What is the greenhouse effect?

What is the greenhouse effect?
  • Natural phenomenon keeping Earth in a temperature
    range that allows life to flourish.
  • Sun's energy warms the Earth's surface and
    atmosphere.
  • Suns energy radiates back toward space as heat
  • Some heat is absorbed by trapping gases in the
    atmosphere water vapor, carbon dioxide and
    methane.

Is the greenhouse effect all bad?
  • With the temperature control of the greenhouse
    effect, the Earth has an average surface
    temperature of 59F (15C).
  • Without it, the average surface temperature would
    be 0F (-18C), a temperature so low that the
    Earth would be frozen and could not sustain life.
  • Without it, Earth would be as cold as Mars.
