Just how does climate change work? It’s something scientists have known about for more than 150 years. The physics and chemistry is simple enough you can replicate it at home. The way carbon molecules vibrate, their shape and everything blocks infrared radiation — heat — from escaping Earth. It fills holes in the light spectrum, blocking heat’s escape path. Think of it like a blanket or a giant greenhouse. The effect makes Earth a habitable planet, but Venus next door shows there can be too much of a good thing and that’s why scientists are worried about climate change.
Many classroom and even home kitchen experiments can show this with two plastic soda bottles, some carbon dioxide, air, a strong light bulb or flame and a thermometer. Heat up a bottle with regular air and one filled with carbon dioxide in similar ways, take their temperatures and after a while the carbon dioxide filled one should warm noticeably more.
Greenhouse gases, especially carbon dioxide, “correspond to sort of holes” in the light spectrum that would otherwise allow heat to escape, but they block the exits, Mann said.
