Summary

Notes

• Story about end of the century: grim
• We are failing .. .we might need to do something radical
• Will it make it all much worse? or undo what we have done?

• What is it?
• Is it an option?
• What if it goes wrong?

• Focus on Stratospheric Aerosol Injection
• Basic on climate: energy comes in and is trapped = like a blanket in your bed
• Albedo: 29% already
• Pinatubo
• Sulfure dioxide: nasty smelling
• Veils
• We could imitate this: easy? cheap?
• Side effects
• Change rainfall / famine
• Heated up the stratosphere (pinatubo) + damage to ozone layer
• Delay the switch to carbon neutral economy / acidification of oceans will continue
• Termination problem: we add CO2 + we block = time bomb. If we stop ... things will happen very quickly.
• Best case: it buys us time
• Scary / not a solution / might be an excuse ... very controversial so we stopped investigating ... short sighted
• We are already are doing geoengineering in a sense
• Hopefully we don't need it ... but if we do, we better have done the science ... or a PANICKING humanity might act in urgency
