26. Impacts: extreme weather events

27. Economic impacts -- especially from extreme weather “2005 Atlantic hurricane season has clearly been the most active season on record” www.pewclimate.org/hurricanes.cfm#5

28. Impacts: in parts of the world -- less rain, less crops

31. Climate change used to justify…BIG DAMS • Ecological/social damage from flooding • Decimated fish stocks • Especially impacts rural politically disempowered • (Often does cause climate change)

32. NUCLEAR • Expensive • Waste deadly for at least 250,000 years • We can’t figure out how to dispose of waste • Unavoidable weapons linkages

33. Global warming is only a tiny part of the energy/ecology/society story… • One large shopping mall (average consumption): 10 Megawatt • Pak Mun Dam (average production): 40 Megawatt • Fish stocks decimated • 10 years of protest, 5000 villagers • Communities forcefully relocated

34. Are there alternatives? … yes… • Save energy • Use clean (renewable) energy

35. (Real) Buddhist values • Moderation / simplicity • Emphasis on “being” rather than “having”
