Heat Flow
The climate science greenhouse effect is a simulacrum. It is not science, nor is everything that is based on it science. All of climate alarm is a simulacrum, a fraud, and most of what could have been real climate science has been infected and ruined by it. It uses the words of science to give itself the appearance of science, but it does not actually contain the essence of science, i.e. the method or wisdom or rationality of science. See the last post for more detail on this. What it is, is an attack on human existence.
Let’s cover some basics about calculating the temperature that heating from sunlight is able to generate on a surface absorbing solar energy.
The temperature T induced by sunlight on a cooler surface when in thermal equilibrium is given by
F = ε*σ*T4
where F is the absorbed (and then re-emitted when in equilibrium) flux. The absorbed flux is the solar insolation, ‘I’, multiplied by the absorptivity, and absorptivity is 1 minus the albedo ‘α’. So then
I*(1-α) = ε*σ*T4
and you can rearrange for T to get the temperature of the surface absorbing the insolation:
T = (I*(1-α)/ε/σ)1/4
This equation predicts surface temperatures exposed to sunlight very accurately, as shown in real greenhouses, black asphalt, beach sand, car interiors, spacecraft, etc.
Now, the equation
Q = A*σ*(Th4 – Tc4)
is for heat flow. (‘A’ is the area here so that the units of heat are properly in Joules.) Q is just the portion of the energy which is flowing as heat. This is a different thing than what we just looked at. Q is not the value of absorbed solar insolation, I*(1-a). Q is not the solar insolation energy. If it was, then you would have
I*(1-α) = A*σ*(Th4 – Tc4)
but that equation is nonsensical, because the terms don’t make sense given the preexisting context of solar insolation absorbed into a surface. In the first place, the units on the left and right hand sides don’t even match! And then, what is Th?
