You seem to have a poor understanding of AGW theory. No one says that we "get energy from nothing". It's simply that more CO2 or other GHGs slows down the escape of heat, thereby raising temps. The claim that the theory calls for a doubling of the sun's energy is just a red-herring that has NO basis in reality.
It is you who doesn't understand the hypothesis. It is you who has discounted the actual hypothesis in favor of your own version of some sort blanket mechanism. Here, from warmist sources. I have already posted this once in this thread, which you obviously ignored.
Tutorial on the Greenhouse Effect- University of Arizona
Clip: "In this case, the Earth still gains 240 Watts/meter2 from the sun. It still loses 240 Watts/meter2 to space. However, because the atmosphere is opaque to infrared light, the surface cannot radiate directly to space as it can on a planet without greenhouse gases. Instead, this radiation to space comes from the atmosphere.
However, atmospheres radiate both up and down (just like a fire radiates heat in all directions). So although the atmosphere radiates 240 Watts/meter2 to space, it also radiates 240 Watts/meter2 toward the ground!
Therefore, the surface receives more energy than it would without an atmosphere: it gets 240 Watts/meter2 from sunlight and it gets another 240 Watts/meter2 from the atmosphere -- for a total of 480 Watts/meter2 in this simple model.
Now like the atmosphere, the Earth's surface is near an equilibrium where it gains and loses energy at almost the same rate. Because the surface gains 480 Watts/meter2 (half from sunlight and half from the atmosphere), it also must radiate 480 Watts/meter2. Unlike the atmosphere, however, the ground can only radiate in one direction -- upward. Thus, the surface radiates 480 Watts/meter2 upward, and because the atmosphere is opaque to this infrared light, it is absorbed by the atmosphere rather than escaping to space. Notice that the atmosphere, the surface, and the planet as a whole each gain energy at exactly the same rate it is lost. "
Clearly there is a claim there that the surface of the earth is receiving more energy than it gets from the sun. In order for that to happen, the atmosphere must be making energy.
Here, have another:
The Greenhouse Effect
Clip:
Absorption of longwave radiation by the atmosphere causes additional heat energy to be added to the Earths atmospheric system. The now warmer atmospheric greenhouse gas molecules begin radiating longwave energy in all directions. Over 90% of this emission of longwave energy is directed back to the Earths surface where it
once again is absorbed by the surface. The heating of the ground by the longwave radiation causes the ground surface to once again radiate, repeating the cycle described above, again and again, until no more longwave is available for absorption.
Again, the claim of free energy. Energy from no where. More energy than comes from the sun.
Why do you claim that the atmosphere acts as a blanket when the documents from your high priests say that backradiation from CO2 is actually warming the earth? Where do you get off disagreeing with climate scientists? Is it that you know that the hypothesis as stated is really a load of crap and therefore you feel the need to make up your own?
Both of the above statements violate the 2nd law of thermodynamics because they claim that heat is flowing from a cooler atmosphere to a warmer earth. They are describing a perpetual motion device caught in a positive feedback loop.
Look at your own propaganda
The energy budget shown clearly states that downdwelling radiation from GHG's are providing nearly twice as much energy to the surface of the earth as the sun AND being absorbed by the ground in addition to the energy from the sun. The energy budget clearly shows 356 Watts per square meter of surface radiation emanating from the surface of the earth when the sun is providing only 166 watts per square meter. Where is the other energy Do you actually believe that? Look at the backradiation. It clearly states that that radiation is being absorbed by the surface of the earth.
If you don't buy this hypothesis (and you clearly don't) exactly where are you getting your blanket hypothesis?
