2. OVERVIEW:  INTRODUCTION  CAUSES  EFFECT  PREVENTION  CONCLUSION 2

3. INTRODUCTION “GLOBAL WARMING” Increase in World temperature. The natural greenhouse effect. Nature as well as human society. 3

4. Causes of Global Warming: I am melting!!! 4

5. Causes of Global Warming: Population growth Mining Activities 5

6. Causes of Global Warming: Burning fossil fuels: Carbon dioxide absorbs infra-red energy emitted from the earth’s surface, preventing it from returning to space. Auto mobiles Electricity generation Deforestation of rainforests: Releases large amounts of carbon, as well as reducing the amount of carbon capture on the plane 6

7. Causes of Global Warming: Water vapor Aerosols present in the Atmosphere 7

8. Effects of Global Warming: Sea levels and Acidification Sea level rises 12 inches every year Melting polar ice in both the regions Global sea level rose about 8 inches Acidity of the oceans has increased about 25% 8

9. Effects of Global Warming: Animals and Plants: Species are moving to higher altitude. Change in migratory animals and insects. Expanding range of diseases killing off trees. 9

10. Effects of Global Warming: Social Effects:  Carbon-di-oxide effecting the growth of plants.  Hampers human health.  Severe crop failure. 10

11. Prevention Planting trees. Using green-transportation. Choosing renewable energy. Replacing light bulbs with compact fluorescent bulbs. Switching off electric appliance. Using solar energy. 11

12. Prevention 12

13. Prevention 13

14. Conclusion It is high time to take care of our planet and get rid of “Global Warming” 14
