Renwick distorts evidence

Auckland mayoral candidate Vic Crone

During an interview a few days ago, Auckland mayoral candidate Vic Crone would not say if she believed the earth was warming due to man-made pollution, saying only: “Gosh, that’s a very contentious debate.”

Dr James Renwick, a professor of physical geography at Victoria University of Wellington, has slammed Crone’s statement. “The climate is changing and it is due to human activity and that is very clear from all sorts of lines of evidence,” he said. “To say that it’s very contentious suggests a real lack of understanding of the area.” The evidence showed that human influence was the dominant cause of global warming, Renwick said. “To try and say that we’re not sure is very backward thinking.” [emphasis added]

But that’s just not the case.  The IPCC make no such categorical statements and official reports are actually soaked in uncertainty. It seems Professor Renwick’s certitude is at odds with the science. Still, perhaps NIWA states things more confidently. So I searched the NIWA web site in an attempt to corroborate this no-nonsense, activist-oriented doctrine that is convinced we cause all or most climate change. I typed ‘climate change evidence anthropogenic’ in the search box and got ten results. But none supported Renwick’s brusque response to Miss Crone. These are the NIWA articles the search returned:

  1. Understanding past changes in the Southern Ocean
  2. Climate change, global warming and greenhouse gases
  3. Greenhouse gases and climate sensitivity – insights from ice cores
  4. Climate Change
  5. IPCC Fourth Assessment Report (2007)
  6. New Zealand in a warming world
  7. Global climate models
  8. Our Far South events
  9. NIWA says greenhouse gas methane is on the rise again
  10. The WMO/UNEP 2002 ozone assessment: a New Zealand perspective

I should say there were no surprises here, and NIWA make it no easier to understand anthropogenic climate change since 2009 (when we challenged the national temperature data published on their web site), they make it more difficult. All these articles confuse the reader seeking the cause of human climate change, apparently presenting material only to obscure the lack of evidence. They are, in the legal terminology, prolix.

No. 1 Understanding past changes in the Southern Ocean

Not relevant. Learning about natural climate change so we can recognise anthropogenic climate change when (and if) it occurs.

No. 2 Climate change, global warming and greenhouse gases

Some relevance. An interesting summary but fails to explain how humanity is the cause of global warming and thus of climate change, although it comes close [my emphasis]:

Have greenhouse gas emissions caused global temperatures to rise?

  • Greenhouse gas concentrations have continued to increase in the atmosphere. This is due largely to human activities, mostly fossil fuel use, land-use change, and agriculture. About 47% of the warming effect of greenhouse gas increases over the last 100 years is due to carbon dioxide.

  • The second most important greenhouse gas produced by human activities is methane, which accounts for about 35% of the increased warming over the past 100 years (this is an important aspect of New Zealand’s greenhouse gas emissions, since sheep and cows produce methane).

  • Warming by greenhouse gases is offset in some regions by cooling due to small airborne particles generated by burning fuel. These are concentrated around areas of industrial activity in the Northern Hemisphere and in developing countries. (The cooling effect of aerosols over the New Zealand region is expected to be small).

  • Global mean surface temperature increased by 0.74°C between 1906 and 2005, a change which is unlikely to be entirely natural in origin. The balance of evidence suggests a discernible human influence on global climate. Much of the 1.8±0.5 mm yr-1 average global sea level rise between 1961 and 2003 may be related to the rise in global temperature.

These are oily words in weasel expressions shaped in the manner of scientific conclusions but in fact only invitations to draw our own. But NIWA is openly uncertain: the expressions “due largely to human activities”, “about 47% of the warming … is due to carbon dioxide”, “unlikely to be entirely natural” and “a discernible human influence” are incompatible with Renwick’s inflated assertions that it is due [implying ALL due] to human activity.

His most outrageous claim was human influence was the dominant cause of global warming. He used this unscientific statement to belittle Vic Crone’s “lack of understanding”, but I’m curious to know the data that justifies the extraordinary statement.

These public documents don’t corroborate Renwick’s overblown certainty. He says disparagingly: “To say that we’re not sure is very backward thinking.” But an examination of the scientific sources shows our mayoral candidate is absolutely correct to express doubt. The only reason for Renwick to disparage this is that he disagrees with it. Which is no justification for presenting that disagreement as scientific fact.

No. 3 Greenhouse gases and climate sensitivity – insights from ice cores

Not relevant. Ice core research.

No. 4 Climate change

Not relevant. Though it claims that “most” of the increase in temperature since 1950 was due to the increase in our emissions of carbon dioxide, and that came from “a vast array of evidence” and “physics”, it goes on simply to describe the consequences of climate change.

No. 5 IPCC Fourth Assessment Report

Not relevant. There are 14 references to increased emissions of the accursed substances carbon dioxide (CO2), methane (CH4) and nitrous oxide (N2O), their change over time and their respective contributions to radiative forcing, and two references to aerosols and albedo citing tiny negative radiative contributions. There’s one reference to “new and stronger evidence that most of the warming observed over the last 50 years is attributable to human activities.” But there’s no mention of what that evidence might be.

No. 6 New Zealand in a warming world

Not relevant. Looks at the consequences of warming.

No. 7 Global climate models

Not relevant. Looks at the skill of models. Aptly, it asks “How Well do Models Simulate Observed Features of the Climate?” (exactly what we wanted to know). It says the Atmospheric Model Intercomparison Project (Gates, 1992) was to document the performance of GCMs in simulating the contemporary climate. Perfect! But inaptly, it gives us no results at all, saying very weakly that this has all been described at the First AMIP Scientific Conference (AMIP, 1995), and that “results have also been reported extensively in the open literature and in IPCC assessments.” So we’re on our own. When I have a little free time…

No. 8 Our Far South events

Not relevant. A glorious photographic celebration of NIWA research.

No. 9 NIWA says greenhouse gas methane is on the rise again

Not relevant. Describes our methane emissions and claims that methane affects temperature, but doesn’t describe how.

