"I can't help but notice how alarmists seek to minimize any natural change and I can't help but conclude it is because their primary focus is exaggeration for their Cause."
No, we minimize this because what's being talked about is not the troposphere, where every human lives, or even the stratosphere, that we may occasionally fly around in, but the thermosphere--where no one but astronauts every travel to.
The thermosphere always has a very high temperature (hundreds to thousands of degrees Celsius), but very little heat content, since its density is so low. It it becomes a bit cooler, we won't notice. It would become cooler if solar activity (sunspots, etc.) decreases, but the actual solar output wouldn't drop very much, perhaps 1 W per square meter out side the atmosphere.
Since the sun illuminates most of the Earth indirectly, and the night side not at all, this translates to a much lower value average change over the Earth's surface--you can immediately divide that change by a factor of 4. But it doesn't stop there, since the albedo of the Earth is 0.3 or so, you need to reduce it even more, so you're probably down to less than 0.2 W/m^2 change in the solar forcing. Now consider that the change in radiative forcing due to the change in CO2 in the last 40 years is about 0.9 W/m^2, so the effect due to CO2 is much greater than a possible decrease due to change in solar forcing.
So, JimZ, THAT is why scientists discount the possible change that might come about from this--it has nothing to do with the "Cause" (whatever that may be), it has to do with physics.
