Why is carbon dioxide important for climate despite being present in small amount?
Answer and explanation
Correct answer: It can absorb outgoing longwave heat
Carbon dioxide is a greenhouse gas. Although its concentration is much lower than nitrogen and oxygen, its molecules absorb part of the outgoing longwave infrared radiation emitted by Earth and re-emit energy, influencing heat retention and climate. Option C is therefore correct. Nitrogen is the most abundant gas, oxygen supports respiration, and condensation nuclei are usually particles such as dust or salt, not the main climatic role of carbon dioxide.
