@MontereyJack,
I'm not wrong on the following:
No one claims to be able to even estimate what
percentage each of the following caused the 100-year,
1909 to 2009, 1°K (or 1°C, or 1.8°F) increase in the average global temperature:
(1) Human caused increased CO2 emissions into the atmosphere;
(2) Increased evaporation of H2O into the atmosphere;
(3) Increased SI radiations in and onto the atmosphere.
The numbers you gave me do not address these questions. I did not ask what were the IPCC's alleged
radioactive forcings 1909 to 2009. I already know the IPCC's radioactive forcings numbers are in error. For example, IPCC claims the sun's were 0.12 W/m^2. I showed you they were more than 10 times that amount.
You wrote again: "H20 is an effect of warming, not a cause." Wrong! The amouint of H2O in the atmosphere is both an effect of the temperatures of the surface and a cause. The higher the surface temperatures, the more H2O will evaporate into the atmosphere. The more H2O evaporates into the atmosphere, the more is the warming effect on the global temperature from a given amount of Solar Irradiation.
The same is true of CO2. CO2 in the atmosphere increases both because of global warming and because of human caused emissions of CO2 into the atmosphere. So to determine by what percentage a given amount of human emissions of CO2 into the atmosphere has caused a specified temperature increase, one must first determine what percentage of the CO2 in the atmosphere is caused by non-human caused emissions and what percentage is caused by human caused emissions.
