The IPCC is Wrong

As a factor in Global Warming, increases in the atmospheric concentration of CO2 have been, and will continue to be, largely irrelevant.

Summary

The following are the basic principles and assumptions underlying the calculations set out in this paper:

1. The heating provided by CO2 is radiant heating and for purposes of this paper, when calculating the increase in heating that is a result of the buildup of CO2 in the atmosphere the only source of any increase in heating in these calculations is CO2 and the Water Vapor Feedback Effect it creates.

2. In order to maintain a given temperature, the power of the radiant heating absorbed by the Earth’s surface must at least equal the power of the thermal radiation emitted by the surface.

3.The total heating power, ΔF,  required to drive a given increase in the temperature of the surface of Land can be determined as,

 ΔF =  [(TLo + ΔTL) / TLo)4 – 1] × RULo  / Eff

 Where:       TLo is the initial average temperature of Land                                                                               

                     ΔTL is the change in the average surface temperature of Land,

                     RULo is the initial Up Radiation at TLo

                   Eff is the percentage of an increase in Total Heating that heats the Earth’s Land     surface.

The increase in heating power, ΔRadCO2, caused solely by an increase in the concentration of CO2 from the initial concentration, C0 to C, in ppmv, is determined by this formula –

ΔRadCO2 = 5.35 × ln (C / C0) (w/m2),

which means that there is but one result for ΔRadCO2 for a given change in concentration.

4. The increase in heating from the Water Vapor Feedback Effect provided by an increase in average temperature, ΔTCO2, resulting solely from the increase in heating from a buildup in CO2 is determined by this formula:

ΔWV = 1.6 ×ΔTCO2  (w/m2)

5. The Maximum increase in heating power received at the surface cannot exceed the sum of the results of the calculations set out in statements 4 & 5.

6. The Maximum average increase in Land temperature in degrees Fahrenheit, ΔTL resulting from of the calculations set out in statements 4 & 5 of ΔRadCO2 and ΔWV is determined by this formula as –

ΔTL = TLo × [(1 + Eff ×WV + ΔF) / NHLo)1/4– 1]

where:

NHLo is the initial Net Heating of the Land surface in watts per square meter.

7. One cannot determine the increase in Average Global Temperature based upon a change in heating because the surface temperature change response of Land and the Oceans to an increase in heating is significantly different. However, it is possible to determine the increase in Average Global Land Temperature based upon a change in heating and then estimate the change in Average Global Temperature.

8. The Maximum increase in average temperature cannot exceed the increase in temperature caused by the result of the calculations set out in statement 6.

The following are the results of the applications of these principles:

A. The change in the Average Global Temperature for Land between 1880 and 2002 was 2.6oF. To effect such an increase requires an increase of 13.8 w/m2 in total Average Heating Power. The Maximum total increase in total Average Heating Power that the buildup of COover this period could have effected is 1.6 w/mand the Maximum increase in the Average Global Temperature for Land that the buildup of CO2 over this period could drive cannot exceed 0.3 oF.

B. CO2 is not THE cause nor is it the primary cause of Global Warming

C. The Maximum increase in Average Global Temperature that a doubling of the concentration of CO2 from 400 to 800 ppmv can effect is 0.8oF. The IPCC’s predictions of 3.4oF to 7.9oF are 325% to 900% too high and this would require an increase in heating of 800% to 900% greater than that determined in accordance with the calculation set out in statement 3 above.

D. The IPCC is simply wrong.

Background

I have no direct, or indirect, links or ties to any business or investment that has any interest, whatsoever, in this matter. I have neither sought, been offered or received any funding, benefit or any form of consideration or promises to prepare this work – none. This has all been an independent pursuit of truth.

At the time, of the award of the 2007 Nobel Peace Prize to former Vice President Albert Gore and the Intergovernmental Panel on Climate Change (the IPCC) which was accepted on behalf of the IPCC by Dr. Pachauri, then Chair of the IPCC, I was honored to accept an invitation from a colleague to attend a gathering to celebrate the granting of this award, in Oslo.

I should also note that my academic training is not in meteorology or climate studies but this is also true, not only for Al Gore, but Dr. Pachauri as well. And, unlike both, for several years I was part of a team of scientists designing vehicles for the vacuum of space and calculating the extreme rates of heating to which they are exposed as they slammed into the atmosphere of Earth or Venus. In the case of the probes into the planet Venus this work took into account radiative heating.

In terms of absorbing and emitting radiative heat, our planet is just another object in space, with sufficient mass to maintain an atmosphere that contains a small percentage of gases that both absorb and reradiate infrared (IR) radiation, the Greenhouse Gases (GHG).

With a basic grasp of physics, radiative heating and thermodynamic principles, a determination of the Maximum increase in the Average Global Temperature (the Upper Bound) that a buildup in the concentration of CO2 can effect is possible. Otherwise, the only option is to rely on the purported “experts” which I did for a couple of decades.

I sat there the night of this celebration listening to the speakers with the belief that Global Warming had occurred and hoping that at this celebration there would be an explanation as to why there was this exclusive focus on an atmospheric increase of ~ one part per million per year or one part per ten thousand over a century, of CO2, the effect of which is merely logarithmically proportional to increases in concentration over 290 ppmv, (at this level, a 10% increase in concentration results in a 1.7% increase in heating power[1]) and on a molecule-for-molecule is less effective as a Greenhouse Gas than the primary Greenhouse Gas, Water Vapor, which, on average, is present in the atmosphere at levels, and varies by factors, that are an order of magnitude greater than that of CO2 and, …..what this had to do with peace?

There was no presentation that demonstrated how an inconsequential change in such a minor component of the atmosphere could be responsible for Global Warming. Instead, what I heard were assumption based conclusions, summaries of the results of unexplained computer models, political speak and predictions of a parade of horribles, which may or may not be realistic, but could be the result of warming, irrespective of the cause.

That night, as the advocates for this belief played on our fears of Global Warming including a totally irrelevant and nonsensical analogy to horrible conditions on planet Venus, something I knew a little about, at the same time they appeared to be seeking to impute an unquestioning sense of guilt for all of Humankind stemming from having so benefitted from the massive consumption of fossil fuels along with a need to make amends by paying whatever it takes to stem the tide of Carbon buildup and minimize the effects of various potential doomsday scenarios, (reminded me of some preachers, “Atone for your sins or suffer hellfire and brimstone for eternity.”). For the first time, I began to wonder, based on the lack of scientific proof offered at a celebration of a Nobel Prize on the work of the role of CO2 in Global Warming, whether, and if so, why, the world was being taken in, misdirected into thinking that CO2 was THE or the primary cause of Global Warming.

Since then, my question – why the exclusive focus on such an inconsequential component of the atmosphere – went unanswered. Having read many justifications from those who make claims that Global Warming was/is caused solely by increases in the concentration of CO2. They basically boil down to:

1. Correlations of temperature increases with increases in the concentration of CO2;

2. Formulations/approximations that do not comply with the basic laws of physics, ignore the actual effects of heating and, at times, either alone or together with a theoretical, inflated and incorrect Water Vapor Feedback Effect formulation, substantially overstate the increases in temperature that the buildup in the concentration of CO2 can effect; and,

3. Determining that CO2 must be THE cause, because, if one does not include subsequent increases in the concentration of CO2 since the 1800s in the climate change computer models, these models do not show global warming, Lindzen (2007), but only do when subsequent increases in the concentration of CO2 are included (and then they overstate the increase in temperature, suggesting they are premised on the above formulations[2]) which, of course, assumes that these models are correct; they are not; See Gray (2012);

concluding, therefore, that Global Warming has been driven by the buildup of CO2 since the advent of industrialization.

These responses are all based upon the assumption that the buildup of CO2, alone was responsible for Global Warming.

When it comes to CO2, I wondered, rather than make assumptions, why not simply calculate the Maximum incremental heating that an increase in the concentration of atmospheric Carbon Dioxide can provide and the resulting MAXIMUM temperature increase? It is not difficult.

The average temperature of the surface cannot exceed the MAXIMUM average temperature that the Net Heating can effect. Therefore, if one knows the additional net-heating that a buildup in CO2 can cause, including the Water Vapor Feedback Effect, one can calculate the theoretical MAXIMUM increase in the Average Global Land temperature that the buildup in the concentration of CO2, alone, can effect.

While I could find many papers that calculated the increase in heating, radiative forcing, that increases in the concentration of CO2 could drive and then draw conclusions about the relationship to net surface temperatures based on the assumption that these temperature changes were caused by increases in the concentration of CO2, I could find very few analyses that went beyond the calculation of incremental heating.

There were only a few that purported to explain how to calculate the increase in the Average Global Temperature resulting from increases in the concentration of CO2. Of these there were only a few that calculated the historical increase and then only at the conclusion of the time period in question. (e.g. “Between 1880 and 2002 the temperature increase caused by the prior buildup of CO2 was equal to X.”) I found no studies for the changes in the temperature of Land caused by CO2, which for the reasons set out below, enables the most straightforward comparison.

My back of the envelope calculations for the heating power required from increases in the concentration of CO2 to effect the actual temperature increases over time called all of the IPCC’s conclusions about the role played by CO2 in Global Warming, into question. Therefore, I looked into this issue in greater detail, which resulted in this paper, in which, will calculate the MAXIMUM (not the precise) increase in average temperature that the buildup of CO2 can effect.

How to Calculate the Power and Maximum Temperature Increase Caused by an Increase in the Concentration of CO2

The Earth constantly emits thermal infrared radiation (IR) which I will term “Up Radiation”, RU.

The sole source of heating of the Earth’s surface is the net radiant heating absorbed from the Sun and the “Back Radiation” from GHG, the Net Heating.

If the average surface temperature is constant for a period of time, this means that the average power per square meter of the Net Heating, NH, is at least equal to the power per square meter of the average Up Radiation. Therefore,

Net Heating, NH = RU

Comparing Land to Ocean, the temperature of the surface of Land is far more responsive to the same changes in Net Heating. See Figure 1, below.clip_image004[4]

Figure 1. Average, Ocean and Land Temperature Anomalies (NOAA 2010)

Due to the percentage that goes into subsurface heating as a result of the thermal diffusivity of the Oceans, the surface temperature of the Oceans is not as responsive to the same radiant heating as Land.

Thus, changes in Average Global Land Temperature is a far better gauge of the changes in Net Heating than changes in the Average Global Ocean Surface Temperature or Average Global Temperatures (Land & Ocean, above), which includes the Oceans comprising 70.57% of the Earth’s surface. Therefore, I will use changes in Land temperature as a gauge.

The Up Radiation per square meter of the Land surface, RUL is equal to εσTL4 (Luciuk) where, ε is emissivity, a dimensionless constant between 0 and 1 that determines the efficiency of a body to radiate and absorb energy, which in this paper, for the surface of Land is assumed to be 1; σ is the Stefan-Boltzmann constant, 5.40×10-9 w/m2 T-4 and TL is the Global Average Land temperature in degrees Rankine.

RUL = εσTL4

At a constant average surface temperature, Net Heating, NHL = RUL, and, initially, NHLo = RULo

To maintain a given temperature, the Net Heating, NHL must equal the Up Radiation

NHL = RUL = εσTL4

Then, 

NHLN / NHLo = NHLN / RuLo = εσTLN4 / εσTLo4 = TLN4 / TLo4

 Since,

TLN  = TLo + ΔTL

And

NHLN = NHLo + ΔNHL

The increase in Net Heating power, ΔNHL, required to support this increase in temperature is,

ΔNHL = RULo × [(TLo + ΔTL) / TLo)4 – 1]

 Where ΔTL is the change in the average surface temperature of Land, and

                                RULo is the initial Up Radiation at TLo

The minimum change in Total Heating power, ΔF,  required to drive a given increase in the temperature of the surface of Land can be determined as, ΔNHL / Eff 

ΔF = ΔNHL / Eff = [(TLo + ΔTL) / TLo)4 – 1] × RULo / Eff

So for an increase of 2.6o from an initial temperature of 507.9oR and an initial Up Radiation of 360 w/m2, for this change in temperature, the minimum change in Total Heating, ΔF, required to effect this is,

 ΔF =  [(507.9 + 2.6) / 507.9)– 1] × 360  / 0.55 = 9.5 w/m2

If there is a change in Net Heating, ΔNH

 

This will result in a change in temperature, ΔT and the new temperature, TLN

TLN = TLo + ΔTL

The new Up Radiation, RULN, is equal to the initial Up Radiation, RULo plus the change in Up Radiation, ΔRuL.

