Abstract

fetched live from OpenAlex

In the October issue (p. 437), Mark Rasmussen in his letter does a creditable job of clarifying the issue of the ruminant contribution to global methane emissions. But in doing so he inadvertently offers up an even larger falsehood than the one he is correcting: that “the carbon dioxide emitted by ruminants contributes as much or more towards global warming than the methane expelled by these animals.” This is a confusion of gross and net fluxes. On an annual basis the CO2 emitted by animals is about equal to the CO2 taken up by the plants they consume, and net emissions are zero to a very good first approximation. Only land use change such as that associated, e.g., with conversion of forest to pasture constitutes a net source of atmospheric CO2.

Fetched live from OpenAlex and de-inverted. Abstracts are not stored in this database: the inverted indexes are 8.6 GB of the frame’s 9.3 GB of text, and the host has 13 GB free.

Full frame distilled prediction

Teacher imitation

Not calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)

The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.

Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
