I have been skeptical of the CO2 theory of global warming, but I've never been aware of a good alternative hypothesis before now.
CO2 is not much of a greenhouse gas, so it has always felt like "suspension of disbelief" whenever I try to figure out a way it could be the source.
In the first place, we can see CO2 effectiveness in Venus. (or rather, its lack of effectiveness.)
Venus' atmosphere is 98% CO2, and it has 10 times as much atmosphere as Earth does. Temperatures at the surface are high enough to melt lead, but..... it doesn't take much to melt lead. Since it is also closer to the Sun, all this tells me that CO2 is not much of a greenhouse gas.
Earth's atmospheric CO2 is about half of one percent. Moisture in the atmosphere is the dominant cause of greenhouse trapping of heat. There is a feedback effect, where a small amount of increased temperature one year can cause more moisture to evaporate, causing a further increase, causing more evaporation, causing further increase........ etc..... (And this continues until another effect: radiative emission, eventually stops it going further.)
So I always had to try and convince myself that this miniscule difference in CO2 content must be causing a feedback loop in the moisture evaporation.
I feel much more satisfied with the explanation from this thread.
Great work ElectricUniverse!!!

So if I did the math right, your telling me that we were in a cloud of 4kalvin which is 6740.33 F, and we are about to be entering a 1million kal cloud which is 1799540.33 F that it is a 266.981 times difference,
With the Earth's "average" template being 15C which is 59F
That in less then 100 years we will be sitting at 15,751.88 F degrees average...