RULN = RULo + ΔRuL

and, as noted above, where NHn is the New Net Heating,

RULN = NHn

NHis equal to the initial Net Heating, NHo, plus the change in Net Heating, ΔNHL. Therefore,

RULN = NHn = NHo +  ΔNHL = RULo + ΔRuL

Since, NHLo= RULo

 ΔNHL = ΔRuL

Further, given that

RULN = εσTLN4

Therefore, the ratio RULN / RULo

RULN / RULo = εσTLN4/ εσTLo4 = TLN4/TLo4

Since, RULN = RULo + ΔRuL

This ratio can then be written as,

(RULo + ΔRuL) / RULo = TLN4/TLo4

Given that ΔRuL = ΔNHL, then,

(RULo + ΔNHL) / RULo = TLN4/TLo4

And given that TLN = TLo + ΔTL, then,

(TLo + ΔT)4 /TLo4 = (RULo + ΔNHL) / RULo

Taking the fourth root of each side

(TLo + ΔTL)/TLo = [(RULo + ΔNHL) / RULo]1/4

Then solving for ΔTL

ΔTL = TLo × [(RULo + ΔNHL) / RULo]1/4– TLo

or,

ΔTL = TLo × [(RULo + ΔNHL) / RULo)1/4– 1]

The next step is to determine the increase in Net Heating as a result of an increase in the concentration of CO2.

The IR frequency band within which atmospheric CO2 can absorb IR radiation is nearly saturated, meaning that, today, the pre-existing concentration of CO2 effectively absorbs almost all of the Up IR Radiation that fall within this narrow band. In addition, this band overlaps with absorption band for Water Vapor. The consequence, there is very little IR radiation remaining that falls within this band that added CO2 can absorb. Therefore, the absorption within this band is not directly proportional to increases in the concentration of CO2.

The effect of this IR band saturation can be accurately modeled on the University of Chicago’s Modtran computer model, climatemodels.uchicago.edu/modtran/modtran.doc.html, for simulating the absorption and emission of infrared radiation in the atmosphere, including the effect of variations in the concentration of CO2.[3] This computer model was first developed for the U.S. Air Force and has been verified by satellite measurements. It is a very accurate way of determining the effects of band saturation on the ability of changes in the concentration of CO2 to change IR Back Radiation. However, this model is both change in concentration and geographically specific. In order to gauge the heating effect of changes in the concentration of CO2, each change in the concentration requires a separate computer run.

Instead, in this paper, the increase in heating from an increase in the concentration of CO2 in watts per square meter, ΔRadCO2, is calculated, in accordance with the IPCC’s formula as:

ΔRadCO2 = 5.35 × ln (C / C0)

where, C is the CO2 concentration in parts per million by volume at the later date, ppmv and, C0 is the concentration at the date from which the change is being measured, in ppmv,

not because it is correct[4] (it overstates the heating power from the increase in concentration) but because it is the only consensus model I have found and will clearly result in the calculation of the MAXIMUM temperature increase a buildup of CO2 can cause.

Knowing that the increase in heating from the buildup of CO2,  alone, ΔNHLCO2 is equal to the percentage of ΔRadCO2 that goes into heating the Land, Eff, and substituting Eff × ΔRadCO2 for ΔNHLCO2, the change in temperature caused solely by an increase in heating from the buildup in the concentration of CO2, can be expressed as,

ΔTLCO2 = TLo × [(RULo + Eff × ΔRadCO2) / RULo)1/4– 1]

or,

ΔTLCO2 = TLo × [(1 + Eff × ΔRadCO2 / RULo)1/4– 1]

Set out in Table 1, below, are my estimates of the key components of the Earth’s energy budget in 1880 and 2002 for Land.

Table 1

Earth’s Average Global Land Heating Budget[5] for 1880 and 2002, (w/m2)

Land 1880 2002
Total Heating 471 485
Up Radiation Land, RUL or Net Heating Land, NHL 360 367
Solar Radiation 159 161
Back Radiation from GHG 312 324
Evaporative Power, Land 13 13
Thermal Convection Land 99 105

This heating budget for Land for 1880 and 2002 together with the Average Global Temperature for Land in these respective years sets a base from which one can calculate the MAXIMUM temperature changes increases in the concentration of CO2 can effect.

As both the Sun and the GHG heat the surface of the Earth they simultaneously drive evaporation, subsurface warming and convection. The power that goes into evaporation, subsurface warming and convection cannot go into heating of the surface. In this paper, Net Heating is defined as the percentage of Total Heating that does not go into the evaporation, sub surface warming and convection. The Effective heating percentage (“Eff”) is defined as the percentage of Total Heating that heats the Earth’s Land surface. Referring to Table 1, for Land, about 53% of the Total Heating of the Earth results in the Net Heating of the surface.

To be conservative, Eff is set at 55%. Therefore, to determine the Net Heating Power,

Net Heating Power = Eff × Total Heating = 0.55 × Total Heating

This increase in heating and temperature will gives rise to an increase in evaporation, which will in turn increase the GHG and give rise to an additional increase in temperature, determined as follows:

The increase in Average Global Temperature can be determined from the increase in Land Temperature. It is approximately equal to the increase in Average Global Land Temperature multiplied by the ratio of the increase in Average Global Temperature between 1880 and 2002,1.4oF to the increase in Average Global Land Temperature over this period 2.6oF = 1.4oF / 2.6 = 0.56

The Maximum measured and estimated long term Water Vapor Feedback is 1.6 w/m2 per degree Fahrenheit change in Average Global Temperature Dessler (2014).[6]

Thus, the heating caused by the Water Vapor Feedback Effect, ΔWVCO2, as a result of an increase in Average Global Land Temperature, ΔTLCO2, in degrees Fahrenheit, can be expressed as:

ΔWVCO2 = 0.56 × 1.6 × ΔTLCO2

Taking into account the Water Vapor Feedback Effect, WVCO2, the MAXIMUM increase in net heating of the Land, ΔNHL, that can be caused by an increase in the concentration of CO2 from a given date can be determined as follows:

The Net Heating Increase, ΔNHL = Eff × (ΔRadCO2 + ΔWVCO2)

Thus, this is how the MAXIMUM Average[7] Global Land temperature increase can be calculated for a buildup of CO2.

ΔTL = TLo × [(1 + Eff × (ΔWVCO2 + ΔRadCO2) / RULo)1/4– 1]

So, for 1880, which is a starting point commonly used,

C0 is 291 ppmv,

ToL for Land is 507.9oR

Ruo is 360 w/m2

Eff is = 0.55

ΔRadCO2 = 5.35 × ln (C / C0)

In 2002, C is 373 ppmv,

∴ ΔRadCO2 = 5.35 × ln (C / C0) = 5.35 × ln (373/ 291) = 1.33 w/m2

Then the increase in temperature from the increase in CO2, alone.

ΔTLCO2 = TLo × [(1 + Eff × ΔRadCO2 / RULo)1/4– 1]

ΔTLCO2 = 507.9 × [(1 + .55 × 1.3 / 360)1/4– 1] = 0.14oF

The Water Vapor Feedback Effect is:

ΔWVCO2= 0.56 × 1.6 × Δ TLCO = 0.56 × 1.6 ×0.36 = 0.22 w/m2

The increase in total heating from this increase in the concentration of CO2, ΔRadCO2 + ΔWVCO2 = 1.33 w/m2 + 0.22 w/m= 1.6  w/m is consistent with the IPCC estimates of total increase in heating from all man made sources between 1750 and 2007.)

Then the temperature increase on Land with Eff = 0.55, resulting from the buildup of CO2 between 1880 and 2002, including the Water Vapor Feedback Effect, is:

ΔTL = TLo × [(1 + Eff × (ΔWVCO2 + ΔRadCO2) / RULo)1/4– 1]

ΔTL = 507.9 × [(1 + 0.55 × (0.32 + 1.32) / 360)1/4– 1] = 0.3 oF

Compare this Maximum increase in the Average Global Land Temperature effected by the buildup in CO2, 0.3 oF, to the actual increase in Average Global Land Temperature of 2.6 oF.

Using the ratio of Average Temperature to Land Temperature, 0.56, the increase in Average Global Temperature effected by the buildup in CO2 over this period is 0.2oF compared to the actual increase in Average Global Temperature over this period of 1.4oF.[8]

Clearly the buildup of CO2 over this period, 1880 – 2002, is not the cause of this temperature increase.[9]

The IPCC Formulations for Determining the Temperature Increase from the Buildup of CO2 are Incorrect and Substantially Overstate the Resulting Temperature Increase

The IPCC uses different formulae for calculating the increase in average global temperature from a buildup of CO2, which appear to be based upon the formulation of Arrhenius (1896) who set out his formula for a change in Average Global Temperature in degrees Celsius, as

ΔTArr = S × log2 (C/Co)

S, is the doubling sensitivity and it is normally given in degrees Celsius.

In Arrhenius’ paper, S can be determined as equaling 5.8o C. However, in his subsequent book, he suggests a smaller climate sensitivity, S = 4. Arrhenius & Borns (1906)

The IPCC’s most recent report (2013) states: “equilibrium climate sensitivity (the doubling sensitivity) is likely in the range 1.5 K [S] to 4.5 K [S] (high confidence).” IPCC (2013)

Since the IPCC is focused on the effects of doubling the concentration of CO2 from 400 ppmv to 800 ppmv, I will focus on this as well.

Such a doubling would result in an increase of 3.7 w/m2 in total heating power from the buildup of CO2, after applying the applying the IPCC formula for increases in heating of, ΔRadCO2 = 5.35 × ln (C / C0), increasing this for the Water Vapor Feedback Effect and with Eff = 0.55, this would give rise to an increase in Average Global Land Temperature, using the above formulas, of 0.8oF.

Referring to Figure 1, above, a 0.8 degree increase in Average Global Land Temperature corresponds to ~ a 0.4 degree, increase in Average Global Temperature.

Set out below in Table 2, below, is a comparison of the temperature results based on using the Arrhenius formulation for such a doubling, for values of S ranging from 1.5 to 4.5 and comparing the required increase in heating to effect such a change to the 4.3 w/m2 determined as set out above.

Table 2

Temperature and power required using Arrhenius Formulation for various values of S Proposed by the IPCC

S oC ΔTArr  

Deg. F

% Increase over actual temperature increase of 0.4oF % Increase in Power required to effect this temperature increase compared to actual power increase of 4.3 w/m2
1.5 2.7 488% 274%
2.0 3.6 684% 386%
2.5 4.5 880% 499%
3.0 5.4 1076% 613%
3.5 6.3 1272% 728%
4.0 7.2 1468% 844%
4.5 8.1 1664% 961%

The IPCC formulation for determining an increase in heating, ΔRadCO2, is dependent solely on the change in concentration, ΔRadCO2  is proportional to ln (C / C0). There is no “S” variable in this formulation. Therefore, the increase in heating is 3.7 w/m2, regardless of the value of S.

An increase in heating of 4.3 w/m2 can cause a 0.8oF increase in Average Global Temperature – no more; much less a range of temperature increases as high as 8.1oF.

To publish a range of the Maximum increases in temperature for the same increase in concentration and, therefore, the same heating is nothing short of scientifically absurd. If the Maximum temperature increase that the rate of heating can cause, is 0.8oF, that is it. This is best illustrated by column 4 which sets out the percentage increase in heating power required to cause the corresponding increase in temperature.

While some propose far greater increase in power from the Water Feedback Effect based on some theoretical concepts, the fact is the Water Feedback Effect has been measured. Any theoretical calculation or computer model that predicts a greater heating from this effect is wrong.[10]

Moreover, the basic and fundamental law that energy is always conserved, stands as a complete and total bar to any increase in temperature greater than 0.8oF.

Further, that the Arrhenius formulation, ΔTArr = S × log2 (C/Co) is simply wrong can be shown as follows:

Converting this expression to natural log function, then

ΔTArr = S × 1.44 × ln (C/Co)

As noted above, according to the IPCC, the increase in radiative power per square meter, ΔRadCO2, from an increase in the concentration of CO2, can be determined as:

ΔRadCO2 = 5.35 × ln (C/Co)

Thus,

ln (C/Co) = ΔRadCO2 / 5.35

Substituting ΔRadCO2 / 5.35 for ln (C/Co) in the Arrhenius formulation for calculation for change of temperature results in,

ΔTArr = 1.8 × S × 1.44 × ln (C/Co) = S × 1.44 × ΔRadCO2 / 5.35

which means that ΔTArr is directly proportional to changes heating, ΔRadCO2.

