What is the most abundant greenhouse gas in our atmosphere?

Answer 1

Water vapor.

The amount of water vapor in the air is the highest of all greenhouse gases, making up about 0.4% of the atmosphere. The reason water vapor is rarely discussed is twofold: first, the amount varies greatly depending on location, and second, and most importantly, the amount is not rising dramatically.

With a relative abundance of 0.04%, carbon dioxide is the second most abundant greenhouse gas, and human activity is causing its concentration to rise dramatically.

Answer 2

Water vapor.

The infra-red region of the Earth is home to a variety of bands where electromagnetic radiation is absorbed by water vapor. The mass of water vapor in the atmosphere is approximately 2%, while that of carbon dioxide is approximately 0.04%. The temperature of Earth is not affected by greenhouse gases, either at the surface or at the ocean's depths.

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.