NIWA’s web page mentions methane (CH4) because farmed livestock, especially cattle and sheep, produce large quantities of it. What NIWA doesn’t say is that livestock are part of a cycle; when the herd or flock size is stable, there’s no change in the climate forcing from their methane. That’s before considering the inflated CO2 equivalence assigned to CH4. Methane is measured in parts per billion by volume (ppbv) because there’s so little of it in the atmosphere. Right now its concentration is about 1850 parts per billion, which is only 1.85 parts per million. So atmospheric methane, at 4,300,000,000,000 kg (4.3 billion tonnes) has less mass than a 500th part of the atmospheric mass of carbon dioxide (2.3 × 1012 (2,300 billion) tonnes). It is indeed far-fetched to imagine the tiny mass of methane having any thermal influence on the 5,150,000,000,000,000,000 kg (5.15 quadrillion tonnes) of the whole atmosphere. [12:00 noon 19 Sep 2016 – corrected conversion error; recalculated methane’s fraction of atmospheric carbon dioxide using mass, not volume. Thanks, Robin. – RT]

In the last 28 years CH4 has risen from 1675 ppbv to 1850 ppbv, or about 10%. This graph, though it ends in 2009, illustrates the strong increase in atmospheric methane since industrialisation began. Notice that the vertical axis doesn’t begin at 0, it begins at 600, which exaggerates the recent increase. Also, given the infinitesimal amount of atmospheric methane, you could double it a few times more without the climate noticing.

No. 10 The WMO/UNEP 2002 ozone assessment: a New Zealand perspective

Not relevant. Ozone is weird.

NIWA make it hard on their web site to find the link between human activities or emissions and global warming or climate change. It’s as though they don’t want to reveal the details, because the details are doubtful.

But this is a matter that requires substantial public resources. Fighting climate change requires, apparently, decades of effort, many millions of expenditure and deep changes to our industrial infrastructure.

It really is not too much to expect that our publicly-funded scientists will be open with us. What’s it to be, James?

    Spencer – “the fact that downwelling IR from the sky can be measured, and amounts to a level (~300 W/m2)………”

    Good grief. We all know DLR can be measured and is a radiative parameter. We know DLR is more than CO2 and WV radiating and in fact CO2 is a minor component (2%). We know the AIR mass radiates at T^4 in accordance with S-B. We know diurnal solar power drives the diurnal AIR temperature cycle and therefore the DLR cycle which is simply a fluctuation about the base T^4 radiation of AIR of which 99% is nitrogen and oxygen.

    We know there was never any recourse to a radiative “greenhouse effect” to establish the entire atmospheric temperature profile.

    We also know OLR can be measured. We know OLR is greater than DLR. And we know the difference is the radiative heat flux from surface up. We know there is no heat flux down, and that would be a violation of the Second Law anyway. There is no net LW heat flux into the surface. That’s solar SW.

    >”……….that can be scarcely be ignored; the neglect of which would totally screw up weather forecast model runs if it was not included; and would lead to VERY cold nights if it didn’t exist;”

    What numbskull reasoning. Why isolate DLR but not OLR? OLR cannot be ignored any less than DLR. The entire AIR mass cannot be ignored either (apart from its necessity for life). It would lead to VERY cold nights too if it didn’t exist, about -173 C.

  8. Dennis,

    ‘Secondly, not finding a “hotspot” does not show the theory wrong; perhaps the theory or the understanding incomplete.’

    Now you’re getting it Dennis!! CO2 warms a MAXIMUM of 1.2C per doubling of total (i.e. not just man’s) atmospheric CO2, but half the predicted warming is missing due to the empirically proven fact from multiple sources that positive feedback from water vapour is a non event, which is why all the climate models have failed as well – cause & effect.

    Without a positive feedback from water vapour, AGW simply isn’t a problem because CO2 as a greenhouse gas is too weak to cause any real damage on it’s own. I don’t doubt AGW as a result of CO2 exists, it’s just so weak that it’s not worth worrying about.

    All you have to do is compare the theory to the observations, and the empirical observations have falsified the theory. It’s not difficult at all.

  9. Dennis – ‘We’ve already seen radical warming. How much more do you want?

    A 40% increase of CO2 in the atmosphere. Earth has retained enough “extra” energy to drive mean global temperature up 1C in a few years and melted a significant amount of ice. That’s a radical change in climate. The difference between ice sheets covering Europe/America and dinosaurs living on Antarctica is … how many degrees?

    Earth has not reached a steady state yet. Has it. So there’s more warming to come. Isn’t there.

    And there’s more CO2 to come. Isn’t there. Lots. So more warming. Isn’t there. Lots.

    Water vapour is a non-event? That’s a new one. WV reckoned to contribute 50%; CO2 20%. You know what, I’ll go with the science, not wishful thinking.

    Without the greenhouses gases the International Standard Atmosphere would be quite different. For a start water on land would be ice and not much water vapour in the air. Oceans ice and slush maybe.

    But you could still be able to construct a Standard Atmosphere, a “new” ISA.

    Non sequitur.

    Theoretical anthropogenic radiative forcing (RF) generates several 100s of ZetaJoules MORE energy than was actually retained. the atmosphere is negligible in this respect. The IPCC’s anthro ocean warming attribution-by-speculation being outright scientific fraud.

    Solar SSR accounts for the “extra” energy in the ocean. There hasn’t been any “extra” now since March 2013.

    BTW Dennis.

    Did “greenhouse” gasses “trap” the El Nino heat?

    RSS
    http://woodfortrees.org/plot/gistemp/from:2015

    At the anomalies, 2015.5 0.72, 2016.08 1.32 and 2016.42 0.8, the amount of heat that represents can be determined by:

    Q = m•C•ΔT:

    Measuring the Quantity of Heat
    http://www.physicsclassroom.com/class/thermalP/Lesson-2/Measuring-the-Quantity-of-Heat

    Obviously the only change was ΔT. So Q increased from 2015.5 to 2016.08 but then decreased from 2016.08 to 2016.42.

    It is readily apparent that the heat Q at 2016.08 was not “trapped” in the troposphere but dissipated freely to space. If not space where did it go? It came from the ocean, it didn’t go back there.