As noted above, based upon the basic principles of radiative heating,

ΔTCO2 = To × [(1 + ΔRadCO2 / RUo)1/4– 1]

which means that instead of being directly proportional to changes heating, ΔRadCO2, as Arrhenius assumes, ΔTCO2 is proportional to the fourth root of changes in heating, ΔRadCO21/4. Arrhenius’ conjecture is clearly not founded on the principles of physics.

The Arrhenius formulation and IPCC approach cannot possibly be correct.

Another writer, Ellis (2013) derives the equation for the increase in temperature, ΔTEll, in degrees Fahrenheit, resulting from an increase in heating, ΔRadCO2, which can be expressed as:

ΔTEll = 1.8 × 0.31× ΔRadCO2 = 0.56 × ΔRadCO2

Comparing this to Arrhenius, effectively in Ellis’ formulation, S is ~ 2.

These and similar calculations, Jacob (1999: § 7.4.3), in which the change in temperature is also directly proportional to changes in ΔRadCO2, instead of being proportional to the fourth root of the change in ΔRadCO2 as (1+ΔRadCO2 / Ru).25, do not comply with the radiative heating laws of thermodynamics and are simply wrong.

Given how straightforward the correct formulation is, one wonders why this is not employed by the IPCC and why “The IPCC’s range of uncertainty in the value of k[S] extends from 1.5 C to 4.5 C, with a central value of 3.0 C.”

Conclusion

The IPCC’s determinations overstate, significantly, the role of CO2 in Global Warming and are wrong.

The change in the Average Global Temperature for Land between 1880 and 2002 was 2.6oF. To effect such an increase requires an increase of 13.8 w/m2 in Total Average Heating Power. The Maximum total increase in total Average Heating Power that the buildup of COover this period could have effected is 1.6 w/m2. The Maximum increase in the Average Global Temperature for Land that the buildup of COover this period could drive cannot exceed 0.3 oF. Comparing 1) the Maximum increase in heating power of 1.6 w/mto the required increase in power to effect a temperature change of  Land of 2.6oF, 13.8 w/m2,2) the Maximum increase in temperature that can be effected by this increased heating of 1.6 w/m2, 0.3oF in the Average Global Temperature of Land, resulting from the actual increase in the concentration of CO2 between 1880 and 2002, to the actual temperature change of Land of 2.6oF and 3) comparing the correct prediction for a doubling of the concentration of CO2 of a Maximum increase of 0.8oF increase in Average Global Temperature compared to the IPCC’s range of 2.7 to 8.1oF, demonstrates, conclusively, that the IPCC is wrong. As a factor in Global Warming, increases in the atmospheric concentration of CO2 have been, and will continue to be, largely irrelevant.

This is not merely a scientific debate.

Governments across the globe are in the process of implementing and planning to implement, laws regulations, changes in taxing and offering direct and indirect subsidies and credits that in the future could result in costs that, in the aggregate, could equal the Annual Gross Domestic Product of the economies of all the countries in the World, based upon the determinations of and pronouncements from the IPCC. While potentially devastating to the economies and peoples of all nations, these efforts may not result in any meaningful reduction in the buildup of CO2, but even if they succeed in achieving this goal, this almost certainly will not result in a reduction of the Average Global Temperatures, because as a factor in Global Warming, the buildup of CO2 is largely irrelevant.

There will be no return on these economically damaging and tremendously costly investments.

Let me conclude with a few questions:

With all of the data possessed by the IPCC and all of the experts it has mustered, why is it that I have not seen any publications in which the IPCC, and its affiliates have:

1. Shown or discussed the increase in total heating power required to have caused the 2.6oF global average increase in land temperature since 1880?

2. Applied the computer models it uses for predictions to the period 1880 to today and compared the results to the actual average annual global temperature trends from 1880 to today?

3. Used the straightforward formulation, based on classical physics, to calculate the Maximum temperature increase a buildup in Carbon Dioxide can cause or explained why they view this as inapplicable?

Surely, the IPCC has considered these questions. If not, it should.

Looking back, it is now clear. The 2007 the Nobel Peace Prize was awarde because the work of the recipients would not qualify for an award of the Nobel Prize for Physics or Economics.

[1] Imagine a football stadium filled with 10,000 people (representing the atmosphere), with 100 to 400 people close to the field hollering all of the time (representing the initial level of GHG). The noise increase at field level from the addition of one more hollering person assigned to the highest seating level is similar in effect to the heating increase of one part per ten thousand of CO2.

[2] “…general circulation models (GCMs) can be used to estimate the surface warming associated with an increase in Greenhouse Gas concentrations. The GCMs are 3-dimensional meteorological models that attempt to capture the ensemble of radiative, dynamical, and hydrological factors controlling the Earth’s climate through the solution of fundamental equations describing the physics of the system. In these models, a radiative perturbation associated with increase in a Greenhouse Gas (radiative forcing) triggers an initial warming; complex responses follow…… There is still considerable doubt regarding the ability of GCMs to simulate perturbations to climate, and indeed different GCMs show large disagreements in the predicted surface warmings resulting from a given increase in Greenhouse Gases. …. Despite these problems, all GCMs tend to show a linear relationship between the initial radiative forcing and the ultimate perturbation to the surface temperature, the difference between models lying in the slope of that relationship.” (Jacob §7.4) (Emphasis added)

As noted below, the relationship between temperature and radiative heating is that temperature increases as heating to the ¼ power. (∆T µ ∆F1/4). It is not linear, which would greatly overstate the increase in temperature by hundreds of a percent. A “linear relationship between the initial radiative forcing and the ultimate perturbation to the surface temperature” is contrary to correct “fundamental equations describing the physics of the system”. Basic thermodynamics also teaches that the rate of heat transfer to the Earth’s surface cannot exceed the sum of the net radiative heating from current solar and back radiation.

[3] The MODTRAN algorithm solves the Line By Line radiative transfer equations at very fine spectral resolution.

[4] This equation is based on a determination for the optical (IR) opacity of CO2 and the assumption that the most significant and variable GHG, Water Vapor, was constant. This is not a valid assumption. More importantly this calculation ignores the very real and complex effects of CO2 band saturation, which can only be determined accurately using a very sophisticated computer model. Based on the simulations I have performed; the IPCC model produces results that are consistently higher than the output of the Modtran computer calculations.

[5] Knowing that Land covers 29.4% of the Earth’s surface, the Oceans account for 84% of total evaporation (Cox), in 1880 the average Land temperature was 2.6oF lower, using the energy budget data from Trenberth (2011), measured changes in solar heating and the Water Vapor Feedback Effect for changes in temperature, with –

1. Up Radiation adjusted for relative changes in Average Global Land Temperature to the fourth power,

2. Back Radiation adjusted to take these changes in Up Radiation into account after accounting for the Water Vapor Feedback Effects, and

3. Thermal Convection calculated as Total Heating less Up Radiation and Evaporative Power Land for the respective year.

one can estimate the Earth’s average energy budget.

[6] “From 2002 to 2009, an infrared sounder aboard NASA’s Aqua satellite measured the atmospheric concentration of Water Vapor. Combined with a radiative transfer model, Gordon et al. used these observations to determine the strength of the Water Vapor Feedback. According to their calculations, atmospheric Water Vapor amplifies warming by 2.2 plus or minus 0.4 watts per square meter per degree Celsius. This value, however, is only the “short-term” feedback—the strength of the feedback as measured during the observational period. This value is subject to short-term climate variability. The true value of the feedback, the “long-term” value, is what the short-term observed values should trend towards when given enough time.”

Using a series of climate models, the authors estimate the strength of the long-term Water Vapor Feedback. Extrapolating from their short-term observations they calculate a long-term feedback strength of 1.9 to 2.8 watts per square meter per degree Celsius.” 2.8 watts per square meter is the Water Vapor Feedback measure employed in this paper for temperature measured in degrees Celsius which is converted to 1.6 for temperature measured in degrees Fahrenheit.

While this measurement relates this amplification in heating to linear changes in Average Global Temperature, not to changes in temperature to the fourth power, this is likely so because this is a measure of changes in concentration which, over time, are driven by evaporation which changes linearly with temperature, the effects of which are orders of magnitude greater than changes in heat flux from changes in temperature.

[7] Of course, temperatures vary across the globe. If one performs this calculation for a range of initial temperature changes, ± 30oF, for example, and adjusts the Up Radiation accordingly, the average temperature change of this range is within one percent of the average temperature change calculated using this formula. Therefore, the Average Global Land temperature increase is calculated as set forth above.

[8] Referring to Figure 1, it is evident that Global Warming did not commence until the late 1970’s and ceased prior to 2002.

If one does the same calculations for the 38 ppmv increase in CO2 over this period; the Maximum increase in the Average Global Land Temperature effected by this buildup in CO2 is 0.2 oF. The actual increase in Average Global Land Temperature over this period is 1.8 oF.

The increase in Average Global Temperature effected by the buildup in CO2 over this period is 0.1oF compared to the actual increase in Average Global Temperature over this period of 1oF, or 10% of the actual increase.

[9] Global Warming nonetheless occurred between the late 1970’s and 2002. I show in another paper what the likely causes of this were.

[10] There are those who believe a range is appropriate due to the inability to precisely predict the impact of delays in reaching an equilibrium temperature and the difficulties associated with modeling the thermal diffusivity and responses of the Oceans and the manner in which the atmosphere responds to increases in heating.

Given an increase of 1 -2 ppmv per year in the concentration of CO2, reaching an equilibrium temperature on Land should occur far faster than the rate of change. But, whether or not this is correct, this paper assumes that the equilibrium temperature, which is the Maximum temperature, is reached and while all of these oceanic and atmospheric factors make it difficult to predict the precise effects of increases in GHG heating, these ranges must all be less than the Maximum increase in the Average Global Temperature that the heating can effect. They cannot exceed the Maximum number.

The premises AGW theory was based on are all wrong . I do not know what more is needed.
No tropospheric hot spot.
No evolving +AO
No decrease in OLR
The pillars this theory is based on all not materializing.
The temperatures increase last century was all due to the terrestrial items which govern the climate pushing the climate into a warm mode.
As I have said now with low solar conditions post 2005 the terrestrial items are going to push the climate into a colder mode.

Thanks Trebla

Stefan-Boltzmann constant, 5.40×10-9 w/m2 T-4 and TL is the Global Average Land temperature in degrees Rankine.

Note the temperature units are in antediluvian “degrees Rankine.”, not kelvin, though he should not use T as a unit.
the rough scaling of Fahrenheit to celcius is 9/5 , (9/5)^4 =10.5 , so the value given is probably correct though I have not been able to find a reference using his units. Most people using Rankine for temperature probably passed away before the end of the last millennium.
This comes from the the days of ergs, slugs and Btu.
σ = 1.73 x 10~9 Btu/ft2/h/Rankine4
I would suggest the author uses units which everyone can follow and condenses the text to a quarter of the size in the hope that someone may get to the end.

That’s because of the author’s bizarre choice of a mixed set of units!
He’s using W/m^2.ºR^4 as opposed to the usual W/m^2.K^4 consequently his value for the S-B constant differs by a factor of (ºR/K)^4 i.e. (0.095), hence his 5.4×10^-9.

This whole essay would be wrong if there was a tropospheric hot spot. The IPCC intellectual edifice was built around the amplification from water vapour.
Without that the limits that this essay describe come back into play. And thus, yes, the IPCC was wrong.

Given how straightforward the correct formulation is, one wonders why this is not employed by the IPCC and why “The IPCC’s range of uncertainty in the value of k[S] extends from 1.5 C to 4.5 C, with a central value of 3.0 C.”

If the formulation is that simple why does it half an hour to read his explanation. I got bored after about five pages?
When people who claim to have technical backgrounds don’t know the correct symbol for the unit of power is W and get the SB constant wrong, I soon lose motivation in digging through the rest.
BTW , if he was paying attention, the IPCC explicitly refused to give a “central value” in AR5 and the author has simply taken the mean of the two end values ( not the median of a the distribution of values ) and falsely attributed this to the IPCC.

7. One cannot determine the increase in Average Global Temperature based upon a change in heating because the surface temperature change response of Land and the Oceans to an increase in heating is significantly different.

