Why is carbon dioxide considered climatically important despite being a minor atmospheric component?
Answer and explanation
Correct answer: Because it absorbs outgoing longwave radiation
Carbon dioxide is climatically important because it absorbs part of the longwave infrared radiation emitted by Earth’s surface. This absorption and re-emission contribute to the natural greenhouse effect and influence the planet’s heat balance. Its importance therefore depends on its radiative function, not simply on its percentage. Option A is correct; nitrogen is most abundant, ozone is different, and clouds are not solid carbon dioxide.
