From Science Matters

By Ron Clutz

This post provides a synopsis of Dr. John Clauser’s Clintel presentation last May.  Below are the texts from his slides gathered into an easily readable format. The two principal takeways are (in my words):

A.  IPCC’s Green House Gas Science is Flawed and Untrustworthy

B.  Clouds are the Thermostat for Earth’s Climate, Not GHGs.

Part I Climate Change is a Myth.

• The IPCC and its collaborators have been tasked with computer modeling and observationally measuring two very important numbers – the Earth’s so-called power imbalance, and its power-balance feedback-stability strength. They have grossly botched both tasks, in turn, leading them to draw the wrong conclusion.
• I assert that the IPCC has not proven global warming! On the contrary, observational data are fully consistent with no global warming. Without global warming, there is no climate-change crisis!
• Their computer modeling (GISS) of the climate is unable to simulate the Earth’s surface temperature history, let alone predict its future.
• Their computer modeling (GISS) is unable to simulate anywhere near the Earth’s albedo (sunlight reflectivity). The computer simulated sunlight reflected power and associated power imbalance error, are typically about fourteen times bigger than the claimed measured power imbalance, and about twenty five times bigger than the claimed measured power imbalance error range.
• The IPCC’s observational data are wildly self-inconsistent and/or are fully consistent with no global warming.
• The IPCC’s observational data claim an albedo for cloudy skies that is inconsistent with direct measurements by a factor of two. Alternatively, their data significantly violate conservation of energy.
• Scientists performing the power-balance measurements admit that the available methodologies are incapable of measuring a net power imbalance with anywhere near the desired accuracy. This difficulty is due to huge temporal and spatial fluctuations of the imbalance, along with gross under-sampling of the data.
• The observational data they report are self-inconsistent and are visibly dishonestly fudged to claim warming. The fudged final reported values, herein highlighted and exposed, are an example of the proverbial proliferation of bad pennies.
• NOAA’s claims that there is an observed increase in extreme weather events are bogus. Their own published data disprove their own arguments. A 100 year history of extreme weather event frequency, plotted frontwards in time is virtually indistinguishable from the same historical data plotted backwards in time.
• In Part II, I present the cloud-thermostat feedback mechanism. My new mechanism dominantly controls and stabilizes the Earth’s climate and temperature. The IPCC has not previously considered this mechanism. The IPCC ignores cloud-cover variability.

The IPCC’s two sacred tasks – both botched!

1. The IPCC and its collaborators have been tasked with computer modeling and observationally measuring two very important numbers – the Earth’s so-called power imbalance, and its power-balance feedback-stability strength.
2. The Earth’s net power imbalance is its sunlight heating power (its power-IN), minus its two components of cooling power – reflected sunlight and reradiated infrared power (its power-OUT).
3. Based on their claimed power imbalance and global-warming assertion, the IPCC and its collaborators assemble a house of cards argument that forebodes an impending climate change apocalypse/ catastrophe.
4. Additionally, the IPCC and its contributors calculate the strength of naturally occurring feedback mechanisms that presently stabilize the Earth’s temperature and climate
5. They claim only marginal effectiveness for these mechanisms, and correspondingly assert that there is a “tipping point”, whereinafter further added greenhouse gasses catastrophically cause what amounts to a thermal-runaway of the Earth’s temperature.
6. The IPCC scapegoats atmospheric greenhouse gasses as the cause of global warming, and further mandates that trillions of dollars must be spent to stop greenhouse gas release into the environment with a so-called “zero-carbon” policy.
7. The IPCC also mandates multi-trillion dollar per year geoengineering projects including Solar Radiation Management Systems to stabilize the Earth’s climate and CO2 capture projects to reduce the atmospheric CO2 levels.
8. I assert that the IPCC and its contributors have not proven global warming, whereupon their house of cards collapses.
9. My cloud thermostat mechanism’s net feedback “strength” (the IPCC’s 2nd sacred task to estimate) is anywhere from -5.7 to -12.7 W/m2/K (depending on the assumed cloud albedo, 0.36 vs. 0.8), compared to the IPCC’s botched best estimate for their mechanisms of -1.1 W/m2/K. My mechanism’s overwhelmingly dominant strength confirms that it is the dominant feedback mechanism controlling the Earth’s climate.
10. Correspondingly, I confidently assert that the climate crisis is a colossal trillion-dollar hoax.

