CO2 Science dependent modern marvels. For your consideration.

In light of recent 'dialogues' I've had with Dave NC-20 Burton and others which reveal a profound self-inflicted ignorance and an even worse disinterest in giving climate science a fair shake, (that would be sans politically motivated fantasizing about grand conspiracy theories, slander towards accomplished experts and such paranoid thinking.) I'd like to share the reasons I, a non-expert, feel comfortable trusting the scientific community rather than passionate partisans of profits über alles.

This post is an interesting sort of one way collaborative effort.  
You see, over the years I've communicated with a number of scientists and grads.  Asking straight forward questions and often receiving informative replies.  I try not to over do my welcome, after all these are very busy people with more important things to do.

But for this post I sent a grand shout out to a number of my correspondence pals and received more responses than I expected including some informative surprises for me. 

I have taken great liberty slicing and dicing their responses. Rewriting some, leaving other quotes untouched and giving all of it some order.

I mention this because I want to be clear the following List of "CO2 science dependent" modern marvels is not my own cleverness and I want to send out a big Thank You! to my informed anonymous heroes!

The increase in atmospheric concentration of CO2 since preindustrial times is a given. Understand that the radiative physics of greenhouse gases are very well-understood.

Consider heat seeking missiles flying through different altitudes searching for a heat source who's signature is changing with altitude.  In order to program the computer, the programmer must know how to accurately compensate for the changing signature.  It requires a complete knowledge of the radiative properties of all the gases in the atmosphere, or all that hardware is for naught.

{Incidentally, there is not one contrarian "theory" or challenge to the physics that hasn't been looked at by informed individuals.  You just have to poke around*, you'll find that contrarian errors, omissions, and falsifications have been clearly explained.      *Or you can check out this one stop resource:

The Republican/libertarian PR machine makes its career out of ignoring all those treasure troves of valuable valid information, because they are scared of it.  It's very human, but cowardly just the same, but I digress.}

You may ask, by what right am I so sure about it? 
It comes down to, down to Earth reality over self-serving fantasizing.

Please consider the real life modern marvels that would be impossible without such understanding:

~ ~ ~ ~ ~ ~ ~
* Weather satellites that can image heat and moisture and wind's effects into comprehensible images.
~ ~ ~ ~ ~ ~ ~
* Precipitable water. Contrast brightness temperatures measured via oxygen emissions and via H2O emissions to back calculate how much water is present.
~ ~ ~ ~ ~ ~ ~
* Heat seeking air to air missiles, they would not function if those guidence computers didn't have a complete description of how heat moves through the atmosphere.
~ ~ ~ ~ ~ ~ ~
* Early-Warning satellites.  How are they going to distinguish between a missile launch from lightning, over Siberia?  Better look at IR in DETAIL!

Spectroscopic Databases such as HiTran and Geisa have military origins. Going back to WWII and the desire to do Night Bombing better. Then this continued during research programs in the 50's & 60's, with a lot of it through the Cambridge Research Laboratory.

The program ModTran that is an example of a narrow band Radiative Transfer Code, for calculating radiative transfer. Half the patents for this are held by the Pentagon. The company that develops it - Spectral Sciences Inc - does so under license to the United States Air Force.

For 20 years developments to ModTran were signed off by the Commandant of the USAF GeoPhysics Laboratory, Hanscom AFB, Ma. These days it is the responsibility of the Commandant, the USAF Laboratory, Kirtland AFB, NM.

*  Lasers wouldn't work if we had radiative physics wrong.
~ ~ ~ ~ ~ ~ ~
*  The detection of specific chemicals in the atmospheres of exoplanets: 
By modeling the gases at high pressures, you can produce an expected absorption for infrared from the planet and compare the model to the spectra recorded by the Spitzer space telescope
~ ~ ~ ~ ~ ~ ~
*Spectroscopy includes measurement of absorption of IR wavelengths
eg measurement of CO2 levels in the atmosphere and ice cores relies on IR absorption. (that would make using ice core records to "prove" GHE doesn't exists amusing)
"Each sample has a volume of 4~6 cm3. CO2 concentration was measured with IR tunable diode laser spectroscopy, scanning a single vibrational-rotational absorption line."
~ ~ ~ ~ ~ ~ ~
*  And it's not just physics of the standard GH gases.
  • Microwave emissions of oxygen molecules gives us satellite temperature sensing of the atmosphere.
  • Nitrogen - Nitrogen collisions form part of the basis of the GH effect on places like Saturn's moon Titan.
~ ~ ~ ~ ~ ~ ~ 
*  Getting out of the IR range, but the Dobson spectrophotometer designed in 1924 to measure ozone (and the standard instrument for doing so, for many years) is based on the application of Beers Law. Using two close wavelengths that differ mainly in their O3 absorption coefficients, total column O3 is determined by the difference in transmission (sun view).
Careful selection of wavelengths allows measurement of many atmospheric gases.
IR instruments for CO2 and H2O are off-the-shelf items.

But wait, there's more . . .

The Atmospheric Propagation and Effect department focuses on laser applications in the open atmosphere. Main topics are the use of laser radiation over long distances, such as optical energy transmission (laser power beaming, laser-based air defence) and the remote detection of pollutants and hazardous substances.

Unknown on 2/1/19 - I have a comment policy, only serious constructive comments or challenges are accepting. Non sequiturs and links to hermetically sealed conspiracy theory sites won’t cut it.

If you keep it within your echo-chamber and you also refuse to look at any evidence that contradicts your assumption, then you can say and believe anything you want - no matter how idiotic and disconnected from reality.

Science is about accumulating as much evidence as possible and constructive learning from it.

The Lavoisier Group is a global warming skeptic organisation, based in Australia. It argues that the evidence for global warming is based on inexact science and that any policy responses, such as signing the Kyoto Protocol, would be too expensive for Australia's industry.

The group is closely associated with the Australian mining industry, and was founded in 2000 by Ray Evans, then an executive at Western Mining Corporation (WMC), who was also involved in founding the HR Nicholls Society and the Bennelong Society. Hugh Morgan, former WMC boss and head of the Business Council of Australia until 2005, delivered the group's inaugural speech.

In 2001 Australian economist John Quiggin wrote that the Lavoisier Group is "devoted to the proposition that basic principles of physics...cease to apply when they come into conflict with the interests of the Australian coal industry." [1]
