ABSTRACT
This article explains the greenhouse effect and global warming. Many scientists believe that gases in the air are causing Earth's climate to become warmer. This is called global warming. In Earth's atmosphere there are tiny amounts of gases called greenhouse gases. These gases let the rays of the sun pass through to the planet, but they hold in the heat that comes up from the sun-warmed Earth--just as the glass of a greenhouse holds in the warmth of the sun. These gases increase the thickness of the greenhouse "glass," causing too much heat to be trapped. This is called the greenhouse effect.
