Transcript

  • 1. + 3 Express Pure Geog: Types of Climate 9h April 2012 Climate changes in the last 200 Years Arman Alluwie TP2 SHSS
  • 2. + 2 What did we learn last lesson?  Consolidated learning on the types of climates  Linked up climatic patterns with elements of weather  Revisited Monsoon Winds  Feedback from Observation  Draw lessons from personal experiences to understand climate  Return of Marked WorksheetsArman Alluwie TP2 SHSS
  • 3. + 3 Geography Class Test: CA2  11th of April 2012  Wednesday, Double Period  Topics Tested  Chapter 6 Elements of Weather (page 87- 108)  part of Chapter 7 Types of Climate (page 117)Arman Alluwie TP2 SHSS
  • 4. + 4 Lesson Objectives  By the end of the week, we would have  discussed the climate changes in the last 200 yearsArman Alluwie TP2 SHSS
  • 5. + 5 An Inconvenient Truth: TrailerArman Alluwie TP2 SHSS
  • 6. + 6 Climate Change: What do we know? complete this page of the handoutArman Alluwie TP2 SHSS
  • 7. + 7 Climate Change: What do we know? complete this page of the handoutArman Alluwie TP2 SHSS
  • 8. + 8 Climate Change: A Quick Disclaimer  Climate change is an undergoing study  facts and figures are highly debated amongst scientists and interest groups  no common consensus on a governing authority on climate change  Intergovernmental Panel on Climate Change  requires the benefit of timeArman Alluwie TP2 SHSS
  • 9. + 9 Climate Change  is a shift in the average weather conditions that a region experiences over a long period of time  cold stages (glacial periods)  warm stages (interglacial periods)  So what’s the concern?  speed of temperature change has increased  coincides with dramatic increase in carbon dioxide levels pg 118 of textbookArman Alluwie TP2 SHSS
  • 10. + 10 Enhanced Greenhouse Effect: Revising the Greenhouse Effect you may have problems with the infrared radiation portion complete this page of the handoutArman Alluwie TP2 SHSS
  • 11. + 11 I J B M C A D K F E L H G NArman Alluwie TP2 SHSS
  • 12. + 12 Enhanced Greenhouse Effect: Revising the Greenhouse Effect  natural process whereby greenhouse gases absorb heat from the Sun’s rays and trap it in the atmosphere  “transparent blanket”: allowing light to pass through but trapping heat  greenhouse gases  carbon dioxide, water vapour, nitrous oxides and methane  average temperature of 15°CArman Alluwie TP2 SHSS
  • 13. + 13 Enhanced Greenhouse Effect  More greenhouse gases released and trapped  Global Warming  Rise in Earth’s average global temperature CH4 by 150% CO2 by 30% Nitrous Oxides  by 15% Industrial RevolutionArmanAlluwie TP2 SHSS
  • 14. + 14 Enhanced Greenhouse Effect: Causes 1. Industrial Activities 2. Large Scale Deforestation 3. Agricultural ActivitiesArman Alluwie TP2 SHSS
  • 15. + 15 Enhanced Greenhouse Effect: Industrial Activities http://www.youtube.com/watch?v=oWlcqdPJEPgArman Alluwie TP2 SHSS
  • 16. + 16 Enhanced Greenhouse Effect: Industrial Activities http://videos.howstuffworks.com/discovery/31565- massive-engines-bucket-wheel-excavator-video.htmArman Alluwie TP2 SHSS
  • 17. + 17 Enhanced Greenhouse Effect: Industrial Activities  advancements in technology has increased the scale of human activities   in the use of fossil fuels in vehicles, factories and power plants  interconnectedness has increase the spatial impact of human activities  how do you get your Norwegian Salmon?Arman Alluwie TP2 SHSS
  • 18. + 18 Enhanced Greenhouse Effect: Large Scale Deforestation  reduced the amount of vegetation cover  less carbon dioxide is absorbed from the atmosphere  cleared for timber and mining, to create land for other activities such as agriculture and urban development 1997 Haze Hell over AsiaArman Alluwie TP2 SHSS
  • 19. + 19 Enhanced Greenhouse Effect: Agricultural Activities  Not something new however the food industry brings some concerns … http://vimeo.com/8812686Arman Alluwie TP2 SHSS
  • 20. + 20 Checkpoint 1: Enhanced Greenhouse Effect  More greenhouse gases released and trapped  Global Warming  Rise in Earth’s average global temperature CH4 by 150% CO2 by 30% Nitrous Oxides  by 15% Industrial RevolutionArmanAlluwie TP2 SHSS
  • 21. + 21 Enhanced Greenhouse Effect: Causes 1. Industrial Activities 2. Large Scale Deforestation 3. Agricultural ActivitiesArman Alluwie TP2 SHSS
  • 22. + 22 Enhanced Greenhouse Effect: Can we stop?Arman Alluwie TP2 SHSS
  • 23. + 23 Effects of Climate Change 1. Melting Ice and Rising Sea Levels 2. Extreme Weather Conditions 1. Severe Storms 2. Heat Waves and Droughts 3. Impact on Plants and AnimalsArman Alluwie TP2 SHSS

  • 25. + 25Arman Alluwie TP2 SHSS http://www.youtube.com/watch?v=6hFxG-8I0Go
  • 26. + 26 Melting Ice and Rising Sea Levels  glaciers are retreating and the amount of ice cover has decreased in the polar regions  melting of this frozen stores of water has caused sea levels to rise  low-lying coastal countries are especially vulnerable to rising sea levelsArman Alluwie TP2 SHSS
  • 27. + 27 Extreme Weather Conditions  higher global temperatures increase evaporation rates resulting in higher relative humidity   in rainfall  warmer ocean temperatures cause more intense (both frequency and strength) tropical storms  September- October 2005: 3 Major HurricanesArman Alluwie TP2 SHSS
