3. GLOBAL WARMING
is the increase of the Earth’s
average surface temperature due
to a build-up of greenhouse gases
in the atmosphere.

4. Example of the Greenhouse Effect
The Sun’s energy
passes through the car’s
windshield.
This energy (heat) is trapped
inside the car and cannot pass
back through the windshield,
causing the inside of the car to
warm up.

in the atmosphere.
Likewise, the earth’s atmospheric gases affect the ability of the earth to radiate the Sun’s energy back into space. Nitrogen, Oxygen and Argon make up >99% of the earth’s atmospheric gases and are non-greenhouse gases. Water, Carbon Dioxide, and Methane make up <1% of the earth’s atmosphere, but are greenhouse gases, since they cause the earth to retain heat.