    Where did the El Nino heat go Dennis?

    No it wouldn’t Dennis. Trace gasses are negligible. Only CO2 is required for perfect closure. Radaitive properties are of no account in the Std Atm.

    >”But you could still be able to construct a Standard Atmosphere, a “new” ISA.”

    Huh? What organization around the world is doing that Dennis? It is completely unnecessary. If you want to see what a small change in temperature at any altitude (e.g. weather, climate) makes to the other outputs then you just “offset”:

    >”The “ISA” you witter on about does NOT explain why Earth is at +15 not -18.>

    So what? It doesn’t have to Dennis. Std Atm establishes the surface temperature at 15.000 C irrespective of radiative transfer – Period.

    The entire earth’s AIR mass explains why the earth does not have the moon’s temperature.

    How does “GHE” explain the 188 K difference between an earth’s surface without an AIR mass assumed to be as the moon on dark side (100.15 K) and the surface temperature with an AIR mass (288.15 K) ?

    And,

    How does “GHE” explain the 85 K difference between an earth’s surface without an AIR mass assumed to be as the moon on sun side (373.15 K) and the surface temperature with an AIR mass (288.15 K) ?

    Feel free to change 288.15 K up (day) and down (night), and the 188 and 85 K differences as appropriate.

    Bunkum and humbug. ISA purports to do no such thing. It is a description of the atmosphere as found.

  23. Dennis,

    The IPCC’s AR5 shows the lower troposphere warming faster than the upper troposphere, the opposite of what was supposed to happen to prove positive feedback from water vapour – all temperature datasets agree.

    ‘Rather, it is the response of tropospheric water vapour to warming itself – the water vapour feedback – that matters for climate change. In GCMs, water vapour provides the largest positive radiative feedback (see Section 8.6.2.3): alone, it roughly doubles the warming in response to forcing (such as from greenhouse gas increases).’

    and:

    ‘the largest fractional change in water vapour, and thus the largest contribution to the feedback, occurs in the upper troposphere. In addition, GCMs find enhanced warming in the tropical upper troposphere, due to changes in the lapse rate (see Section 9.4.4).’

    Source: Box 8.1, AR4 http://www.ipcc.ch/publications_and_data/ar4/wg1/en/ch8s8-6-3-1.html

    The IPCC states that water vapour should double the effects of CO2. Guess what happens when there’s no positive feedback from water vapour? Half the predicted warming doesn’t exist, which is why the climate models have failed.

    Cause and effect dear boy, it really is quite simple. Would you like me to provide the empirical evidence from the AR5 showing the lower troposphere warming faster than the upper troposphere as well?

    Dennis thinks that CO2 is going to do all the warming by itself, which is truly hilarious.

    Yes, I know the history of the de Freitas paper.

    As Dennis Horne well knows, my interest in climate change in NZ revived when NIWA made a fuss about the Salinger thesis. My husband and I presented our Ph.D theses at Victoria around the same time that Salinger did. When we were contacted by VUW library some 20 or so years later to see if we would consent to having our theses digitised and put online, we readily agreed. I assume this is standard practice nowadays.
    I’ve never been able to figure out why Salinger insisted his thesis remained on closed reserve.

    My view is that all research (by staff & Grad students) conducted at NZ universities should be in the public domain, and be free and accessible.

    So this is driven by some lack of compliance to your personal rule about digitising old forgotten theses. Well, maybe not all ignored. Salinger’s might have been “chosen” by the powerful lobby driving the business-as-usual burning of fossil fuels. Especially as “Salinger” appears in Nature. And we know what a bunch of lying rrrs holes the lobbyists are – look at “Climategate” beat-up.

    Richard C (NZ) is spouting complete nonsense. [So, refute it or ignore it; your constant whining about it is irritating and does no good. – RT] That you can’t see that means you’re in over your head in crank poo.

  33. Dennis, give us one piece of evidence that the fossil fuel lobbyists were involved in Climategate. Any one will do

    Do you also believe that Israel is responsible for 9/11?

    Just asking

  34. Dennis dear boy,

    I’m not asking you to believe my personal interpretation because I don’t have one, I’m just pointing out the empirical evidence from all sources presented in the IPCC AR5 that contradicts what the IPCC says should be evidence of positive feedback from water vapour. That and the failed models, also presented in the IPCC.

    Your list of names from the IPCC is very impressive, which leads me to wonder why you reject the empirical evidence they present in the AR5, or their definition of why the upper troposphere is supposed to warm faster than the lower troposphere/surface as evidence of positive feedback from water vapour. Don’t you believe what they say? Which part do you reject, the IPCC’s empirical evidence or their definition of evidence?

    It really is a no-brainer for even the least of discerning minds Dennis. Cognitive dissonance perhaps?

    New Zealand was one of the first countries in the Southern Hemisphere to establish an official nationwide system of weather records. These records provide a rare long time series for temperatures in the Pacific Ocean, informing the data sparse interpolations required for early temperature series. Extant 1868 archives record the national normal mean surface temperature at 13.1 °C (when converted from degrees Fahrenheit) being the average of 10+ years read at six representative weather stations. Another major compilation, covering 35 years and based on nine stations, was published by the Dominion Meteorologist in 1920, which showed that the country’s average temperature has remained remarkably stable since records began. In 2010, the National Institute for Water and Atmospheric Research (NIWA) assessed the current national normal at 12.74 °C being the average of 30 years read at seven stations.

    On the face of it, New Zealand’s long-term mean temperature has remained relatively stable at 12.6 °C over the past 150 years.

    Same in Australia. The mid to late 1800s measurements are recorded but BOM ignores them for ACORN-SAT. They show the climate regime was similar to now with a cool period in between as in NZ.

    Long-term temperature record [but only from 1910]

    “Climate records, like this one from September 1887, are archived by the Bureau of Meteorology”

    http://www.bom.gov.au/climate/change/acorn-sat/documents/About_ACORN-SAT.pdf

    BOM then compiles a series from 1910 similar to NZ and adjusts the early raw data beyond all recognition.

    Hence:

    “The new data show that Australia has warmed by approximately one degree since 1910. The warming has occurred mostly since 1950.”

