I had a more thoughtful and charitable post written up, but I reconsidered. What I have instead now is: if you're gonna say not even medical staff like surgeons should wear masks and that they're responsible for millions of stillbirths, you gotta do better than a survey of iffy CO2 levels under mask experiments and some hysterics about submarine CO2 levels. You need to measure blood levels. Like, if I were a researcher who wanted to get onto conservative media, this is the paper I'd write.

The whole publication is a joke. It goes on and on about breathing "2.8–3.2% carbon dioxide" when mask dead space constitutes maybe 15-30% of human tidal volume. At rest. And I'm pretty sure "2.8-3.2%" is a cherrypicked datapoint, other studies report lower concentrations. Realistically, all of this is less of an issue than classroom CO2 exposure over a schoolday but nobody's acting outraged about that one for some reason.
