Why is methane considered important among minor atmospheric components?
Answer and explanation
Correct answer: Because it is a powerful greenhouse gas
Methane is present in much smaller concentration than nitrogen or oxygen, but each methane molecule absorbs infrared radiation efficiently in important wavelength bands. Consequently, changes in methane concentration can influence radiative forcing and climate even though methane is a minor atmospheric component. It also has a shorter atmospheric lifetime than carbon dioxide, making its effects and mitigation timescales different. Option A is correct; methane is not the main respiratory gas, the most abundant permanent gas, or solid dust.