The IPCC’s computer modeling uses flawed physics to estimate the Earth’s temperature history

• The above graph is copied from [AR5, (IPCC, 2013) Fig 11.25].
• It shows the IPCC’s CMIP5 computer modeling of the Earth’s temperature “anomaly”. The various computed curves display the earth’s predicted (colored) and historical (gray) “temperature anomaly”.
• The solid black curve is the observed temperature anomaly
• Note that all 40+ models are incapable of simulating the Earth’s past temperature history. The total disarray and total lack of reliability among the CMIP5 predictions was first highlighted by Steve Koonin (former White House science advisor to Barack Obama) in his recent book- Unsettled? What climate science tells us, what it doesn’t, and why it matters.
• Something is obviously very wrong with the physics incorporated within the computer models, and their predictions are totally unreliable.
• Albedo is the fraction of sunlight power that is directly reflected by the Earth back out into space (OSR=100 W/m2 portion of power-OUT)

• The above Figure, copied from Stephens et al. (2015), shows the IPCC’s CMIP5 computer modeling (colored curves) of the Earth’s mean annual albedo temporal variation. The solid black curve is the Earth’s albedo measured by satellite radiometry. (The variation is not sinusoidal.)
• The added scale shows the associated reflected sunlight power. It assumes a constant solar irradiance – 340 W/m2
• Note that the IPCC’s computer modeling is grossly incapable of simulating the observed Earth’s reflected power, and especially incapable of simulating that power’s dramatic temporal fluctuation.
• The actual power’s annual variation is actually much greater than is shown by this Figure by about 18 W/m2, due to the ellipticity of the Earth’s orbit and the associated sinusoidal temporal variation of the so-called solar constant.
• Despite more than 10 W/m2 gross errors in the computer simulation’s calculated reflected power, as is shown on the Figure, the IPCC [AR6 (2021)] still claims that it has computer simulated and precisely measured this power, yielding an imbalance that is equal to 0.7 ± 0.2 W/m2 – Huh?

The IPCC’s observational data are consistent with NO global warming

• Power-IN is the sunlight power incident on the Earth. The IPCC and climate scientists call it Short Wavelength (SW) Radiation. It is about 340 Watts per square meter of the Earth’s surface area. (It is not actually constant, but varies ± 9 W/m2.)
• Power-OUT has two components:
• One component is the sunlight energy that is directly reflected by the Earth back out into space, whereinafter it can no longer heat the planet. That component is claimed by the IPCC to be about 100 W/m2.
• The other component is the far-infrared heat radiated into space by a hot planet. It is claimed to be about 240 W/m2. The IPCC calls the far-infrared heat radiation component, Long Wavelength (LW) Radiation.
• Measuring the power imbalance consists of measuring power-IN, measuring power-OUT and subtracting. Simple enough? Not really. The problem is that power-IN, and power-OUT are huge numbers, and that the difference between them is miniscule – 0.2% of power-IN. That miniscule difference is the net imbalance that is sought, both experimentally and theoretically.

Unfortunately, it is so small that it is very difficult, if not impossible, to measure to the desired accuracy, 0.1 W/m2, or 0.03% of power-IN. It is much tougher to measure when power-IN and power-OUT are both also hugely varying in a seemingly random irreproducible fashion. Large variations occur both in time and in space over the surface of the Earth. As noted in a previous slide, this grossly under-sampled fluctuation is about 28 W/m2, compared with the IPCC’s claimed imbalance, 0.7 ± 0.2 W/m2.
• A variety of methods has been employed to measure these powers. They include satellite radiometry, (the ERBE, and CERES Terra and Aqua satellites), ocean heat content (OHC) measured using the ARGO buoy chain and XBT water sampling by ships, and finally by ground sunlight observations using the Baseline Surface Radiation Network (BSRN).
• The various measured values are all in wild disagreement with each other. Importantly, none of the reported data actually show a convincing net warming power imbalance. Importantly, much of the reported data are totally fudged in a manner that dishonestly changes them from showing no warming to showing warming!

