What is the most abundant greenhouse gas in our atmosphere?
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.

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.
