How does Carbon Dioxide Cool the earth?

Answer 1

When sunlight hits the earth some parts of it absorbs and some parts of it converts to heat waves that reflects. But CO2 does not permit the reflected wave to go out of the atmosphere and it's like a greenhouse so the earth get warmer.

Answer 2

Carbon Dioxide, or any element in the atmosphere that reflects heat from the earth will actually cool the planet. Remember, the heat that carbon dioxide reflects back to the earth came from the sun originally, or in other words outside of the atmosphere. carbon dioxide would actually reflect heat before it enters earth's atmosphere, and because there is more heat to reflect, (because none of it has been absorbed by earth yet) it would actually cool the earth. -I just saw Al Gore's presentation (An Inconvienent Truth), and thought about his reasoning, and this is the conclusion I logically came up with.

Answer 3

Carbon dioxide in the atmosphere traps heat from the sun, leading to the greenhouse effect. This effect warms the Earth's surface. However, excess carbon dioxide can also cause more heat to escape into space, leading to cooling effects like increased cloud formation and lower temperatures in the stratosphere.