Full marks for that observation. Something the IPCC has been brushing under the carpet since the beginning.
As we can see by looking at rate of change of temperature on land and sea; land needs to be scaled down by a factor or two.comment image

I’m with ya greg. The whole IPCC and this set of equations assumes a constant average albedo. Incoming radiation all gets absorbed by the system, and the earth or oceans.
But that’s rubbish. It gets reflected by clouds, it never arrives. Clouds are modulated by water vapour, at least. i.e. more water vapour leads to more clouds. There is as big a case for saying water vapour feedback is NEGATIVE, as positive.
Ergo the whole thing is far more complex than either the IPCC OR this post suggest.

TH, the IPCC models cannot be right. Simulating important physical processes like convection cells ( tstorms) require physical grids on order of 1.5-4km. Computational constrainst mean the finest grid in CMIP5 is 110 km at the equator. UCAR says doubling resolution by halfing grid sides increases computation 10x. The computational constraint is 6-7 orders of magnitude, not solvable for decades if ever. So such essential processes must be parameterized. Those parameters must be tuned to hindcast realistically; for CMIP5 expressly YE2005 back to 1975. This introduces the attribution problem highlighted in my comment to Any May’s guest post. For more details on this brief models comment, see my guest post here (last year?) on Models.

models are tuned to do a best fit to the late 20th c. warming. Usually 1960-1990 and fail to match the equally strong early 20th c. warming. They are therefore necessarily wrong and mis-attributing the multiple causes of change.

somewhat off topic but, I’ve taken an interest in computing global averages for the Tmin and Tmax values, and have downloaded HadGHCND from ftp://ftp.ncdc.noaa.gov/pub/data/ghcn/daily/grid and noted they defined the data grids as “grid spacing = 3.75 deg x 2.5 deg”, which would mean for every latitude the actual surface area of the grids change. Anything I would consider a Global average would have to weight the grids for varying surface area, does anyone know if this has been done for the global average temps published?

I have a problem with:
6. The Maximum average increase in Land temperature in degrees Fahrenheit, ΔTL resulting from of the calculations set out in statements 4 & 5 of ΔRadCO2 and ΔWV is determined by this formula as
ΔTL = TLo × [(1 + Eff × (ΔWV + ΔF) / NHLo)1/4– 1]

I would think that the temperatures ΔTL and TLo should be on the same scale, in which case the arbitrary zero-point of the Fahrenheit scale becomes a problem for TLo.

William,
“Due to the percentage that goes into subsurface heating as a result of the thermal diffusivity of the Oceans, the surface temperature of the Oceans is not as responsive to the same radiant heating as Land.”
Also, the heat capacity of water is 4X most solid surficial materials, so one would expect that the surface is going to heat about 4X faster than water, even ignoring the cooling effect of evaporation at the ocean surface.

Greg
Reply to  Clyde Spencer
December 11, 2016 10:39 pm

Land is better approximated as ‘moist rock’ that solid rock. The specific heat capacity seems empirically to be about half that of water. This is a key point though.

Greg,
Heat capacity will vary from about 1/4 that of water for dry sand and bare rock such as one finds in glaciated terrain, or relatively recent lava flows, to the equivalent of ocean water for open bodies of fresh water. I don’t know what the average value is, but the USGS has developed landuse classification maps from which one could derive a mean value for at least the US. 2X seems like a reasonably good starting point (with one significant figure), but like so many things related to climate, such as reflectance, these may not be constants and vary with the seasons and weather. When one starts looking at the details of the problem, the complexity is so great that it staggers the imagination that anyone would call the science “settled.”

Just…,
Fig. 1 isn’t really a lot of help in adding more precision to the ratio. In recent years, the land high-temperature anomalies have been about 2X the ocean high temperature anomalies. However, about 1885, the land low-temperatures have been at least 4X the ocean lows. Also, the same is true for the ’50s through ’70’s. So, the relationship of land to ocean temperature anomalies doesn’t appear to be symmetrical. As usual, the relationships are anything but simple. The important take away is that land-temperature responses are at least 2X more sensitive to changes than the oceans.

Given that alarms in submarines don’t go off until CO2 is at 8,000 (yes that’s “eight THOUSAND) parts per million, I would venture to say that we have some wiggle room there.
Compare this with cyanide, which kills at 100 to 200 (that’s HUNDRED) parts per million in air (if I read correctly).
… NOT that breathing CO2 is so much the issue in the global-warming debate, but assuming we could stand a tad more heat, it certainly seems to be NOT so bad in larger concentrations, in other respects.

Just for you, I’ll lay it out slowly:

2) Diderot [not being a mathematician] did not know how to respond
3) From Euler’s view Diderot was one of the ‘unwashed masses’ who you can impress with meaningless math https://en.wiktionary.org/wiki/unwashed_masses
4) I started to try to figure out what the salient points were and was stumped [on several equations] and expressed my frustration with the unclear and confusing post which did seem to impress several people
5) Since you profess to ‘get it’ you can be helpful [instead of just whining] and help me [and many readers] out by explaining the math [and more importantly the ‘physics’ behind it]
6) Start with the first equation ΔF = [(TLo + ΔTL) / TLo)^4 – 1] × RULo / Eff
This way, you can make a useful contribution.

Wash yourself in mathematics as you will, it is just logic written in Sanskrit. I agree that some of the Sanskrit above makes poor bathwater, and wish to add a criticism of the use of emissivity. “ε is emissivity, a dimensionless constant between 0 and 1 that determines the efficiency of a body to radiate and absorb energy”.
While this is generally true, Carbon dioxide and Kirchhoff do not appear to get along.
It appears that a material property of CO2 is extremely high absorptivity, but about .002 emissivity according to Monsieur Hottel and others. An unwashed bloke might say CO2 prefers to absorb and dance rather than absorb and spit.
Absorptivity is not commonly given a factor, but it is well known that the WN 667.4 fundamental bend is 98% absorbed in one meter at standard atmosphere and 400ppm.

The premise for this article is that if there is a causal relationship between more CO2 and temperature the maximum amount that could occur has been overstated dramatically by the IPCC. I am a layman both scientifically and mathematically. It has always seemed to me that even this basic premise is wrong and potentially the only correlation I believe is possible is that increased global temperature may lead to increases in CO2. I think that if man’s contribution to atmospheric CO 2 didn’t exist the temperatures would be the same. The only way that man influences the global temperature both past and future is how man manipulates the data and the models to suit the narrative. Ironically I think that the global warming narrative could’ve evolved on some other random gas or bi product of human growth output but was chosen because it was not easy to disprove ( except over time, which I believe has occurred ). To me this is not much different for blaming CFCs for the hole in the ozone layer. I have no idea whether it made any difference or whether even the ozone hole existed and was caused ( or impacted on ) by humans. All I do know is that as a specie man is manipulateable and gullible due to the emotions of guilt and empathy and these emotions can be exploited to make man to willingly part with huge amounts of money to those who are the exploiters. But the AGW movement ultimately has pushed things too far and the goose that has laid the golden eggs is about to meet its maker ( we hope). With so many vested interests aboard the global warming / climate change freight train it has been difficult to stop ( or even slow down) but hopefully the Trump era will cause the necessary derailment to finally bring this shameful era in mans history to a close.

DS, your observation about deltaT=> delta CO2 is correct on long time scales, verified by ice cores and explaind by Henry’s law. Gore was wrong. But that does not speak to shorter time intervals given that CO2 is for sure a GHG. But that lab truth does not speak directly to AGW, because of known feedbacks like water vapor and clouds. Best present observational estimates are ECS~ 1.65, about half of modeled ECS. In which case there is no C in CAGW, and only a little gw.

synonyms: patronize, talk down to, look down one’s nose at, look down on, put down
“don’t condescend to your readers”
do something in a haughty way, as though it is below one’s dignity or level of importance.
“we’ll be waiting for twenty minutes before she condescends to appear”
synonyms: deign, stoop, descend, lower oneself, demean oneself;
Also, I don’t consider ‘unwashed masses’ to be an endearing term in customary use…not in my experience anyway.

I am not in control of what you think my comment ‘implies’, and you are not stupid, but perhaps stubborn and self-righteous. I started out by stating that I had a problem with the post. This refers to me and my problem, not to whether the post had a problem, so it should be clear that I was one of the unwashed. And, indeed my problem was resolved when it turned out that the problem was the non-obvious use of the Rankine scale. For the rest, I will note that the derivation of many of the fundamental equations is not clear [to me and to most]. But nobody [including the genius who ‘got it’] has been forthcoming with the derivation, so at this point we are still unwashed.

THE GOOD
Calcs done at surface. One of my pet peeves, which I have voiced for over a decade, is that the IPCC appears to have done all their sensitivity calculations at the Effective Black Body temperature of Earth. That’s -18C, which occurs about 14km up from the surface, where neither we (specifically) nor the biosphere (generally) give a fig. The same calcs done using surface temps of +15C yield a sensitivity about 2/3 of what the IPCC quotes. So they’re not wrong per se, just engaged in some clever misdirection.
THE BAD
Trying to follow math that wanders between units (Fahrenheit, C, K, and oh my goodness, Rankine) is a challenge for everyone. Do it all in deg K. It would be a lot easier to follow your math, and you eliminate the possibility that you are fooling yourself by conflating units in the same equation (same observation as Leif above).
THE QUIBBLE
I don’t think you can treat water vapour feedback the way you have. Water vapour varies by altitude, latitude, season and so on. So CO2’s warming effects are rather different at surface (due to prevalence of water vapour) versus at say 10 km altitude (due to absence of water vapour to compete with CO2 in the absorption of IR).

Germinio
Reply to  davidmhoffer
December 11, 2016 6:40 pm

Actually David, one of the worse parts of the post is the fact that the calculations are done at the surface
rather than at the “mythical” surface of last emission. It has to be done there else the energy balance equations do not hold. It is only at the surface of last emission that the solar energy in = thermal energy out.
And a simple calculation shows (as you know) this occurs at a temperature of about -18C.
Personally I do not have the time or inclination to go through this post to see if it is valid or not. But I
would strongly suggest that it is highly likely to be wrong. At the end of the day I do not think that any
flaws in the greenhouse gas theory are sufficiently large that that they can be demonstrated using high
school maths and result in a answer that is off by a factor of 4 or 5. Unless you believe that there is a
real conspiracy to lie about the effects of CO2 then you should at least think that any errors in the theory
are a lot more subtle than what is claimed here. As a first check I would ask if this new theory can correctly
predict the current average temperature of the earth. If it cann’t then it certainly cannot predict what effects
doubling CO2 will have.

I wish he would simply linearise. To fuss around with fourth (and 1/4) powers in dealing with averages like
“ΔNHL = RULo × [(TLo + ΔTL) / TLo)4 – 1]
Where ΔTL is the change in the average surface temperature of Land, and”

when T_L has already been linearly averaged, is pointless. S-B does not apply to averages. Just write
ΔNHL = RULo × 4 × ΔTL / TLo

December 11, 2016 12:43 pm

While I agree the IPCC is wrong, I disagree that this is so for the reasons given in this guest post.
First. A number of the greenhouse ‘physics’ observations used to derive the post’s math model are simply incorrect misunderstandings. Therefore the math model cannot be correct. The only source of surface heating (both land and ocean) is incoming solar SWR not reflected by albedo. This is only at the surface since the atmosphere is obviously transparent to SWR. Not Surface heating =SWR plus IR backradiation. That is a too often repeated skeptical misconception. The GHE is occaisioned by diminution (via ‘scattering’ delay) of outbound IR cooling. The GHE is NOT a direct heating effect; it is a reduction of radiative cooling effect which therefore results in net warming. Outbound radiative cooling IR starts at the energetic IR wavelength of the generating surface temperature. Any IR absorbed then re-emitted by GHG (‘scattered’) in the atmosphere will be at a lower energy level due to the troposphere’s temperature lapse rate. IR escaping to space where it can be measured by satellites above TOA is energetically at the temperature of the effective radiating level (ERL); that temperature is used to infer the ERL altitude from the temperature lapse rate. CO2 saturation near the surface is not relevant to GHE. Only the ERL is, and more CO2 simply moves it higher so that the CO2 GHE effect NEVER saturates (another unfortunately all too ofter skeptical misconception); it is indeed ~5.35*ln(Csubt/Csub0).
Second, absent feedbacks a doubling of CO2 causes +1.1-1.2C (lindzen uses 1.2C, the third of Monckton’s recent error posts can be used to compute 1.16C). This can be calculated approximately from first principles and experimental values. The water vapor feedback is observationally positive. The post’s fourth Dessler 2014 Phys.org reference is wrong; it returns 404 error. But it is possible to find via google the March 2014 phys.org posting; it refers to an observational 2013 paper by Gordon et. al. discussed in footnote 6 of the post. Therefore the GHE of CO2 doubling MUST BE >1.2C (Lewis and Curry 2014 estimates 1.65C). Therefore it CANNOT be the 0.8F (0.44C) calculated by this guest post math model. Which is a separate way of showing the math model is wrong.
There are several ways to show IPCC incorrect: Discrepancy between model and observational ECS, attribution (see Andy May’s recent guest post and my main comment to it), no SLR acceleration, acceptance and use of the hockey stick in TAR, the Himalyan glacier goof in AR4, biased meta-analyses (essay No Bodies gives an AR4 WG2 example uncorrected in AR5), overstated certainty/confidence. This post is not one of them.

