Episode notes
Consider Alternative Climate Solutions
- Decarbonization progress is too slow to meet climate targets.
- Consider carbon capture or solar geoengineering as pragmatic approaches.
Climate Targets Are Political
- Scientific bodies like the IPCC don't set climate targets, politicians do.
- Scientists inform about consequences, but targets involve political and economic trade-offs.
Solar Geoengineering: A Relatively Cheap Fix
- Solar geoengineering, using aerosols, offers a relatively cheap way to cool the planet.
- Deploying this technology could be achieved with a fleet of specialized aircraft.
