3. INTRODUCTION OF GLOBAL WARMING
Global warming is the ongoing rise of the average temperature
of the Earth's climate system and has been demonstrated by
direct temperature measurements and by measurements of
various effects of the warming.

5. CAUSES OF GLOBAL WARMING
• Emission of green house gases like carbon dioxide,
methane , nitrous oxide etc into the atmosphere.
• The major source is carbon dioxide (80%).
• 20% by methane and nitrous oxide.

7. CARBON DIOXIDE
• The major source of carbon dioxide is the power
plants.
• Burning of fossil fuels for the purpose of electricity
generation.
• About twenty percent of carbon dioxide emitted in the
atmosphere comes from burning of gasoline in the
engines of the vehical

8. METHANE
• Methane is more than 20 times as effectual as CO2
at entrapping heat in the atmosphere.
• Methane is obtained from resources such as rich
paddies, bovine flatulence, bacteria in bags and
fossil fuel manufacture.

9. NITROUS OXIDES
• the main sources of nitrous oxide include nylon and
nitric acid producton, cars with catalytic converters
the use of fertilizers in agriculture and the burning
of organic matter.

10. WHO IS RESPONSIBLE FOR GLOBAL WARMING
The Intergovernmental Panel on Climate Change (IPCC)
concluded that "human influence on climate has been the
dominant cause of observed warming since the mid-20th
century"

11. GREEN HOUSE EFFECTS
• The green house effect is when the temperature
rises because the sun heat and light is trapped in
the earth atmosphere.
• The heat and light can get through the atmosphere,
but it can’t get out. As a result, the temperature
rises.
• Sometimes the temperature can change in a way
that helps us

13. HOW CAN WE STOP GLOBAL WARMING
Change a light
Replacing one regular light bulb with a compact fluorescent light bulb will save 150
pounds of carbon dioxide a year.
Drive less
Walk, bike, carpool or take mass transit more often. You'll save one pound of carbon
dioxide for every mile you don't drive!
Recycle more
You can save 2,400 pounds of carbon dioxide per year by recycling just half of your
household waste.
Check your tires
Keeping your tires inflated properly can improve your gas mileage by more than 3 percent.
Every gallon of gasoline saved keeps 20 pounds of carbon dioxide out of the atmosphere.
Use less hot water
It takes a lot of energy to heat water. Use less hot water by taking shorter and cooler
showers and washing your clothes in cold or warm instead of hot water (more than 500
pounds of carbon dioxide saved per year).

14. AVOID PRODUCTS WITH A LOT OF PACKAGING
YOU CAN SAVE 1,200 POUNDS OF CARBON DIOXIDE IF YOU REDUCE YOUR
GARBAGE BY 10 PERCENT.
ADJUST YOUR THERMOSTAT
MOVING YOUR THERMOSTAT DOWN JUST 2 DEGREES IN WINTER AND UP 2
DEGREES IN SUMMER COULD SAVE ABOUT 2,000 POUNDS OF CARBON
DIOXIDE A YEAR.
PLANT A TREE
A SINGLE TREE WILL ABSORB ONE TON OF CARBON DIOXIDE OVER ITS
LIFETIME.
TURN OFF ELECTRONIC DEVICES
SIMPLY TURNING OFF YOUR TELEVISION, DVD PLAYER, STEREO, AND
COMPUTER, WHEN YOU'RE NOT USING THEM, WILL SAVE YOU THOUSANDS OF
POUNDS OF CARBON DIOXIDE A YEAR.

15. CONCLUSION
The ‘Conclusion’ confirms that global warming is the major
challenge for our global society. There is very little doubt that global
warming will change our climate in the next century. So what are
the solutions to global warming? First, there must be an
international political solution. Second, funding for developing
cheap and clean energy production must be increased, as all
economic development is based on increasing energy usage. We
must not pin all our hopes on global politics and clean energy
technology, so we must prepare for the worst and adapt. If
implemented now, a lot of the costs and damage that could be
caused by changing climate can be mitigated.