I think it refers to this paper by Dessler. But it makes no sense. Dessler gives wv feedback as 1.2 W/m2/K, But here it comes out as 1.6, said to be in F. But if so, the conversion is wrong.

I tracked the correct reference to Gordon 2013 down already. See main comment for details. One of the few things this oldish JD/MBA leatned to do well is verify fast using googlefu.

“The water vapor feedback is observationally positive.” I thought that that was in doubt. A few years ago, I looked at the weather balloon data for specific humidity where the hot spot should be, and found that it had a negative correlation with temperature. That suggests (to me at least) that some aspect of the water vapour feedback is negative.

wnkl, see the estensive (and Lindzen vetted) climate chapter discussion in Arts of Truth. Turns out the IPCC AR4 blackbox conclusion 8.1 is nothing more than meta analysis bias, including rejected conclusions, ignored conclusions, and over reliance on an obviously flawed single sat study since contradicted in spades.

“The water vapor feedback is observationally positive.”

What was measured was a slight increase in dew points, but a decrease in average rel humidity.

December 11, 2016 7:13 pm

Yes, precisely. Specific humidity determines WV GHE. So if relative is dropping, then specific is rising less than predicted by AR4 WG1 black box 8.1. So the WVF must be less than IPCC models assume. Telative humiditymis irrelevant to GHE, only specific humidity matters. See essay Humidity is still Wet if you are confused by the distinction. Absolute water vapor determines GHE, not how much is relatively present given some temperature and pressure.
That is still not a negative ‘first derivative’ feedback. It is only a less positive first derivative feedback. That suffices for all ECS calculations from whatever source. See other comments this thread for explicit clarification.

Possibly the effect, but it is definitely rel humidity that determines it’s lack of affect on cooling at night under clear skies.

When I looked (using data downloaded from NOAA) both specific and relative humidity fell with increased temps. Specific humidity was not rising less than expected. It was actually falling.

ristvan – I have no criticism of the main thrust of your argument, but I question the logic by which you arrive at “the GHE of CO2 doubling MUST BE >1.2C“. If cloud feedback is negative, as seems extremely likely, then the GHE effect of CO2 doubling could in fact be <1.2C. [As an aside: Water vapour feedback may be much less than thought, if the water cycle has not been properly taken into account, but it still seems very likely to be positive.]

MJ, you have a completely valid detail point. Very good for following my arguments astutely. Bravo.
BUT, all the albedo, cloud observation (ICOADS, ISCCP) and related results (precipitation) say cloud feedback is ~0. See essay Cloudy Clouds for AR5 details. The observational ECS given all non water non cloud feedbacks netting to about zero suggests wv is positive and cloud is about zero,or slightly negative. The 2010 2 Dessler paper is embarassingly bad, but actually suggests ~0. My own opinion is that cloud feedback is slightly negative, based on Lindzen’s adaptive iris hypothesis. But given positive WV uncertainty, in the net net, dunno. Can construct many math scenarios computing observational ECS~ 1.65. But none corr sponding to observations without some positive WVF and near zero CFB.

Dear Ristvan
Thanks for this particular post as it corrects an understanding I had picked up that backward
IR from CO2 and WV added heat to the atmosphere
I recall arguments along the lines that the IPCC had conceded that the warming from IR back radiation from CO2 was around 3 WM2
The implication being that this was very small
cf the incoming solar SW radiation at 1368 WM2 at TOA
If I have understood you properly you seem to
say there is no back radiation heating effect but the absorption of OLR by CO2 slows down the rate of OLR leaving the surface and the atmosphere meaning a warmer atmosphere than might otherwise have been- hence some global warming
Two questions
1 In light of the above is the IPCC estimate of 3WM2 from CO2? still valid or applicable or even relevant?
2 In your 11th line should that read Net Surface Heating (instead of Not ) ?

Clyde Spencer

December 12, 2016 2:01 pm

ristvan,
You said, “The ONLY source of surface heating (both land and ocean) is incoming solar SWR not reflected by albedo.”
That is not correct. ALL incoming radiation that is absorbed results in heating, with the exception of the red and blue light that drives photosynthesis. (and that is primarily a time-delay loop) Whereas, the back radiation is composed of reflected (un-absorbed) SWR radiation and emitted IR. (Actually, there is also a fluorescent red line from chlorophyll that is probably stimulated by UV and possibly blue light.) However, it is only the outgoing IR that is susceptible to absorption by CO2 and uncondensed water vapor.
Also, your use of the term “albedo” is unconventional. Strictly speaking, albedo is a measure of the property of things like clouds and plants to be able to reflect a fraction of the light impinging on them; albedo is that fraction. That is, albedo is a unitless ratio of measurements, and has no capacity to reflect light in and of itself.

The problem is what to do about it. How do you convince the media to do some checking, how do you convince the media to print more logical conclusions.
But most of all is how do you get the politicians to actually consider some real facts instead of “warming LINKED to increase in CO2”, and “97 % percent of scientists agree”?

I am a skeptic, especially of the proposal that CO2 can have, let alone, does have any effect on global temperature. I am a research scientist, retired, who has been disgusted with the ‘97% òf climate scientists.`
I have lost friends over my refusal to `fit in` and accept the consensus. I took early retirement after my director told me to just accept the newly announced (KYOTO) dogma as it would mean more $$$ for research – good research. He implied that scientific truth would prevail. How wrong he was.
Over the years I have learned to become even more of a skeptic. Through the application of retroduction CO2 cannot have any effect on temperature. CO2 does not generate energy and thus cannot heat its environment. It is but a molecule of the atmosphere, and like all molecules it receives its energy from its environment. Regardless of the composition of the atmosphere, global warming can only result if energy in exceeds energy out. Conversely, global cooling results if energy out exceeds energy in. This is made apparent by examining the earth’s TOA energy balance.
So why do so many claim that CO2 is unique and, moreover, results in a runaway temperature effect? Logic would preclude such a belief.

It has been discussed many times on this site, and I think it is right, that the feedback from water vapour is negative. That is, any additional heating by extra CO2 causes more evaporation, which blocks the sun & reduces the energy input.

Latitude, I am trying here to educate dedicated skeptics so that their arguments are immune to warmunist counters. Please consider this a friendly helpful comment; Leif was right and you weren’t upthread. Not a nice exchange.
You perhaps misunderstand (but certainly misstate) the notion of climate feedbacks to delta CO2. Conceptually, these are ‘first deirvatives’, a change in a GHE with respect to a change in CO2. At constant CO2 (say 280ppm) the primary effect of water vapor as a GHG is to keep Earth’s average temperature about plus 15C rather than minus 18C. That fact is whynwe are alive to have this conversation. You can google the reasoning. No thermal runaway, and ~thermal equilibrium SWR = OLR.
The CAGW feedback question is, what does an an increase in CO2 do to change that primary water vapor GHE. All the evidence points to a weak positive effect (a bit stronger warming than from CO2 alone, see comments upthread to others in the same hopefully helpful vein), expressed in Bode f terms as f~ 0.25-0.3. If cloud feedback is zero or weakly negative (the available evidence indicates this is so, and all other feedbacks net to about zero per IPCC) this translates to ECS ~1.65-1.7, which foots nicely to the observational energy budget models starting with Otto 2013. My preferred observational ECS paper is Lewis and Curry 2014. For many interesting details and footnotes accessible to laymen, see essay Sensitive Uncertainty in my ebook Blowing Smoke.

Some (or most) warmists accepted the “theory” that increasing CO2 has a positive feedback of water vapor which then increases the warming. However, this has never been proven or measured. It might still be in the equations of the models which is one reason they are always over calculating the warming.

No. Individual feedbacks can be positive or negative. The net sum will always be dominated the T^4 Planck f/b which is negative and why the system is long time stable. Clearly overall f/b is negative since we are here.
Much confusing has and continues to be caused the IPCC talking about net feedbacks possibly being positive or negative because they are NOT COUNTING Planck when saying that. Sadly Monckton has gone along with this ridiculous and misleading way of talking about feedbacks.
This misleading suggestion that net f/b may be positive leads to talk of tipping points in and run-away global warming which are the cause of much concern and hysteria.

The easiest way I have of understanding the ‘right buggers muddle’ that is climate models a la IPCC, is to see that the IPCC position relies on three basic assumptions.
(i) That the physics of IR absorption and re-emission of CO2 is correct. It probably is.
(ii) That nothing else is driving climate change, ergo it its getting warmer faster, than (i) suggests, there is POSITIVE FEEDBACK, not some other driver as well. This is almost certainly a wrong assumption.
(iii) That water plays a huge part in feedback. This is almost certainly true. Negative feedback however. Not positive.
There are a couple of other assumptions as well, based in the fact that non linear partial differential equations can be accurately modelled by assuming they are linear, and adding in fudge factors (parametrisation) over broad ranges of variation. That sometimes works for small non linearities.
To my mind, the staggeringly convenient lie that is assumed to be true, by the alarmist community is (ii) .
This post asserts its truth (I think: the math obfuscates everything), but disputes its value…
At which point I kinda give up.

No, supposed means based on supposition, ie it is unproven, not that is wrong or disproven. Some people may sarcastically use “supposed” to imply something is wrong without bothering to disprove it in a falsifiable manner.
In “CO2 is supposed to raise temps a little” , supposed does not sarcastically imply “it ain’t”.
It may arguably be undetectable or insignificant but it would be hard to suggest ‘it ain’t” as in does not raise temperatures even a little. Even if there are very strong negative feedbacks, the new temperature would be marginally higher, otherwise there would be nothing to induce the feedback. That is how feedbacks work.

During the day, you would get the warming from whatever the increase in ir “fog” there is. But it is radiated if not that night, the next clear night, lowering morning temps right down to the dew point, and then a bit as some of the condensed water goes into the water table, before reevaporating the next day.

Within the scheme of things, the issue of whether additional atmospheric CO2 would produce X or Y temperature effect is irrelevant, since there will never exist those levels of atmospheric CO2, due to transformation of power generation to molten salt reactors and automotive vehicles to electric.
The issue of concern is a significant reduction of atmospheric CO2. We know for certain some of the effects of such an event and they would be catastrophic. Yet I hear nothing from the folks who want to completely eliminate CO2 emitting processes from our world. The biggest errors otherwise intelligent folks make are due to embracing a false asumption , like “The less CO2, the better.”

December 11, 2016 1:30 pm

The problem with calling CO2 a greenhouse gas on a water planet is that CO2 reacts with water to form bicarbonate, HCO3-. That is an acid, not a gas, and with that, the radiance effect is nullified. In contact with a world ocean, CO2 reacts with sea water rich in calcium to make carbonate, CaCO3, which is used by microorganisms or precipitated. High atmospheric CO2 makes calcite ooze in the ocean continental shelfs.

Reply to  Arfur Bryant
December 11, 2016 2:50 pm

AB, you have grasped the essence of the ‘misconceived physics’ problem with this post. Atmospheric CO2 doesn’t and from first principles cannot heat anything. The greenhouse gas effect retards radiative cooling by infrared radiation emitted by Earth’s surface heated to whatever temp by incoming solar radiation and watwr vapor as a transparent to solar GHG. The cooling retardation is because CO2 is a linear molecule that can absorb and re-emit (in any direction, ‘scattering’) IR wavelegths that correspond to Earth’s surface temperature. (Digression: It is not as potent a GHG as H2O becaue H2O is a ‘Mickey mouse eared’ polar molecule with more quantum vibrational IR photon absorption modes. That physics truth is your microwave oven.) CO2 and ‘backradiation’ cannot heat anything, only retard cooling. All heating comes from higher energy (shorter wavelength) incoming solar radiation. To repeat, AGW is not a physics warming problem. It is an impaired cooling problem when incoming solar ‘heating’ is roughly constant. See my longer comment upthread. For details with illustrations and references, see essay Sensitive Uncertainties, for which this basic stuff is just part one of a longer conceptual exploration of ECS.

