New NASA Data Blow Gaping Hole In Global Warming Alarmism - Yahoo! NewsPlease cite and reference this proposed situation.
I know of no such situation, however, the atmospheric "greenhouse" effect returns almost as much energy to the Earth's surface as the Earth initially and directly receives from the sun. This has the rough effect of doubling the amount of energy the earth's surface would receive from the sun in an atmosphere without greenhouse gases.
Of course you don't. That you know little of the pseudoscience upon which the whole AGW hoax is buitl is abundantly clear.
Here is the energy budget upon which the hoax is based:

Actually, that's a graphical representation of Trenberth's research results, from the looks of it, his 1997 paper published in Bulletin of the American Meteorological Society February, IINM.
If you really insist on going over this again in detail, please save a copy so we can refer back to it the next time. That said, it would probably be better to us a little more up-to-date graphic as both the TOA and transfer ratios have seen some slight revisions over the last 15 years, but what are you gonna do, unlike dogma, science is always about new understandings shaping what we know and how we understand things, it would certainly be easier if the world simply conformed to the way we think it should work, but I don't want you to get all blurry eyed so let's look at what you've got,...again, <sigh>
LOL, seriously?!
"Science doesn't know about night!"
yeah okay, this isn't a preschool "teach your baby to read compendium," its time to put down the picture books and pay attention to what Trenberth's research involved and recorded. In simple, dated, graphic terms that diagram was meant to illustrate the general elements of a snapshot of the Top Of Atmosphere (TOA) energy imparted by the Sun into the Earth system, how that energy translates through and in interaction with our planet's atmosphere and surface, and then how that energy is re-emitted and transmitted through our atmosphere back out into space. The sun shines on one hemisphere of the Earth 24 hours a day, 7 days a week, 52 weeks a year, every year. When the Sun is shining on the Earth, the majority of the energy that it delivers to the Earth is in the form of visible wavelength (shortwave, red to violet light) slightly biased toward yellow, light energy. When this energy is re-emited it is in the form of InfraRed (IR) light. 100% of our Earth's surface emits longwave (IR) radiation 24 hours a day, 7 days a week, 52 weeks a year, every year.
Left-hand side of the graph we are only dealing with energy coming into the open system.
You don't count the atmosphere as part of the Earth? It's evident that Trenberth and anyone else properly reading and using his findings or that graphic should interpret the atmosphere as a very distinct and important part of the atmosphere, after all, the total solar energy impingent upon the Earth, at TOA is 341W/m^2(~100%), but the amount that reaches the atmosphere/surface boundary is only 184W/m^2(~54%) that means that elements of the atmosphere have absorbed (becoming more energetic/heating-up) or reflected nearly half of the energy impingent upon it. Looks like, from the graph, that the reflected amount from the atmosphere is 79W/m^2(~23%) meaning that the atmosphere absorbed about 78W(~23%) over the atmospheric column depth. So we have the Earth (atmosphere + surface) absorbing (161 + 78 =) 239W/m^2 (~70%) of the Sun's energy and reflecting 102W/m^2 (~30%) of the Sun's energy.
Okay, other side of the graph, and we are dealing with radiation that is present and exiting the system
No, it is saying that the warmed atmosphere is emitting a total of 532W of energy, 333W into the surface and 199W into space. But that is more a difference in completeness and perspective than substance so far.
No, at a given period, the Earth is absorbing a total of 239W/m^2 from the sun and emitting a total of 239W/m^2
The atmosphere is a part of the Earth. the entire Earth is intercepting a total of 341W/m^2 of primary solar energy, 102W/m^2 are being reflected and 239W are being absorbed directly by the atmosphere and the surface of the planet Earth. 239W are also being emitted by the atmosphere and surface of the planet to the heat sink of space.
The effect you are trying to understand is known as "insulation," it occurs when energy emitted in one portion of an object is retarded (or delayed) in its ultimate exit from that open system. Greenhouse gases act as an insulation factor delaying the exit of energy from the Earth system, as the longwave emissions bounce around a bit between the surface and the lower levels of the atmosphere before they finally escape. Increase the Greenhouse gases, increase the insulation factor. Simple century old science with a lot of very basic and solidly supporting evidence and observation throughout chemistry and physics in support of its precepts.
ever wrap an insulating blanket around a water heater?
If you insulate your room to the point that your electric heater is emitting more heat than can escape from the room, then your room will continue to warm until it reaches a point where there is as much heat escaping as there is being pumped in by the heater. In the case of the Earth, the planet is emitting as much energy as it is absorbing. so it is at rough equilibrium in its current state, as the atmospheric GHG content increases so will the insulation factor, making the planet gradually warmer while maintaining balance in absorptions and emissions.
If that confused you, it wasn't because anyone attempted to confuse anything, it is just a simple explanation of what is happening using representative values (100%) etc., comparing these values to Trenberth's we can see a pretty fair approximation.
Of course, this first graph merely represents the Left half of Trenberth's graph.
Incoming Radiation 100 341(100%)
Reflected Radiation 30 102 (30%)
Absorbed by surface 28 161 (47%)
a bit off on that one but if you look at how they've split up the emissions and absorption areas its easy to see where the difference in methodology is yielding some slightly differing values for secondary processes, and that is simply an matter of preference between the research approaches. As long as the overall numbers and major events are covered, it really doesn't matter which method you use to reflect the complicated interactions that make up the secondary and tertiary processes.
No, it says that there are 100 total units of energy being intercepted at the top of the atmosphere, 30 of these units are being reflected away and 70 units are being absorbed by the Earth's atmosphere and surface. 23 of those units absorbed by the atmosphere are re-emitted and absorbed by the surface.
This is the equivilant of the right-hand side of the Trenberth graph and is devoted to the emissions of radiation from the Earth.
We can see that it is flawed right off the bat because it shows no LW radiation incoming from the sun which is not so. Do you believe for a second that no longwave radiation from the sun reaches the earth?
The previous graph deals with incoming radiation, this one deals with internal Earth system interactions during the emission process. We start with 117 units of energy emitted by the surface, 111 of those units are absorbed by the atmosphere, 6 of those excape directly. 64 of those absorbed by the atmosphere are also re-emitted and escape (64 + 6 = 70%).
In your second chart, the red arrow on the left claims that 117 "energy units" of LW radiation is leaving the surface of the earth. The green arrow on the right claims 23 "energy units" of "latent heat" are being radiated and the pink arrow on the far left claims 7 "energy units" of "sensible heat" are being radiated. That gives a total of 147 "energy units being radiated by the surface of the earth...
No, we have 117 units of energy being emitted by the surface of the Earth, 6 units escape directly and a 111 units are absorbed by the greenhouse gases in the atmosphere and combine with the other sources of energy transfer from conduction/convection (7 units) and evaporation (23). Add in the shortwave absorption from the initial incoming radiation and we get a total atmospheric energy content of 160 units, 96 of these units are re-emitted toward and re-absorbed by the surface, 64 of these units are emitted out to space and (with the initial 6 units that escaped directly from the surface) balance out the amount of energy that the Earth (atmosphere and surface) absorbed from the sun in the first place (70%).
It really isn't complicated or confusing as long as you understand what is going on and follow the progression laid out and discussed at the site linked, which is the reason I linked the site instead of just linking a picture and then making up my own esxplanation of what the picture should be showing instead of paying attention to the information the pictures, and more importantly the research the pictures are based upon, are trying to confer.
Kinda blows a hole in all that mumbojumbo you probably just spent the last hour writing.
Must suck to spend all that time writing a bunch of nonsense, only to have it blown out of the water in one quick and easy post, eh?
