Welcome, and let’s do the molecule dance.

I learned in second-year chemistry that all molecules dance. They rotate, they vibrate, they bend and stretch. Some of the molecules in our atmosphere use infrared energy that was supposed to leave Earth for outer space. When those molecules dance, they trap that energy on Earth instead. The result is the greenhouse effect: it keeps Earth warm against the cold of outer space, nowadays, perhaps, a little too warm. But the molecules, they’re just having a good time.
