what errors were his? And, what did he misinterpret? he merely copy and pasted the material from the university.well factually speaking, SSDD was using the information to see what you all thought about what old socks posted. It was a trap post.the source of the original post for your guidance.Look at the damned graph....or any graph of the greenhouse effect...see the incoming solar radiation..that's one of your radiators...239.7wm^2....please tell me that you are aware that 239.7 wm^2 equates to a radiating temperature of -18 degrees....you are aware of that...aren't you?....
Now see the energy radiating up from the surface?....239.7 from the sun...and 239.7 from the atmosphere....two radiators...both radiating ...239.7wm^2 equates to a radiating temperature of -18 degrees....so they combine the radiation from these two radiators which are radiating at -18 degrees and suddenly you have a temperature of 29.85 degrees...
I am starting to think that you can't read a simple equation either...and I am betting that since you seem to realize that the sun is hot...that the climate science claim of the surface of the earth radiating at -18 degrees is just one more bit of bullshit upon which the greenhouse effect is based...
Questions.....RE: The Greenhouse Effect
The sun and the atmosphere, both radiating at -18C. DERP!
And I thought you were smart enough to know what you were talking about.
Energy flux absorbed by the Earth = Radiation emitted by the Earth
239.7 W/m2 = constant x T4
To solve this equation, all we need to do is divide the emitted radiation (239.7 watts per square meter) by the constant (5.67 x 10-8) and take the fourth root of the result. Dividing we obtain 42.3 x 10-8. We'll take the fourth root on a calculator, but to check it's a good idea to estimate the result by taking the square root of 50, which should be just about 7 and taking the square root of 7 which should be around 2.5. The fourth root of 10 to the eighth power is 100. Hence, the answer should be a number around 2.5 x 100 or 250. The calculated result is 255. Remember that all results obtained from the Stefan_Boltzmann Law and other radiation laws are expressed in degrees Kelvin, so this is 255 K (-18 °C, 0 °F):
T = 255 K
The figure below illustrates how we derived this energy balance.

This effective temperature of 255 K is the temperature the Earth's Surface would have if it didn't have an atmosphere. It would be awfully cold! In reality, the Earth's surface temperature is closer to 288 K (15 °C, 59 °F). This difference of 33 K is the magnitude of the greenhouse effect. Before we go into more details about what this greenhouse effect is, let's look at Venus and Mars, our closest neighbours and calculate their effective temperatures.

There you go, anyone can go to the site and see what it says.
Thanks!
Now where did that source, or Old Rocks, say that the Sun is radiating at -18C?
Or was that something SSDD said?
It was a trap post.
Yes. SSDD misinterpreted the info in the diagram and became trapped in his own errors.
It seems you all misinterpreted his original post.
what errors were his?
The part where the Sun is radiating at -18C.
