nah, that's ok, still waiting on that experiment. Just cause you say so isn't good for anyone here. See, no one doubts GHG, it is the impact to the atmosphere at question and since the world believes adding 120 PPM of CO2 since the industrial age began and we're all doomed due to it, can just prove it. CO2 is logarithmic, so, once it's full it's full and adding does nothing to the power of CO2. Now you wish to argue that? Prove it!
The logarithmic aspect has been covered before in post #626 in the thread Science denialism .....
I will repeat it here.
Near the end of an absorber is where the CO2 can overcome the logarithmic saturation effect and escape. That happens at the top of the atmosphere.
If you want to relate an experiment to atmospheric physics you really have to realize that equilibrium requires that the warmth of the earth be radiated largely by what's at the TOA, which is affected by everything on down. Since CO2, CH4, H2O, etc saturate very easily,
the only way the GHGs allow radiation to escape to space is where it becomes thin enough so that the logarithmic relation does not completely block it. That is very high in the atmosphere where it is very cold. The Stefan Boltzman law does not allow much radiation to escape. That cold radiation is what causes the GHGs to become a good blanket.
If you put
more CO2 or other GHGs in the atmosphere the density becomes
richer, and pushes the mean TOA radiation point to
higher and
colder levels. The colder levels along with the Stefan-Boltzman law is what causes less radiation to escape with an increased level of CO2. That in turn causes a warmer earth.
That is why I earlier said you need a very tall experiment with liquid helium temperatures at the top of the column.
The concept is not obvious. It is covered in more detail at
Simple Models of Climate
It is essential to understand that article if you want to argue the science. Simply saying that CO2 saturates does not address what is actually happening.
