Abstract

fetched live from OpenAlex

Arctic sea ice is disappearing much faster than projected, and recent research indicates it could vanish entirely as soon as the summer of 2015. This change could in turn shift energy circulation across the northern half of the planet, altering jet streams, storm tracks, rainfall patterns and food production much farther south. Loss of sea ice will probably cause faster much melting of the Greenland ice cap and thus much faster rise in sea levels. These changes, along with three characteristics of anthropogenic climate change – nonlinearity, high uncertainty, long time lags – suggest that prudent climate policy must include major support for research to cool the planet’s poles.

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.

Not calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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.
