Google Uses Computer Vision to Cut 1% of Global Warming from Contrails
John Platt explains how Google predicts atmospheric supersaturation with computer vision and agentic AI to eliminate airplane contrails.
🔬 Google's AI Scientist Started as an Attempt to Automate Kaggle — John Platt, Google Fellow
With John Platt, swyx, Alessio Fanelli · Sunday, September 27, 2026
Google Fellow John Platt discusses Google's Empirical Research Assistance (ERA) framework, an agentic AI system combining LLMs with Monte Carlo tree search to automate scientific experimentation. Platt explains how ERA grew from an attempt to automate Kaggle, the critical distinction between predictive and descriptive scientific models, and how AI is unlocking real-world climate interventions from contrail mitigation to wildfire detection.
Key takeaways
- Aviation contrails contribute roughly 1% of all human-driven global warming by trapping outgoing blackbody infrared radiation. Read more →
- AI coding tools make output fast, but skipping manual implementation prevents researchers from developing scientific taste and intuition. Read more →
- Commercial fusion is roughly three years away from demonstration, likely arriving before 2030 rather than in the proverbial thirty years. Read more →
- Google's Empirical Research Assistance (ERA) framework pairs LLMs with Monte Carlo tree search to automate experimentation, evolving out of attempts to automate Kaggle competitions. Read more →
