All About Global Warming

Global warming is the slow heating of our Earth, until it finally becomes too hot to live on. More and more heat would be trapped in the Earth and the temperature of places all over the world will rise.

Global warming is caused by the Greenhouse Effect.

When the sun's rays enter the Earth or escape back to outer space, some of it is reflected and some of the heat energy is absorbed and trapped by the greenhouse gases in the Earth's atmosphere. This process of trapping heat is called the Greenhouse Effect.

IGreenhouset is called the greenhouse effect because it works just like a greenhouse. Have you seen one before? A greenhouse is used to grow plants and it is made almost entirely of glass. The sun's rays are partly reflected and partly absorbed, and the plants are kept warm enough to sustain winter!

The Greenhouse Effect is actually very important, because without it, our Earth would become too cold to live on. But now, more and more greenhouse gases like carbon dioxide and methane are being produced by man, and more and more of it is entering our atmosphere and trapping more heat. Therefore, the Earth is heating up like a greenhouse.
