The greenhouse effect is the rise in temperature that the Earth experiences because certain gases in the atmosphere (water vapor, carbon dioxide, nitrous oxide, and methane, for example) trap energy from the sun. Without these gases, heat would escape back into space and Earth’s average temperature would be about 60ºF colder. Because of how they warm our world, these gases are referred to as greenhouse gases.
Have you ever seen a greenhouse? Most greenhouses look like a small glass house. Greenhouses are used to grow plants, especially in the winter. Greenhouses work by trapping heat from the sun. The glass panels of the greenhouse let in light but keep heat from escaping. This causes the greenhouse to heat up, much like the inside of a car parked in sunlight, and keeps the plants warm enough to live in the winter.
The Earth’s atmosphere is all around us. It is the air that we breathe. Greenhouse gases in the atmosphere behave much like the glass panes in a greenhouse. Sunlight enters the Earth's atmosphere, passing through the blanket of greenhouse gases. As it reaches the Earth's surface, land, water, and biosphere absorb the sunlight’s energy. Once absorbed, this energy is sent back into the atmosphere. Some of the energy passes back into space, but much of it remains trapped in the atmosphere by the greenhouse gases, causing our world to heat up.

Did you ever come out of an air conditioned building and get into a closed up car? That's the green house effect.

The experts say that greenhouse effect is being caused by too much carbon dioxide(CO2),etc.Personally I think that it is just another phase Earth is going through.Go back 4 million years ago and what was the planet like then.COVERED by volcanoes!What was the Earth like then?
Think about it.

Greenhouse consequence is led to by using the absorption of infrared radiation by using molecules interior the ambience that have infrared energetic bonds. to ensure that a bond to be infrared energetic, that is going to be polar (notice the finished molecule does no longer would desire to be polar, however the bonds would desire to be). subsequently, the three greatest factors of air (nitrogen, oxygen, and argon) do no longer make contributions to the greenhouse consequence. different factors of air, mutually with carbon dioxide, water vapor, and methane, do soak up infrared radiation. If it weren't for this consequence, a huge element to the warmth hitting the earth from the solar does no longer be trapped by using the ambience, and Earth's favourite temperature would be approximately -60 levels Fahrenheit.

I can't top Angel.
Thank God for the greenhouse gases otherwise we 'd all freeze to death :)
