1. Global Warming: Causes and Effects A presentation by: Emily Swain Steve Townsend Amanda Washington Keenan Whitesides Linsdey Williams

3. Patterned increases and decreases throughout the yearYear vs. Average Global Temperature 1880 1940 1860 1960 1980 2000 1900 1920 http://www.bbc.co.uk/schools/gcsebitesize/science/images/global_temp_graph.gif

5. Global Warming and Cooling is a cycle.

7. The average temperature is rapidly accelerating.http://www.bbc.co.uk/schools/gcsebitesize/science/images/global_temp_graph.gif 1960 1940 1980 1920 2000 1900 1880 1860

10. Those Greenhouse Gases are released when humans burn fossil fuels – fuels containing Carbon.http://www.lilithgallery.com/articles/environmental/images/Global-Warming-02.jpg

13. Waste from farm animals (like cows) releases large amounts of methane into the atmosphere.

14. Deforestation

17. There will also be an abundance of freshwater from caps in oceans

19. We need to take the following steps to insure minimal disruption:

20. Invest in clean energy – no more fossil fuels

21. Fossil fuels include Coal, Oil, Natural Gas.

22. Some alternatives are: Solar Power, Wind Power, Geothermal Power, Hydroelectric Power, Biomass Powerhttp://www.consumerenergyreport.com/wp-content/uploads/2009/09/RenewableEnergy11.jpg http://www.thegreenbubble.org/images/renewable-energy.gif

24. Effective, yet currently expensive.http://www.conserve-energy-future.com/Images/Solar_Power.jpg http://www.alternative-energy-news.info/images/technical/solar-power.jpg

26. Effective, yet currently expensive.http://thecostaricanews.com/wp-content/uploads/2009/10/windpower.jpg http://www.alternative-energy-news.info/images/technical/wind-power.jpg

28. Effective, yet currently very expensive to set up and use efficiently.http://visual.merriam-webster.com/images/energy/geothermal-fossil-energy/production-electricity-from-geothermal-energy.jpg

30. Effective, yet currently expensive.

31. Very disruptive to water ecosystems.http://www.alternative-energy-news.info/images/technical/hydro-power.jpg

33. Not as effective, also very dangerous.

34. Disrupts natural habitats in large amounts.http://www.energy.ca.gov/biomass/images/biomass_graphic.jpg

36. It is because of humans that the average global temperatures are rising.

37. The only way to stop the increase is to:

38. Change the way that we are living

39. Use clean energy

40. Cease the burning of fossil fuelshttp://www.stuffintheair.com/images/global-warming-effect-21304194.jpg
