Carbon Dioxide (CO2)

The Suns energy
passes through the
cars 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.

Difference
GLOBAL WARMING
is the increase of the
Earths average
surface temperaturedue to a build-up of
