But greenhouse gases like CO2 then emit a photon, that can bump into neighbouring oxygen molecules.

Any individual hydrocarbon molecule in your gasoline might contain six, or seven, or eight, or etc. atoms of Carbon, and each ONE of those Carbon atoms can create a molecule of CO2, when combined with Oxygen gas.

Only greenhouse gases like CO2 absorb IR, and they collide with other molecules like oxygen, and so everything heats up.

Almost immediately (nanoseconds) they relax from their excited state by either 1) emitting that energy as a new photon, some of which will continue up towards space, some of which will go back downward to be reabsorbed, thus keeping the energy in the atmosphere longer, or 2) by colliding with another gas molecule, most likely an O2 (oxygen) or N2 (nitrogen) molecule since they make up over 98 % of the atmosphere, thereby converting the extra vibrational energy into kinetic energy by transferring it to the other gas molecule, which will then collide with other molecules, and so on, making the air warmer.

He found that gases and vapors whose molecules had three or more atoms, such as water vapor and CO2, absorbed much more of the thermal radiation passing through the tube than did two - atom molecules such as oxygen and nitrogen.

For every million molecules of other gases in the atmosphere (such as nitrogen, oxygen, and hydrogen), there are only 385 molecules of CO2.

Compare with electronic transition absorption of visible light by the electrons of the molecules of nitrogen and oxygen in the atmosphere, the real gas Air, which is what gives us our blue sky, reflection / scattering.

Often the CO2 will strike one of the oxygen or nitrogen molecules which make up the great majority of atmospheric gases, setting them in motion, too — warming them.

The example I've given is of visible light in the atmosphere being bounced around the sky, actually reflected / scattered, by the electrons of the molecules of nitrogen and oxygen which comprise c98 % of our fluid gas atmosphere.

Most of the gas molecules in our atmosphere are nitrogen (N2) and oxygen (O2).

Because the molecules in a gas are constantly moving about and colliding with each other, it is very likely that some nearby nitrogen or oxygen molecule will collide with our excited infrared - active gas molecule before it has a chance to emit its light.

Since the infrared - inactive gases don't emit infrared light, if enough absorbed energy is transferred to the nitrogen and oxygen molecules through collisions, that could theoretically increase the average energy of the air molecules, i.e., it could «heat up» the air.

When water molecules rise high in an atmosphere, ultraviolet radiation split the water molecules into its component gases, oxygen and hydrogen, and the lighter hydrogen molecules escape into space.

Global warming is implicated in the loss of Arctic ozone because greenhouse gases trap energy lower down, heating up the atmosphere nearer the ground but cooling the stratosphere, creating conditions conducive to the formation of the reactive chemicals that break apart the three - oxygen molecules of ozone.

The best way to do this, in my opinion, is using a fuel cell — a device that can electrochemically convert natural gas into a useable fuel by stripping off the hydrogen portion of the methane molecule and combining it with oxygen to generate clean electricity and some waste heat.

Oxygen (O2) has only two atoms per molecule, whereas carbon dioxide (CO2) and other greenhouse gases have three atoms or more.
