1. ? WHAT IS

2. it’s MORE than a NUMBER...

3. SCIENCE it’s about…

4. it’s a clear limit

5. CLIMATE THAT TELLS US WHAT’S SAFE FOR OUR

6. What do we know about climate change?

7. THE GREENHOUSE EFFECT 1. CO2 and other greenhouse gases trap heat from the sun in our atmosphere.

8. Before the Industrial Revolution, for thousands of years, the amount of carbon in the atmosphere was at 287ppm

9. Now, after three centuries of burning coal, oil, and gas, we're at 390ppm – that’s above any levels we’ve seen in recorded history.

10. 2. We also know that CO2 influences global temperature CO2 in PPM GLOBAL TEMPERATURE Years ago Parts per Million CO2 TODAY: 390ppm 550ppm? More? EARLY 1900S LAST ICE AGE Where we’ll be mid-century if we keep this up look how the temperature line follows CO2 concentrations throughout history

11. 3. And now we’re seeing the results - we can see that measurable, recorded impacts are happening now all around us. Chapare, Bolivia

18. OCEANS ARE ACIDIFYING

19. Coral reefs are bleaching

20. WEATHER IS BECOMING MORE EXTREME

21. Australia suffers worst drought in 1,000 years “ ” - Guardian UK, Nov 7, 2008

22. U.S. dealing with Katrina’s wrath as death toll soars. “ ” - International Herald Tribune, August 31, 2005

23. MAJOR FLOODS PER DECADE number of major floods per decade

24. Small islands are sinking or eroding

25. “ Rapid Warming’ Spreads Havoc in Canada’s Forests. “ ” - Washington Post, March 1, 2006

26. Australia fires spark calls for CLIMATE ACTION “ ” - Washington Post, March 1, 2006

27. The most startling evidence yet…

28. is the MELTING OF THE ARCTIC. New predictions Satellite observations Mean IPCC prediction Most likely change (melt) IPCC range Actual observed melting it has melted nearly 80 YEARS ahead of when scientists predicted YEAR % change in ice cover

29. CO2 IN THE ATMOSPHERE WE’RE HERE: 390 WE NEED TO BE HERE: 350 PARTS PER MILLION CO2 YEAR

30. How do we know all this?

31. The largest research project in history: I n 1988, the IPCC was created to “provide the decision-makers and others interested in climate change with an objective source of information about climate change”

32. NEW REPORTS EVERY 4 YEARS SCIENTISTS

33. WON THE NOBEL PRIZE IN 2007 WITH AL GORE

34. We’ve warmed our planet more than 1 degree F/ .07 degrees C and are already observing major impacts and changes in our climate.

35. Do we really want to see what happens if we keep going? We will face increasingly severe impacts like…

36. the disappearance of SMALL ISLANDS

37. severely impacted LOCAL ECONOMIES

38. The most comprehensive review ever carried out on the economics of climate change warns that global warming could inflict worldwide disruption as great as that caused by the two World Wars and the Great Depression. “ ” - Environmental News Service STERN REVIEW, 2006

39. The world has never faced such a predictably massive threat to food production as that posed by the melting mountain glaciers of Asia “ ” - Lester Brown, Earth Policy Institute, Author of Plan B THE DISRUPTION OF FOOD PRODUCTION

40. Climate change could force 1 BILLION from their homes by 2050. “ ” - April 30, 2008, The Independent. A HUMAN RIGHTS CRISIS AND INSTABILITY

41. THAT’S WHY WE HAVE TO ACT NOW.

42. “ If humanity wishes to preserve a planet similar to that on which civilization developed and to which life on Earth is adapted, paleoclimate evidence and ongoing climate change suggest that CO2 will need to be reduced from its current 387ppm to at most 350ppm.” - NASA climatologist Dr. James E. Hansen, 2008

43. so how do we get back to 350ppm and avoid climate catastrophe?

44. IT’S DIFFICULT BUT NOT IMPOSSIBLE IF WE START NOW.

45. IT MEANS PUTTING UP WIND TURBINES INSTEAD OF COAL PLANTS

46. IT MEANS PLANTING TREES INSTEAD OF CLEAR-CUTTING RAINFORESTS

47. AND IMPLEMENTING A THOUSAND DIFFERENT SOLUTIONS

48. that can create new jobs

49. And make our communities HEALTHIER

50. PARTS PER MILLION CO2 YEAR Phaseout of coal by 2030 Improved forestry and soil Reduced oil/gas use GETTING TO 350

52. BY TAKING ACTION, WE CAN CALL ON OUR LEADERS TO MAKE THESE CHANGES

53. AND PROVIDE AN EXAMPLE OF HOW OUR COMMUNITIES COULD BE IN A WORLD AT 350PPM
