2. air we cant see it…

3. air nothing? ….but is

4. air is not just emptiness

5. air is an amazing mix of gases

6. air is a amazing mix of gases! very

7. gases in the gases in the come from come from the we share theair life

18. w h a t i s a i r? we share the air

19. w h a t i s a i r? we share the air nitrogen oxygen carbon dioxide methane & other trace gases

20. w h a t i s a i r? we share the air … the air itself is a biological product … a result of active exchange of gases with living organisms. The air is a protective skin, a warming blanket, an exchange & water circulation medium…

21. w h a t i s a i r? we share the air …the composition of the air seems to violate the ordinary rules of equilibrium chemistry. James Lovelock GAIA – The practical science of planetary medicine

22. w h a t i s a i r? we share the air nitrogen 79%

23. w h a t i s a i r? we share the air nitrogen maintains our atmospheric pressure nitrogen 79%

24. w h a t i s a i r? we share the air oxygen 21%

25. w h a t i s a i r? we share the air oxygen 21% oxygen allows plants & animals to get energy from food

26. w h a t i s a i r? we share the air carbon dioxide 280 ppm (pre-industrial)

27. why is CO 2 so important? we share the air carbon dioxide 280 ppm (pre-industrial) CO 2 allows photosynthesis & keeps planetary temperature stable

28. we share the air carbon dioxide 370 ppm (now – up by 1/3) why is CO 2 so important? CO 2 was very common when life first started 3.5 billion years ago

29. we share the air carbon dioxide 370 ppm (now – up by 1/3) CO 2 was very common when life first started 3.5 billion years ago where has the CO 2 gone?

30. we share the air where has the CO 2 gone?

31. we share the air where has the CO 2 gone?

32. we share the air over billions of years CO 2 extracted from atmosphere carbon stored as chalk, limestone & fossil fuels result – an atmosphere for life to evolve and prosper. where has the CO 2 gone?

33. we share the air CO 2 extraction today

34. we share the air CO 2 extraction today

35. we share the air CO 2 extraction today

36. we share the air n a t u r e c a nt c o p e Oceans & forests cant absorb all the CO 2 from our cars, planes, homes & factories.

37. we share the air n a t u r e c a nt c o p e Thats why CO 2 is increasing in the atmosphere so fast

38. we share the air n a t u r e c a nt c o p e …and the earth is now warming

39. we share the air climate change is happening Glacier in Peru's Cordillera Blanca range, 1980 Photo: Bryan Lynas Same place, 2002 Photo:Tim Helweg-Larsen, 2002

40. we share the air Fish barbecue in Tuvalu, Pacific. Photo: Mark Lynas climate change is happening

41. we share the air Fish barbecue in Tuvalu, Pacific. Photo: Mark Lynas climate change is happening Global climate, even in fifty years time, may be warmer than the earth has experienced in the past 12 million years….. changes of this speed and magnitude are unprecedented to our knowledge, aside from large meteorite impacts. * Peter Barrett, Antarctic Research Centre, New Zealand

42. we share the air s o w h a t c a n w e d o?

43. we share the air support a low-carbon future s o w h a t c a n w e d o?

44. we share the air s o w h a t c a n w e d o? …and leave them a living planet

45. we share the air it depends who you are …and leave them a living planet s o w h a t c a n w e d o?
