What would happen if the sun went out tomorrow?

well, as true as it is that humans aren't DIRECTLY warming the earth, the assumptions of the warmist 'CO2' model is kinda like this: CO2 is assumed to be a greenhouse gas; that is, it absorbs incoming energy (as gamma), converting it to heat, and then keep that heat from escaping the earth at night (by radiation).

So, since the sun is still involved in the process when humans [allegedly] cause the warming, having the sun go out tomorrow would be an unrelated problem. That's where that specific logic breaks down.

ON THE OTHER HAND... since the model centers ENTIRELY on the idea that CO2 is a greenhouse gas, then I like to focus my arguments on THAT little problem... because CO2 is a *REALLY* *LOUSY* greenhouse gas! It only works for temperatures below about -50F, or above about 130 or 140F, and even THEN, you have to go pretty far outside of the extremes to get 100% absorption.

When the earth emits gamma radiation at night, it's in the infrared range. "Black body radiation" puts out most of its energy at a wavelength that's close to the 'indicated temperature' wavelength, which has a simple calculation. in short, those thermometers you use with lasers in them simply figure out what the IR emission is, and 'guess' the temperature based on that. And they're pretty good.

So in short, if CO2 doesn't really absorb ANY of earth's emitted radiation between -50F and 100-something F, then CO2 isn't doing DIDDLY SQUAT to affect world temperatures, now is it?

Similarly for solar radiation, it may actually have a BLOCKING effect rather than a warming effect [and the ground absorbs the heat way better than the atmosphere does... so it's not that effective at all is it? Consider a cloudy day, for example, and water absorbs nearly ALL of the infrared, hint hint, being 100 or more times as effect ive as a greenhouse gas than CO2, in my opinion]

In any case, what would happen if the sun went out tomorrow? We'd be totally SCREWED.
