Hahahahahahahaahahaha. I've been here for 10 years and have seen it all. I will say, though, that many of you have switched goalposts, so there has been some progress.
We all learn as we go, (or at least we should).
I entered this debate because, of what I know about CO2 in lasers,
It is very difficult to add energy to CO2 optically, the best method is to excite nitrogen,
and have it vibration ally transfer it's energy to CO2.
CO2 alone also has some long decay states which means it would spend most of it's time
in a state where it could not absorb the 15 um photons it is suppose to.
The more I looked into the claims, the more I saw the predictions were a collection some science,
and considerable speculation.
The Science portion is pretty much limited to "CO2 is a greenhouse gas, and doubling it's level, will cause some warming."
The Science starts with how much Top of atmosphere energy imbalance would 2X CO2 cause?
That number was about 10 Wm-2 is 1896, By 1997 Hansen had it at 4 Wm-2,
IPCC AR5 had it at 3.71 Wm-2, and some recent reports place it at 3.44 Wm-2.
While the CERES satellite measures the FLUX, the number is an aggregate of all of the interactions and feedbacks
of energy in the atmosphere. For the increase in CO2 between 2001 and 2017,
the measurement would place the 2XCO2 number in the 2.5 Wm-2 range, but the data is very noisy.
Everything in AGW is descended from this energy imbalance number, If the assumptions used in the models
are in error, then all the follow on numbers are also in error.
Fruit of the poisonous assumption.
I am discussing weakness in the Science portion of AGW, the speculative portion of AGW
is that the warming caused from the added CO2 would be amplified through feedbacks to produce additional warming.
Since this is described as amplified feedback, it goes back to the science portion, what is being amplified?
If the input is considerable lower, then the output of the atmospheric amplifier will also be lower.
(The claim is that an input of 1.1 C would be amplified to between 1.5 and 4.5 C.)
