Insulated by an outer crust, the surface of the earth acquires nearly all of its heat from the sun. The only exit for this heat to take is through a door marked “Radiation.” And therein lies a tale… 

Recently, I chanced upon an Atmospheric Science Educator Guide [PDF] published by NASA. Aimed at students in grades 5 through 8, it helps teachers explain how so-called “greenhouse gases” warm our planet Earth.

These guides are interesting on a number of levels, so I recommend that you look them over. But what caught my eye was this:

• Question: Do all of the gases in our atmosphere absorb heat?
• Answer: (Allow students to discuss their ideas. Don’t provide the answer at this time.)

Indeed, that’s a good one to think over yourself. Almost all of what we’re breathing is nitrogen and oxygen — do these gases absorb heat? Lakes and rocks absorb heat, after all, and thereby reach a higher temperature. So can nitrogen and oxygen molecules do the same?

Well, I won’t keep you hanging. After allowing students to discuss it, the instructor is instructed to give them the final verdict. 

• Answer: No. Only some gases have the unique property of being able to absorb heat.

These are the infrared-absorbing “greenhouse gases,” of course, substances like carbon dioxide water vapor, and not nitrogen and oxygen. 

Now, is something wrong here? Most definitely, for NASA has a finger on the scale. Let’s review a few basics that NASA should have outlined.
