Plants put out CO2 at night at half of the rate they take it in during the day and the heating effect is diminished by the lack of sunlight, but don't tell "pegminer" this. He thinks that the planet can actually warm without sunlight. I'd say it has to do with his moronic arrogance!

Baccheus - You're a friggin idiot! Daytime temperatures are 20 to 30 degrees F warmer than at night on average all across the globe. That's the question. You're a bloomin idiot!

If you stop heating something, it cools down.

How fast it cools down depends on how well it's insulated.

Clouds are the best insulator. Greenhouse gasses including CO2 and water vapor are next.

Clouds also bounce solar energy back out during the day. Greenhouse gasses don't.

Your A vs B is a misstatement of the physics.

For most deniers, that would be deliberate. In your case I'm not so sure.

Well I would say, that since the CO2 levels don't really change over the time it takes the sun to rise, and then to fall... the major cause of the drop in temperature is caused by the lack of the sunlight...

Du...

Heat in heat out, during the day earth receives heat from the sun, during the night the earth radiates heat to space and cools down, this is much more noticeable in deserts as they have little water vapor in their atmosphere, water vapor slows down heating and slows down cooling, CO2 doesn't do much at all.

The planet as a whole does not cool at all in a particular time in it's daily rotation. The atmosphere on nighttime side is always cooler than than side facing the sun because the ground that warms it cools, and the ground cools because it is not receiving direct sunlight. Hopefully everyone knows that.

But why does the nighttime not freeze when there is no sunlight? The answer is the greenhouse effect. Because greenhouse gases trap heat, the atmosphere remains relatively warm during our night. The fact that nights are warming more than days is one fingerprint of global warming being due to the greenhouse effect and not to solar output. Were the warming due to solar output or cloud behavior, it would be greater during day than night.

A. When you stand next to a fire, the part of your body facing the fire warms up and the part away from the fire cools down: same thing for the same reasons.

During the nighttime hours, that portion of the earth which is not exposed to the Sun, traditionally cools down. Is that because:

(A) Lack of Sun's energy?.

(B) Level of CO2 goes down?
