Without naturally occurring greenhouse gases, Earth’s average surface temperature would be near 0 degF instead of the much warmer 59 degF. Paradoxically, the top of the atmosphere would also be near 0 degF instead of the much cooler -59 degF. That is the effect of gravity on the atmosphere. Gravity does work by compressing the atmosphere, converting potential energy into thermal energy. This also gives the atmosphere a lapse rate of temperature, which distributes the thermal energy across the depth of the of air, from the warm surface layer to the coolest layer at the top. Thus, the atmosphere acts like an insulator and greenhouse gases have everything to with that.
Going back to your original post, I still find the first argument, why global warming is important despite apparent saturation when man adds CO2 to the atmosphere, extremely difficult to follow (although your statement of it is the clearest I’ve seen).
The Greenhouse Effect and Global Warming - …
Humanity has decimated the biosphere in countless ways, there is no rational argument to deny this fact. This being said, the single greatest decimating factor far, based on all available data, is the ongoing global weather modification/geoengineering programs. , completely disrupted hydrological cycle, altered wind and ocean currents, triggering life threatening climate feedback loops (methane release), the loss of our once blue skies and photosynthesis, and the literal poisoning of all life on Earth from the fallout. This is their "cure" for the climate disruption largely caused by the geoengineering programs to begin with.
The Greenhouse Effect - University of California, San Diego
Therefore the main physics arguement supporting enhanced global warming caused by increasing levels of CO2 is the in height and thereby lower temperature of the effective radiating level of the atmosphere to space. The first comment to make is that we never hear this crucial explanation in the popular descriptions of the greenhouse effect. We just hear that more CO2 absorbs more heat radiated from the earth and radiates it back to the surface thereby heating us up just like a thicker blanket does in bed (blankets actually work by cutting down convection losses). However the real explanation above concerns just the outermost layers of the atmosphere. The enhanced greenhouse effect depends on a decreasing temperature gradient with height so that as the effective radiating level for IR by CO2 rises so the energy loss falls and the earth must rise in temperature to compensate. Energy balance demands that there is a perfect match between incoming solar energy and outgoing IR energy. So lets look at this in more detail.

Climate change includes any change resulting from different factors, like deforestation or an increase in greenhouse gases. Global warming is one type of climate change, and it refers to the increasing temperature of the surface of Earth. According to NASA, the term global warming gained popular use after geochemist Wallace Broecker published a 1975 paper titled Climatic Change: Are We on the Brink of a Pronounced Global Warming?

There are two sides of the global warming argument: believers who think that global warming is a huge environmental threat, and skeptics who say that global warming doesn't even exist.
