Episode notes
U.S. Government Pullback From IPCC
- The U.S. withdrawal from IPCC has materially reduced government scientist participation this cycle.
- About 60 U.S. scientists still participate via academia and philanthropy funding for travel and meeting costs.
Poverty Amplifies Climate Damage
- The worst climate damages occur when high warming coincides with poverty and low adaptive capacity.
- Socioeconomic pathways matter as much as physical warming for human impacts.
Treat Geoengineering As A Strictly Bounded Band‑Aid
- Solar‑radiation modification (SRM) is a band-aid: it cools but doesn't remove CO2 and risks long-term dependence.
- Limit SRM to replacing current aerosol masking to avoid unaffordable termination costs and addiction.
