While there was a mild hoopla when I stated that the IPCC Down Welling Longwave Radiation Violates the Law, that died quickly because it wasn't the first time that claim had been made. Most, other than the IPCC of course, are more than aware that it is true. Many of the rejectionists, people believing that CO2 has no impact on climate, didn't find my results Earth shattering enough to be worthy of attention.
Matters of Scale are always worthy of attention. Instead of a doubling of CO2 causing 4.5 degrees warming, or 3 degrees warming or 2 degrees warming or even 1.2 degrees warming, it will be more like 0.8 to 1 degree of warming. Just for grins let's say 0.8 is the definitive value, though that is in no way certain.
Then, if solar average variation can produce a 0.1 degree change, 0.1/0.8=0.125 or 12.5% of climate variability may be due to solar all by itself. Natural vari8ability is considered to cause 10% of climate change by people believing CO2 double WILL cause 3 degrees of warming, 10% of 3 is 0.3, so natural variability now, assuming their estimate was in anyway based on sound math, 0.3/0.8=0.375 or 37.5 percent of climate variability is natural.
Solar should be considered natural, but the climate models include both solar and natural variability. Combined, 0.1 and 0.3 or 0.4 would be 50% of the climate variability.
Isn't it amazing how such a small change can make such a large difference?