    Never mind the cooling since the late 1800s as in NZ.

    >[THS] “…take[s] the estimated effective surface temperature and then applies that temperature to a point halfway up the troposphere”

    Baloney. He does no such thing Simon. You are confusing some “effective surface temperature” (whatever that is) with ERL.

    Step 1: Derivation of the dry adiabatic lapse rate from the 1st Law of Thermodynamics and ideal gas law:

    Step 2: Determine the height at the center of mass of the atmosphere [and ERL]

    Step 3: Determine the surface temperature

    For Earth, surface pressure is 1 bar, so the ERL is located where the pressure ~0.5 bar, which is near the middle of the ~10 km high troposphere at ~5km. The average lapse rate on Earth is 6.5C/km, intermediate between the 10C/km dry adiabatic lapse rate and the 5C/km wet adiabatic lapse rate, since the atmosphere on average is intermediate between dry and saturated with water vapor.

    Plugging the average 6.5C/km lapse rate and 5km height of the ERL into our equation (6) above gives

    T = -18 – (6.5 × (h – 5))

    Using this equation we can perfectly reproduce the temperature at any height in the troposphere as shown in Fig 1. At the surface, h = 0, thus temperature at the surface Ts is calculated as

    Ts = -18 – (6.5 × (0 – 5))

    Ts = -18 + 32.5

    Ts = 14.5°C or 288°K

    which is the same as determined by satellite observations and is ~33C above the equilibrium temperature with the Sun.

    Thus, we have determined the entire 33C greenhouse effect, the surface temperature, and the temperature of the troposphere at any height, entirely on the basis of the 1st law of thermodynamics and ideal gas law, without use of radiative forcing from greenhouse gases, nor the concentrations of greenhouse gases, nor the emission/absorption spectra of greenhouse gases at any point in this derivation, demonstrating that the entire 33C greenhouse effect is dependent upon atmospheric mass/pressure/gravity, rather than radiative forcing from greenhouse gases

    Simon

    >”the estimated effective surface temperature”

    Effective temperature corresponding to the effective radiating level (ERL) of the earth is NOT at the surface of the earth. You have made a completely erroneous assumption Simon, and projected your error onto THS.

    Effective temperature
    “The effective temperature of a body such as a star or planet is the temperature of a black body that would emit the same total amount of electromagnetic radiation.[1] Effective temperature is often used as an estimate of a body’s surface temperature when the body’s emissivity curve (as a function of wavelength) is not known.”
    https://en.wikipedia.org/wiki/Effective_temperature

    Firstly, this isn’t relevant to earth anyway. The emissivity is known.

    Secondly, THS determines the “equilibrium temperature” and ERL of earth which is NOT at surface:

    Step 2: Determine the height at the center of mass of the atmosphere

    “We are determining the temperature gradient within the mass of the atmosphere using a linear function of atmospheric mass (the lapse rate), therefore the equilibrium temperature is located at the center of mass. The “effective radiating level” or ERL of planetary atmospheres is located at the approximate center of mass of the atmosphere where the temperature is equal to the equilibrium temperature with the Sun. The equilibrium temperature of Earth with the Sun is commonly assumed to be 255K or -18C as calculated here.[hotlink] As a rough approximation, this height is where the pressure is ~50% of the surface pressure. It is also located at the approximate half-point of the troposphere temperature profile set by the linear adiabatic lapse rate, since to conserve energy in the troposphere, the increase in temperature from the ERL to the surface is offset by the temperature decrease from the ERL to the tropopause.”

    Where did you get this “snippet” from, by the way?

  46. You never read what you link to Richard. Let me quote directly:
    This gives an effective temperature of 6 °C on the surface of the Earth, assuming that it perfectly absorbs all emission falling on it and has no atmosphere. The Earth has an albedo of 0.3, meaning that 30% of the solar radiation that hits the planet gets scattered back into space without absorption. The effect of albedo on temperature can be approximated by assuming that the energy absorbed is multiplied by 0.7, but that the planet still radiates as a black body (the latter by definition of effective temperature, which is what we are calculating). This approximation reduces the temperature by a factor of 0.71/4, giving 255 K (−18 °C).
    However, long-wave radiation from the surface of the earth is partially absorbed and re-radiated back down by greenhouse gases, namely water vapor, carbon dioxide and methane. Since the emissivity with greenhouse effect (weighted more in the longer wavelengths where the Earth radiates) is reduced more than the absorptivity (weighted more in the shorter wavelengths of the Sun’s radiation) is reduced, the equilibrium temperature is higher than the simple black-body calculation estimates. As a result, the Earth’s actual average surface temperature is about 288 K (15 °C), which is higher than the 255 K effective temperature, and even higher than the 279 K temperature that a black body would have.

    ASSUMING THE EARTH HAS NO ATMOSPHERE. This is NOT the Effective Temperature of the Earth.

    That is NOT the Earth Simon. The Earth has an atmosphere. THS is simply pointing out a (GHG-based) calculation of the Effective and Surface temperature of the Earth when an atmosphere is added in:

    “The equilibrium temperature of Earth with the Sun is commonly assumed to be 255K or -18C as calculated here [Hotlink to Wiki Effective Temperature of the Earth]”

    Effective Temperature: of Earth: 255 K (-18.15 °C)
    Surface Temperature of Earth: 288 K (15 °C)

    THS in his 3 step process is duplicating the Effective Radiating Level (ERL,~5km) AND the Effective Temperature (~255 K, -18.15 C) AND the Surface Temperature (14.5°C or 288°K) all WITHOUT greenhouse gases i.e. a completely different calc to the Wiki calc.

    I’m guessing, given the calculations having already been done decades ago and the results tabulated (1976 in case of US Std Atm), the calculator above is just going to “lookup tables” i.e. the tabulated 1976 Std Atm.

    The output data in the Std Atm tables did not exist before calculation i.e. the tables were NOT compiled from observations, they were confirmed by observations AFTER calculation.

