Global Warming

Nicholas DeJarnette

What is global warming?

Global warming is the overall rise in the temperature on the Earth’s surface.

How does the Earth get hotter?• Carbon Dioxide

• Methane

• Chlorofluorocarbons

• Ozone

• Nitrous Oxide

The sun sends visible light to the earth. The earth absorbs some of the light and releases the rest back into space this released energy is known as infrared radiation. Some of the released energy is emitted back to the earth by gases in the atmosphere, these gases are called greenhouse gases. When the light is re-emitted this causes global warming.

IN CLOSING• We learned that global warming is the overall rise in the

temperature on the earth’s surface. • We learned how greenhouse gases heat the earth even more

by re-emitting the earth’s released energy.• We learned that carbon dioxide, methane,

Chlorofluorocarbons, ozone, and nitrous oxide are all greenhouse gases.

• We learned about the major rise in carbon dioxide and its effects it has on the earth.

• Finally we learned about how the government has attempted to limit the pollution on the earth.
