The Greenhouse Effect
When scientists speak of the “greenhouse effect” they are talking about the way gases such as carbon dioxide and methane trap enough of the sun’s heat to warm our planet. The gases act like the sheets of glass in a greenhouse. They allow the rays of the sun in and then hold the heat inside.

In a greenhouse, the trapping of the sun’s heat allows gardeners to grow plants during cold weather. The trapping of heat that occurs during the greenhouse effect is also a good thing. In fact, it is not only good, it is necessary! Without it, our Earth would be a sphere of ice.

There is a problem with the greenhouse effect, however. The amount of gases we send into the air has increased. These gases include carbon dioxide from burning fossil fuels such as coal, gas, and oil to run factories and cars, and methane, which comes from burning trees and other vegetation. (Burning or cutting down trees without replanting them is known as deforestation.) Nitrous oxide is another gas which contributes to the greenhouse effect. It comes from sources such as some fertilizers and from burning fossil fuels and vegetation. Because the amount of gases in the atmosphere is increasing, the layer above us has grown thicker. This causes more heat to become trapped between the earth and the layer of gases. Scientists believe this is causing global warming, the warming of the earth.