Critiques of Power-Flow Diagrams by Trenberth et al. (2010, 2014)

• Satellites measure the Top of Atmosphere energy balance, while Ocean Heat Content data apply to the surface energy balance. One may legitimately mix power-flux data at the two different altitudes, if and only if one fully understands all of the power-flow processes in the atmosphere that occur between the surface and the Top of Atmosphere. If the latter requirement is not true, then one ends up with an “apples to oranges” comparison.
• Trenberth et al. (2010, 2014) are highly critical of Loeb, Stephens, L’Ecuyer, and Hansen’s claimed “understanding” of the associated connection between the power flows at these two altitudes.
• Trenberth and Fasullo (2010) point to a huge “missing energy” indicated by the difference between the satellite data and the OHC data power-imbalance calculations, and specifically ask “Where exactly does the energy go?”
• Hansen et al. (2011) dismiss Trenberth and Fasullo’s alleged missing energy as being simply due to satellite calibration errors.
• Trenberth Fasullo and Balmesada (2014) further note that despite various considerations of the surface power balance, significant unresolved discrepancies remain, and they are skeptical of the power imbalance claims.
• In effect, Trenberth et al. are the earliest “whistle blowers” to the above-mentioned data fudges.

Part I –The Climate Change Myth– Conclusions

1. The IPCC and its contributors claim the Earth has a net-warming energy imbalance. I show here that those claims are false.
2. The IPCC bases its claims on computer modeling of the Earth’s atmosphere, and on observational data from a variety of observational modalities. Both the computer models and the observational data are grossly flawed, and fudged.
3. The IPCC’s computer modeling and its predictions are totally unreliable. There is something clearly very wrong with the physics incorporated within these computer models. Since the computer models can’t even explain the past, why should anyone trust their prediction for the future?
4. Not one of the observational modalities for measuring the Earth’s power imbalance convincingly shows net global warming.
5. I show where various observers and the IPCC have dishonestly fudged their reported data, and have dishonestly changed it from showing No Warming, to showing Warming. Crucially important data fudges are revealed here and highlighted in red. If you don’t believe me, check my arithmetic.
6. The IPCC and NOAA further claim that the purported power imbalance has already caused an increase in dangerous extreme weather events. NOAA’s own data disprove their own claims.
7. I thus offer Great News. Despite what you may have heard from the IPCC and others, there is no real climate crisis! The planet is NOT in peril!
8. The IPCC’s (and NOAA’s) claims are a hoax. Trillions of dollars are being wasted.

Part II – The cloud thermostat 

1. So what is really happening? Why is the earth’s climate actually as stable as it really is?
2. The cloud thermostat mechanism is clearly the overwhelmingly dominant climate controlling feedback mechanism that controls stabilizes the Earth’s climate and temperature. It thereby prevents global warming and climate change.
3. The cloud-thermostat mechanism provides very powerful feedback that stabilizes the Earth’s climate and temperature. It great strength obtains from the observed large fluctuation of the Earth’s power imbalance.
4. The mechanism gains its strength from the Earth’s observed very large cloud-cover variation. The power imbalance is actually observed to be continuously strongly fluctuating by anywhere between 18 to 55 W/m2.
5. Clouds modulate the outgoing Shortwave power and therefore control the Earth’s power imbalance, minimally with a 18 W/m2 available power range (ignoring the added 18 W/m2 solar-constant variation), which is minimally 26 times the IPCC’s 0.7 W/m2 claimed power imbalance, and 45 times the IPCC’s ± 0.2 W/m2 power imbalance error range.
6. The above numbers use the IPCC’s assumed data parameters. With more realistic assumptions, the cloud-thermostat mechanism controls the Earth’s power imbalance with a 73 W/m2 available power range, which is 100 times bigger than the IPCC’s 0.7 W/m2 claimed power imbalance, and 180 times bigger than the IPCC’s ± 0.2 W/m2 power-imbalance total error range.
7. This seemingly random fluctuation of the power imbalance is not random at all, but is actually a crucial part of a thermostat-like feedback mechanism that controls and stabilizes the Earth’s climate and
temperature. It is observed by King et al. (2013) and by Stephens et al. (2015) to be quasi-periodic,
8. Just like the thermostat in your home, the power-imbalance is never zero. The furnace or AC is always either ON or OFF. The thermostat simply modulates the heating/cooling duty cycle.