    No ‘we’ don’t ‘know it’s a powerful amplifying feedback’, and the empirical evidence published by the IPCC proves that water vapour isn’t. Ever noticed how it gets a bit chillier when a cloud passes in front of the sun – is that a positive or negative feedback?

    Yes it does Dennis, The Solar Constant. This is the only system “energy” input. Geo is neglected. You are confusing how temperature in the atmosphere arises. If you compress a gas it gets hot. If you have a mass of gas pressing down it creates pressure which creates heat (simply). But there is also solar energy input. Std Atm calculates from all the physical properties what Temperature Pressure Density Speed of sound and Dynamic viscosity will be at any altitude.

    >”It just describes what it does once it’s there.”

    No it doesn’t. There are no heat transfer calcs in Std Atm except S-B and Solar Constant (W.m-2. Joules per second).

    >”Where did the energy from El Nino go? Why don’t you tell me? ”

    I will, see below. But you are of the “heat trapping greenhouse gasses trap heat in the atmosphere” faction so I’m interested in your explanation given the El Nino temperature spike is GONE from the atmosphere (and therefore the heat is GONE). I see your explanation follows.

    A twist in the “trapping” story. Apparently not “trapped” in the atmosphere after all, it was TRANSFERRED. But we can check Surface and any TRANSFER to 0-700m OHC:

    Expect similar for 2015/16 OLR data.

    An El Nino is an oceanic heat release mechanism. The heat passes through the atmosphere and is dissipated to space as OLR. No “trapping” but a TRANSFER from ocean to space.

    Schmidt, Rahmstorf, Sherwood, Foster, Mann, and the UL Met Office all claimed “most” of the El Nino heat for AGW. Schmidt even went so far as to claim ALL but 0.07C of the 2015 annual L-OTI anomaly was due to AGW, only 0.07C was natural El Nino.

    I was just highlighting the obvious, that what you claimed – “Sunlight passes through water vapour” – was not entirely correct, even as you rounded on Magoo and derided him (“That’s the key, little man”).

    I should point out too that sceptics will often take 2 positions simultaneously i.e. even they do not necessarily accept the IPCC’s TOA RF paradigm or believe the IPCC’s prognostications, it is often just as easy to operate inside their paradigm and show there’s no catastrophe looming.

    Best example of that is Climate Sensitivity (CS).

  64. I do understand the spectrum of climate debate Richard. Some people think that the equilibrium climate sensitivity (ECS) that would result from a sustained doubling of atmospheric (equivalent) CO2 concentration is low (say <1°C) whereas other believe it is high (say >2°C).
    Your "participation" in the debate is equivalent to an anti-evolutionist trying to explain how heritability works.

    Rubbish. Those in CS calculate. In order to calculate CS you are, by necessity, accepting the IPCC paradigm. A low CS position is a Lukewarm position but that does not necessarily mean the person doing the calculating and arriving at low CS actually adheres to the IPCC paradigm or is necessarily a Lukewarmer. They just decided to get stuck in and work it out for themselves within the paradigm (e.g. Nic Lewis).

    It’s just that it is easier to just operate inside the paradigm and show no catastrophe than it is to attack the paradigm t achieve the same result. This is the only reason why govt’s have been sucked in to all this. Policy institutes on the non-catastrophe side (e.g. GWPF) don’t bother fighting the paradigm, it is a waste of effort and they get no traction from the intractables. Consequently policy wonks don’t realize there is a whole other “debate” going on, one side of which certainly does not accept the IPCC’s contrived paradigm, because they are never exposed to the arguments. The Media are clueless to this too for the same reason.

    BTW, give the vindictiveness a rest Simon. It is not a persuasive argument and achieves nothing but wasted pixels.

    “Climate sensitivity is defined as the global surface warming that occurs when the concentration of carbon dioxide in the atmosphere doubles. If climate sensitivity is high, then we can expect substantial warming in the coming century as emissions continue to increase. If climate sensitivity is low, then future warming will be substantially lower, and it may be several generations before we reach what the U.N. considers a dangerous level, even with high emissions”

    “International Standard Atmosphere
    The International Standard Atmosphere (ISA) is an atmospheric model of how the pressure, temperature, density, and viscosity of the Earth’s atmosphere change over a wide range of altitudes or elevations. It has been established to provide a common reference for temperature and pressure and consists of tables of values at various altitudes, plus some formulas by which those values were derived. The International Organization for Standardization (ISO) publishes the ISA as an international standard, ISO 2533:1975.[1] Other standards organizations, such as the International Civil Aviation Organization (ICAO) and the United States Government, publish extensions or subsets of the same atmospheric model under their own standards-making authority.”

    An El Nino is an oceanic heat release mechanism. The heat passes through the atmosphere and is dissipated to space as OLR. No “trapping” but a TRANSFER from ocean to space.

  70. Dennis,

    Clouds/water vapour can still have a negative feedback, even if what you say about LWR is true. Again, the IPCC states this – don’t you agree with the IPCC on this point either dear boy?:

    ‘By reflecting solar radiation back to space (the albedo effect of clouds) and by trapping infrared radiation emitted by the surface and the lower troposphere (the greenhouse effect of clouds), clouds exert two competing effects on the Earth’s radiation budget. These two effects are usually referred to as the SW (shortwave) and LW (longwave) components of the cloud radiative forcing (CRF). The balance between these two components depends on many factors, including macrophysical and microphysical cloud properties. In the current climate, clouds exert a cooling effect on climate (the global mean CRF is negative). In response to global warming, the cooling effect of clouds on climate might be enhanced or weakened, thereby producing a radiative feedback to climate warming (Randall et al., 2006; NRC, 2003; Zhang, 2004; Stephens, 2005; Bony et al., 2006).’

    Source: https://www.ipcc.ch/publications_and_data/ar4/wg1/en/ch8s8-6-3-2.html

    Water vapour is NOT a guaranteed positive feedback, as evidenced by the empirical data in the AR5 that falsifies the hotspot. In addition, guess what happens to any heat stored in the water vapor when it condenses and rains (the IPCC reports increased precipitation) – oops, bye-bye atmosphere, hello space.

