How does CO2 trap heat?

Post by robinson »

This question drives alarmists up the wall


Not the question, but the fact they can’t answer it

To save you time and effort


Here are the three main explainings that will show up


CO2 absorbs a photon and then emits it, in all directions, meaning about half of it goes back toward the planet, wHere it is absorbed by the surface and this makes the surface warmer


The second one


CO2 absorbs a photon and increases it’s energy level and transmits this energy to oxygen and nitrogen molecules, warming them up


The third one


A CO2 molecule absorbs a photon and this warms up the CO2 molecule

And before some pedant shows up to nitpick, yes, people claim CO2 levels control the climate of the planet, by trapping heat that would otherwise just go back into space

I think that's the one.

Specifically, it's in infrared wavelengths.

Visible light goes right through it, but you can see it with an infrared camera.

I refer you to the link posted above

https://scienceofdoom.com/2011/03/07/un ... art-eight/

Fascinating stuff. As you can see 95% of radiation at 15μm is absorbed in just 1 meter of atmosphere at the surface of the earth (1000 mb

Note the wording, which appears everywhere


Absorbed

The explaining that the photon is absorbed and then radiated in all directions (the tiny mirror explaining) does not match with the energy being absorbed

Or blocked

If it’s letting half the energy through (see previous explaining) it is not blocking or absorbing the energy at all


To save time, the next explaining is that “it slows the radiation from returning to space”

How does a blanket trap heat?

Unless it’s a “space” blanket in which case it also reduces radiation of heat as well

All of that could be looked up if you were actually asking, rather than being dumb

:D

I'll take your word for it.

I don't really know how to explain the physics of how a blanket works, I just know it works because I use one every night to stay warm.

I'm not trying to be dumb or troll you. I can't find it anymore, but I once saw a youtube video showing how CO2 is opaque to a thermal camera but you can see right through it with your eyes. In other words, it is transparent to visible light, but opaque to infrared light.

This is not the video, but it does show how some kinds of plastic can be transparent to visible light but opaque to infrared, while other kinds are transparent to infrared while opaque to visible.

For fun, and great justice, learning shit about IR IS PRETTY COOL

Before I started looking into the science of doom (CO2 theory) I did not know most of the energy from the sun is in the IR

55% to be exact

Which brought up all kinds of interesting paths to understanding

For example, the difference between violet and red light is the difference between a short book and a long book

The difference between near infrared (which we think of as radiant heat) and far infrared is the difference between a yard and a football field

As one can see in the diagram above, most of the IR from the sun is blocked from reaching the surface, by the atmosphere, mostly by water vapor or clouds

And by ozone

And by CO2 and some trace gases

It never reaches the ground

Came across this lecture by Lawrence Krauss. He explains this phenomenon starting at 35:59 in the video.

The flash of light you saw in the sky was not a UFO. Swamp gas from a weather balloon was trapped in a thermal pocket and reflected the light from Venus.

He actually just skips over the essential question

He does explain how CO2 “absorbs” certain infrared frequencies


But then fails to explain what happens next

Based on the video, what is the answer to the question?
