The greenhouse effect of a methane molecule far exceeds the effect of a carbon dioxide molecule.

Question

Quizplus · Accepted Answer

Methane has a much higher global warming potential (GWP) than carbon dioxide. In fact, the GWP of methane is about 28 times higher than that of carbon dioxide over a 100-year time frame. This is because methane is a much more potent greenhouse gas, meaning it is able to trap much more heat in the atmosphere compared to carbon dioxide. Therefore, even though carbon dioxide is more abundant in the atmosphere, methane has a bigger effect on the greenhouse effect.
