There is no evidence the sun produces a variable output over the decades, right?

Incorrect. Read The role of the Sun in 20th century climate change

Every one knows total h20 vapor in the atmosphere at all elevations, on average, is constant ... the scientists say so.

Incorrect. Scientists know that relative humidity varies with average global temperature. This is called the positive water vapor feedback.

Everyone knows that all other green house gases, on average, are negligable, except for CO2 ... the scientists say so.

Incorrect. The contributions from more potent GHGs, like methane and CFCs, are accounted for. CO2, by virtue of its concentration in the atmosphere, has the most dominant effect on Earth's radiative balance.

The computer models, written by these scientists are very trustworthy too ... minimal assumptions, incredible amounts of field data for calibration purposes, robust math equations which have minimal fudge factors, boundary conditions which are unassailable.

Incorrect. This is why the output of various models, with different assumptions and framework, must be consulted when evaluating predictions of future climate change.

Everyone knows that a huge pool of water, the ocean, holds a lot of heat, and has lots of currents going different directions at different depths. But the impact on the Carbon cycle, on average, is flat. Sez the good scientists anyway; despite how complicated all those funky currents are.

It's hard to evaluate the point of this paragraph. Ocean-atmosphere carbon exchange has been well characterized by measurements of pCO2 taken over all the ocean basins. The oceans are a net sink for CO2.

And, oh yes, salinity levels and how they change over time are very well understood as well, at all depths, and how those levels effect the heat exchange and currents between the ocean and atmosphere ... trivial, and on average, constant.

Incorrect. The effects of changes in thermohaline balance have been a very fruitful area of study. Changes such as the Younger Dryas and the 8200 ya event have shown what happens to disruption of the THC.

Yes, I know you were being sarcastic. But you were so inaccurate that I had to make sure other people reading this realized it.
