Global Warming and the Greenhouse Effect

Global warming is a hot topic nowadays. No doubt, the temperature is increasing all over the globe. This is due to the increase of greenhouse gases in the atmosphere.

Greenhouse Gases and Greenhouse Effect?

The greenhouse effect is, in fact, a natural thing that takes place to keep the Earth’s climate warm and habitable. When the visible light penetrates through the Earth’s atmospheric system, on average, 51% of the sun’s radiation reaches the surface, hence heating the ground. The heating of the ground by sunlight causes the Earth’s surface to become a radiator of energy in the long wave band (sometimes called infrared radiation). Generally, the energy is directed back to space but little manage to make it back because they are absorbed by the greenhouse gases.

The main gases in our atmosphere that contributes to the greenhouse effect are carbon dioxide, methane and water. Sad to say, the greenhouse effect turns nasty when the amount of greenhouse gases, especially carbon dioxide due to fossil fuel burning, increases. The trapping of infrared radiation by these greenhouse gases increase heat on the earth atmospheric system.
