“Additionally, reaching the atmosphere is reaching Earth. If the gasses of our atmosphere are heating up, Earth is heating up. No matter which gas or combination of gasses, there is a finite amount of energy that it can hold, otherwise it would turn to plasma. It must reradiate it, some toward the ground some into space, some laterally. It really doens’t matter the energy is now part of our ecosystem. I’m not sure how you disconnect our atmosphere from the ground/oceans. In the atmosphere is on Earth.”

Well it is true that the atmosphere is part of the Earth in toto, but Anthropogenic Greenhouse Gas Warming, which is what this thread is all about, only involves the Sun heat that reaches the Earth’s surface warms it and is emitted by the surface back out towards space. Some of this surface emitted heat will be absorbed by the Greenhouse Gases in the atmosphere and emitted back at the Earth.

As NASA says at the above web site:

Satellite measurements indicate that the atmosphere radiates thermal infrared energy equivalent to 59 percent of the incoming solar energy. If the atmosphere is radiating this much, it must be absorbing that much. Where does that energy come from? Clouds, aerosols, water vapor, and ozone directly absorb 23 percent of incoming solar energy.’

‘Just as the major atmospheric gases (oxygen and nitrogen) are transparent to incoming sunlight, they are also transparent to outgoing thermal infrared. However, water vapor, carbon dioxide, methane, and other trace gases are opaque to many wavelengths of thermal infrared energy. Remember that the surface radiates the net equivalent of 17 percent of incoming solar energy as thermal infrared. However, the amount that directly escapes to space is only about 12 percent of incoming solar energy. The remaining fraction — a net 5–6 percent of incoming solar energy — is transferred to the atmosphere when greenhouse gas molecules absorb thermal infrared energy radiated by the surface. When greenhouse gas molecules absorb thermal infrared energy, their temperature rises. Like coals from a fire that are warm but not glowing, greenhouse gases then radiate an increased amount of thermal infrared energy in all directions. Heat radiated upward continues to encounter greenhouse gas molecules; those molecules absorb the heat, their temperature rises, and the amount of heat they radiate increases. At an altitude of roughly 5–6 kilometers, the concentration of greenhouse gases in the overlying atmosphere is so small that heat can radiate freely to space.
Because greenhouse gas molecules radiate heat in all directions, some of it spreads downward and ultimately comes back into contact with the Earth’s surface, where it is absorbed. The temperature of the surface becomes warmer than it would be if it were heated only by direct solar heating. This supplemental heating of the Earth’s surface by the atmosphere is the natural greenhouse effect.”

The heat energy absorbed and radiated back into space never reaches the Earth’s surface and so has no effect upon the amount of heat the Earth emits, and so it play no part in the Greenhouse Effect.