Features of the cloud thermostat mechanism

1. In preparation for the introduction of this model, I first describe important, underappreciated, but conspicuous properties of clouds – their variability and their strong reflectivity of sunlight (SW radiation).
2. I show that the cloud-thermostat mechanism involves the dominant (73%) use of sunlight energy by the planet.
3. I show that when the cloud-thermostat mechanism is viewed as a form of climate-stabilizing negative feedback, it is by far the most powerful of any such mechanism heretofore considered.
4. The IPCC estimates that the net stabilizing feedback strength or the Earth’s climate, including the destabilizing feedback strength of greenhouses is about -1 W/m2/ºC.
5. I show that the cloud thermostat feedback increases the net natural stabilizing feedback strength to about anywhere between -7 W/m2/ºC and -14 W/m2/ºC, depending on the assumptions used.

There are 5 important take-home messages to be gleaned from these satellite photographs.

1. Clouds reflect dramatically more sunlight than the rest of the planet does!
2. Clouds of all types appear bright white!
3. The photos (along with a large number of careful measurements) strongly suggest that the average cloud reflectivity (of sunlight) is about 0.8 – 0.9. (For comparison, white paper has a reflectivity of ≈ 0.99.) [Wild et al.(2019) claim that cloud reflectivity is 0.36.]
4. The rest of the planet appears much darker than the clouds. The average reflectivity of land (green and brown areas) and ocean (dark blue areas) is ≈ 0.16.
5.Cloud coverage area is highly variable over the Earth.

What does sunlight mostly do when it reaches the Earth’s surface?

• It is commonly believed that sunlight that is absorbed by the Earth’s surface simply warms the surface. That may be true over land. But land represents only about 30% of the surface.
• Oceans cover 70% of the Earth’s surface. Correspondingly, about 70% of incoming sunlight falls on the oceans. Virtually all of the Earth’s exposed water surface occurs in the oceans.
• Following the AR6 power-flow diagram, 160 W/m2is absorbed by the whole Earth, meaning that roughly 70% X 160 = 112 W/m2 is absorbed by oceans.
• The AR6 power-flow diagram indicates that 82 W/m2 is used for evaporating water, and not for heating the surface.
• Since clouds are mostly produced over the oceans (because that’s where the exposed water is), then 82/112 = 73% of the input energy absorbed by the Earth’s oceans is used, not for warming the Earth, but instead simply for making clouds.

How does the cloud thermostat work?

1. Recall that the IPCC’s AR6 power-flow map asserts that 73% of the input energy absorbed by the Earth’s oceans is used, not for warming the Earth, but instead simply for evaporating seawater and making clouds, rather than for raising the Earth’s surface temperature. Recall that the Earth has a strongly varying cloud cover and albedo.
2. Temperature control of the Earth’s surface by this mechanism works exactly the same way as does a common home thermostat. A thermostat automatically corrects a structure’s temperature in the presence of varying modest heat leaks. For the earth, the presence of significant CO2 in the earth’s atmosphere, manmade or not, provides, in fact, a very small heat leak (at most, about 2 W/m2).  Note that, just like the Earth, the power imbalance for a thermostatically controlled system is never zero. It is always fully heating or fully cooling.
3. How does the cloud thermostat work? When the Earth’s cloud-cover fraction is too high, then the earth’s surface temperature is too low. Why? Clouds produce shadows. Cloudy days are cooler than sunny days. A high cloud-cover fraction equals a highly shadowed area. With reduced sunlight reaching the ocean’s surface and lower temperature, the evaporation rate of seawater is reduced. The cloud production rate over ocean (70% of the earth) is low because sunlight is needed to evaporate seawater. The earth’s too-high cloud-cover fraction obediently starts to decrease. Very quickly, cloud-cover fraction decreases, the temperature increases. The Earth’s cloud-cover fraction is no longer too high. Equilibrium cloud cover and temperature are restored.
4. When the Earth’s cloud-cover fraction is too low, the surface temperature is then too high, then the reverse process occurs. With low cloud cover, lots of sunlight reaches the ocean surface. Increased sunlit area then evaporates more seawater. The cloud-production rate obediently increases and the cloud-cover fraction is no longer too low . Equilibrium cloud cover and temperature are again restored.
5. Depending of one’s assumption regarding cloud reflectivity (albedo), the cloud thermostat mechanism has anywhere between 18 and 55 W/m2 power available from cloud-fraction variability to overcome a wimpy 0.7 W/m2 heat leak (allegedly blamed on greenhouse gasses) and to stabilize the Earth’s temperature, no matter what the greenhouse gas atmospheric concentration is!
6. These two fluctuating opposing processes, when in equilibrium, provide an equilibrium cloud-cover fraction, and an equilibrium average temperature. The earth thus has a built in thermostat!

