The Story of the Sun and the Earth and Greenhouse gases!
Before the greenhouse gases came, the Earth was very cold. Even if solar radiation came down on it, part of it reflected back to space and the Earth was still cold.

Their ability to absorb heat helped warm the Earth to a comfortable temperature that could support life.
But everything was about to change. One day, the greenhouse gases showed up in the atmosphere.
As humans start to populate the planet their demand for energy grows. As they start to use electricity from coal-fired power plants and gasoline to power vehicles, the amount of greenhouse gases going unto the atmosphere starts to increase.
