Climate textbook explains why man-made CO2 does not control atmospheric CO2
Climate scientist Dr. Murry Salby, professor and Climate Chair at Macquarie University, Australia explains in the 2012 edition of his textbook, Physics of the Atmosphere and Climate, why changes in global temperature control CO2 levels, not man-made CO2. The text corroborates the works of Humlum et al, Frölicher et al, and Francey et al demonstrating that man-made CO2 is not the driver of atmospheric CO2 or global temperatures.

ReplyDeleteWithout gravity acting to restore the thermodynamic equilibrium which is stipulated in the Second Law of Thermodynamics (which says: "An isolated system, if not already in its state of thermodynamic equilibrium, spontaneously evolves towards it. Thermodynamic equilibrium has the greatest entropy amongst the states accessible to the system") and thus, as a direct corollary of that Law, supporting (at the molecular level) an autonomous thermal gradient, then ...
(1) The temperature at the base of the troposphere on Uranus would be nowhere near as hot as 320K because virtually no direct Solar radiation gets down there, and there is no surface at that altitude. The planet's radiating temperature is under 60K because it receives less than 3W/m^2.
(2) The temperature of the Venus surface would be nowhere near as hot as 730K (even at the poles) because it receives only about 10% as much direct Solar radiation at its surface as does Earth at its surface.
(3) Jupiter would be nowhere near as hot, even in its core, which receives extra kinetic energy which was converted by gravity from gravitational potentential energy due to the continual collapsing of this gaseous planet. This is why Jupiter emits more radiation than it receives.
(4) The core of our Moon would be nowhere near as hot as it is thought to be, probably over 1000K.
(5) Earth's surface would indeed be perhaps 20 to 40 degrees colder, and the core, mantle and crust nowhere near as hot, maybe no molten material at all.
Think about it! If you're not sure why, it's explained in Sections 4 to 9 and Section 15 here.