    No wonder you’re always wrong Dennis, your beliefs are based on faulty assumptions instead of reality (always a recipe for disaster dear boy). Anyway, you’re fully aware of the truth now – unless you disagree with the IPCC again that is. LOL!

    >”No discussion anywhere of energy entering or leaving the atmosphere. As I knew. That’s not the purpose. It’s for flying and engineering etc.”

    It’s an approximation with assumptions. But still verified observationally and fit for purpose. To get better resolution you need to add in satellite solar (see below).

    Those are just two small subsets you are referring to Dennis. Standard Atmosphere is an International agreement no matter for what purpose of each subset. The point is that it is not a radiative transfer model except for S-B and an “assumption” of “moderate” solar activity (US 1976 below). Right down at page 226 Figure 37 is the solar spectral assumption. Obviously there is solar change so that was never going to be valid for long but it was sufficient for the model and for the purposes.

    US Standard Atmosphere 1976
    http://ntrs.nasa.gov/archive/nasa/casi.ntrs.nasa.gov/19770009539.pdf

    At the time of the model’s development there were no satellite measurements from the Sun and Earth to determine Earth’s equilibrium temperature with the Sun but they had to start somewhere. I’ve said a number of times that Std Atm “establishes” the surface temperature. This is WRONG. The surface temperature was another “assumption” by international agreement (15.000 C). It is EVERY OTHER temperature, both above and below surface, that the Std Atm “establishes” relative to the internationally agreed 15.000 but without recourse to GHE.

    This was all from physicist Maxwell’s principles. Since the 1876 model satellite data has become available for all sorts of stuff including confirmation of the adiabatic lapse rate and solar and earth radiation. So using all the properties compiled for Std Atm it then becomes possible to derive an equation that DOES determine the surface temperature. THS explains (makes some claims I don’t agree with BTW e.g. trace gasses totally discarded, not true from what I can see although they are all but negligible, CO2 isn’t):

    Now that satellite measurements make it possible to determine the Earth’s equilibrium temperature with the Sun (Te = 255K), we can now use the greenhouse equation [hotlink – see below] to bootstrap onto this huge effort by these pioneering atmospheric scientists, and thereby calculate the average global temperature at any altitude (geopotential height) in Earth’s atmosphere all the way from the surface to the edge of space at ~100,000 km altitude, entirely without any radiative forcing from greenhouse gases whatsoever, and based only upon the mass/gravity theory of the greenhouse effect (first described by the famous physicist Maxwell in 1872), and calculated atmospheric center of mass, and without knowing the surface temperature or any other atmospheric temperature other than the constant equilibrium temperature with the Sun in advance.

    http://hockeyschtick.blogspot.co.nz/2014/12/why-us-standard-atmosphere-model.html

    So now to add in the satellite solar data and reproduce the Std Atm TROPOSPHERE including the surface temperature and with minimal “assumptions” (ε = emissivity = 1 assuming Sun and Earth are blackbodies):

    A recent series of Hockey Schtick posts

    Derivation of the entire 33°C greenhouse effect without radiative forcing from greenhouse gases
    Derivation of the effective radiating height & entire 33°C greenhouse effect without radiative forcing from greenhouse gases
    Why greenhouse gas radiative forcing doesn’t explain Earth’s energy budget

    have derived the entire ~33°C greenhouse effect as a consequence of gravitational forcing rather than radiative forcing from greenhouse gases, and entirely independent of radiative forcing from greenhouse gases. We have also determined the effective radiating height (average) or ERL in the troposphere (where T = the equilibrium temperature of Earth with the Sun), and found the ERL to be located as expected at the center of mass of the atmosphere if the ERL height and temperature are a function of mass/gravity/pressure rather than radiative forcing from greenhouse gases.

    We now join the gravitational greenhouse effect to the only source of energy that the Earth receives, the Sun, and show that solar shortwave radiative forcing plus gravitational forcing calculates the Earth’s surface temperature, ERL height and temperature, and the entire tropospheric temperature profile perfectly, without any contribution from greenhouse gas forcing, nor dependence on greenhouse gas concentrations, nor dependence upon emission/absorption spectra from greenhouse gases.

    We show that the entire 33°C greenhouse effect that raises Earth’s equilibrium temperature with the Sun of -18C or 255K up to +15C or 288K at the surface, and the temperature at any height in the atmosphere from the surface to top of the troposphere (above which the atmosphere is too thin to sustain convection), can be fully explained by the following equation, which I’m calling “the greenhouse equation”:

    http://hockeyschtick.blogspot.co.nz/2014/11/the-greenhouse-equation.html

    Where (Std Atm data, Maxwell’s principles, PLUS satellite update for solar):

    T = temperature at height (s) meters above the surface, thus at the surface s = 0
    s = height in meters above the surface to calculate the temperature T, thus at the surface s=0
    S = the solar constant = 1367 W/m2, derivation here [hotlink]
    ε = emissivity = 1 assuming Sun and Earth are blackbodies
    σ = the Stefan-Boltzmann constant = 5.6704 x 10-8 W m-2 K-4
    g = gravitational acceleration = 9.8 m/s^2
    m = average molar mass of the atmosphere = 29g/mole = 0.029kg/mole
    α = albedo = 0.3 for earth
    C = Cp = the heat capacity of the atmosphere at constant pressure, ~ 1.5077 average for Earth
    P = surface pressure in the unit atmospheres, defined as = 1 atmosphere for latitude of Paris
    R = universal gas constant = 8.3145 J/mol K
    e = the base of the natural logarithm, approximately equal to 2.71828

    Now with observed satellite solar added in there is much more detail:

    We can now use the greenhouse equation for many other purposes including determining the effect of a change in solar activity on the expected Earth surface temperature. If we increase the solar constant in the above numerical solution by 1 W/m2 from 1367 to 1368 W/m2, we find an increase in surface temperature from T=288.433K to 288.486K, an increase of 0.056C (this includes the division by 4 to convert solar insolation from a flat disk to a sphere):

    This is much finer detail than the internationally agreed 15.000 C assumption, and the Std Atm. Surface T=288.433K (15.283 C). This is done without recourse to GHE and with the addition of observed solar energy input.

