Whatever. If you cannot understand that there is a difference between the 15 IR escaping directly into space rather than being dispersed in all directions then I don't see much of a point in endlessly repeating it.
Just a minute there IanC.
I do know the difference !
I was the one who said that CO2 absorbs 15 µm IR and the re-despirses it in all possible directions. So sayeth also all the equations when they factor in "sr", the "solid angle".
And it is the IPCC that says that a portion of the re-dispersed 15 µm IR heats planet earth...so does Hansen, so does Roy Spencer and so did you only weeks ago.
Now you start "morphing" your statements away from that and have me "not understand the difference"....in true liberal fashion I might add !
Need I dig up again
what you said when I put a thermistor in the focal point of a 6 inch reflector telescope and pointed it at a window pane that was at room temperature and at a -20 C cold country side ?
Need I dig up what you said to SSDD when he linked you to some "solar refrigerator" web pages ?
You know damn well what I said and what you have been saying...
So does everybody else who has been on this subject.
I wish you would go back and read those threads over again, and actually read my comments rather than work from your faulty memory of what you
think I said. BTW, I totally pwned you on that subject. please.....dredge it up again.
You "totally pawned" me? And now I`m supposed to spend all day and "dredge up" all the b.s. you wrote? .."rather than work from my faulty memory"...??
You are shit out of luck there, because
a.) my memory is not faulty and
b.) Your bullshit is all over the place, in fact there is so much of it that it`s hard to ignore it.
Let me refresh
your faulty memory with some samples of what you said:

The whole CO2 greenhouse theory thing has flared up again at Roy Spencer's blog (and WUWT).
here is one of the comments. it describes my position almost exactly-
Without the gasses all those photons would shoot off through the atmosphere intop space. But the GHG molecules absorb some and then radiate some of the ones they absorb back towards the earth. It doesn’t matter if they’re cooler
SSDD hurts the cause of Climate Skeptics by being so wrong headed. the Slayers hurt the cause by denying CO2
And now you say that they don`t, after I showed you several times :

[FONT=Arial, Geneva]This is equal to the difference between the sum of slope integrals for 714 and 357 ppm, related to the total integral for 357 ppm. Considering the n[SIZE=-2]3[/SIZE] band alone (as IPCC does) we get[/FONT][FONT=Arial, Geneva](9.79

[FONT=Arial, Geneva]It is hardly to be expected that for CO[SIZE=-2]2[/SIZE] doubling an increment of IR absorption at the 15 µm edges by 0.17% can cause any significant global warming or even a climate catastrophe.[/FONT]
[FONT=Arial, Geneva]The

[SIZE=-1](Hanel et al., 1971)[/SIZE] and applied to a standard atmosphere, and take an increment of 0.17%, the absorption is 0.054 W/m[SIZE=-2]2[/SIZE] - and not 4.3 W/m[SIZE=-2]2[/SIZE].[/FONT]
[FONT=Arial, Geneva]This is roughly 80 times less than IPCC's radiative forcing.[/FONT]
Your answer was:
you realize this post infuriates me, right?
is the Daly quote something that you just found? I have been saying for years that the CO2 effect is real
Not only that but you went ballistic if anybody debunked Spencer`s "Yes Virginia ", the same argument your beloved Hansen makes....objects
getting hotter with the back radiation from cooler objects.
http://www.usmessageboard.com/environment/279415-agw-atmospheric-physics-92.html#post7155354
how odd.....I find that Spencer's arguments are always stronger. not only that but he keeps trying to attack the problem from different sides to give detractors yet another opportunity to see the light.
you can magnify and direct sunlight, or output from a point source but you cannot magnify diffuse radiation from the surface or the sky to any appreciable extent at ambient temperatures.
Every post that you made so far shows that you are a total physics dimwit
So how the fck. do you "magnify sunlight" ?
That tells me that
you still don`t have clue what the difference between
power and energy is.
If I focus the number of watts that 1 m^2 receives from the sun on 1 cm^2 it is still the same amount of watts as it was before when it was spread out over 1 m^2
but you cannot magnify diffuse radiation from the surface or the sky to any appreciable extent at ambient temperatures.
No I can`t "magnify" diffused light it unless I use a photon multiplier like we do in state of the art spectrophotometers, but "mamooth" apparently can, just by painting the walls of a room white.
And you used the same idiotic mechanism to defend Spencer and Hansen over and over again.
But you have no idea how to explain it.
As soon as you get cornered by somebody who does know physics, then you got "back radiation" from a cooler object and if you boxed yourself into another corner then you start denying your "back radiation" and call it something else, like a "radiation imbalance"
http://www.usmessageboard.com/environment/279415-agw-atmospheric-physics-80.html#post7127507
therefore the object heats up when the solar oven is pointed at the sun, and the object cools down when pointed at the night time sky. all due to the imbalance of radiation. what could be more simple? how could you misunderstand that?
When you blabbered about photons from a distant red star heating up a white star it was even more ridiculous than that.
http://www.usmessageboard.com/environment/279415-agw-atmospheric-physics-81.html#post7127960
You can point the solar oven at a clear sky (away from the sun) in the daytime and still see the temperature drop to several degrees below the ambient.
Backradiation simply is not happening.
Then all over sudden back radiation is happening again:

