The Greenhouse Effect and Global Warming

1. The Greenhouse Effect and Global Warming Climate Change Facts, Opinions, Debate and Action

2. Objectives • MUST: recall some of the key facts of The Greenhouse Effect and Global warming • SHOULD: be able to describe a number of ways of dealing with CO2 emissions • COULD: be able to explain the challenges for society in tackling the issue of global warming and it’s potential effects

3. Facts

4. Facts • CO2 is a greenhouse gas (the more there is, the more it traps Solar Energy)

5. Facts • CO2 is a greenhouse gas (the more there is, the more it traps Solar Energy) • Human Activities, mostly involving fuel use, add large quantities of CO2 to the atmosphere

6. Facts • CO2 is a greenhouse gas (the more there is, the more it traps Solar Energy) • Human Activities, mostly involving fuel use, add large quantities of CO2 to the atmosphere • CO2 levels are increasing

7. Facts • CO2 is a greenhouse gas (the more there is, the more it traps Solar Energy) • Human Activities, mostly involving fuel use, add large quantities of CO2 to the atmosphere • CO2 levels are increasing • Average Global Temperatures are increasing

8. Average Temperatures

9. Temperatures

10. Levels of CO2 - Recent

11. Levels of CO2 - Historical

12. Is CO2 causing Global Warming?

13. Is CO2 Causing Global Warming?

14. Maybe, Maybe not?

15. Opinions or Arguments from Authority?

16. Opinions or Arguments from Authority? • The Rise in CO2 levels is causing Global Warming

17. Opinions or Arguments from Authority? • The Rise in CO2 levels is causing Global Warming • Global Warming is responsible for Climate Change

18. Opinions or Arguments from Authority? • The Rise in CO2 levels is causing Global Warming • Global Warming is responsible for Climate Change • Climate Change is responsible for the extreme weather in recent years

19. Opinions or Arguments from Authority? • The Rise in CO2 levels is causing Global Warming • Global Warming is responsible for Climate Change • Climate Change is responsible for the extreme weather in recent years • Climate Change will.....

20. What can be done? Should something be done?

21. What can Scientists do? • Debate and Discuss • Use Arguments from Authority • Find ways to reduce CO2: • Emissions - Energy Use • Containing and Reducing Atmospheric CO2

22. How to Reduce CO2 • Cut Emissions - Energy Efficiency, Restrictions on Energy use (Taxes on Cars?) • Carbon Neutral – Plants trees, plants, to remove CO2

23. Arguments • Deductive Arguments = reasoning from the general to the specific • Inductive Arguments = reasoning from specific observations to a broader generalisation • Arguments from Authority = Opinion offered by an expert on the basis of their knowledge... • Arguments from Analogy = Reasoning based on percived similarities.... • Casual Arguments = These claim that something has happened as a direct result of something else occurring previously....

24. Climate Change – What can be done?

25. Tackling Climate Change • Carbon Footprint • Carbon Neutral • Energy Efficiency

26. Tackling Climate Change • Reduce Fuel Use • Increase Energy Efficiency • Reducing Deforestation / Planting more Trees • Carbon Capture and Storage

27. Problems Associated with Tackling Climate Change • Costly – Economic Slowdown • Personal Demands and Comforts • Demands for raw materials and expanding population
