Impacts: flooding & sea-level rise

Apart from CO2 reduction, adaptation is needed…
Impacts: extreme weather events
Economic impacts -- especially from extreme weather
“2005 Atlantic hurricane season has clearly been the most active season on record”

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

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)
NUCLEAR
• Expensive
• Waste deadly for at least
250,000 years
• We can’t figure out how to
dispose of waste
• Unavoidable weapons
linkages
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
Are there alternatives? … yes…
• Save energy
• Use clean (renewable) energy
(Real) Buddhist values
• Moderation / simplicity
• Emphasis on “being” rather
than “having”

Korat Waste to Energy - biogas
• Uses waste water from cassava to make methane
• Produces gas for all factory heat (30 MW thermal) + 3 MW of
electricity
• Earns high market returns
• Developer estimates 300 MW from waste water + 800 MW
from wet cake
