Thin Air

0.08%. Every month, atmospheric oxygen drops by 0.08%. Nobody notices — because nobody monitors atmospheric O₂. Six months later, when scientists finally sound the alarm, oxygen has already fallen from 20.8% to 20.3%. Doesn't sound like much? For a 1100MW coal power plant, that means combustion efficiency is starting to collapse. For the global nickel supply chain, that means the electrode material gap for electrolysis is 60%. For you, it means your next breath is slightly lighter than the last one. Thin Airis an English-language deep-dive podcast hosted by atmospheric chemist Dr. Marcus Webb, materials engineer Dr. Lila Patel, and behavioral economist Jake Donovan. Three friends from radically different fields, armed with banter, data, and an unhealthy amount of curiosity. They track a slow-motion apocalypse — not an asteroid, not a nuclear war, but the ocean itself stopping oxygen production, and the atmosphere thinning, breath by breath. From electrolysis to oxygen candles, from Sabatier reactors to solar-heated rocks — human technology degrades from industrial to manual, from manual to aerospace-grade sealed arks, from sealed arks to prehistoric stone and fire. Four phases, thirty episodes, six story arcs, global population from 8 billion to 5 million. A Chinese sci-fi novel calledAnoxic Worldthat Lila keeps mentioning offhand — until Episode 30, when you realize the book isn't fiction. It's a map.
