1. Global Climate Change Fact & Fiction

2. True - False The “Greenhouse Effect” is GOOD for life on planet Earth

3. Question What exactly are fossil fuels?

4. Word Game Put these words into two appropriate groups: Infrared rays (IR)* Ozone Visible light* CO 2 Ultra-violet* Greenhouse Eff.

5. BIG QUESTION What are the scientific FACTS regarding the Greenhouse Effect/Global Climate change????

6. FACT #1 The Carbon Cycle (See board)  Humans DO engage in activities which affect the atmospherics CO 2 through combustion of Fossil fuels, deforestation, lowering rates of photosynthesis  Not in dispute!!

7. Fact #2 Greenhouse Effect  Verified by: –Actual greenhouses –Hot car/ cold day phenomenon –Greenhouse gasses on Earth and other planets  Not in dispute!!

8. Fact #3 Does life on planet Earth benefit from the GE? Would life on planet Earth benefit from an enhanced GE?

9. Fact #4 IF carbon dioxide levels rise, more heat (IR) will be trapped  Not in dispute!

10. Fact #5 Carbon dioxide levels ARE rising…..  therefore…………..  Not in dispute

11. Hawaii Data: Global CO2 levels!

12. More heat IS being trapped

13. Fact #6 Carbon dioxide is increasing at a RATE higher than any natural cycle ever recorded Current levels of CO 2 are higher than in all of recorded history

14. Long term Ice Core Data

15. Fact #7 Climates are determined by atmospheric and oceanic convection currents  Not in dispute!

16. Fact #8 If you increased the amount of IR (heat) being trapped, you will alter the convection currents  Not in dispute!

17. Uncertainties #1-4 How MUCH will the convection currents be altered? What areas of the globe will be hotter/colder/wetter/drier? How MUCH of the ice sheets will melt? How HIGH will sea level rise due to thermal expansion & melting ice?

18. Fact #9 The global climate IS changing! And this is called the THEORY of Global Climate Change because the evidence is so diverse….. For example, area of Arctic Ice cap:

19. is the increased greenhouse effect; I'd bet the mortgage it Mark Serreze, NSIDC ARCTIC SEA ICE EXTENT - SEPTEMBER TREND, 1978-2005 The area covered by sea ice

20. Data: Changes in Flowering Dates

21. Data: Mismatch of Bird Nesting & Food Availability

22. We have “Early Warning Signs”

23. Uncertainties #5 - 8 What can individuals do? What can our government do? Which actions are BEST to take? What are the consequences of inaction???
