Control the sun

  1. The article referred to by Joseph Postma is the kind of flat earth mis-applied physics nonsense that has no function other than discredit anybody skeptical to the political global warming story.

    One example on how this nonsense has been received by real scientists in this field:

    “Exercises such as Postma that use (or misuse) the planetary energy balance equation cannot disprove the existence of the Earth’s greenhouse effect. If you want to disprove the existence of the greenhouse effect, you need some sort of alternative explanation for a whole lot of fundamental physics that explains the infrared emission spectra as measured at the Earth’s surface and high above the emitting portion of the atmosphere”

    Judith Curry


    • I will note 2 things in that regard, 1. The earth is not getting warmer, i.e that fact supports Postmas view and article.
      2. You do not need to make up new math to disregard the falsified human caused global warming/ human caused climate change (what is the right terminology this week?)

      I also need to mention, you quoted Judit Curry, please post the documentation where she wrote that ..

      ” 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.

      The greenhouse gas water vapor does have a very large negative-feedback cooling effect on the surface and atmospheric temperature by reducing the lapse rate by half from the 10C/km dry rate to the 5C/km wet rate. Increased water vapor increases the heat capacity of the atmosphere Cp, which is inversely related to temperature by the lapse rate equation above:

      dT/dh = -g/Cp

      Plugging these lapse rates into our formula for Ts above:

      Ts = -18 – (10 × (0 – 5)) = 32C using dry adiabatic lapse rate

      Ts = -18 – (5 × (0 – 5)) = 7C using wet adiabatic lapse rate [fully saturated]

      showing a cooling effect of up to 25C just from changes in the lapse rate from water vapor. Water vapor also cools the planet via evaporation and clouds, and which is confirmed by observations. Water vapor is thus proven by observations and theory to be a strong negative-feedback cooling agent, not a positive-feedback warming agent as assumed by the overheated climate models to amplify warming projections by a factor of 3-5 times.

      What about CO2? At only 0.04% of the atmosphere, CO2 contributes negligibly to atmospheric mass and only slightly increases the heat capacity Cp of the atmosphere, which as we have shown above, is inversely related to temperature. CO2 would thus act as a cooling agent by slightly increasing troposphere heat capacity. Increased CO2 also increases the radiative surface area of the atmosphere to enhance outgoing radiation to space, analogous to putting a larger heat sink on your microprocessor which increases radiative surface area and convection to cause cooling.

      It is well-known that CO2 and ozone are the primary cooling agents of the stratosphere up to the thermosphere, but even the warmist proponents are unable to agree on a coherent explanation why CO2 would assume the opposite role of a warming agent in the troposphere. As the mass/gravity/pressure greenhouse theory shows, and just like water vapor, CO2 also acts to cool the troposphere, and the rest of the atmosphere by increasing radiative surface loss and outgoing radiation to space.

      Millions of weather balloon observations confirm that there is no greenhouse gas-induced “hot spot” in the mid-upper troposphere, which is the alleged “fingerprint of AGW.” The 2nd law of thermodynamics principle of maximum entropy production also explains why such a “hot spot” will not form. However, observations do show a cooling of the stratosphere over the satellite era, which would be consistent with increased CO2 increasing outgoing radiation to space. Observations also show an increase of outgoing longwave radiation to space over the past 62 years, which is entirely consistent with increased outgoing radiation from greenhouse gases and a decrease of “heat trapping”, the opposite of AGW theory.

      In essence, the radiative theory of the greenhouse effect confuses cause and effect. As we have shown, temperature is a function of pressure, and absorption/emission of IR from greenhouse gases is a function of temperature. The radiative theory tries to turn that around to claim IR emission from greenhouse gases controls the temperature and thus pressure and heat capacity of the atmosphere, which is absurd and clearly disproven by basic thermodynamics and observations. The radiative greenhouse theory also makes the absurd assumption a cold body can make a hot body hotter, disproven by Pictet’s experiment 214 years ago, the 1st and 2nd laws of thermodynamics, the principle of maximum entropy production, Planck’s law, the Pauli exclusion principle, and quantum mechanics. There is one and only one greenhouse effect theory compatible with all of these basic physical laws and millions of observations. Can you guess which one it is?

      Update: The atmospheric center of mass assumption in step 2 above also appears to be applicable to Titan, the closest Earth analog with a thick atmosphere in our solar system. For Titan, the surface temperature is 94K, equilibrium temperature with the Sun is 82K, and surface pressure is 1.47 bar.

      Thus, the center of mass of the atmosphere is located at ~1.47/2 = ~0.74 bar, which observations show is where Titan’s atmospheric temperature is ~82K, the same as the equilibrium temperature with the Sun.”
