2. A THOUGHT……..
• Global warming is a threat, one that will
affect generations to come. The atmosphere
surrounding us that supports life is a God-
given gift. It must be protected.
• There is no debate among any statured
scientists of what is happening. The only
debate is the rate at which it is happening.

3. We are feeling WARM
because of exceeding
Loading Target of 49 MT.
Nothing to do with
GLOBAL WARNING..

7. In year 2050…..

11. What is global warming?

12. Global Warming
Average increase in the Earth's temperature
causes changes in the climate.
A warmer Earth may lead to changes in:
Rainfall Patterns.
Rise in sea-level.
Wide range of impacts on plants.
Wildlife.
Humans.

13. Global Warming
Earth has warmed about 1ºF over the past
hundred years.
The Earth could be getting warmer on its own’
but many of the world's leading scientists think
that the people are helping to make the warmer.

14. It should NOT be confusedIt should NOT be confused
with climate changewith climate change

15. GLOBAL WARMING
is the increase of the
Earth’s average
surface temperature
due to a build-up of
greenhouse gases in
the atmosphere.
CLIMATE CHANGE
is a broader term that
refers to long-term
changes in climate,
including average
temperature and
precipitation.

16. Greenhouse
Effect

17. Greenhouse
EffectThe glass walls and roof of a greenhouse allow
most of the sun’s light in but do not allow most
of the heat to escape. This causes the inner
temperature to be warmer than outside.
Carbon-Dioxide(CO2), and
water-vapour(H2O) acts like a
greenhouse gas, trapping heat
and making the Earth warmer.

18. Greenhouse Effect
This chart shows the warming caused by each
of the gases that human activities release.

20. Do not damage Ozone
Layer…….

21. Mars has a very thin atmosphere with a weak
Greenhouse effect. It’s surface is much colder than
Earth’s. In fact it’s frozen.

22. Venus has an intense Greenhouse effect. It’s
atmosphere is thick with Carbon-Dioxide and other
gases that trap heat. Thus, Venus’ temperature is much
higher than Earth’s—Hot enough to melt Lead.

23. Global warming…

24. How Global Warming Works
Fossil fuels (coal, oil, natural gas)
Carbon Dioxide (CO2)
Greenhouse gases

25. CAUSES OF
GLOBAL
WARMING

26. Pollution from coal,
natural gas, and oil

27. CO2 from
airplanes &
vehicles

28. POPULATION INCREASEPOPULATION INCREASE

29. DEFORESTATIONDEFORESTATION

30. Increased CO2
results in

32. 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.
Example of the
Greenhouse Effect

35. Global warming causes

36. Melting of glaciers

37. Polar Bear Extinction

38. Warmer waters and
more hurricanes

39. Increased probability
and intensity of
droughts and heat

109. AFTERTHOUGHT….
Mother Nature is healthy,
And has beauty and is wealthy
But with Global Warming in the way,
It will take Mother Nature’s beauty away
It will become hot,
Like a steaming pot
Leaves will become brown,
Then everybody will frown
We need coolness,
Not hotness
But also happiness
