How Quantum Mechanics Explains Global Warming

We all know that carbon dioxide is contributing to the warming of our planet, but… how, exactly? In this video, Lieven Scheire explains how quantum mechanics holds the answer.

Don’t worry: He starts off slow, using the physics of rainbows and light bulbs to describe how gases can absorb light — and why, in the case of carbon dioxide, that’s a real bad thing for us. [TED Ed]
