Abstract
We examine climate change news coverage from 1997 to 2010 in two Canadian national newspapers: the Globe and Mail and the National Post. The following questions guide our analysis: Why did the volume of climate change coverage rise and fall during the period? Focusing on the key period of 2007–2008, what kinds of issue categories, thematic frames, and rhetorical frames dominate the news discourse? Canadian news coverage of climate change is characterized by a series of peaks and troughs, combined with an overall increase in coverage. The volume of coverage appears to be primarily driven by national and international political events, more than by changes to national or global carbon emissions, or by other ecological factors. The Canadian news discourse about climate change is dominated by themes of government responsibility, policymaking, policy measures for mitigation, and ways to mitigate climate change.

Full frame distilled prediction
Teacher imitationNot 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.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from it
