Summary

An original carbon-cost comparison chart plus a sane climate-action ethic. Scott quantifies the CO2 of dozens of activities/actors (heavily caveated as order-of-magnitude 'wild guesses'), and builds out offset economics — the order-of-magnitude gap between optimistic tree-offsets (~$15/ton, with all their failure modes) and pessimistic direct-air-capture (Climeworks ~$1000/ton), plus a '%Cost' statistic he candidly flags as gameable. The valuable payoff is the pragmatic ethic: offset (or better, donate to Clean Air Task Force) rather than 'boil yourself alive all summer,' vote for carbon taxes/nuclear/renewables, don't obsess over individual Climate Villains — plus a genuinely useful debunk of the '60 tons per child' figure down to a realistic ~2250 lbs. Sourced footnotes show real work.

Why this score

Quality 66 · Strong. Strong-floor (66). More than a roundup — an original quantification with sensible, memorable climate-ethics framing (offset-not-misery, the child-footprint debunk); held below the mid-Strong tier by its own admitted unreliability and the fact that it's a reference table plus advice rather than deep analysis.

Claude’s paradigm shift 46 · Moderate. Moderate (46). Assembling comparable carbon estimates and the offset-vs-donate framing is useful but not a novel frame.

Real-world impact 1 · Negligible. 1 — a personal reference/advice post; modest influence, no durable real-world effect.
