Why will the earth become hot?

Source: JEA 1997

The sunshine is absorbed by the ground. The ground heated by the sunshine reflects infrared radiation which warms the atmosphere. Green house gases absorb the heat of infrared radiation and also reflect heat. As a result, the temperature on the earth is kept at the level which is adequate for the existence of life. Recently, however, green house gases have increased due to human activities and global warming has been accelerated. Human activities, such as development of industries and forest cuts, have led to an increase in green house gas concentration.
