Transcript

  • 1. climate changeintro + causes
  • 2. what is happening to our climate?
  • 3. where’s the ice?
  • 4. where’s the ice?
  • 5. where’s the ice?
  • 6. WHY is this happening?
  • 7. • Define “climate change” • Explain natural causes of climate change • Explain human causes of climate change by the end 
 of the lesson
  • 8. quiz! 1
  • 9. qns 1 Climate Change is the same as Global Warming 5:20 True? False?
  • 10. qns 1 Climate Change is the same as Global Warming 5:20 True? False? Climate change = climate patterns changing. It’s not just warming. Includes cooling. Global warming = increase in temperature ONLY.
  • 11. qns 2 Climate Change is caused by humans only. True? False?
  • 12. qns 2 Climate Change is caused by humans only. True? False? There are natural causes to climate change.
  • 13. qns 3 Climate Change is a recent phenomenon True? False?
  • 14. qns 3 Climate Change is a recent phenomenon True? False? Earth Climate has been changing as a cycle naturally for millions of years.
  • 15. Temperature of the world has been changing throughout history naturally.
  • 16. There were times where Earth was cooler than today = ice age
  • 17. qns 4 Since there has been climate change throughout history, there is nothing to worry. True? False?
  • 18. qns 4 Since there has been climate change throughout history, there is nothing to worry. True? False? The recent changes since 1881 is more significant than what happened in history.
  • 19. Climate Change has been within a small temperature range
  • 20. Climate Change has been within a small temperature range But since 1881, the increase is higher than what happened in history
  • 21. key concepts 2
  • 22. climate change = changes / variations in global climate patterns in the long term
  • 23. climate change = changes / variations in global climate patterns in the long term = not just changes in average temperature. Eg: Changes in when the seasons occur 
 is also climate change!
  • 24. climate change = changes / variations in global climate patterns in the long term
  • 25. climate change = changes / variations in global climate patterns in the long term onewayithappens… global warming INCREASE in global temp. after a long period of time
  • 26. climate change = changes / variations in global climate patterns in the long term onewayithappens… global warming INCREASE in global temp. after a long period of time global cooling DECREASE in global temp. after a long period of time one w ay it happens…
  • 27. greenhouse effect NATURAL effect of greenhouse gases trapping energy from the sun to warm the Earth.
  • 28. greenhouse effect But if we…..
  • 29. greenhouse effect But if we….. + Greenhouse Gases
  • 30. greenhouse effect But if we….. + Greenhouse Gases + Greenhouse Gases
  • 31. greenhouse effect But if we….. + Greenhouse Gases + Greenhouse Gases + Greenhouse Gases
  • 32. greenhouse effect But if we….. + Greenhouse Gases + Greenhouse Gases + Greenhouse Gases + Greenhouse Gases
  • 33. greenhouse effect But if we….. + Greenhouse Gases + Greenhouse Gases + Greenhouse Gases + Greenhouse Gases + Greenhouse Gases
  • 34. greenhouse effect But if we….. + Greenhouse Gases + Greenhouse Gases + Greenhouse Gases + Greenhouse Gases + Greenhouse Gases + Greenhouse Gases
  • 35. greenhouse effect But if we….. + Greenhouse Gases + Greenhouse Gases + Greenhouse Gases + Greenhouse Gases + Greenhouse Gases + Greenhouse Gases + Greenhouse Gases
  • 36. greenhouse effect But if we….. + Greenhouse Gases + Greenhouse Gases + Greenhouse Gases + Greenhouse Gases + Greenhouse Gases + Greenhouse Gases + Greenhouse Gases+ Greenhouse Gases
  • 37. greenhouse effect But if we….. + Greenhouse Gases + Greenhouse Gases + Greenhouse Gases + Greenhouse Gases + Greenhouse Gases + Greenhouse Gases + Greenhouse Gases+ Greenhouse Gases + Greenhouse Gases
  • 38. greenhouse effect But if we….. + Greenhouse Gases + Greenhouse Gases + Greenhouse Gases + Greenhouse Gases + Greenhouse Gases + Greenhouse Gases + Greenhouse Gases+ Greenhouse Gases + Greenhouse Gases + Greenhouse Gases
  • 39. greenhouse effect But if we….. + Greenhouse Gases + Greenhouse Gases + Greenhouse Gases + Greenhouse Gases + Greenhouse Gases + Greenhouse Gases + Greenhouse Gases+ Greenhouse Gases + Greenhouse Gases + Greenhouse Gases + Greenhouse Gases
  • 40. greenhouse effect But if we….. + Greenhouse Gases + Greenhouse Gases + Greenhouse Gases + Greenhouse Gases + Greenhouse Gases + Greenhouse Gases + Greenhouse Gases+ Greenhouse Gases + Greenhouse Gases + Greenhouse Gases + Greenhouse Gases + Greenhouse Gases
  • 41. greenhouse effect But if we….. + Greenhouse Gases + Greenhouse Gases + Greenhouse Gases + Greenhouse Gases + Greenhouse Gases + Greenhouse Gases + Greenhouse Gases+ Greenhouse Gases + Greenhouse Gases + Greenhouse Gases + Greenhouse Gases + Greenhouse Gases = ENHANCED greenhouse effect
  • 42. enhanced greenhouse effect ≠ (is not the same as) global warming
  • 43. enhanced greenhouse effect ≠ (is not the same as) global warming = more greenhouse gas 
 = more greenhouse effect 
 = more heat trapped = increase in temperature
  • 44. enhanced greenhouse effect global warming = more greenhouse gas 
 = more greenhouse effect 
 = more heat trapped = increase in temperature
  • 45. enhanced greenhouse effect global warming = more greenhouse gas 
 = more greenhouse effect 
 = more heat trapped = increase in temperature one of the causes of
  • 46. once we understand the concepts…
  • 47. how do we explain that something caused climate change?
  • 48. Let’s work backwards…
  • 49. climate change
  • 50. climate change global warming Indicates
  • 51. climate change global warming Indicates global cooling Indicates
  • 52. climate change various factors
  • 53. climate change global warming Indicates various factors
  • 54. climate change global warming Indicates global cooling Indicates various factors
  • 55. climate change global warming Indicates global cooling Indicates increase in global temp. various factors
  • 56. climate change global warming Indicates global cooling Indicates increase in global temp. decrease in global temp. various factors
  • 57. once we understand the concepts…
  • 58. causes of climate change 3
  • 59. refer to your textbook pg 98-108 fill up the story in the handout determine what are the possible reactions and outcomes try mission on coursemology
