And where does the heat go then? It must go somewhere, otherwise the surrounding air would just keep getting hotter!


Space. The air has a radiance just like the surface does.

You DO know about radiance, don't you? It's proportional to temperature, you know.

So you reckon the heat from the atmosphere goes up but not down? How does it know not to go down?


I notice I made an entry error so I'll correct that first: H20 in just its vapor stage is 100 more common than CO2. (4% vs .04%) And it absorbs infrared heat from almost the entire bandwidth with only a few openings in its bandwidth.

And in general yes - heat only goes up. It mixes in the atmosphere via conduction and rises due to convection. If the rising air mass is warmer than the air above it convection drives the heavier air mass downwards. If not it uses conduction to pass the heat around until it is warmer than the mass above it.

But then all you have to do is turn on the TV weather reports and they could explain this to you.

Generally correct.

Most radiance comes from the surface itself.

Water vapor does not stop or trap energy. Any light that is absorbs is converted to thermal energy. The water vapor is still cooler than the surface beneath it. It still radiates energy though, just not as much as the surface. It is still above absolute zero.

Meh. Same thing happens

Yes. it is. It's all the same kind of thing. All of these substances happen to absorb infrared energy, helping to cool the surface of the Earth. All of these substances are above absolute zero. The radiate their own energy according to their temperature.

We're talking about radiated heat, you idiot. Heat that is radiated by the atmosphere is transmitted equally in all directions. Some of it reaches the ground. We refer to this as back radiation.


You cannot heat a warmer substance with a colder one. It doesn't matter if you use conduction or radiance to do it. You are STILL trying to make hot coffee with ice. You are STILL trying to violate the 2nd law of thermodynamics and the Stefan-Boltzmann law.

Most of Earth's radiance comes directly from the surface itself.

Why don't you tell us how this heat is radiated? You really don't have a clue what you're talking about and somehow have the idea that radiation occurs to any sensible amount in the troposphere.

It does. The troposphere has mass. That mass is above absolute zero. It has a radiance, same as any mass.
