When a bird flaps its wings, the air pushes it forward at great speed. From this, we are sure the air has great density. Even if there is no CO2 or H2O in the air that can absorb infrared radiation, there is enough O2 and N2 molecules in the air to trap heat by conduction. They pick up heat from the ground, which causes the ground to be cool otherwise the ground would be well over 100 C at day. They pass heat among themselves and with the ground otherwise the ground would be well below -100 C at night. It is conduction by molecules in the air that makes Earth hospitable to life, cool at day, warm at night.

I quote.

A piece of bare metal in space, under constant sunlight can get as hot as two-hundred-sixty (260) degrees Celsius. This is dangerous to astronauts who have to work outside the station.

A few things to note here:
1. We can actually measure the density of air.
2. You understand that all heat trapped during the day is released at night, right? This doesn't cause the overall average temperature to increase.
3. The surface isn't under constant sunlight. It's called "night."

Heat is the FLOW of thermal energy.

No substance can "trap" heat any better than a spaghetti strainer can trap water.

Conduction is a manner of transferring thermal energy, not of "trapping" it. No substance can "trap" thermal energy.

You mentioned your biology professor and your kid sister in other threads, leading me to assume that you're still a student yourself. If so, I must say that I'm pretty impressed by the quality of your posts, and I'm sure you'll go on to do well.

Perhaps either Surface Detail or yourself can list some substance that does not permit itself to thermally emit because it "traps" the thermal energy.

Then perhaps you can post the Global Warming equation.

Then perhaps you can post the science model that contains data and/or observations.

It does not trap all radiation, just some. It slows down the energy escape by back radiating some radiation to Earth again, instead of it all going to space.

It's like applying insulation to a house. The heat dissipation is slowed, but still present; if you kept your heater at enough to heat the house to 70 F before the insulation, and didn't change it after the insulation, the house would heat up.

That's positively false. Hydrogen is a better insulator than glass - the reason we don't use it for windows is that it has the annoying tendency to float away. More seriously, the atmosphere doesn't act as a thermal insulator because it can move around easily, forming convection currents. Why do you think that gas-filled windows exist?

Surface is saying "insulative" to refer to the analogy of a house. The atmosphere really acts more like a semitransparent thermos - some is let through, some is "bounced". The "bouncing" is made up of absorption and radiation, some of which is angled toward Earth.

People misuse the 2nd LoT too much. It means that the entropy of a closed system must increase. (Or maybe an isolated system?) The intuitive definitions are rarely entirely correct, or they easily lead to false assumptions.

Do you deny that absorption and radiation, some of which returns to the surface, will decrease outflow?

Well, if we ask Stefan-Boltzmann, the clear, obvious answer is "outflow increases if inflow increases" and "outflow increases if temperature increases."

Are you and Stefan-Boltzmann still not talking to each other?

Too funny.

The amount of energy that goes back down is irrelevant. Some energy is going down.

*breath*

Radiation is defined as pointing down, going down, or having the direction of "down" if the vector that describes the velocity of the photon, when using a polar coordinate system in which a vector perpendicular to the Earth's surface is of the form <0, a> where x is a positive real number, is of the form <c, d> where d is a negative nonzero real number.

What "exact offsetting balance of cooling"? If the energy emitted from the surface increases, some of the "new" outflow will also be redirected back to the surface. I don't think you understand the mathematics underlying the equilibrium I'm describing.

Did you say that some energy is emitted by the atmosphere towards the earth?

Is the atmosphere thus cooling by exactly the amount the earth is warming? Does that energy then leave the surface? That's additional cooling that wouldn't have otherwise happened, yes?

The 1st LoT says that energy can only change form. Every single example of additional warming is offset by the exact amount of cooling that you aren't mentioning. Why are you omitting all that additional cooling? Why don't you want to talk about all that additional cooling? Are you afraid that if you add it up that all that additional cooling will amount to more than the additional warming?

Well fear not! The 1st LoT says that they will BOTH always balance out and the overall average temperature will remain the same.

Warming. Cooling. Exact correspondence. Good ol' 1st LoT!

There has been no significant increase in energy absorbed by the Earth. The sun has not significantly changed, and the Earth has not significantly changed.

Will they simply "emit" or will they "re-emit" the exact same frequency that was absorbed?

I do not deny that energy is changing form, i.e. EM -> thermal -> EM -> thermal -> EM -> etc...


The amount of energy that goes back down is irrelevant. Some energy is going down.

Radiation goes in all directions, it's just not pointed.


*breath*

Radiation is defined as pointing down, going down, or having the direction of "down" if the vector that describes the velocity of the photon, when using a polar coordinate system in which a vector perpendicular to the Earth's surface is of the form <0, a> where x is a positive real number, is of the form <c, d> where d is a negative nonzero real number.

Satisfied?

You haven't shown this. You have shown that more energy leaves the surface, thus increasing surface cooling. In fact, you describe an exact offsetting balance of cooling that you strangely don't emphasize. In any event, what is clear is that you aren't accounting for everything.


What "exact offsetting balance of cooling"? If the energy emitted from the surface increases, some of the "new" outflow will also be redirected back to the surface. I don't think you understand the mathematics underlying the equilibrium I'm describing.

I suggest you start accounting for every photon *OR* go with Stefan-Boltzmann which accounts for everything without the need to discuss photons.


Except that observation of exoplanets disproves SB when used this way. I won't use a law in a situation that it does not apply to.


Enjoy your hot iced coffee then.

The second law is not violated - if the Sun were not constantly supplying energy, GHG would only slow our cooling to an inevitable icy death, not stop it. "The Sun" refutes both Creationists' and GWDeniers' use of the 2nd LoT.

There would be no difference.

You are now trying to justify the ability to make hot coffee with ice by redirection.

But can't emission be slowed? If I wrapped myself in a material of low emissivity, even ignoring conduction and convection, I wouldn't cool down as quickly, right?

Are you the heat source in your example?

Also, isn't the argument that CO2 is a super IR *absorber* and "radiator*? Isn't the argument that CO2 has a super *HIGH* emissivity? (hint:say "yes") Do you see what problems this causes those who want to get around Stefan-Boltzmann by claiming earth's emissivity is a variable and not a constant, and that CO2 affects earth's emissivity? (hint: it would drive emissivity the wrong way and show global cooling)

By the way, Surface Detail is one of those who tried to "go there" once upon a time out of desperation. It did not work out well for him.

...yes. You're right. That argument doesn't work.

Also, thank you so much for not calling anybody names or insulting people, just giving the facts and the data.

That's not slowing down emission. That's limiting it. That's like saying you can change the speed of light with a dimmer switch.

But it's "slowing it down" in the sense of reducing the rate of emission.