    EL NIÑO’S EFFECT ON outgoing longwave radiation [2016]

    Outgoing Longwave Radiation (OLR) is the thermal radiation, or heat energy, that radiates from Earth’s surface and atmosphere and goes out to space. OLR depends on temperature, moisture, and clouds, and it’s usually largest over the subtropical desert regions and the subtropical oceans. OLR is lower in the high latitudes and in the cloudy and moist portions of the tropics. El Niño has caused a shift in the regular pattern: there is reduced OLR in the tropical eastern Pacific which causes increased convective storms and moisture, and there is a strong increase in OLR in the tropical western Pacific. This shift in the convection pattern effects on the winter storm track in California and is typical of a strong El Niño.

    There is strong latent heat and cloud transfer of energy. Tropical clouds punch up through the tropopause and radiate from the tops. That’s the increased OLR in the Western Pacific.

You would never get near finding the hiding place where the gods hide the truth. For you your friends would be calling, “cold, cold.”

    The diagrams used to illustrate the greenhouse effect show energy reflected and radiated to space. from memory, 23% of SR by cloud and the atmosphere, LR is 9% by cloud and 50% by atmosphere.

    Why do you imagine all the energy in El Nino is radiated into space? If all the LR in the atmosphere not from El Nino were radiated into space we would be at -18. Is the LR from El Nino different LR from the other LR?

    I repeat. The ISA is merely a description for users. For example, when ATC tells a pilot the QNH is 1013, he sets the altimeter at 1013 hPa, so when the pilot says he is at 3000ft the tower and other pilots know he is at 3000ft. If the pressure is high, the altimeter would read too low, so the altimeters would need to be set at say 1024 so a reading of 3000ft meant 3000ft.

    The ISA does NOT explain how energy got into the atmosphere or how it leaves. It simply defines where in the atmosphere the energy is. And presenting screeds and screeds of numbers that prove nothing more than that means you have great difficulty grasping simple concepts. But then we knew that. Already.

    Firstly, re Std Atm issues. I think I’ve come up with the differing points of view i.e. our respective arguments:

    You say GHE is a cause, not an effect (or consequence). Correct me if I misconstrue.

    I say GHE is an effect (or consequence), not a cause.

    Is this how you see it or not Dennis?

    Now on to your comment Std Atm first in this comment, El Nino next comment:

    >”I repeat. The ISA is merely a description for users.”

    I’m not disputing this Dennis. All Std Atms are a tool for users. The first aeronautical one only went to 85,000 ft, extended now. The US version was from below surface to right up past the TOA for the space race. It was however compiled by mass/gravity, physical constants and properties, not GHE. Solar input is implicit in International and US version (see below). US assumes “moderate” solar activity and a specific solar spectral profile.

    >”The ISA does NOT explain how energy got into the atmosphere or how it leaves.”

    Before the satellite era they had no observations of radiation at TOA. To get around that they simply “assumed”, by international agreement, a nominal surface temperature (15.000) that conformed to observations. This accounts for solar input i.e. solar input is implicit in the 15.000 assumption. Everyone knows atmospheric temperature has solar input. The Std Atm compilers didn’t have the solar data so they just did a workaround by accounting for solar input by the use of a nominal 15.000 starting point. Now there is satellite solar data it can be utilized as THS or anyone else wishes to. I’ve already alluded to this but didn’t explain myself, I thought it would be just stating-the-obvious. Here it is again but annotated for clarity:

    https://www.climateconversation.org.nz/2016/09/renwick-distorts-evidence/comment-page-5/#comment-1516735

    But the ‘solar constant’ is NOT “constant:

    The Inconstant Sun | Science Mission Directorate
    https://science.nasa.gov/science-news/science-at-nasa/2003/17jan_solcon/

    So temperature change at any altitude from a change in ‘solar constant’ can be determined relatively easily. Again, GHE has nothing to do with this.

    >”It simply defines where in the atmosphere the energy is.”

    This is where cause-consequence vs consequence-cause argument distinction comes in. Yes it defines where in the atmosphere the energy is but the energy input is the ‘solar constant’ implicit in the nominal Std Atm 15.000 and explicit in the ERL-Effective Temperature obtained by satellite observation of the present ‘solar constant’ in the satellite era. The atm properties and major constituents MUST be determined to carry out he gravity/mass calculations in the Std Atm. This has nothing to do with GHE and GHE is not part of the process. You can fact-check this for yourself in the US Standard Atmosphere 1976 linked upthread

    Radiative transfer comes into play consequently as does Latent and Sensible heat. This is the hugely simplified earth’s energy budget showing energy flows. Obviously the flows are not as per that simplified budget diagram at every altitude level. The flows are just from “effective” levels. And after that there’s weather, wind, Hadley cells, and what have you.

    Once the satellite obtained ‘solar constant’ was available it was just a matter of reproducing and refining the Std Atm except the surface temperature can be calculated rather than nominally assumed. Again this has nothing whatsoever to do with GHE and the 33C difference is fully explained at ERL, not surface.

    GHE is a consequence, not a cause.

    I don’t “imagine” it Dennis, I’ve gone through a process of observational observation. Plus I know the Second Law of Thermodynamics, or, as Habibullo Abdussamatov leader of the Russian part of the International Space Station and Pulkovo Observatory pus it – “Heat rises up, not down”.

    >”If all the LR in the atmosphere not from El Nino were radiated into space we would be at -18″

    The earth is being constantly replenished by SW so is constantly radiating LW irrespective of El Ninos. Yours is Spencer reasoning Dennis. Isolating one factor and ignoring all others.

    >”Is the LR from El Nino different LR from the other LR?”

    There’s more of it for a start. This is why El Nino shows up as an OLR anomaly i.e. a variation from normal.

    You have exactly the same problem as the IPCC don’t you Dennis? Your theory demands that the El Nino heat was “trapped” by the troposphere and retained in the system so you’re desperately trying to sink it SOMEWHERE. Except the IPCC sink most of theirs in space:

    The heat only manifests in the material Dennis. There is plenty of radiation passing through space but no heat. You have to place a space vehicle in the path of the radiation to get heat. So radiators direct radiation down (no heat). The radiation strikes material (people). The radiative energy is converted to heat energy. The heat rises. It is cooler at floor level than at ceiling level.

