Global Warming Laws Of Thermodynamics

  1. An ice cube can’t melt if the temperature in the room is steady or declining.
  2. When glacial ice melts, the water often just disappears.
  3. An atmosphere with 95% CO2 can be as hot as Venus or as cold as Mars. CO2 controls the temperature, but is very fickle.

  1. 4) Tropical islands rebound from glacial retreat.
    5) A set of measurements that are accurate to ±1% can be averaged to produce a measurement that is within ±0.001%

    • DirkH says:

      5) is actually possible when you have a nonsystematic error; for instance an error with Gaussian distribution or pure noise. The problem is that in the real world it’s not easy to exclude systematic errors. Precision rises with the square root of the number of measurements in the cases where it’s possible if i recall correctly.

      • Grumpy Grampy ;) says:

        Every thing that does not fit the desired pattern is considered noise in climatology!

      • Baa Humbug says:

        6) Real world measurements can be adjusted at will
        7) If the real world measurements don’t match computer modelling, see 6

      • Scott says:

        Dead on Dirk, as long as there’s no systematic error (accuracy vs precision), the uncertainty will usually improve with the sqrt(N).

        However, it also depends on the frequency of the noise relative to the signal you’re trying to measure too. I leared that the hard way once….


  2. 6. Heisenberg’s Uncertainty Principle (climate) states that a given amount of heat can produce either warming or cooling, depending on the argument being discussed.

    7. Latent heat doesn’t apply to ice. Ice will melt as soon as the surrounding temperature rises above zero Celsius. This also means that melting ice will not cool its surroundings.

    8. Increased water vapour in the atmosphere won’t produce more clouds. The “hot spot” prevents that occurring.

    9. Heat can “go missing” for decades, popping out when least expected, usually when the air conditioner has just packed in, or at any time if you’re a European.

  3. Sundance says:

    6) The most heat will be found where the fewest thermometers are.

  4. Latitude says:

    global warming makes tropical islands flip over…………..

  5. Scott says:


    You’ve used the 95% argument before and you know why it’s not valid. What’s important is the absolute concentration of the GHG (moles/volume) and not its concentration relative to the total pressure (though total pressure itself is also important).


    • The density of CO2 molecules in Mars atmosphere is an order of magnitude larger than on Earth, so the argument works perfectly, thank you.

      • Scott says:

        I had the numbers from a spreadsheet from a previous time this came up.

        The planets have approximately these densities of CO2:
        Venus = 1.408 mol/m3
        Earth = 0.000017 mol/m3
        Mars = 0.000346 mol/m3

        Mars has ~21x higher density of CO2 than Earth, and Venus has ~4070x higher density than Mars.

        So yes, Mars>Earth by more than an order of magnitude.
        And Venus>Mars by 3.6 orders of magnitude.

        And that’s before any pressure broadening effects. Steve – you have many valid points on this site…but this is not one of them. You can argue the GHG effect if you want…but don’t make it a straw man about equal 95% numbers.


      • Scott, darling, the so called “greenhouse effect” is derived purely by the occlusion of certain wavelengths of radiation supposedly by Carbon diOxide. The maths is left as an exercise for the apologist.

  6. 11. Steig’s principal states that temperature rises with distance from a warm object, e.g Antarctic Peninsula. This is the inverse of Hansen’s principle which states that temperature rises when approaching a cold object. Hansen’s principle is to be preferred as it requires no data for proof.

  7. NikFromNYC says:

    12) You can fool all of the people all of the time.

  8. Al Gored says:

    e = mc2

    where e = exaggeration, m = model, c = consensus

    Unlike that quaint old-fashioned version of this equation, the c varies. A 97% consensus (75 of 77) and virtually any m can produce fantastically ultra-robust unprecedented catastrophic slamdunk results that only reptile-brained planet haters can deny.

  9. Nobama says:

    CO2 will make the earth warmer, except when it’s colder, or stays the same, unless we say so.
