The Greenhouse Effect

Many chemical compounds found in the Many chemical compounds found in the Earth’s atmosphere act as “greenhouse Earth’s atmosphere act as “greenhouse gases.” These gases allow sunlight to gases.” These gases allow sunlight to

enter the atmosphere freely. When enter the atmosphere freely. When sunlight strikes the Earth’s surface, some sunlight strikes the Earth’s surface, some of it is reflected back towards space as of it is reflected back towards space as infrared radiation (heat). Greenhouse infrared radiation (heat). Greenhouse

gases absorb this infrared radiation and gases absorb this infrared radiation and trap the heat in the atmosphere.trap the heat in the atmosphere.

What are Greenhouse Gases?

• Greenhouse gases: Gases that trap heat in the atmosphere.

Therefore the reason the solar radiation cannot escape the atmosphere after reflected off the earth is due to the

Greenhouse Gases.

Where They Come From.

• Carbon Dioxide From Fossil Fuel Combustion: (82%) Carbon Dioxide Emitted from Cars, Trains. Anything where Fissile Fuel is burned (combusted) leaving Carbon Dioxide as a remain.

• Methane: (9%) methane, comes from landfills, coal mines, oil and gas operations, and agriculture

• Nitrous Oxide: (5%) Emitted from burning fossil fuels and through the use of certain fertilizers and industrial processes

• Human Made Gases: (2%) Released as byproducts of industrial processes and through leakage.

Effects of Greenhouse gases on Climate Effects of Greenhouse gases on Climate

Rising concentrations of greenhouse gases Rising concentrations of greenhouse gases generally produce an increase in the generally produce an increase in the

average temperature of the Earthaverage temperature of the Earth

Rising temperatures may, in turn, produce Rising temperatures may, in turn, produce changes in weather, sea levels, and land changes in weather, sea levels, and land use patterns, commonly referred to as use patterns, commonly referred to as

“climate change “climate change

SolutionSolution

Since stopping the burning of fossil fuels Since stopping the burning of fossil fuels would have to great of a negative effect on would have to great of a negative effect on

our economy, our economy, We must investigate other forms of energy We must investigate other forms of energy

that would be just as affordable as fossil that would be just as affordable as fossil fuels without the negative effects or fuels without the negative effects or
