EPA Climate Change Kids Site: The greenhouse effect is the rise in temperature that the Earth experiences because certain gases in the atmosphere trap energy from the sun. Without these gases, heat would escape back into space and Earth&'s average temperature would be about 60ºF colder. ... The greenhouse effect is important.

There is a greenhouse effect, but, if there were not, we would all be dead! It is becoming increasingly clear that we are also experencing global warming, but, that is a different matter. Global warming is the name given to an expected increase in the magnitude of the greenhouse effect, whereby the surface of the...

This is called the Greenhouse Effect . Over the past century, the Earth has increased in temperature by about .5 degrees Celsius and many scientists believe this is because of an increase in concentration of the main greenhouse gases: carbon dioxide, methane, nitrous oxide, and fluorocarbons.

These climatic changes are caused by the greenhouse effect. In the atmosphere energy in the form of light streams towards the earth. It passes through layers of gasses miles above the surface of the earth, as the sun heats the land and the sea, energy is reflected back at the gasses.
