Episode notes
Climate Models Show Faster Near-Term Warming
- Global warming is accelerating faster than recent trends indicate.
- Researchers improved climate models using greenhouse gas, ocean heat, and ice-sheet dynamics to show faster warming and higher near-term risk.
Use Privacy-Preserving Cryptographic Age Verification
- Implement age verification that preserves privacy using cryptographic tokens and decentralized identifiers.
- System76 proposes secure tokens and public key infrastructure so age is proven without revealing identity details.
Tech Job Market Worse Than Previous Recessions
- Tech employment conditions are worse than in 2008 and 2020 due to aggressive cuts and talent oversupply.
- Post links pandemic hiring surge and remote-work geography to a larger candidate pool and prolonged weak recovery.
