Why is CH₄ important in climate discussion despite its low amount in the atmosphere?
Answer and explanation
Correct answer: It can trap heat like a powerful greenhouse gas
Methane is present in a much smaller concentration than nitrogen or oxygen, but each molecule is effective at absorbing outgoing infrared radiation. Its atmospheric warming influence is therefore significant despite its low abundance. Methane also participates in atmospheric chemical reactions and has a shorter lifetime than carbon dioxide. Option C is correct; A, B and D confuse its amount, identity or role.