Is it not the case that H2O, a bent molecule, also retards cooling but more powerfully because structure offers more quantum vibrational absorption modes = also not heating?

Thank you Rud for saying that I have grasped the essential misconception. It seems that the premise upon which this post is based is incorrect, therefore the rest becomes assumptive.
I do, however, have a slight doubt about the term ‘retarded cooling’. I understand what you mean but I would have thought ‘delayed cooling’ is a better term. And this delay is very short. As the backradiation from CO2 is at a lower frequency (and therefore unable to raise the internal energy of the surface), then as it interacts with the surface molecules it is either transmitted or re-emitted immediately at the same frequency (like reflected). On being re-emitted, as it is unlikely to interact with the same or another CO2 molecule in the atmosphere (there being only 0.04% CO2 molecules by volume in the atmosphere), that radiation (photon, if you like) will still escape to space. So any radiative ECS appears to be based upon the notion (postulation) that a doubling of CO2 (0.028% to 0.056%) is likely to cause warming due to the slightly delay of (approx) 33% of the backradiation from maximum 0.056% bv being delayed very slightly.
So where does Lindzen get his ECS of 1.2C? This seems rather high…
Thanks for you time but I won’t be able to respond any more tonight.

AB, time shifted additional info you can verify via google. The scattering ‘delay’ (your term) is currently measured by satellite above TOA as an about 0.6w/m^2 radiative imbalance subject to measurement, seasonal, and hemispheric uncertainty. It is both real and net significant. The IR ‘fog’ is very substantive. I do not have the chops to do the radiative frequency line by line quantum calcs, but Modtran and Hitran do. Take your pick as they basically both calculate the same conclusion.

Do you think they can take global measurements for a year, and narrow the uncertainty to detect a 0.6w/m^2?
I would be surprised if a single measurement had anywhere near that low an uncertainty to detect 6/10 of a watt imbalance.
And was the modtran a static snapshot of the dynamic night time cooling dynamics?

AB, you have grasped the essence of the ‘misconceived physics’ problem with this post. Atmospheric CO2 doesn’t and from first principles cannot heat anything.

Actually it does, there are two mechanisms: first in the lower troposphere the energy in the excited rovibronic state is predominantly transferred via collisions to neighboring molecules, those molecules have been heated and the excited CO2 is cooled. Second, if a photon is emitted (before collisional deactivation) then when it collides with say the earth’s surface, it transfers its energy to the absorbing surface, thereby heating it.
The cooling retardation is because CO2 is a linear molecule that can absorb and re-emit (in any direction, ‘scattering’) IR wavelegths that correspond to Earth’s surface temperature. (Digression: It is not as potent a GHG as H2O becaue H2O is a ‘Mickey mouse eared’ polar molecule with more quantum vibrational IR photon absorption modes.
The absorption of IR by CO2 in the 15 micron band occurs when the CO2 molecule is bent, when it is straight it has no dipole and so can’t absorb (because it is vibrating in the bending mode it spends the vast majority of its time ‘bent’)

[“The scattering ‘delay’ (your term) is currently measured by satellite above TOA as an about 0.6w/m^2 radiative imbalance subject to measurement, seasonal, and hemispheric uncertainty. It is both real and net significant.”]
I browsed the Stephens et al 2012 paper. It states the imbalance is 0.6+/-0.4W/m2 but the uncertainty is 4W/m2. How can this be significant when measuring TOA radiation levels approximating 240 W/m2?
Phil:
[“Second, if a photon is emitted (before collisional deactivation) then when it collides with say the earth’s surface, it transfers its energy to the absorbing surface, thereby heating it.”]
No, there is no energy gained by the surface molecule as it is at an already higher energy state than the incoming photon and therefore the photon is unable to bridge the energy gap required to elevate the surface molecule to a ‘warmer’ energy level. Backradiation cannot heat the surface directly, unless the surface is colder than the atmosphere (in which case the atmospheric molecule would not have been ‘warmed’ anyway…). Rud is correct here.

Arfur – “(Stephens 2012) states the imbalance is 0.6+/-0.4W/m2 but the uncertainty is 4W/m2.”
You are mixing instruments here, the 0.6 from surface thermometers (precise & accurate) the 4 from radiometers (only precise) in orbit. The 2012 paper states the EB imbalance of 0.6+/-0.4W/m2 is from “best estimate ocean heat content (OHC) observations” going on to state from Argo data. The uncertainty of 4W/m2 is from un-calibrated CERES data obtained by precise but not extremely accurate instruments. So CERES team calibrates their raw data to match Argo for EB results. See for example Loeb 2016.
“No, there is no energy gained by the surface molecule as it is at an already higher energy state than the incoming photon”
If there were no energy gained in this case then 1LOT would be broken. So your statement is incorrect Arfur. Measurements over the spectrum and a hemisphere of directions show of 100 random photons incident on Earth natural L&O surface about 95 will indeed be absorbed at the surface and about 5 reflected.
“Backradiation cannot heat the surface directly”
Correct, as the 95 incident photons (“backradiation” or “all sky emission to surface”) absorbed add their energy to the surface, the surface cooling is slowed. This process should not be confused with a heating process though that often happens. Solar SW can heat Earth surface & atm., atm. LW can only slow the surface cooling. So that night time surface liquid water in view of increased atm. LW is found warmer by thermometer experiment than water not in view of the increased LW, for example when a cloud goes by. Both waters in this experiment continuously cooling on Newton’s straight line on semi log paper.

Trick,
Many thanks for your clarification. On the point of the 0.6+/- 0.4 W/m2, do you consider this significant, as Rud does?
As to the 1LOT, why is it broken? There is no increase in internal (thermal) energy of the surface. If a cold object and a warm object are placed next to each other, the fact that they both radiate is not in question. But the heat flow is only one way: from hot to cold. If you now place a second cold object of the same temperature as the first next to the warm object, according to your comment there is now double the incoming energy (W/m2) being absorbed for energy gain by the warm object, so do you think the warm object will reduce its rate of cooling further? In which case, how many cold objects do you have to place next to a warm object before it actually gets hotter than it was?
Yes, the rate of cooling depends upon the temperature difference between the two objects and so, as the CO2 molecule warms (I know a single molecule can not be described as warm), the heat flow from the surface to it will reduce but as there are so few CO2 molecules in the atmosphere how much effect can this have on global temperature (whatever that is)? Consider also that the CO2 molecule emits as readily as it absorbs.
If 95% of back radiation is absorbed by the surface for energy gain, as you state, then even a small increase in CO2 will have a relatively large warming effect. This demonstrably has not happened. I don’t get wamrer by standing in from of a mirror… or four mirrors.
By the way, I very much respect your opinion, having seen you comment on other sites. So I am genuinely interested.

Arfur: “As to the 1LOT, why is it broken?”
Arfur incorrectly wrote: “there is no energy gained by the surface molecule” which breaks 1LOT. While measurements show 95 of the 100 random photons I mentioned are annihilated (absorbed) at the surface, their energy cannot be annihilated as the energy in the 95 is not reflected nor transmitted, the energy MUST then be gained by the surface molecules( s) by measurement. The 1LOT rules out annihilation of energy.
Thus Arfur is incorrect to write “There is no increase in internal (thermal) energy of the surface.”. Correctly written: There is an increase in internal (thermal) energy of the surface thus its temperature will not decline as fast.
“But the heat flow is only one way: from hot to cold.”
Arfur misuses 1800s terminology. In modern times science knows no object possesses heat. The kinetic energy of two objects in contact and/or each in view can be exchanged both ways. 2LOT mandates increase in universe entropy determines the net direction.
“If you now place a second cold object of the same temperature as the first next to the warm object..”
Again, to determine net KE flow between your three objects refer to: 2LOT mandates increase in universe entropy determines the net direction.
“so do you think the warm object will reduce its rate of cooling further?”
2LOT mandates increase in universe entropy determines the net direction. You aren’t real specific here but 2LOT mandates a yes answer from what I can understand of your setup, Arfur added kinetic energy to the system when you added the third colder object.
“In which case, how many cold objects do you have to place next to a warm object before it actually gets hotter than it was?”
2LOT mandates increase in universe entropy determines the net direction. No amount of colder objects will suffice, universe entropy must increase.
“as there are so few CO2 molecules in the atmosphere how much effect can this have on global temperature (whatever that is)? “
Think you mean global Tmedian. Your question is not clear, maybe you need to read up on ECS of which estimates abound. Pick your favorite.
“If 95% of back radiation is absorbed by the surface for energy gain, as you state,”
I didn’t write that, I wrote around 95 of 100 random photons incident on the Earth natural L&O surface will be absorbed, those 5 reflected are accounted for in the energy budgets.
Think you mean: “I don’t get warmer by standing in front of a mirror… or four mirrors.”
Correct, as your test shows you don’t get warmer, because 2LOT mandates increase in universe entropy determines the net direction of KE flow. In this case your mirror simply blocks the radiation from the wall behind it that would have been absorbed (and reflected) by you. Now the mirror has replaced the wall’s radiation.

No you’re wrong, the photon carries no information about its temperature of origin! The photon will excite the energy level of the recipient molecule to a higher energy level if the energy given up by the photon is an exact match for the energy difference between those two levels.

Trick,
Our posts are just going to get longer if we constantly repeat each others statements, so I will revert to keeping it simple and real:
The rate of cooling depends only upon the temperature difference between the hot and cold objects. Any increase in atmospheric temperature due to the addition of 280 CO2 molecules per million will not measurably change the temperature difference between the surface and space.
The 2LOT says absolutely nothing about ‘net radiation’. In simple terms, the Clausius statement reads that heat will only flow from hot to cold. Spin it whatever way you want. Net radiation is irrelevant. We are discussing global warming, not global net radiation. Radiation is not heat. The heat flow is only dependant on the temperature difference.
You stated quite clearly that the radiation from the colder object (atmospheric CO2 in this discussion) adds to the thermal energy of the absorbing surface. This does not happen, because then there would be heat flowing from cold to hot. Speak to Clausius.
You agree with me that no amount of cold objects can make a warm object even hotter, so why do you persist in saying that radiation from a cooler source adds thermal energy to the receiving surface?
The logical extension of your argument is that an old lady sitting in her living room freezing to death can make herself warmer by adding a few wooden chairs next to her, because then she will increase the incoming radiation which will reduce the ‘net KE flow’. In real life, she will not get warmer, and neither will the planet gain thermal energy in any measurable sense from a doubling of atmospheric CO2.
Oh, and as for ECS, I choose 0.01C +/- 0.009…
Keep it real.

I never said it did carry temperature information. However, it does carry an energy state which is dependant upon its frequency. If two identical objects at a different temperature emit photons, the higher energy of the photon from the hotter object is an indication of the emitter’s temperature.
And the only time a higher (thermal) energy level will be reached by the receiving surface is if the incoming photon possesses the required energy to elevate the ‘excitement’ level (your term). On the macro scale, this is portrayed by an increase in temperature of the surface. As heat only flows one from hot to cold, the higher thermal anergy level can not be reached by the absorption of a low energy photon.
It is easy to get bogged down in the micro (quantum) level but empirical evidence regarding global temperature is gained at the macro level.
There is no real evidence to suggest the existence of surface warming by backradiation.

3) Doesn’t understand 2LOT is an entropy law not a heat law thus relevant for the Earth/atm. system energy budgets which must increase universe entropy.
4) Doesn’t understand there is no heat in an object, not in the atm., ocean or dirt surface though there is a lot of constituent KE in each of those.
5) Doesn’t understand why there is no net cold to hot in anything I wrote as I used 1LOT object KE transfer and 2LOT for direction. Quote Clausius words, find that Clausius wrote consistent with there is no heat in an object only constituent KE.
6) Doesn’t understand I persist in writing radiation absorbed into an object becomes energy INTO that object consistent with 1LOT and 2LOT confirmed by experiment..
7) Doesn’t understand that adding wooden chairs (or mirrors) to a room is not the same as adding CO2 to Earth atm. Prof. Tyndall added CO2 to his experiment not wooden chairs (or mirrors).

