optoelectronic EEH (analogous to photovoltaic
power generation). For the latter, we propose using an infrared-
frequency rectifying antenna, and we discuss its operating princi-
ples, efficiency limits, system design considerations, and possible
technological implementations.

Research Paper Withdrawal by the Journal Advances in Space Research
Q1: As succinctly as possible, could you tell me why you chose to publish this work under a pseudonym?
A1: We adopted pseudonyms as a measure of last resort as we could not get an unbiased and fair review from scientific journals under our real names. This is explained in more details in the attached letter we sent to the chief editor of the Journal Advances in Space Research (JASR) on Sep. 17, 2015. In brief, our real names became known to the climate-science blogosphere in 2012 when a poster, which we presented at an International Climate Conference in Denver in 2011, became available online and caused broad and intense discussions. When we later tried to publish elements of this poster as separate articles in scientific journals, we discovered that journal editors and reviewers would reject our manuscripts outright after Googling our names and reading the online discussion. The rejections were oftentimes justified by the journals using criticisms outside the scope of the manuscript at hand. On two occasions, journal editors have even refused to send our manuscripts for review after reading the blogs and realizing the broader theoretical implications of our results, although the manuscript itself did not explicitly discuss any new theory. For example, our first paper was rejected 4 times by different journals while submitted under our real names before it was finally accepted by SpringerPlus after submitting it under pseudonyms.
This paper needs discussion.
The Hockey Schtick has an article up on a just published 69 page paper.
The above comparisons indicate that Eq. (10b) rather accurately reproduces the observed variation of mean surface temperatures across a wide range of planetary environments characterized in terms of solar irradiance (from 1.5 W m-2 to 2,602 W m-2), total atmospheric pressure (from near vacuum to 9,300 kPa), and greenhouse-gas concentrations (from 0.0% to over 96% per volume).
http://hockeyschtick.blogspot.co.uk/2015/08/new-paper-confirms-gravito-thermal.html
Now rip the paper apart. What if anything about it is safe?
A few days ago Hockey Schtick brought up Feynman deriving the basic atmospheric gas and temperature profile without mentioning radiation and showing that classical physics fails, quantum mechanics is required.
From Fenyman lectures VOL 1, Chapter 40, showing the contradiction between classic physics and reality, annotated by author. This is one and the same as the ultra-violet catastrophe matter, both needing a quantum physics jump.
Two explanations for one thing might be the food of cats or thought experiments but is not valid in the real world, one planet, although sometimes looking at the state of people I wonder.
Tim writes, someone somewhere reminded me
An anon has reminded me of a critical paper published in the May 1967 issue Journal of the Atmospheric Sciences.
As such in the context of the mid 1960s with little knowledge or computing hardware there ought to be no problem. Unfortunately a number of critical fixed assumptions and of ideas in the paper were ignored for what they were and has formed the basis of the nonsense we have today. The continued correction which typifies science guessing seemed to cease.
Given the Talkshop has many new eyes and opinions since the last mention of this paper a look today is a good move, or at least I think so.
Extracted from paper, one of several choices.

Let’s put this up for discussion as the dominant role of WV often gets buried in all the focus on man-made carbon dioxide emissions.
This posting just points to a very well done page that calculates the relative contributions to the greenhouse effect as used by the AGW thesis, by various gasses. In particular, it includes water vapor. The result is a conclusion that human caused CO2 is not relevant to global temperature. Something I have said before, but without the nice graphs and calculations.
It really is all about the water on our water world.
http://www.geocraft.com/WVFossils/greenhouse_data.html
Water Vapor Rules the Greenhouse System
Just how much of the “Greenhouse Effect” is caused by human activity?
It is about 0.28%, if water vapor is taken into account– about 5.53%, if not.
This point is so crucial to the debate over global warming that how water vapor is or isn’t factored into an analysis of Earth’s greenhouse gases makes the difference between describing a significant human contribution to the greenhouse effect, or a negligible one.
