4. GLOBAL WARMING

5. Introduction

6. CAUSES OF GLOBAL WARMING Natural Man-made

7. Natural Climate change The rotation of the earth Volcanoes Change in ocean currents Solar cycles and sunspots

8. Humancauses Power plants 2.Cars 3.Fertilizers 4.Deforestation 5.Ozone depletion

10. GREENHOUSE EFFECT The greenhouse effect occurs when certain gases in the atmosphere trap infrared radiation. This effect makes the planet warmer. When their is more greenhouse gases in the air, the air holds more heat. This is why more greenhouse gases cause global warming.

14. Methane

15. CFCs

17. Deforestation and plant burning (20-25%).Average time in the troposphere is 50-500 years.

18. LAYERS OF ATMOSPHERE

27. EFFECTS OF GLOBAL WARMING Climate change on human society Effects on plants and animals Effects on human being and health Effects on sea level Heat waves

28. EFFECTS OF GLOBAL WARMING 6. Ozone becomes harmful 7. Economic consequences 8. Disappearance of coral reefs 9. More killer storms 10.Effect on agriculture

30. The protocol was developed under the UNFCCC – the United Nations Framework Convention on Climate Change .

32. FACTS ON GLOBAL WARMING

33. What will happen if global warming is allowed to continue ?

34. If worlds warms by : 10c : climate will become intolerable

35. 20c : Ocean life in danger

36. 30c : heat waves fatalities

37. 40c : great cities wash away

38. 50c : civilization collapses

39. 60C : Mass extinction occurs