Arfur 12:51pm: “If two identical objects at a different temperature emit photons, the higher energy of the photon from the hotter object is an indication of the emitter’s temperature.”
The identical objects at different temperatures emit photons of every wavelength (thus all energies) from experiment and theory Arfur. You did write colder, warmer. You cannot tell from which object any single photon originated, as Phil. told you, the photons carry no temperature information, only energy, momentum (linear and angular), polarization.
“the higher thermal energy level can not be reached by the absorption of a low energy photon.”
All experiments since Prof. Tyndall’s (and some earlier work) have shown the opposite Arfur. Or cite a single experiment showing what you write is correct.
“There is no real evidence to suggest the existence of surface warming by backradiation.”
Then you haven’t bothered to find it and you get confused misquoting Clausius, using terms like “heat” “warming”; suggest Arfur start with the 1861 experimental report by Prof. Tyndall on his many “hundreds” of experiments conducted in 1859, 1860 that “astonished” even him.

I never said it did carry temperature information. However, it does carry an energy state which is dependant upon its frequency. If two identical objects at a different temperature emit photons, the higher energy of the photon from the hotter object is an indication of the emitter’s temperature.

No, an object at 350K and one at 250K can both emit a 15μm photon, both photons will be absorbed by a blackbody at 300K equally well it has nothing to do with the temperature of the source. The observer has no way to tell the temperature of the source by the energy of an individual photon.
And the only time a higher (thermal) energy level will be reached by the receiving surface is if the incoming photon possesses the required energy to elevate the ‘excitement’ level (your term). On the macro scale, this is portrayed by an increase in temperature of the surface. As heat only flows one from hot to cold, the higher thermal anergy level can not be reached by the absorption of a low energy photon.
Yes it can and does,15μm photons incident on an absorber it will raise the energy of the absorber by ~8kJ/mole regardless of the temperature of the absorber.
It is easy to get bogged down in the micro (quantum) level but empirical evidence regarding global temperature is gained at the macro level.
There is no real evidence to suggest the existence of surface warming by back radiation.

There is plenty, a very direct one is the use of radiation shields in the use of thermocouples in flames. If you put a thermocouple in a flame you measure a lower temperature than the actual flame temperature due to loss to the surroundings by radiation. If you put a quartz radiation shield around the thermocouple the temperature measured goes up closer to the flame temperature because the radiation exchange with the shield involves ‘back radiation’ from the shield which is hotter than that from the previous surroundings. This is very old technology, so old it was the subject of NACA reports, i.e. before NASA.

On the macro scale, this is portrayed by an increase in temperature of the surface. As heat only flows one from hot to cold, the higher thermal anergy level can not be reached by the absorption of a low energy photon.
You continue to incorrectly associate the wavelength of the photon with temperature and falsely assume that such a ‘low energy photon’ can not be absorbed by a warm surface. In fact a photon of any wavelength can be absorbed as long as the appropriate energy level separation exists in the absorber.
Take for example an O3 molecule in the atmosphere, it can emit IR in the 9-10 micron range, by your definition that would be a ‘low energy photon’, however if I focus enough 10 micron photons on a steel plate I will melt it!
In answer to your statement:
There is no real evidence to suggest the existence of surface warming by back radiation.

Easy, you have a thermocouple heated by a hot gas flow it loses heat by radiating to its surroundings, the heat balance is given by:
h(Tgas-Ttc)= εσ(Ttc^4-Tamb^4)
An example using typical parameters where the measured temperature is 1100K and Tamb is 300K
gives a Tgas of 1185K an error of about 7%.
Put a shield around the thermocouple which then is itself heated up to say 1000K, now Tamb for the thermocouple is 1000K (the Tamb^4 term is ‘back radiation’ from a cooler object) and the measured temperature (Ttc) is much closer to the gas temperature (Tgas). So the temperature of the thermocouple has increased by being surrounded by a shield that is cooler than itself.
Dogma is a wonderful thing, isn’t it?
I’ll leave the dogma to you I’ll stick with the science.

3) See 1).
4) “I talked about heat flow” Wrongly since something that does not exist in an object cannot flow out of that object. KE exists in object; KE can flow out as object cools.
5) No strangeness, Clausius worked from his experiments and those of others to develop the 2LOT theory.
6) “Does the energy INTO the object cause the object to get warmer or not? Simple question…” Higher temperature by thermometer measurement than without the kinetic energy as Prof. Tyndall showed by thermopile and thermometer.
7) Third person? Actually Tyndall did experiment on whether the backradiation from these gasses then re-heated the object from which they first received the radiation as there were thermometers shown in his radiation source & monitored steady. 2LOT held.

Phil,
Firstly, I should have made my point more clearly, so thank you for making me realise that. Yes, any heat source can emit a photon of similar wavelengths. However, what I should have stated is that the average photon energy emitted from the warmer object is greater than the average photo energy from the cooler object. In addition, the SUM of energies from the warmer object is greater than that of the cooler object. I hope you can agree with that. Therefore, on average (which is what temperature is) the kinetic energy is greater associated with the warmer object. This means that, on average, a cooler object cannot heat (by radiate or any other transmission mechanism) a cooler object.
You continuously argue the microscopic whilst ignoring the macroscopic. Whereas there may well be photons of high energy emitted from any object, it is the average of the photons which are evidenced in the macroscopic world. This is the world of ‘global warming’. A single photon being absorbed by a surface is irrelevant to the overall temperature of the object. It is the cumulative sum (or average) that will denote whether a temperature rise will occur. I should have stressed this in my earlier comments.

Trick,
You are becoming tiresome. You cannot give a different quote from Clausius and then state that I have mis-quoted him! In his 1854 essay entitled ‘On a modified form of the second Fundamental Theorem in the Mechanical Theory of Heat’ (English translation 1856 page 86), Clausius states:
[“This principle, upon which the whole of the following development rests, is as follows: Heat can never pass from a colder to a warmer body without some other change, connected therewith, occurring at the same time.”]
If you are unable to accept this as a quote from Clausius then we have nothing further to discuss.
Further, you state, in response to me using the term ‘Heat Flow’:
[“Wrongly since something that does not exist in an object cannot flow out of that object. KE exists in object; KE can flow out as object cools.”]
Again, you are being obtuse to the point of ridiculousness. In the Entropy formula: delta S = delta Q divided by T, ask yourself what Q stands for. I agree that ‘heat’ cannot exist in an object but heat may be defined as the flow of energy (or energy in transfer) from a hot object to a colder object. Your statement “KE can flow out as object cools” is what would normally be termed as ‘heating’ the colder object.
Frankly, I don’t care if you want to side-track the point in meaningless jargon. The fact is – and I repeat – Heat cannot flow from Cold to Hot.
I will not respond further, so I wish you Season’s Greetings and a happy life.
Regards,
Arfur

Arfur – You can still learn from Clausius.
The 1854 quote you clip is not Clausius’ 2LOT. Many are misguided by your 1854 clip when they mistake that clip as the law, not you alone. That quote is derived from Clausius 2LOT. My point is your misquoting Clausius’ 2LOT causes you confusion when you invoke your 1854 clip as the law. You need to quote exactly the 2LOT and proceed your logic from there and you will find your confusions. You will find KE can flow from a lower temperature object to a higher temperature object and increase universe entropy consistent with 2LOT as Clausius wrote it contrary to your incorrect statement: “Heat can never pass from a colder to a warmer body.” Hint: Your study will find a need to invoke M-B distribution.
Q stands for kinetic energy flow in/out of an object (never heat) as Clausius clearly explained in his 1st memoir p. 18. Q adds a lot of confusion to your writing and that of others when you don’t define Q exactly as Clausius did. There is a lot of confusion that crept in behind on Q (even in many text books) and still exists today, I always urge reading the original authors which takes some work that many (most?) will not do & the confusion continues.

Phil,
Firstly, I should have made my point more clearly, so thank you for making me realise that. Yes, any heat source can emit a photon of similar wavelengths. However, what I should have stated is that the average photon energy emitted from the warmer object is greater than the average photo energy from the cooler object. In addition, the SUM of energies from the warmer object is greater than that of the cooler object. I hope you can agree with that. Therefore, on average (which is what temperature is) the kinetic energy is greater associated with the warmer object.

So far so good.
This means that, on average, a cooler object cannot heat (by radiate or any other transmission mechanism) a cooler object.
I guess you meant warmer here? It’s not true, the warmer body will increase its temperature as the cooler body with which it is in equilibrium increases its temperature.
You continuously argue the microscopic whilst ignoring the macroscopic. Whereas there may well be photons of high energy emitted from any object, it is the average of the photons which are evidenced in the macroscopic world. This is the world of ‘global warming’. A single photon being absorbed by a surface is irrelevant to the overall temperature of the object. It is the cumulative sum (or average) that will denote whether a temperature rise will occur. I should have stressed this in my earlier comments.
But the photons are acting at the individual level, we constantly see convoluted arguments here that a photon emitted from a cooler body can not by some mysterious means be absorbed by the warmer body which is absolute bunk. You’ve got to get the microscopic right to get the whole right.
Secondly, [“I’ll leave the dogma to you I’ll stick with the science.”]
The problem is you are not taking the holistic view. Science, at its most basic, has to make sense. That is why it was invented – to make sense of the real world. By just looking at the trees and not seeing the forest, you limit your world view and hide behind “oh, but I’m just doing science”.

ECS (in any significant sense) is an assumption, not fact.

Quantum mechanics doesn’t make sense to some, including Einstein at one point but it is correct and necessary to understand the process.
As I said to you – and the thermocouple experiment proves your view, even though you did not answer me earlier – you are now trying to make the case that CO2 is an insulator. If you insulate against heat loss you will reduce heat loss but you will not make the source hotter.

Remove 99.96% of the radiation shield and repeat the experiment.
Why would I remove 99.96% of the CO2? 99.96% of the atmosphere is transparent to IR and has no part in the radiative interaction. If I double the CO2 it’s the same as increasing the emissivity of the radiation shield which would increase the temperature of the thermocouple.

Phil,
You keep talking about your radiation shield but you don’t provide any evidence that ‘backradiation’ actually works.
I read your NACA TN 2599 and it only mentions a shield once (and it says nothing about Quartz). Here is the text:
[“”The thermocouple is initially shielded from the hot gases by a tube through which cooler air is blown. The tube is suddenly removed, exposing the unit to the hot gases. The response is shown in Fig 5.”]
Figure 5 shows that the temperature of the thermocouple rises once the tube has been removed! Help me out here please. Can you please give an exact reference to support your claim re backradiation?
You also state:
[“Easy, you have a thermocouple heated by a hot gas flow it loses heat by radiating to its surroundings, the heat balance is given by:
h(Tgas-Ttc)= εσ(Ttc^4-Tamb^4)
An example using typical parameters where the measured temperature is 1100K and Tamb is 300K
gives a Tgas of 1185K an error of about 7%.
Put a shield around the thermocouple which then is itself heated up to say 1000K, now Tamb for the thermocouple is 1000K (the Tamb^4 term is ‘back radiation’ from a cooler object) and the measured temperature (Ttc) is much closer to the gas temperature (Tgas). So the temperature of the thermocouple has increased by being surrounded by a shield that is cooler than itself.”]

No, you have insulated the thermocouple (which I have mentioned several times now) and then provided a source of energy into the thermocouple! Of course it will heat up! So, I repeat, are you claiming atmospheric CO2 is an insulator?

So the temperature of the thermocouple has increased by being surrounded by a shield that is cooler than itself.
It’s just closer to the actual temperature of the flame. The flame isn’t any warmer.

In this analogy the flame is the sun (the ultimate source of heat), the thermocouple is the earth (heated by the sun and cools by radiation with its surroundings), and the radiation shield is the atmosphere. I was asked to give an example of an object being heated via ‘back radiation’, I did so, one that’s used by engineers on a daily basis.

