Alternative Greenhouse Gas Theory

The 33°C Greenhouse “Envelope”

This subject was previously included in the previous post: “Errors in CO² Emissions?”  It attracted sufficient interest to require that it should have it’s own post.

So … there’s all this talk about CO² emissions being at the heart of the problem and causing so much angst between alarmists and sceptics, but what if CO² isn’t even relevant?

Scientists mostly agree that without GHG the global average temperature of the Earth would be about -19°C and that a natural 33°C “envelope” of warming GHG brings it up to around 14°C or so.  What they don’t agree on is the cause of this natural warming. There are at least two separate theories. One that discusses GHG radiation and the other a gravito-thermal greenhouse effect or to put it more simply – greenhouse gases vs natural processes.

The 33°C Arrhenius Radiative Greenhouse Effect
(Greenhouse Gases)

Don’t let the title put you off.  It just means the greenhouse theory used by the IPCC and in their computer climate models . It’s probable that most scientists agree that elements of different radiative gases including CO² are trapped in the atmosphere and re-radiate heat back to Earth thus causing a cycle of continual warming of the planet.

An example of the 33°C Arrhenius Radiative Greenhouse Effect theory. NB: Natural “feedback” cooling effects not shown here.

But it’s important to understand that the 33°C envelope is not just all warming as is commonly expressed as shown in the example.  It is really the end result of roughly 50/50 warming AND cooling effects i.e. a combination of both natural climate forcing (heating) and feedback (cooling) systems. This has been known for a long time and supported for example in scientific papers by Messrs Manabe and Strickler in 1964 and Dick Lindzen’s paper in 1990.

In any case,  if the Arrhenius theory is correct, then mankind obviously must be responsible to some extent – although arguably not to the levels we are being led to believe. That viewpoint also applies to the possibly exaggerated future consequences of increased global warming.

But given that the planet is subject to both warming and cooling influences, shouldn’t the warming of less than 1°C over the last 150 years or so alleged to have been caused by mankind, also be reduced to about 0.05°C?

The 33°C Gravito-Thermal Greenhouse Effect
(Natural Processes)

Other scientists follow the Gravito-Thermal theory which began in 1738 when Daniel Bernoulli learned how to understand air pressure at a molecular level. Some problems were further explained in the 1850s by Maxwell  who found it wasn’t necessary to track every molecule but just the distribution of them e.g. how the microscopic connected to the macroscopic. Albert Einstein did some work on related Kinetic Theory in 1907. In 1976 the final version of a 241 page supporting document the US Standard Atmosphere was published.

One of the adherents to the Gravito-Thermal theory was a leading Physicist Richard Feynmann (decd 1988). He said the greenhouse effect that warms the Earth is due solely to the effects of gravity, atmospheric mass, pressure, density, and heat capacities, and not due to any “trapped” radiating elements of greenhouse gases. And not just the 33°C “envelope” but constantly.

Was he a crackpot?  Not likely. He was a Nobel  Prize winner in Physics in 1965 along with several other awards. He and allegedly hundreds of rocket and atmospheric scientists, physicists and aeronautical engineers were involved in formulating the US Standard Atmosphere. It provides the means to determine the temperature, pressure and density at any altitude. It’s used for example in aviation applications and in application of this theory.

Nowadays, the “33°C Maxwell/Clausius/Carnot/Feynman Gravito-Thermal Radiation Effect” aka gravitational forcing theory maintains that the generally accepted greenhouse radiative gases version confuses “cause with effect” in the Earth’s warming processes.  In other words they say the gravito-thermal processes comes before any radiation from greenhouse gases.

The world’s scientists don’t seem to be even able to agree on how the Earth is warmed naturally let alone that mankind’s activities are responsible for additional warming.  Only one 33°C “envelope” warming theory can be correct.   Surely it’s impossible to determine human effects if you don’t know the natural patterns or causes.  And we apparently don’t …
