Global warming refers to the long-term rise in the average temperature of the Earth from increased greenhouse gas emissions. The key greenhouse gases are carbon dioxide released through burning fossil fuels for energy and transportation. As greenhouse gas levels increase in the atmosphere, they trap more heat and cause the planet to warm, leading to changes in climate patterns and severe environmental impacts such as rising sea levels, stronger storms and hurricanes, more frequent droughts and heat waves. To reduce global warming, individuals and governments need to lower carbon emissions by transitioning to renewable energy, driving and flying less, improving energy efficiency, and planting more trees to absorb carbon dioxide.

2. What is Global Warming?

The changes in the
surface air temperature,
referred to as global
temperature, brought
about by the enhanced
green house effect, which
is induced by emissions
of green house gases in
the air.

3. It should NOT be confused
with climate change

4. Difference
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.

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

6. Why
Global
Warming?

7. Some of the activities of man also produce greenhouse
gases. The balance of the greenhouse gases changes
and this has effects on the whole of the planet.

8. Effects of Global Warming




Increased sea level
Changes in water supply
Rising temperature
Damage to habitats

9. Warmer waters and
more hurricanes

10. Increased probability
and intensity of
droughts and heat
waves

11. At some places, it

13. At others……

15. SOMEWHERE
it’s too…….

16. HOT

17. WHEREAS At
others too…..

18. COLD

19. WHO Is THE
CULPRIT????

21. Global Atmospheric Concentration of CO2

22. It’s NOT too LATE
ACT NOW!!!!

23. What should
be done to
reduce our
emissions?

24. Dress lightly when it’s hot instead of
turning up the air conditioning.

25. Spread awareness

26. Be Bulb Smart—Use CFLs
Compact
Fluorescent
Incandescent
