How a Global Warming Happens

Global warming is the increase of global temparature surface that happens because of green house effect. Global warming has a bad impact to human, animal, and plant. It makes the earth is too hot to life sustain. But how does global warming happen?

Global warming happens when carbon dioxide (CO2),other air pollutants and greenhouse gasses collect in the atmosphere. The process start when sunlight shines the earth then most of the heat is absorbed by the earth and the half of heat is reflected back to the atmosphere. Sunshine that returned back to the air is contained a lot of polutan gasses such as carbon dioxide, sulfur dioxide, methane, water vapor, and so on. This event is known as the greenhouse effect.

Solar radiation on the earth's atmosphere makes ozone layer get thinner and makes the sunlight which shines the Earth become hotter. The greenhouse effect also causes the sunlight which is reflected back onto space is reflected back into the earth.

Normally, this radiation would escape into space—but these pollutants, which can last for years to centuries in the atmosphere, trap the heat and cause the planet to get hotter. That's what's known as the greenhouse effect. This is how a global warming happened.
