Reflections on the Catastrophic 2019–2020 Australian Bushfires
Bibliographic record
Abstract
While fire is an inherent part of the Australian landscape, the bushfires that occurred in eastern Australia from September 2019 to early February 2020 were unprecedented (Figure 1). Bushfires across the nation burned more than 12.6 million hectares (an area slightly bigger than Belgium, Denmark, and the Netherlands combined), emitted about 430 tonnes of carbon dioxide into the atmosphere (about three-quarters of the country's total annual carbon dioxide emissions), directly caused at least 33 deaths and over one billion animals were killed (https://www.abc.net.au/news/science/2020-03-05/bushfire-crisis-five-big-numbers/12007716).
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 machine prediction
Teacher imitationNot 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.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
