It appears I need to remind these people who are easily influenced by charlatans, that the agenda never gives solar credit for its whole influence. It's been awhile since I brought this up, but number that the IPCC et. al. use are only "direct" forcing number. Solar has an aplification, rather than feedback, so it doesn't have the same under unity gain limitation. If we assume the sun's TSI has increased by ~1.0 W/m^2 then using the 1/4 power influence for the area of the sphere vs. a disk, then this is ~0.25 W/m^2 at the TOA. However, the earths albedo is about 0.3. This means only about 0.175 W/m^2 is absorbed of the extra 1W TSI. This is where the 240 W/m^2 comes from. However, the entirety of the forcing at the surface, is over 500 W/m^2. If I use 240 being amplified to 500, then the ratio is 2.08. This means that 0.175 W/m^2 calculates out to 0.36 W/mm^2.
That is the simple linear approach. It still isn't that simple. The reason is when the TSI increases, so does the spectral peak. Almost all the extra energy is shortwave energy, the bodies of water absorb most of it, and doesn't respond like a black body does. The change is probably closer to a 0.5 or 0.6 W/m^2, but off the top of my head, I don't know the proper formula to use. This is where the IPCC fails. They claim the solar increase to be ~0.12 W/m^2 And the direct forcing change at the surface would about be that, considering my 0.175 includes atmospheric absorption. However, in reality, it is closer to my calculated 0.36 W/m^2 plus the extra energy absorbed in the oceans.
Then there is another factor I haven't mentioned yet. This extra forcing gets amplification from water vapor increases like lo0ngwave energy does too. Now if their claim of a 2:1 feedback is real for longwave, then it becomes a amplification fro shortwave as well. How close to a 2:1 it is, I can only guess. But it will bump up the 0.5 to 0.6 W/m^2 even more yet.