  81. Dennis,

    Now, now dear boy, there’s no need to be rude, it’s not my fault you hold an untenable position that is contradicted by a 100% consensus of the empirical evidence.

    ‘All the greenhouses gases in total, that is the greenhouse effect, generate a positive feedback.’

    And where is the evidence that water vapour is generating a positive feedback in the atmosphere? AHHH!, you need empirical evidence to prove that don’t you? Shame the empirical evidence in the AR5 shows there isn’t a positive feedback from water vapour due to the upper troposphere not warming as predicted (remember, this is the IPCC’s definition & data, not mine).

    Now, since 100% of the empirical temperature data in the IPCC’s AR5 shows water vapour is not providing a positive feedback, & the IPCC dictates that 50% of the warming should be due to water vapour, how is CO2 a problem? Psst, I’ll give you a clue – it’s not.

    Sorry Dennis, but your sandwich board, end of the world street corner act is just another village idiot choking on a chicken bone, but knock yourself out if you like – I’m sure lots of people who think they’re Napoleon or Jesus Christ live a full and rewarding life in their own deluded way.

So where is this great consensus agreement between ‘millions of informed scientists’ & ‘every scientific institute and society on the plane’ confirming positive feedback from water vapour, or is it just another one of your delusions?

    Perhaps you mean many scientists believe CO2 warms the atmosphere, is that what you mean? Even I agree with that, it’s just that CO2 is too weak to cause much of a problem by itself without positive feedback from water vapour, & the empirical evidence published by ‘climate scientists’ & the IPCC disproves positive feedback from water vapour according to their own definition dear boy. Oops!!

    Le’s just analyse your vastly superior intellect & logical brilliance in action here Dennis:

    1/ You believe in positive feedback from water vapour by ignoring the empirical data from more than 30,000,000 radiosondes and 2 satellites published by the IPCC in their AR5 report. Do you disagree with these ‘climate scientists’ & their data Dennis, is their empirical evidence incorrect?

    2/ Or maybe you disagree with the IPCC’s statement that the upper troposphere should warm faster than the lower troposphere as evidence of positive feedback from water vapour – perhaps you disagree with those ‘climate scientists’ Dennis, is that it?

    3/ So which is it Dennis, is the IPCC’s empirical data wrong, or is it their definition of evidence of positive feedback from water vapour that is incorrect? Take your pick dear boy, but you can’t have it both ways.

    Here’s an interesting review paper… just appeared in the latest Nature Climate Change..entitled “Assessing recent trends in high-latitude Southern Hemisphere surface climate”
    http://www.nature.com/nclimate/journal/v6/n10/full/nclimate3103.html

    Multiple authors, including James A. Renwick.

    From the abstract:
    Climate model simulations that include anthropogenic forcing are not compatible with observed trends.
    and
    Most observed trends are not unusual when compared with Antarctic paleoclimate records of the past 2 centuries.

    Discussion
    Climate change and variability over the high latitudes of the SH are
    characterized by strong regional and seasonal contrasts for all the
    variables investigated here. This is valid at interannual to decadal
    timescales, as illustrated in instrumental observations, as well as
    on longer timescales, as indicated in proxy-based reconstructions.

    The most unequivocal large-scale change over recent decades is
    the increase of the SAM index19 and the freshening and subsurface
    warming of the ocean23,24,41. Regionally, a large warming has been
    observed over the Antarctic Peninsula and West Antarctic regions
    across the past 50  years. SIE has decreased in the Amundsen–
    Bellingshausen Seas while it has increased in the Ross Sea sector
    since 1979.

    The large multi-decadal variations seen in high-resolution
    proxy-based reconstructions of temperature and SIE also have clear
    regional contrasts. Some estimates suggest common signals over
    the whole Southern Ocean, such as the decrease of the ice extent
    between the 1950s and the late 1970s deduced from whaling records
    (for example refs 86–88), but this remains to be confirmed by the
    analysis of additional observations. The longer records independently
    support the conclusion that most of the recent changes for
    any single variable largely result from natural variability and are not
    unprecedented over the past two centuries. This is consistent with
    results from state-of-the-art climate models showing that, except for
    the SAM index, most recent changes remain in the range of largescale
    simulated internal variability. When analysing specifically the
    1979–2014 period, including forced changes and internal variability,
    models struggle to track the observed trends in SST, SAT and
    sea-ice cover. This suggests either that a singular event associated
    with internal variability has been able to overwhelm the forced
    response in observations, or that CMIP5 models overestimate the
    forced response (potentially partly because of key processes missing
    in the models), or a combination of both.
    Recent observations and process understanding of the atmosphere,
    sea ice, ocean and ice sheets suggest strong coupling, which
    means that investigations need to encompass and understand the
    dynamics of the whole climate system. Statistics independently
    applied to a few large-scale metrics may not allow a robust comparison
    between observed and simulated trends. Regional and
    seasonal complexity89 as well as physical relationships between different
    climate variables must be taken into account to evaluate the
    overall consistency of observed and modelled time-evolving climate
    states, and to identify caveats. We advocate process-oriented studies
    in which the primary mechanisms behind modelled behaviour are
    identified and their plausibility evaluated against available observations
    and theory.

  90. Quote of the day:

    There’s no point trying to fight climate change – we’ll all be dead in the next decade and there’s nothing we can do to stop it, a visiting scientist claims.

    Guy McPherson, a biology professor at the University of Arizona, says the human destruction of our own habitat is leading towards the world’s sixth mass extinction.

    Instead of fighting, he says we should just embrace it and live life while we can.

    “It’s locked down, it’s been locked in for a long time – we’re in the midst of our sixth mass extinction,” he told Paul Henry on Thursday.

    But Professor James Renwick, a climate scientist at Victoria University, says people should not use his words more as an excuse to give up.

    Obviously James Renwick is in denial
