GLOBAL WARMING
2
The atmosphere has a natural supply of
"greenhouse gases
3
They capture heat and keep Earth warm enough for
us to live on.
4
Without the
greenhouse effect
5
the planet would be an
frozen
uninhabitable,
wasteland.
6
Over the past 300 years, people started emitting
large amounts of greenhouse gases
7
More and more
More and more fossil fuels were burned

Adding to our naturalsupply of
greenhouse gases.
13
The gases can stay in the atmosphere for at least
50 years and up to centuries.
14
The result?
15
the globe
has heated up by about one degree Fahrenheit over
the past century.
16
One degree not a big deal?
Consider this
17
the difference
in global average
temperatures between modern times
18
and the last ice age
19
was only about
9 degrees Fahrenheit.

America is the 1 global warming polluter in the
world.