H2O molecules absorb most bands of IR radiation from the surface (or elsewhere) and re-radiate it in a random direction just like CO2.
do the SLoTers also deny that atmospheric H2O is capable of capturing and diffusing surface IR, or reflecting it downwards from clouds?
http://www.usmessageboard.com/environment/279415-agw-atmospheric-physics-81.html#post7128506
there is a significant chance that the cooler object may radiate a higher energy photon at the warmer object than the warmer object sends back at the cooler one.
http://www.usmessageboard.com/environment/279415-agw-atmospheric-physics-75.html#post7120214
a common example of how two heat sources add to each other is two briquets, or lumps of coal or charcoal embers in a campfire will be more red on the coincident sides than the outward sides because they are losing less heat when radiating towards a warmer object than to the cooler outside that doesnt radiate back as strongly.
http://www.usmessageboard.com/environment/279415-agw-atmospheric-physics-75.html#post7120532
you 'back radiation' deniers jump from being too literal, to too general, and confuse one aspect with another.
Somebody should actually go into the other threads and collect your bullshit the way we did with "numan", "Saigon" and the mamooth bullshitter, but there is enough of it just in this thread alone.

Does simplified mean entirely different to you? The greenhouse effect as described by climate science is radiation from the atmosphere being absorbed by the surface of the earth and thereby warming the surface of the earth more than the sun alone could manage.
while I do not agree with Trenberth's energy budget, it is a reasonable place to start. it states that 161 W/m2 solar radiation is absorbed by the surface. it also has surface loss as 17 thermal, 80 evaporation and 396 radiation, for a total of 493. 493-161=332 w/m2 loss. so why isnt the surface cooling?
the other significant point is that solar radiation is shortwave and highly ordered. the IR radiation both from the surface and the atmosphere is disordered and incapable of doing work because there is no appreciable temperature differential.
You don`t even comprehend Trenberth`s version for dummies,
which shows "radiative heat transfer" as 396 from the ground up and 333 watts back radiating and ask
493-161=332 w/m2 loss. so why isnt the surface cooling?
Hasn`t it dawned on you that once you get to the top of the atmosphere that the only way (heat) energy can be shed is by radiation...only a complete idiot would add
"17 thermal, 80 evaporation and 396 radiation, for a total of 493."
Reading the rest of your crap it becomes abundantly clear that you do qualify as a idiot when it comes to physics.
you continue to ignore pointed questions about this natural process that forbids emission of radiation in certain directions.
In addition to "back radiation on or off" you also got "impeded radiation" and "forbidden radiation"...in "certain directions" and "reactive photons"
http://www.usmessageboard.com/environment/279415-agw-atmospheric-physics-65.html#post7102160
reactive photons (force carriers for electromagnetic fields), only become real if there is a particle of matter able to accept it.
interference patterns along a vector from one star to another only exist if you measure them with, you guessed it, a detector made of matter
You surpassed all the other bullshitters with that one. Electromagnetic waves cancel out if they are 180 degrees out of phase no matter if you stand in that spot with a detector or if that spot is vacant of any matter.
And that spot where they are 180 degrees out of phase does not move unless the source that emitted the light moved.
It should have dawned on you that you know nothing about physics and can`t even understand what your own "wikipedia physics lessons" ...seeing that the only people that agree with you are total dimwits:

Very well said, Ian.
You are obviously someone who knows something about physics and who has some respect for truth -- unlike the Denialist chatterbots which are programmed to lie, distort, insult and obfuscate. Why in the world are you consorting with such mindless devices?
