GP is likely trolling, but CO2 does work in the night the same as in the day. It keeps in infrared radiation emitted by the earth and things on the surface, like you. You won't have a temperature increase, but you'll have less cooling.
In that example, you'd need some structure to keep it in, since the parcel of air will eventually mix with its neighbors, and you can't breathe in the CO2. The structure itself would provide a greater greenhouse effect than the CO2 since it basically would be a greenhouse. But if you tested a windowed shelter filled with CO2 and one with normal air, Mythbusters-style, I suspect you'd find a measurable difference.
- GlobalChange 11y agoSince you mentioned the mythbusters, that episode is really wrong, though I really love it because it is the only one of its kind I know of that uses more than two gases. There is a real flaw there, which is the same in all those kind of experiments actually. And it is a real scientific flaw. If it were to be done properly, that would be interesting and I would bet it would reveal surprising results. As you mentioned, a structure is required. The CO2 is useless. By the way, on a greenhouse, CO2 has no function regarding temperature.
