How Global Warming Occurs
As we know now, global warming which is happening right now has a very big impact on natural conditions, animals and humans. Well, do you know how global warming which has a particularly serious impact on life happens? To know the process of how this phenomenon occurs, see the following explanation.
The process starts when sunlight shines the earth where most of the heat is absorbed by the earth and a half of it is reflected back onto the air (atmosphere). Sunshine returning to the air is trapped by gases in the atmosphere 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. This phenomenon causes the earth continuously getting hotter. This condition is known as global warming.