Feedback strength of the cloud thermostat mechanism

1. The resulting cloud-thermostat mechanism’s feedback parameter is now readily evaluated under the two scenarios associated with two choices for cloud albedo. The details of the calculation are shown in Appendix D.
2. Using the AR6 choice for cloud albedo, αClouds = 0.36, we have λClouds ≈ – 5.7 W/m2 K, which is 1.7 times larger than (the misnamed) λ Planck , heretofore the strongest feedback term.
3. Alternatively, using the more reasonable choice for cloud albedo, αClouds = 0.8, we have λClouds ≈ -12.7 W/m2 K, which is 3.8 times larger than (the misnamed) λPlanck.
4. These values are plotted as an extension of the AR6 Figure 7.1, which shows the feedback strength for various mechanisms. The total system strength is shown in the left-hand column.
5. Viewed as a temperature-control feedback mechanism, in either scenario, the cloud thermostat has the strongest negative (stabilizing) feedback of any mechanism heretofore considered.
6. It very powerfully controls and stabilizes the Earth’s climate and temperature.

Part II – Conclusions

1. I have introduced here the cloud-thermostat mechanism. It is clearly the overwhelmingly dominant climate controlling feedback mechanism that controls stabilizes the Earth’s climate and temperature. It thereby prevents global warming and climate change.
2. The IPCC’s 2021 AR6 report (p.978) claims that climate stabilizing natural feedback mechanisms have a net (total) stabilizing strength of -1.16 ± 0.6 W/m2/K. My cloud feedback mechanism has a net stabilizing strength of anywhere between -5.7 to -12.7 W/m2/K, depending of one’s assumptions regarding the albedo of clouds.
3. My cloud thermostat mechanism provides nature’s own Solar Radiation Management System. This mechanism already exists. It is built in to nature’s own cloud factory. It works very well to stabilize the Earth’s temperature on a long term basis. And, it is free!

“Recommendations for policy makers”

1. There is no climate crisis! There is, however, a very real problem with providing a decent standard of living to the world’s now enormous population. There is indeed an energy shortage crisis. The latter is being unnecessarily exacerbated by what, in my opinion, is incorrect climate science, and by
government’s associated incorrect muddled response to it.
2. Government and business are currently needlessly spending trillions of dollars on efforts to limit the greenhouse gasses, CO2 and CH4, in the Earth’s atmosphere.
3. CO2 and CH4 are not pollutants. They must be removed from every list of defined pollutants. They have a negligible effect on the climate. Trillions of dollars can be saved by this one simple measure alone! Additionally, the CO2 Coalition points out that atmospheric CO2 is actually beneficial.
4. I recommend that all efforts to limit environmental carbon should be terminated immediately! Trillions of dollars can be saved by eliminating carbon caps, carbon credits, carbon sequestration, carbon footprints, zero-carbon targets, carbon taxes, anti-carbon policies and fossil-fuel limits, in energy policy and elsewhere.
