This is only for talk about the 1st LoT. Complaining that analogies or statements. violate the 2nd LoT, Plank, or SB will be punished with one hour of listening to Marx. (Serious version: don't do it. Breaking things up helps everybody.)

Since the burden of proof is on those who go against mainstream science, you get the first words - how do you think that climate change violates the 1st LoT?

Changing the amount of CO2 in of air changes the properties of it, you can prove it experimentally with stuff in a high school lab. ergo the "greenhouse effect" is real if it violates our understanding of physical laws its our understanding that is wrong.

I paraphrase Marx; "Who are you going to believe, me or your own lying eyes?".

Consider an Earth with no atmosphere. Any heat radiated from the surface will escape from the Earth.

Now consider our Earth. Some of the radiation will be absorbed by CO2, and some of that will be radiated back to Earth. In the absence of a heat source, this would not heat the Earth, only slow its cooling. But since part of the Sun's radiation bypasses the CO2 by not being infrared, the incoming energy is decreased by less than the outgoing energy. This means that the Earth's temperature must increase.

Have you heard of Stefan-Boltzmann? That answers your questions.

The earth's atmosphere does not prevent radiation. The earth's atmosphere radiates itself. No substance can prevent its own radiation or prevent the free radiation of any other substance (or body). That radiation is governed by Stefan-Boltzmann.

jwoodward48 wrote: Now consider our Earth. Some of the radiation will be absorbed by CO2, and some of that will be radiated back to Earth. In the absence of a heat source, this would not heat the Earth, only slow its cooling.

Stefan-Boltzmann says that thermal emission is not altered. In fact, Stefan-Boltzmann says that only LOWERING earth's temperature can "slow its cooling."

This would be about the eighth time this has been clarified to you. This is clearly a pillar of your religion which demands you deny the science that destroys it. I will assume we are effectively done discussing this point.

jwoodward48 wrote: But since part of the Sun's radiation bypasses the CO2 by not being infrared, the incoming energy is decreased by less than the outgoing energy.

Nope. There is no thermal emission decrease from an atmosphere.

This means that the Earth's temperature cannot increase.

Stefan-Boltzmann does not apply to non-black/gray bodies!! Until you have proven that they do, your arguments are all unfounded.

Also, somehow the radiation from CO2 knows to always go up, not down. Otherwise, the outflow of energy would decrease, and that's IMPOSSIBLE. Like if I put a mirror in front of a light, it would have to go through, because otherwise some of it would be prevented from reaching my eyes, which is IMPOSSIBLE.

Absolutely correct. It's normally after realizing that there can be no change in the average global temperature that those of a particular "Climate" denomination will realize "I don't need for the whole planet to increase in temperature, just the surface!" Said believer will proclaim that "greenhouse effect" is a poor name because that's not really what's going on and that what's happening is that the surface is being warmed...by a cooler atmosphere and the cooler atmosphere is being cooled by the warm surface ... because it's a feedback loop of a thermal forcing!

You just pulled out the 2nd LoT in anticipation to have it ready. Kudos.

Greenhouse gases change the temperature of the Earth by changing its effective emissivity. The mechanism for this is the absorption and re-emission of upwelling IR radiation. As the concentration of GHGs in the atmosphere rises, the effective emissivity of the Earth falls. This means that the surface of the Earth has to become hotter in order to maintain the same output of radiation and satisfy LoT 1.

1. You use a real source. Actually, no, I'll be fine with you using any kind of source at all other than "my brain thought it".

2. You reference the laws of thermodynamics and radiation and then claim that a naïve application to Earth must be true. I have looked them up. Nowhere has anybody claimed that objects with different emissivity/absorbance must follow SB/Planck. I've found several good rebuttances of your "1st and 2nd LoT" arguments. Any moron could look these up. Apparently you have difficulty with this.

Then why does the S-B law have emissivity as one of its variables?


"Bodies that emit less thermal radiation than a blackbody have surface emissivities less than 1. If the surface emissivity is independent of wavelength, then the body is called a "gray" body, in that no particular wavelength (or color) is favored."

This is readily available on the internet. Gray bodies have a constant emissivity, no matter what wavelength is being radiated. No real-life objects are gray bodies, though some are gray bodies within the visible spectrum, making them look gray. Planck's Law only works for black bodies and gray bodies - other things may act similarly to black bodies, but diffuse, not-very-high-temperature gases will in fact radiate no wavelengths not present on their emission spectra.

The Laws of Radiation (Planck, S-
are like the Ideal Gas Law - they both model ideal things, and may or may not be a good approximation for a given physical object. The Ideal Gas Law is pretty good sometimes, but ideal gases don't exist, and every gas eventually departs from the Law. The Laws of Radiation are pretty good sometimes, but black/gray bodies don't exist. Why would you think that everything would obey them?

I'm sorry, guys, a bit more Internet research (which is a thing; although it is not scientific per se, it is useful as an individual to understand science better) has led me to the conclusion that the Laws of Emission do indeed apply to Earth's surface. They still don't apply to gases, though. (In fact, my Internet research has strengthened my statement on gases; I am now fairly sure that no gases will ever emit black body radiation, regardless of temperature or pressure.)

As I have repeatedly pointed out to you, simple diatomic gases such as O2 and N2 cannot radiate in the IR part of the EM spectrum because there are no available energy transitions corresponding to these wavelengths. They are able to radiate in, for example, the microwave and radio parts of the EM spectrum. This is fundamental physics.

All substances radiate per their temperature, and the wavelength of the emission is determined by the temperature.

Ergo, you are saying that there exists a temperature at which O2 and N2 cannot cool in the vacuum of space because the temperature would require an IR emission but O2 and N2 cannot emit such, so they will not radiate and will remain at the same temperature.

Your assertion is absurd.

No, according to the laws of quantum physics, isolated molecules (as in a gas) can only radiate at specific wavelengths. This is the basis of spectroscopy.

O2 and N2 will (and do) cool in the vacuum of space by emitting microwaves and radio waves. Indeed, radio astronomers can detect this radiation and thus determine the constituents of interstellar gas clouds.

No, you claimed that wavelength of radiation emitted by a substance depends solely on its temperature. This is not true. For isolated molecules, as in a gas, the wavelengths of the emitted radiation depend on the substance itself. O2 and N2, for example, cannot emit IR radiation. Other gases, such as CO2, can emit IR radiation. These are the gases we call greenhouse gases.

1. I started writing that before Surface posted.
2. I was pointing out a double standard.

Surface Detail wrote:No, you claimed that wavelength of radiation emitted by a substance depends solely on its temperature.

I stand behind that. I'm pretty sure you do as well.

1. When O2 and N2 increase in temperature, do they radiate at a greater rate?
2. When O2 and N2 cool, do they radiate less?

You stated that the existence of spectroscopy renders this false. I have no idea why you jumped into wavelengths.

Well, I don't stand behind that. Spectroscopy is the study of emission and absorption spectra, which show that gases do not radiate as black bodies - otherwise, all spectra would be identical.

The radiation emitted from O2 and N2 does indeed have a positive correlation with temperature, but this does not follow Planck's Law - they will never absorb nor emit any infrared light.
