Summary

Short reasoning post debunking the 'melting-permafrost releases ancient plagues' climate-doomism scare. Applies epidemiological common sense (animal diseases rarely jump to humans; pre-human plagues implausible; anthrax and bubonic plague are red herrings) while taking seriously the genuinely worrying cases — a revived 1918 flu (which has since evolved away from its optimal point and 'lost the blueprint') and smallpox now that we stopped vaccinating — and notes the real vector is curious scientists digging up corpses.

Why this score

Quality 61 · Strong. Strong floor / Solid-Strong edge — a fun, competent, genuinely informative short piece (the flu-evolution 'lost the blueprint' argument is a nice reframe), but brief and casual with modest depth. 61.

Claude’s paradigm shift 42 · Moderate. Moderate — applies known epidemiology to a topical scare; little novel.

Real-world impact 1 · Negligible. Negligible material reach; a one-off blog debunking. 1.
