‘Climate ScienceTM’ (represented and promoted by the IPCC) has so corrupted ordinary people’s way of thinking, that in order to demonstrate why there is no ‘atmospheric radiative greenhouse effect’ (rGHE), you have to start all the way from scratch. You have to step completely outside the framework of their concocted ‘mental model’ within which they shape their arguments.
‘Climate ScienceTM’ is afflicted with a dual case of monomania, two major fixations that they cannot and will not drop under any circumstances.
The first one is a complete linear trend line mania. They are unable to look at a data time series and not mentally project one onto it. The data – and especially the variation in it – basically doesn’t matter. Only the straight trend line plastered across it, from the one end to the other, does.
The second one, of direct relevance to this post, is their peculiar obsession with radiative flux intensities and their perceived direct correlation with the surface temperature of objects, expressed by the purely radiative Stefan-Boltzmann relationship. They clearly misinterpret and hence stretch the applicability of this law in the real world far beyond its actual justified range of operation, but absolutely refuse to recognise it. They worship (and use) it as sanctified truth.
Basically, they see the world in terms of radiation first and last. Everything in their world is in the end determined and controlled by thermal radiation. When it comes down to it, according to the warmists, you can simply scrape away everything else and just look at instantaneous radiative emission fluxes and directly know surface temperatures. As if we all lived in Max Planck’s conceptually pure radiative universe.
‘Climate ScienceTM’ thinks (or promotes the idea) that the temperature of any object – even real-world objects on Earth – is determined strictly by its radiative energy output (its emission flux), likewise that this final temperature is known and fixed even from the onset of heating, simply by the instantaneous intensity of its radiative energy input (the absorbed flux) minus convective loss (!).
In other words, if you only know the total (added) intensity of the instantaneous radiative energy flux input to the surface of an object and you are at the same time able to determine its energy loss through convection per unit of time, you will be able to tell its final temperature, no actual thermo-measurement required. Or, turn it around, if you know the temperature of an object, you instantly know the intensity of its radiative energy output, regardless of any simultaneous convective loss of energy.
(Well, you also need to know its surface emissivity/absorptivity, but according to ‘Climate ScienceTM’ most relevant real-world materials (like soil, rock, water, vegetation) possess emissivities close to unity anyway, and so can be approximated as (convecting) black bodies …!) Continue reading
