  • 1. Topic 6 Impact and Responses to Climate Change Text page 109 - 119
  • 2. Essential Questions Definitions Learning outcomes A. What are the impact of climate change to humans? B. How do countries prepare for the impact brought about by climate change? (LDQ - PEEL) - Climate change has impacted the natural environment and human lives - Strategies can be implemented to reduce human induced climate change and its impact. - Variable weather and climate continues to provide a challenge to humans due to the negative impact it can bring to the natural environment and human lives. - Explain the impact of climate change to the environment and human lives. - Describe how countries/govt have responded to climate change issues
  • 3. 6A. What are the impact of climate change to humans? 1. Sea level rise 2. Extreme weather events 3. Diseases spread 4. Growing season affected Sijie Eats Dried Guava
  • 4. 1. Sea level rise • Steady increase in sea level height • Higher temperatures cause ▫ Melting of glaciers (ice) ▫ Sea and oceans to expand • Threatens low-lying islands and coasts eg Maldives
  • 5. 2. Extreme weather events • Refers to severe and rare weather phenomenon = results in economic losses and loss of lives • Higher frequency due to higher land and sea surface temperatures ▫ Results in greater amount of water vapor and heat • Eg: Heat waves, floods, droughts, cyclones
  • 6. 3. Diseases spreading • Increased temperatures and rainfall helps insects to thrive • May spread infectious insect-borne disease (transmit to humans/animals) • Eg Mosquites breed easier with heavy rainfall (Spread of malaria and dengue) • Diseases also spreads to new places because climate of a place changes
  • 7. 4. Growing season affected • Higher temperatures may result in longer or shorter growing season for crops • GOOD: Blackberries (can grow in UK now as temperature increased) • BAD: Applies and Cherries (Production reduced in Yunnan as they need cool weather conditions)
  • 8. 6B. How do countries prepare for the impact brought about by climate change? 1. International responses: Kyoto Protocol and Copenhagen Conference 2.National responses: Individual countries eg Singapore and India (PEEL)
  • 9. International level – United National efforts Definition Successes Limitations KyotoProtocol - Reduced green- house gas emission - Many countries met or exceed target to reduce greenhouse gas - Countries carried out emission reduction projects - Some countries didn’t achieve targets - Some countries didn’t sign treaty CopenhagenConference - Improve measures for Kyoto Protocol - Cap increases in global mean maximum temperature within 2 degrees celsius - Funds provided to reduce greenhouse gas emission - Targets not met by many countries
  • 10. 6B. How do countries prepare for the impact brought about by climate change? 1. International responses: Kyoto Protocol and Copenhagen Conference 2.National responses: Individual countries eg Singapore and India (PEEL)
  • 11. Point Explain Example Limitation
  • 12. Format: 6 marks (usually last question) Sample questions 1) With reference to examples, assess the effectiveness of how Singapore has reduced the greenhouse gas emissions. 2) Evaluate the extent that India should take responsibilities to reduce the emission of greenhouse gases. Text page 115
  • 13. With reference to example, assess the effectiveness of how locals protect tourist areas. L3/6 : L3/5 with well elaborated CONCLUSION In conclusion, locals are largely effective in protection of the tourist areas. However they will need to improve on their labour skills in conservation and preservation of the environment so that they are capable to manage the tourism impacts successfully. Groups (P) Strengths (E) Examples (E) Limitations (L) Locals – A local communi ty is a group of people living in the same territory. Community based tourism makes locals a priority in employment and business opportunities. They also benefit economically from tourism. In Java (Indonesia), the Candirejo village had new jobs and businesses due to tourism. There were 63 new jobs, 5 new business as well as 12.5 % increase in income from 2001 to 2003. The locals may not have enough skilled labour such as managers and consultants that can successfully help to manage the impact of tourism. Therefore, they may need to seek help of NGOs to provide training.
  • 14. Marks allocation •Level 1: 0 – 2 marks eg L1/1 , L1/2 •Level 2: 3 – 4 marks eg L2/3 , L2/4 •Level 3: 5 – 6 marks eg L3/5 , L3/6
  • 15. Level 1: 0 – 2 marks • Simple description of strengths and limitations • One sided answer • No example given • L1/1 : ONE strength or ONE limitation of ONE group • L1/2 : ONE strength or ONE limitation of TWO groups
  • 16. Level 2: 3 – 4 marks •Detailed description of strengths and limitations •Two sided answer •Examples are given •L2/4 : ONE strength & ONE limitation of TWO groups with TWO examples
  • 17. Level 3: 5 – 6 marks • Very detailed description of strengths and limitations • Two sided answer • Examples are given • L3/5 : ONE strength & ONE limitation of TWO groups with TWO examples • L3/6 : L3/5 with well elaborated CONCLUSION
  • 18. Homework 6 1) With reference to examples, assess the effectiveness of how Singapore has reduced the greenhouse gas emissions. [6] 2) Evaluate the extent that India should take responsibilities to reduce the emission of greenhouse gases. [6]
