We’ve been having a good knockabout on twitter with Patrick Moore concerning Ned and Karl’s Pressure-Insolation theory; their discovery that a simple formula using surface pressure and solar distance will accurately give you the surface temperature on vastly different planets and moons throughout the solar system.
Patrick is a great guy, and a good sport, and has been mostly putting up with Ned’s jibes and arguing his corner. I thought it might help others to understand Ned and Karl’s ideas if we look at a few of the objections Patrick raises and our answers to them.
Insult cheerfully censored. Steady Neddy!
What I mean by ‘heavyweights’ is that Insolation (solar radiation) is the primary driver of Earth’s climate. Without it, Earth would be a cold dead particle in the universe. Oxygen, Nitrogen and other trace gases would be frozen liquid on its surface. The Sun’s energy pouring down vapourises those elements into gases and inflates the atmosphere.
They would then float off into space if it weren’t for the Earth’s gravity. Atmospheric pressure is caused by gravity acting on the mass of the atmosphere. The force of gravity squishes the atmosphere against the barrier of Earth’s surface. The air at the bottom next to the surface gets squished the most, as it has all of the mass of the rest of the atmosphere pushing down on it from above. Halfway up the atmosphere, there’s only half of the atmosphere pressing on it from above. This arrangement means that the atmospheric pressure has a gradient from low pressure at the top, to high pressure at the bottom. That’s why climbers near the top of mount Everest need oxygen bottles; the air is too thin to get enough into their lungs fast enough for exertion. Pressure affects the density of the air. Lower pressure – less molecules per litre.
All the other atmospheric phenomena climate scientists are interested in are operating within this pressure-insolation envelope. For example the amount of cloud reflecting sunlight back to space before it can warm the surface is affected by pressure.. Clouds form when the air carrying water vapour has risen, expanded in the lower pressure environment at higher altitude, and cooled due to that expansion. The cooling makes the water vapour condense and form the clouds.
Climatologists and atmospheric physicists are going to need to escape from the morass of detail of what goes on in the atmosphere and lift their eyes to the heavens for inspiration. Venus and Mars are telling us something important. The cloud albedo is the third most important climate variable after solar radiation and gravity induced atmospheric pressure. And cloud albedo amount depends almost entirely on those two primary variables.
Ned and Karl are having trouble getting a fair hearing for their theory because the radiative greenhouse concepts are so firmly embedded in the education and research effort of warmist and sceptic climate scientists alike. We need to help cut through the confusion and help them get influential people like Patrick to understand their ideas properly.
