Why is CH4 given high importance in climate studies despite being a trace gas?
Answer and explanation
Correct answer: Because its heat-trapping ability can be effective
The governing concept is the radiative importance of trace greenhouse gases. Methane absorbs infrared radiation in wavelength bands that influence Earth’s outgoing energy, so a small concentration can still contribute meaningfully to warming. Its climatic importance depends on both its abundance and its heat-trapping efficiency. Option C is correct. Methane is not the main atmospheric gas, is not solid nitrogen, and does not destroy all clouds, making A, B and D incorrect.
