Sasha Koenig

Dr. Sasha Koenig has spent eight years at Stratum-7, an atmospheric monitoring station in geostationary-adjacent orbit. She measures CO₂ concentrations, methane profiles, and the atmospheric chemistry of a planet that the official models say is recovering. The Paris III Accord is working. The aerosol injection programme has bought time. The curves are turning in the right direction. Then she gets an anomalous reading: 493.4 ppm CO₂ over a sector that should read 487.1. The instrument is calibrated. The methodology is correct. The anomaly doesn't resolve. *The Oxygen Statistic* is climate fiction thriller about the difference between the models and the measurements, between what we're told is happening and what's actually happening, between the recovery we've been promised and the managed decline that someone has decided is the best we can get. The novel unfolds across twenty-five chapters, following Sasha's investigation into an anomaly that turns out to be evidence of systematic data correction. The atmospheric monitoring network—the system she has spent her career believing in—has been calibrated to show recovery. The actual measurements show something else. The correction has been running for years. It has its own administrative structure. Its own funding. Its own justification: that accurate data would produce despair, and despair would accelerate the collapse, and managed decline with hope is better than accurate data without it. Sasha approaches the discovery the way she approaches everything: methodically, with documentation, by building the evidentiary case before drawing conclusions. She is a scientist. She believes in measurement, in verification, in the principle that better data leads to better decisions. What she discovers is that someone made a decision that better data would not lead to better decisions—that hope, even false hope, was a more valuable atmospheric constituent than truth. The station Stratum-7 is rendered with deep technical authenticity
