The document discusses global warming and the greenhouse effect. It explains that greenhouse gases trap heat and make Earth habitable, but the burning of fossil fuels is adding excess greenhouse gases to the atmosphere. This has caused average global temperatures to increase by 1 degree Fahrenheit over the past century. The warming is causing Arctic ice and glaciers to melt rapidly, endangering polar bears and indigenous cultures. Coral reefs are also suffering due to rising water temperatures. The document concludes by emphasizing that humans need to do their part to address this issue, as the Earth is the only planet we have.

1. GLOBAL
WARMING

2. The atmosphere has a natural
supply of "greenhouse gases“

3. They capture heat and
keep Earth warm enough

4. Without the
greenhouse effect

5. uninhabitable, frozen wasteland.

7. More and
More and more fossil fuels were burned
more
fossil fuels are being burned

8. to run our cars…

13. The gases
can stay in
the
atmosphere
for at least
50 years
and up to
centuries.

15. 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

21. Arctic ice
is
rapidly

22. Polar bears
and
indigenous
cultures are
already
suffering
from the
sea-ice loss.

23. Glaciers and mountains
Glaciers and mountain snows are rapidly melting
are slowly melting.

24. Coral reefs
which are highly sensitive to small changes in water
temperature

25. Suffered the worst bleaching-or die-off
in response to stress- ever recorded in
1998

26. We only have one beautiful planet
Earth.

27. And we are are all affected
And we
