Global warming refers to the increase in Earth's average surface temperature primarily due to greenhouse gases such as carbon dioxide and methane, which have surged since the Industrial Revolution. Key contributors include fossil fuel pollution, deforestation, and population growth, leading to severe impacts like extreme weather, rising sea levels, and biodiversity loss. The document emphasizes the urgency of taking action to mitigate global warming through individual and collective efforts.

1. GLOBAL WARMING

3. Increase in the average measured temperature of the Earth's surface air and oceans

4. GLOBAL WARMING is the increase in the average measured temperature of the Earth’s Near-surface air and oceans since the mid-twentieth century and its projected continuation

5. How Global Warming Works Greenhouse gases Fossil fuels (coal, oil, natural gas) Carbon Dioxide (CO 2 )

6. Green house effect Changes in solar luminosity Volcanic eruptions variation of Earth’s orbit around the Sun FACTORS RESPONSIBLE FOR EARTH’S CLIMATE CHANGES:

7. It is the process by which absorption and emission of infrared radiation by atmospheric gases takes place which warm a planet’s lower atmosphere and surface.

8. Greenhouse Effect

9. Water vapour Carbondioxide (CO2) Methane (CH4) Ozone (O3) Nitrous oxide (N2O) Cloro floro carbons(CFC’s)

10. Water vapour 36-70% Carbondioxide 9-26% Methane 4-9% Ozone 3-7% Composition of green house gases present in the atmosphere causing global warming

11. Global Atmospheric Concentration of CO 2

13. Atmospheric concentrations of CO2 and CH4 have increased By 31% and 149% respectively since the beginning of industrial revolution In the mid-1700’s. Mean warming effect of green house gases is about 33 degrees centigrade’s more. Actual surface temperature -15 degrees. Present surface temperature 18 degrees. Further rise of 1.1—6.4degrees C during 21 st cen. FEW FACTS:

14. Atmospheric Concentration of CO2 Present concentration:  385ppm by volume Expected concentration by the year 2100:  541-970ppm by volume (If the usage of fossil fuels continues like the present trend)

16. CAUSES OF GLOBAL WARMING

17. Pollution from coal, natural gas, and oil

18. CO 2 from airplanes & vehicles

19. POPULATION INCREASE

20. DEFORESTATION

22. Melting of glaciers

23. Polar Bear Extinction

24. Warmer waters and more hurricanes

25. Increased probability and intensity of droughts and heat waves

26. Increased Temperature

27. Melting Polar ice caps

28. ANTARCTICA – losing ice faster..!!!!!! BEFORE NOW

32. Major CONSEQUENCE of global warming is ………….

34. At some places, it

36. At others……

38. SOMEWHERE it’s tooo…….ooo

39. HOT

40. WHEREAS At others tooo…..

41. COLD

43. Its all because of

44. GLOBAL WARMING

45. Is it impossible to solve this problem

46. DON’T CRY

48. It’s NOT too LATE ACT NOW!!!!

49. WE CAN STOP GLOBAL WARMING!

51. Turn off your computer or the TV when you’re not using it.

52. Turn off the lights when you leave a room.

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

54. Unplug unused electronics

55. Plant trees.

56. Recycle.

57. Drive LESS, drive SMART Use a bicycle or bus

58. Wind Power

59. Solar Power

60. Fuel efficient cars

61. SAVE THE EARTH Before its too late

62. Think Globally Act Locally
