2. Global warming is not new as this
process occurs naturally and keeps
the Earth’s temperature about 50
degrees Fahrenheit warmer than it
would be otherwise. Without this
natural cover, Earth’s surface would
be colder than it is today,, making
the planet freezing and devoid off
life.

3. What is global warming?
The changes in the surface air
temperature, referred to as the
global temperature, brought about
by the enhanced greenhouse
effect, which is induced by
emissions of greenhouse gases
(deoxis carbon , methane, oxides
of nitrous )into the air.

4. 1-Natural Causes
release of methane gas from arctic tundra and wetlands.
Methane is a greenhouse gas.
A greenhouse gas is a gas that
traps heat in the earth's atmosphere.
Sun

5. 2- human -made Causes
1-Pollution
-Burning fossil fuels (coal, oil) => CO2

6. 2. Population
Since CO2 contributes to
global warming, the
increase in population
makes the problem
worse because we
breathe out CO2.
3. Transportation

7. 4.Deforestation
the trees that convert our CO2 to
oxygen are being demolished
because we're using the land that
we cut the trees down from as
property for our homes and
buildings.

8. Effects
 Health
 Water resources
 Polar regions
 Mountains
 Forests
 Deserts
 Coastal Zones
 Agriculture
 International

11. 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.
What’s the difference between “global
warming” and “climate change”?

14. What can you do to help
solve the problem?

15. Simple Things To Do
Turn off your computer or the TV
when you’re not using it.
Take shorter showers. Heating water uses energy.
Keep rooms cool by closing the blinds, shades, or
curtains.
Turn off the lights when you leave a room.
Use compact fluorescent bulbs.
Plant a tree Recycle.

16. Conclusion
Global warming is affecting plants, animals,
humans and the earth. We need to learn how
to conserve our use of fossil fuels to minimize
carbon dioxide production. This will slow
down the effects of global warming.
