How does methane contribute to the greenhouse effect?

Answer 1

Methane is a greenhouse gas (GHG), so increased amounts of it increase the greenhouse effect.

Since methane is a greenhouse gas (GHG), its concentration increases cause the greenhouse effect to intensify, trapping more and more heat at the surface of the earth.

Methane is actually far more potent than carbon dioxide, the more widely recognized greenhouse gas. However, methane is not as persistent in the environment as carbon dioxide, which is one of the reasons that carbon dioxide is usually discussed more.

Methane contributes to the greenhouse effect by absorbing and trapping heat in the Earth's atmosphere. It is a potent greenhouse gas that absorbs infrared radiation emitted by the Earth's surface, preventing it from escaping into space and thus leading to an increase in atmospheric temperature.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
