Heinlein Explains Global Warming:   “It is a truism that almost any sect, cult, or religion will legislate its creed into law if it acquires the political power to do so.”


    It is obvious to any physicist that the greenhouse conjecture is false, because the direct solar radiation reaching the surface is less than a third of what would be required to explain observed surface temperatures.

    James Hansen noted this apparent discrepancy and, not realizing that the rest of the required thermal energy is in fact supplied during the day by non-radiative processes, he wrongly assumed that radiation from the cold atmosphere could be added to solar radiation and the total used in Stefan-Boltzmann calculations. But even the net of 390W/m^2 which included the back radiation would not be enough because it is variable flux and can thus only achieve a mean temperature much closer to freezing point. He really needed over 450W/m^2 but glossed over that fact and “taught” the world of climatology the totally incorrect physics based on compounding the radiation from two effectively sub-zero sources and assuming that the sum “explained” observations.

    Now, most of the atmospheric radiation comes from the most prolific “greenhouse” gas, water vapor which is claimed to cause warming, though evidence suggests the opposite. So where did it all go so wrong? Hansen incorrectly assumed that, without IR-active greenhouse gases, the temperatures in the troposphere would be isothermal. That is not what the Second Law of Thermodynamics tells us, because it says entropy will be a maximum, not temperatures equal. Every vortex cooling tube in the world demonstrates how a force field (like gravity or centrifugal force) sets up a radial temperature gradient as that force acts on molecules in flight between collisions. The “lapse rate” (climatology speak for temperature gradient) is not due to imaginary “parcels” of air rising, expanding and cooling, because there is nothing to hold any such parcels together as the molecules move randomly between collisions at speeds of about 1,800 Km/hour.

    This temperature gradient evolves at the molecular level in accord with the process of maximum entropy production, and that state of maximum entropy is reached when there are no remaining unbalanced energy potentials. That means that the sum of mean molecular gravitational potential energy and kinetic energy is homogeneous, and so there is a temperature gradient.

    Once we understand that the temperature gradient is what physicists call the state of thermodynamic equilibrium, then everything falls into place. We can deduce quite simply that new solar energy absorbed in the stratosphere and upper atmosphere each morning will disturb the equilibrium and it can only be restored by downward non-radiative heat transfers, these being the real source of the missing energy Hansen tried to explain with back radiation.

    So, in fact, temperatures in a planetary system build up from anchoring layers in the upper troposphere and above, all the way to the core, because the temperature gradient, forming at the molecular level, can be calculated and shown to occur in solids, liquids and gases. It forms by a slow process which can be over-ridden, and is, in the oceans and the stratosphere, but, in general, it dominates. It is observed in all planetary tropospheres, and so the probability of this “heat creep” hypothesis being wrong is millions to one against.