December 11, 2016 2:29 pm

In TS.6 IPCC AR5 admits they don’t know.
References:
Trenberth et al 2011jcli24 Figure 10
This popular balance graphic and assorted variations are based on a power flux, W/m^2. A W is not energy, but energy over time, i.e. 3.4 Btu/eng h or 3.6 kJ/SI h. The 342 W/m^2 ISR is determined by spreading the average 1,368 W/m^2 solar irradiance/constant over the spherical ToA surface area. (1,368/4 =342) There is no consideration of the elliptical orbit (perihelion = 1,416 W/m^2 to aphelion = 1,323 W/m^2) or day or night or seasons or tropospheric thickness or energy diffusion due to oblique incidence, etc. This popular balance models the earth as a ball suspended in a hot fluid with heat/energy/power entering evenly over the entire ToA spherical surface. This is not even close to how the real earth energy balance works. Everybody uses it. Everybody should know better.
An example of a real heat balance based on Btu/h is attached. Basically (Incoming Solar Radiation spread over the cross sectional area) = (U*A*dT et. al. leaving the lit side perpendicular to the spherical surface ToA) + (U*A*dT et. al. leaving the dark side perpendicular to spherical surface area ToA) The atmosphere is just a simple HVAC heat balance problem.
http://earthobservatory.nasa.gov/IOTD/view.php?id=7373
“Technically, there is no absolute dividing line between the Earth’s atmosphere and space, but for scientists studying the balance of incoming and outgoing energy on the Earth, it is conceptually useful to think of the altitude at about 100 kilometers above the Earth as the “top of the atmosphere.” The top of the atmosphere is the bottom line of Earth’s energy budget, the Grand Central Station of radiation. It is the place where solar energy (mostly visible light) enters the Earth system and where both reflected light and invisible, thermal radiation from the Sun-warmed Earth exit. The balance between incoming and outgoing energy at the top of the atmosphere determines the Earth’s average temperature. The ability of greenhouses gases to change the balance by reducing how much thermal energy exits is what global warming is all about.”
ToA is 100 km or 62 miles. It is 68 miles between Denver and Colorado Springs. That’s not just thin, that’s ludicrous thin.
The GHE/GHG loop as shown on Trenberth Figure 10 is made up of three main components: upwelling of 396 W/m^2 which has two parts: 63 W/m^2 and 333 W/m^2 and downwelling of 333 W/m^2.
The 396 W/m^2 is determined by inserting 16 C or 279K in the S-B BB equation. This result produces 55 W/m^2 of power flux more than ISR entering ToA, an obvious violation of conservation of energy created out of nothing. That should have been a warning.
ISR of 341 W/m^2 enter ToA, 102 W/m^2 are reflected by the albedo, leaving a net 239 W/m^2 entering ToA. 78 W/m^2 are absorbed by the atmosphere leaving 161 W/m^2 for the surface. To maintain the energy balance and steady temperature 160 W/m^2 rises from the surface (0.9 residual in ground) as 17 W/m^2 convection, 80 W/m^2 latent and 63 W/m^2 LWIR (S-B BB 183 K, -90 C or emissivity = .16) = 160 W/m^2. All of the graphic’s power fluxes are now present and accounted for. The remaining 333 W/m^2 are the spontaneous creation of an inappropriate application of the S-B BB equation violating conservation of energy.
But let’s press on.
The 333 W/m^2 upwelling/downwelling constitutes a 100% efficient perpetual energy loop violating thermodynamics. There is no net energy left at the surface to warm the earth and there is no net energy left in the troposphere to impact radiative balance at ToA.
The 333 W/m^2, 97% of ISR, upwells into the troposphere where it is allegedly absorbed/trapped/blocked by a miniscule 0.04% of the atmosphere. That’s a significant heat load for such a tiny share of atmospheric molecules and they should all be hotter than two dollar pistols.
Except they aren’t.
The troposphere is cold, -40 C at 30,000 ft, 9 km, < -60 C at ToA. Depending on how one models the troposphere, average or layered from surface to ToA, the S-B BB equation for the tropospheric temperatures ranges from 150 to 250 W/m^2, a considerable shortfall from 333.
(99% of the atmosphere is below 32 km where energy moves by convection/conduction/latent/radiation & where ideal S-B does not apply. Above 32 km the low molecular density does not allow for convection/conduction/latent and energy moves by S-B ideal radiation et. al.)
But wait!
The GHGs reradiate in all directions not just back to the surface. Say a statistical 33% makes it back to the surface that means 50 to 80 W/m^2. A longer way away from 333.
But wait!
Because the troposphere is not ideal the S-B equation must consider emissivity. Nasif Nahle suggests CO2 emissivity could be around 0.1 or 5 to 8 W/m^2 re-radiated back to the surface. Light years from 333.
But wait!
All of the above really doesn’t even matter since there is no net connection or influence between the 333 W/m^2 thermodynamically impossible loop and the radiative balance at ToA. Just erase this loop from the graphic and nothing else about the balance changes.
BTW 7 of the 8 reanalyzed (i.e. water board the data till it gives up the right answer) data sets/models show more power flux leaving OLR than entering ASR ToA or atmospheric cooling. Trenberth was not happy. Obviously, those seven data sets/models have it completely wrong because there can’t possibly be any flaw in the GHE theory.
The GHE greenhouse analogy not only doesn’t apply to the atmosphere, it doesn’t even apply to warming a real greenhouse. (“How Global Warming was Discovered” Spencer Weart) It’s the physical barrier of walls, glass, plastic that traps convective heat, not some kind of handwavium glassy transparent radiative thermal diode.
The surface of the earth is warm for the same reason a heated house is warm in the winter: Q = U * A * dT, the energy flow/heat resisting blanket of the insulated walls. The composite thermal conductivity of that paper thin atmosphere, conduction, convection, latent, LWIR, resists the flow of energy, i.e. heat, from surface to ToA and that requires a temperature differential, 213 K ToA and 288 K surface = 75 C.
The flow through a fluid heat exchanger requires a pressure drop. A voltage differential is needed to push current through a resistor. Same for the atmospheric blanket. A blanket works by Q = U * A * dT, not S-B BB. The atmosphere is just a basic HVAC system boundary analysis.
Open for rebuttal. If you can explain how this upwelling/downwelling/”back” radiation actually works be certain to copy Jennifer Marohasy as she has posted a challenge for such an explanation.

The analogy is false, so requires no response. The GHE does not work like a thermal ‘blanket’ which impedes convection. It impedes thermal,radiative cooling, an altogether different physical proposition.
Separately, themwhole Venus gravitational potential argument is wrong from first principles. Too boring to rehash gain here, For you, consider the definition of ‘work’ energy and the whole BS skydragon idea automatically’fails. Please grok simple basic physics ideas.

Wasn’t the Venus temperature explained in a past post here on WUWT? I recollect, that it had to do with the much higher atmospheric density (compared to earth), the much higher pressure and the barometric height formula. As I understand it, at some height in the Venus atmosphere there is a radiation balance between incoming solar radiation and outgoing thermal radiation; it is where the atmosphere becomes optically thick (looking from outer space). The atmospheric layer at that height has some equilibrium temperature but from there down to the Venus surface the atmosphere will heat up substantially, one could calculate this with the atmospheric height formula under the assumption of an adiabatic atmosphere, for example. But this is not my field of expertise…

Nicholas Schroeder,
0.04% concentration of CO2 in the atmosphere is even enough that every IR ray – being radiated from the surface – will hit one CO2 (or another GHG) molecule after 20 to 100 Meters, one wise man told me.
And then the game starts: The molecule is “heated up”, and giving away the heat by contact to another atmospheric molecule or radiating in a random direction, which is half up or half down (in distinct angles). That IR ray is hitting another molecule, heating it up as well, and so on.
If an O2 or a N2 molecule is heated up by contact it will eventually contact a CO2 or a H2O molecule which radiates again in a random direction. As the atmosphere gets thinner towards top of atmosphere, there is more and more space between the molecules, so the IR rays can pass a longer distance without disturbance, finally radiating into the space.
If the concentration of GHG molecules is higher, then the ping-pong game lasts a bit longer, means a stronger delay.
This is the story, as I as a layman unterstands it.

Nicholas 2:29 pm – “Open for rebuttal.”
Good for you Nicholas. There is plenty to rebut, you only need to follow your own source. My rebuttal is not original, entirely from the source you mention.
“There is no consideration of the elliptical orbit (perihelion = 1,416 W/m^2 to aphelion = 1,323 W/m^2)”
Incorrect, your 1368 considers the avg.d orbital parameters.
“There is no consideration of…day or night or seasons”
Incorrect, the 1368 is from observations 24/7/365. All seasons, day and night, from ~4 annual periods.
“upwelling of 396 W/m^2 which has two parts: 63 W/m^2 and 333 W/m^2”
Incorrect, there is only one part, total 396 radiated from the near surface atm. global Tmedian of about 289K for the observation period in TFK09.
“The 396 W/m^2 is determined by inserting 16 C or 279K in the S-B BB equation.”
Incorrect, the 396 comes from the energy balance at the surface Tmedian about 289K considering measured global atm. emissivity ~0.8 over the period observed.
“This result produces 55 W/m^2 of power flux more than ISR entering ToA, an obvious violation of conservation of energy created out of nothing.”
Incorrect, the surface balances per 1LOT higher than just TOA SW ASR in TFK09 to include the atm. hemispherical LW glow incident on L&O surface in addition to the ASR, again, avg.d over the orbit and ~4 annual periods.
“The remaining 333 W/m^2 are the spontaneous creation of an inappropriate application of the S-B BB equation violating conservation of energy.”
Incorrect, the 333 is the all sky emission to surface as in TFK09 as you write 78+17+80+158=333. All in balance except for the 0.9 absorbed over the 4+ annual periods observed.
“The 333 W/m^2 upwelling/downwelling constitutes a 100% efficient perpetual energy loop violating thermodynamics.”
This is steady state, as such is not a violation of thermodynamics. Process is not 100% efficient, the sun is needed burning a fuel to keep it all going.
“The 333 W/m^2, 97% of ISR, upwells into the troposphere where it is allegedly absorbed/trapped/blocked by a miniscule 0.04% of the atmosphere.”
Hardly. The 396 radiated is absorbed/transmitted/reflected by the entire atm. depth, all its constituents in ~steady state for the period observed.
“The GHGs reradiate in all directions ”
So does the balance of the atm., in all 333 all sky emission to surface over a hemisphere of directions not just the much smaller solar diameter.
“Nasif Nahle suggests”
A suggestion by anyone is not a proper observation with a radiometer/thermometer as in TFK09.
“Just erase this loop from the graphic and nothing else about the balance changes.”
Erase up/down drafts? Erase evaporation? There sure are changes.
“It’s the physical barrier of walls, glass, plastic that traps convective heat”
No convection escapes to space from earth, barely makes it above the tropopause, you know, like a greenhouse.
“copy Jennifer Marohasy as she has posted a challenge for such an explanation.”
I’ll leave that to Nicholas once you understand your own source, send her a copy of TFK09, Stephens 2012, include about 100 similar Earth energy balance papers over the years.

“It has been discussed many times on this site, and I think it is right, that the feedback from water vapour is negative. That is, any additional heating by extra CO2 causes more evaporation, which blocks the sun & reduces the energy input.”
But even if that’s not true, the additional water vapour in the atmosphere can only get there by the phase change process known as evaporation. Evaporation has the effect of cooling the surface, so as a CO2 GHE response evaporation will exchange sensible heat for latent heat. IOW, energy levels in the atmosphere are increasing faster than sensible heat measurements indicate.
So water vapour provides a negative feedback as far as humans are concerned WRT observed instrumental temperature, even if related cloud feedbacks have a 0 effect on global albedo,

water vapour cools by day, because of clouds blocking sunlight, and warms by night as clouds insulate radiation that might escape to space and so on. That’s why deserts are hot by day and cold by night.
There is no easy answer as to what the net effect is, especially since at least one WUWT contributor has shown that tropical clouds and storms are correlated with the time of day.

December 11, 2016 2:56 pm

I could say a lot and have at CoSy.com , but I’ll just note that any computations of temperature at the bottoms of atmospheres versus their tops which does not account for the rather straightforwardly calculable difference in gravitational energy is incomplete .
I strongly dislike the phrase “effective black body temperature” because it contributes to the mistaken notion that a gray , ie : flat spectrum , body no matter how dark or light comes to the same temperature . Either a term like “colored body” or “radiative balance” temperature would be much closer to the physical reality being described . It is the correlations of the spectra of the body with its radiant sources an sinks and the use of a scalar “emissivity” as opposed to actual computations between the relevant spectra leads to much confusion .
As someone who has been involved in satellites , it would be nice to get a confirmation that a gray painted object in our orbit comes to a temperature of about 279 , about 5c not255K . I’ve seen that the design temperature for instrument packages on at least 1 satellite system matches this gray body calculation and it should be ubiquitous including calculating the energy budget for the space station .
