‘Stack Theory’ Mathematics Paper Discredits Greenhouse Gas Climate Alarm
Written by Hans Schreuder
In a detailed new mathematical study the actual atmospheric effect of infrared-active gases are examined for climatic impact. Principia Scientific International (PSI) researcher, Jef Reynen explores the so-called ‘stack model’ of earth’s climate and finds that it is possible to more accurately model climate without factoring in any ‘greenhouse gas effect.’
His new paper, Lessons from a chicken wire stack on the Moon, re-examines a concept first addressed at PSI three years ago. Back then Reynen considered a finite difference one-stream-heat-flow formulation. More recently, he has employed the more transparent finite element method (FEM).
Due to the recurrent failures of computer simulations to model climate, Reynen’s more pragmatic approach employs the concept of a stack of chicken wire in a vacuum environment (that is, where convection is not possible) e.g. on the Moon. In a vacuum, the stack has a temperature and heat flux completely defined by the process of radiation, without convection. Conventional computer climate modeling disavows itself of the dominance of convection (e.g. wind impacts) and applies a far more radiation-obsessed approach; whereas in the reality of planet Earth, it is nearly the other way around. This, says Reynen, has been climate science’s great error.
In the Reynen model, a stack of grids represents the IR-active gases. Reynen refuses to talk about“greenhouse gases and their effect” because that’s a misnomer according to him and other PSI scientists. What can be described by this innovative new model is an explanation of the atmospheric effect that keeps our planet at a pleasant temperature – strictly in accordance with sound thermodynamic principles. This fits with original concepts from the earlier days of climate research, and the potential temperature already defined by Poisson and more recently by adiabatic lapse rates. That approach was abandoned by conventional climate science in a “wrong turn” made in the 1980’s in preference for the now increasingly discredited carbon dioxide-driven ‘greenhouse gas’ theory.
As Reynen and PSI colleagues insist, greenhouses in nurseries are warmer because the glass roof hinders the convective cooling! There is no enhanced radiative effect achievable in this glass house scenario and the notion of CO2 radiative warming is bogus.
As is shown by the stack model, the evacuation of heat from the planet is rather by convection from the surface of the planet to the upper layers and from thereon by radiation to outer space – thanks to the IR-active gasses with three or more atoms per molecule, like H20 vapor, CO2, CH4, O3, N20…
The stack in a vacuum absorbs nearly the full longwave (LW) radiation from the surface and in steady state emits it immediately. The net result is a temperature that is tens of degrees lower than the measured temperature distribution in an atmosphere of 99% O2 and N2 – on planet Earth. That temperature distribution is described with the environmental lapse rate ELR = – 6.5 K/km being between the dry adiabatic lapse rate DALR = -10 K/km and the saturated adiabatic lapse rate SALR = -5 K/km. These lapse rates follow from sound thermodynamic principles of adiabatic expansion, with or without moisture and the environmental lapse rate in between, from measurements.
What Reynen shows is that when the stack is ‘put’ in earth’s atmosphere, the IR-active trace gases do not cool to what is observed in a vacuum; the trace gases remain at the temperature of the atmosphere. No detailed heat transfer calculations are necessary; the heat capacity of the trace gases is negligibly small compared to that of the bulk of the 99% O2 and N2 of the atmosphere.
The IR-active trace gasses near the surface absorb little heat from the surface since they are at about the same temperature!
The evacuation of heat from the planet is carried out by convection from the surface to higher layers and from there on by radiation from IR-active trace gasses to outer-space.
The validation of the stack model i.e. the question whether a stack of chicken wire can represent the traces of IR-active gases, was carried out in a parameter study by varying the distribution of the thickness of the wires such that results of the analyses coincided with K&T type of studies (Kiehl, J. T. and Trenberth, K. E., 1997), based on the two-stream formulation of Schwarzschild, however ignoring the back-radiation and thereby the non-physical huge atmospheric absorption.
In this fascinating update, Reynen has compared the stack results with recent results of Ferenc Miskolczi, based on the two-stream Schwarzschild procedure, but ignoring the back-radiation and the huge atmospheric absorption. The findings are another mathematical proof against the existence of any supposed ‘greenhouse gas effect’ in our climate system.
